Several critical inputs, such as fertilizers and other chemicals, are exploited to address this challenge, creating environmental damage. Soil health has deteriorated, land degradation has occurred, and major environmental challenges have arisen as a result of intensive agricultural production without respect for environmental sustainability. As a result, future efforts to feed the world's growing population should prioritize increasing agricultural output while remaining ecologically responsible. In this sense, novel approaches are required, as current policies are incapable of addressing these issues. The notion of efficient nutrient management, which includes a variety of strategies for agricultural sustainability, as well as numerous soil and crop management strategies (SCMS) meant to maximise crop output under environmentally sustainable conditions, is addressed. Balanced fertilization, minimized use of chemicals such as fertilizers and pesticides, and improved crop input utilization efficiency could help reduce greenhouse gas emissions while simultaneously saving the environment. Sustainable agriculture holds promising applications for humanity and the environment, and it can be realised if industrialized and developing countries collaborate to establish a "shared vision" that produces more food with less ecological consequences.</strong></p> MONEESA BASHIR, M.

The starting materials for triple test cross was the F<sub>1</sub> and their grand parents (P<sub>1</sub> and P<sub>2</sub>) for the two studied wheat crosses. The first cross Gemmeiza 11 x Misr1 and the second cross was Gemmeiza 12x Misr2. The F<sub>1</sub>’s were selfed to produce F<sub>2</sub>’s grains. In order to create F<sub>1</sub> and F<sub>2</sub> plants, the obtained materials (F<sub>1</sub> and F<sub>2</sub> grain genotypes) and the parental genotypes were seeded together. Thirty individual F<sub>2</sub> plants were randomly labeled from each cross and crossed back to their grand parents (P<sub>1</sub> and P<sub>2</sub>) and F<sub>1</sub> between then to produce three types of families L<sub>1</sub> (F<sub>2i</sub> x P<sub>1i</sub>), L<sub>2</sub> (F<sub>2i</sub> x P<sub>2i</sub>) and L<sub>3</sub> (F<sub>2i</sub> x F<sub>1i</sub>) in each cross. On November 10, 2018, during the winter growing season, the triple test cross families (L<sub>1</sub>, L<sub>2</sub> and L<sub>3</sub>), along with the parents, F<sub>1</sub> and F<sub>2</sub> in each cross, were seeded. Results showed that in the genetic system for the investigated features for two crosses, epistatic gene effects were significant. The types of epistasis (additive x additive, additive x dominance and dominance x dominance) were significant for all studied characters. For the majority of traits in both crossings, both additive and dominant genetic components were significant and involved in the genetic system. The average level of dominance for spikes/plant in cross 1 and spike grain weight in cross -2 was overdominance, while for the remaining characters, additive gene effects were more pronounced. The F value was positive and significant for 1000-grain weight in two crosses, suggesting that dominant genes controlling these characters were unidirectional. The highest proportion of inbreds excepted to outperform parental rang in cross 1 for days to heading and flag leaf area. In both crosses, grain yield per plant was positively and significantly correlated with number of spikes per plant, number of grains per spike, and 1000-grain weight, according to epistasis, additive, and dominance genetic correlations.</strong></p> A.

Res. Inst., A.R.C., Giza, Egypt during 2020 and 2021 seasons to explore the response of <em>Jatropha curcas</em>&nbsp; plants to EM (effective microorganisms) which was applied as soil drench at 3 ml/L, 5 times with one month interval. Plants cultured in 25-cm-diameter plastic pots filled with sand only as control (T1), sand + plant compost 10 % mixture (T2), T2 + EM (T3), sand + plant compost 20 % mixture (T4), T4 + EM (T5), sand + plant compost 30 % mixture (T6) and T6+ EM (T7). The obtained results showed that means of the different growth parameters ;expressed as:&nbsp; plant height, number of leaves / plant , leaf area , root length , as well as fresh and dry weights of stem, leaves and roots were ascending increased as the ratio of compost was increased in the soil especially with EM treatments compared to means of control in most cases of the two seasons, otherwise stem diameter trait, which progressively increased with the middle ratio of compost (20 %) and compost (20 %) + EM followed by the highest one (30 %) and (30%) + EM reached to the lowest values of compost (10 %) and (10 %) + EM over control in the first and second season. A similar trend was also obtained regarding the leaf content of chlorophyll a, b, carotenoids beside the percentages of N and total carbohydrates which were recorded the highest values with sand + compost (30%) subsequent sand + compost (20%) and sand + compost (10%) individually or with EM. Whereas, the leaf contents of P% and K% significantly increased in sand + compost (20%), (30 %) and then (10%) whether with EM or without. Hence, it can be recommended to drench EM (3 ml/l) in sand soil mixed with plant compost (30 %) in which&nbsp; <em>J</em>. <em>curcas</em> plants are grown to keep good growth and the best quality plant.</p> REEM M.

Green leafy vegetables are rich sources of carotenoids (Vitamin 'A') as well as appreciable amounts of minerals such as calcium, phosphorus, potassium, sodium, iron, zinc, manganese and copper. In view of less utilization of some of tradition leafy vegetables by people of Banaskantha district and paucity of scientific information on nutritive value, it is proposed to assess nutritive value of less familiar, six underutilised green leafy vegetables <em>viz.,</em> dodi, poi, kanjaro, khatedo, radish and sarsiya for proximate composition. Healthy, six green leaves were randomly collected in fresh conditions from farmer’s fields of surrounding villages and subjected to analysis of different nutrients. At the end of the study it was found that Dodi (<em>Leptadenia reticulate) </em>and kanjaro<em> (Digera arvensis) </em>have high percentage of crude protein, ash and crude fibre as compared to other underutilized vegetables and hence can be used routinely as a part of diet to fulfil the nutrient requirement of&nbsp; peoples of Banaskantha region.</p> P.

An experiment was performed at Sakha Agricultural Research Station Farm, Kafr El-Sheikh Governorate, Egypt, to study the role of spraying commercial amino acids (g-plus) and pure tryptophan on forage yield and chemical composition of three Egyptian clover cultivars during the two successive winter seasons 2019/2020 and 2020/2021.</p> <p>&nbsp;The experiment was laid out in a strip-plot design with three replications. The main plots were occupied by amino acids treatments <em>i.e.</em> spray with water (control), spray with g-plus (5cm/l water) and spray with tryptophan at two concentration (200 and 400 mg/l). While sub-plots contained three cultivars of berseem; Helaly, Serw1 and Giza 6. The results showed that, the maximum total fresh forage yield, total dry forage yield, average of plant height, number of stem per 0.25 m<sup>2</sup>, fresh leaf/stem percent and dry leaf/stem percent were obtained for variety Helaly spraying by amino acid g-plus (5cm/l water). Also, the obtained results showed that, foliar spraying of amino acids caused significant increase of most physiological characters in comparison to the control. The highest values of chlorophyll content, relative water content (RWC %), protein % and NPK% were obtained with spraying g-plus. Concerning, the cultivars effects showed a wide range of variation in their productivity where, Helaly was the highest values of the most physiological parameters as well as yield and yield components. The interaction effects of foliar spraying of amino acids and cultivars showed that, Helaly treated with g-plus (5cm/l) gave the highest values of growth and physiological parameters.</p> A. S. M.

Drought tolerance is genotype dependent.&nbsp; The present study was conducted to investigate the effects of Water Deficit Stress (WDS) at flowering stage, genotype and their interaction on some agronomic, physiologic, grain yield and quality traits of 8 maize inbred lines and their 28 diallel crosses and also attempt to identify the maize genotypes tolerant to WDS conditions. The parents and F<sub>1</sub> crosses were evaluated in two seasons. A split plot design with three replications was used, where main plots were allotted to two irrigation treatments, i.e., Well Watering (WW) by giving all recommended irrigations and WDS by withholding the 4<sup>th</sup> and 5<sup>th</sup> irrigations, while sub plots were allotted to genotypes. Water deficit stress caused a significant decrease in grain yield/plant (32.3%), grain yield/ha (26.7%), ears/plant (30.6%), rows/ear (10.2%), kernels/row (9.3%), kernels/plant (43.8%), 100-kernel weight (19.9%), plant height (8.5%), ear height (11.9%), and chlorophyll concentration index (17.3%) and a significant increase in anthesis-silking interval (58.82 %), days to anthesis (4.29%), days to silking (6.40%), barren stalks (20.0%), and grain protein content (16.0%). On average, means across F<sub>1</sub> crosses were higher than those across inbreds for all studied traits, except for grain protein content and days to 50% silking, where the opposite was true, under both WDS and WW conditions. The rank of inbreds and crosses for studied traits under WDS was changed from that under WW conditions. The reduction in grain yield/ha of inbred lines due to drought (37.36%) was generally higher than that in F<sub>1</sub> hybrids (25.67%). It was possible to identify some inbreds and hybrids characterized by high yield and high tolerance to WDS conditions, which were recommended for use in breeding programs for improving drought tolerance in maize.</strong></p> AHMED MEDHAT MOHAMED AL-NAGGAR, AHMED MONGED SOLIMAN, ELHAM MOHAMED HASSAN MOHAMED ##submission.copyrightStatement## Tue, 18 Oct 2022 00:00:00 +0000 CLONAL VARIATION OF GROWING AND MAHOGANY (Swietenia macrophylla King) CLONE SELECTION IN AN ASEXUAL SEED ORCHARD <p><strong><em>Swietenia macrophylla</em></strong><strong> King.

Data showed that formulated chitosan nanoparticles 100 mg/L loaded with methionine 40 mg/L gave an excellent record of fruit number per plant and seed weight per plant, and the highest protein content combined with the lowest range of the toxic compound malondialdehyde. Additionally, applying chitosan nanoparticles 50 mg/L coated with methionine 40 mg/L to <em>D. innoxia</em> plants resulted in the highest accumulation of atropine alkaloid and several polypeptides in the protein electrophoresis (SDS PAGE) when compared with control. Furthermore, in the roots of <em>D. innoxia</em>, where tropane alkaloids are synthesized, this application induced the expression of the tropinone reductase 1 (DiTR1) gene, a key gene in the synthesis of tropane alkaloids.

The purpose of this study was to determine the larvicidal activities of selected mangrove plant extracts against <em>Aedes aegypti</em> mosquito larvae. Methanol extracts of three selected halophytes viz. <em>Lumnitzera racemosa</em>, <em>Bruguiera</em> <em>cylindrica</em>, and <em>Excoecaria agallocha</em> were made, phytochemically investigated and evaluated against <em>A. aegypti</em> early 4<sup>th </sup>instar larvae. Acetylcholinesterase (AChE) activity and Glutathione S-transferase (GST) activity were evaluated, followed by DNA extraction and fragmentation tests. GC-MS technique was used to determine the presence of bioactive chemicals. Alkaloids, flavonoids, terpenoids, anthocyanin, coumarins, phenolic compounds, and quinones were found in all&nbsp;plants. The best larvicidal activity was recorded in the <em>L. racemosa</em> flower buds (LC<sub>50</sub>- 0.766 mg/ml) and <em>E. agallocha</em> stem extract (LC<sub>50</sub>- 0.986 mg/ml).&nbsp; <em>L. racemosa</em> flower buds and<em> E. agallocha</em> stem exhibited higher inhibition in Acetylcholinesterase (AChE) activity with the rate of 1.39 μmol ACT/min/mg protein and 1.65 μmol ACT/min/mg protein (p &lt; 0.05) in treated larvae. In the case of <em>L. racemosa</em> flower buds, however, enhanced GST activity was detected. Plant extracts were found not to cause any fragmentation activity in the larval DNA. 5 major peaks of chemical compounds were analyzed in<em> L. racemosa</em> and <em>E. agallocha</em>. Because of the possible larvicidal action of selected halophyte extracts, they can be utilized as ecologically friendly mosquitocide for eradicating dengue vector larvae in their early stages.</p> PRATIK P.

The stalk rot of maize caused by <em>Fusarium moniliforme</em> (<em>Fm</em>) is one of the most important emerging threats to the successful production of maize in Pakistan. In this study the physicochemical characterization of <em>Fm</em> was done. Diseased samples of maize were collected from Faisalabad regions. Pathogen was isolated from the infected maize plant. In physiological test different pH levels (8.5, 7.5, 6.5 and 4) were evaluated and the highest fungal growth was observed at pH 7.5 (14.50mm), and the effect of different temperature (23, 28, 33, and 38) were also assessed. At 28°C temperature (38.42mm) the highest growth was observed. Different carbon sources (glucose, sucrose, dextrose, and maltose) versus were assessed. Glucose as a carbon source showed the highest fungal growth (11.62mm). Nitrogen sources such as urea, Ammonium nitrate (NH<sub>4</sub>NO<sub>3</sub>), and potassium nitrate (KNO<sub>3</sub>) were assessed, and urea showed the highest fungal growth (34.86mm). <em>Fm</em> was characterized by using biochemical tests such as cellulose hydrolysis, urease activity, β-glucosidase activity, phosphate, and polyphenol oxidases activity. All these biochemical showed the positive results except urease activity test. All the experiments were conducted under lab conditions by using Randomized Complete Block Design (CRBD). To observe the difference in response of treatments, least significant difference (LSD) was used at 0.05 % probability level.</p> MUHAMMAD KASHIF, MUHAMMAD ATIQ, NASIR AHMED RAJPUT, SHAHBAZ TALIB SAHI, FAHAD YAQOOB, MARIAM ASHRAF, TAHREEM FATIMA, AQSA GHAFFAR, TAHREEM AIMEN, HAMZA TARIQ ##submission.copyrightStatement## Wed, 07 Sep 2022 00:00:00 +0000 SUPERIORITY OF NANO-SILVER NITRATE AND NANO-CHITOSAN IN CONTROLLING BACTERIAL CONTAMINATION AND PROMOTING GROWTH OF In vitro DATE PALM CULTURES <p><strong>Date palm (<em>Phoenix dactylifera </em>L.) a perennial monocotyledonous tree it’s have an ecological importance and economical role in several countries of Middle East and North Africa, date palm can’t be propagate by seeds, meanwhile the offshoots produced low numbers of offshoots for the given period, so tissue culture technique become a great important for produced the huge demand plantlets, the in vitro technique facing a problem as the contamination by bacterial and fungus that lead to loss the cultures, for eliminate this problem many treatments were used as chitosan 5 and 15 ml/l, AgNO<sub>3</sub> 4.0 and 7.0 ml/l, Zn 4.0 and 7.0 mg/l and cu 0.5 and 1.0 mg/l. as the main forms or as a nanoparticles NPs in addition to streptomycin 40 and 50 mg/l and AgNO<sub>3</sub> + Sodium thiosulfate 0.5 and 1.0 ml/l were added to rooting stage medium for 3 subcultures for each, then these plantlets were acclimatized under greenhouse condition.

SPS catalyzes the formation of Sucrose-6-phosphate which is subsequently converted to sucrose. SPS is believed to have regulatory roles in sucrose biosynthesis through interaction with Serine Kinase, 14-3-3 protein and SPP. Nevertheless, the protein-protein interaction sites on SPS are not well characterized. This study focuses on identification of functionally important residues other than the catalytic residues in SPS through evolutionary trace analysis and structural mapping of key residues. We found that other than catalytic sites, many residues are absolutely conserved and are either buried or exposed. The exposed highly conserved sites are putative protein-protein interaction sites. We have also identified residues which are class specifically conserved in SPS4. Mapping of the class specific residues on SPS crystal structure revealed their distribution close to the catalytic site. Therefore, the class specific conserved sites in SPS4 can be predicted to be influencing catalysis.</p> D. P. SYAMALADEVI, AMALA DANDU, J. ROSHAN, S. M.

One type of corrosion, biocorrosion, is due to the action of microorganisms including fungi and more research concerning this cause of corrosion is needed. The aim of this manuscript is divided into two parts. Firstly, we use a Scopus bibliometric analysis of publications to develop a general overview of corrosion and biocorrosion research trends from 1900 to 2021. Secondly, using a deep analysis of all the Scopus recorded publications, we determine the different antifungal agents effective against <em>Penicillium cyclopium</em>, used here as an example of fungi involved in biocorrosion. The general overview demonstrates a clear progression and increase of number of publications in the two fields of corrosion and biocorrosion. However, from a total of 304,863 publications related to corrosion, only 1.5% are related to biocorrosion. The most studied metal is "steel" followed by "alloy'' and "aluminum". For microorganisms, the most studied are Sulphate-Reducing Bacteria (SRB) followed by Acid Producing Bacteria (APB), Sulfur Oxidizing Bacteria (SOB) and Iron Bacteria (IB). In relation to antifungal agents for the fungus <em>Penicillium cyclopium</em>, we found sixteen antifungal agents described in the literature. We hope this study may give scientists insights to further examine the potential for antifungal applications in the reduction and remediation of biocorrosion.</p> BENAMEUR NEHAR ##submission.copyrightStatement## Tue, 30 Aug 2022 00:00:00 +0000 ENCAPSULATION OF BANANA SHOOT TIPS FOR In vitro SHORT-TERM STORAGE AND GERMPLASM CONSERVATION <p>The present investigation is focused on the effect of different concentrations of sodium alginate and calcium chloride treatment on banana shoot tip (G-9) encapsulation for the formation of artificial seeds. For this, different concentrations of sodium alginate and calcium chloride were checked for optimum encapsulation. <em>In vitro</em> culture shoot tips of bananas were encapsulated by using different concentrations of sodium alginate i.e. (1%, 2%, 3% and 4%) and calcium chloride (50 mM, 75mM, 100 mM and 150 mM). Further, the storage viability of encapsulated shoot tips was also examined. Encapsulated shoot tips were stored at two different temperatures i.e., 4℃ and 25℃. Results indicated that the best alginate concentration for encapsulation was found at 3% (w/v) and 100 mM calcium chloride. The beads were formed globular, firm and found suitable for handling and exhibited a germination frequency of 93.33% on Murashige and Skoog medium supplemented with BAP and IAA (5.0 + 1.0 mg/l, respectively). The encapsulated shoot tips showed different responses after storage at different temperatures. The multiplication frequency declined for both tested storage temperatures i.e., 4℃ and 25℃. Encapsulated shoot tips stored at 4℃ showed survival for longer storage with a regeneration frequency of 91.33%, whereas, capsules stored at 25℃ resulted in rapid deterioration within 90 days and exhibited a maximum multiplication frequency as 61.66%. This indicates that storage at low temperatures is more effective. This study could be applied as an alternative method of banana micropropagation as well as germplasm conservation.</p> NITIKA VATS, ANKIT AGRAWAL ##submission.copyrightStatement## Wed, 24 Aug 2022 00:00:00 +0000
