Aims: To evaluate the performance of tomato crops grown in four different media in a bell siphon arranged aquaponics system. Study Design: completely randomized design. Place and Duration of Study: Hi-tech Research and Training Unit (HTR&TU), Instructional Farm (IF), Kerala Agricultural University, Vellanikkara from 03-08-2021 to 03-01-2022 and 01-02-2023 to 30-06-2023. Methodology: An aquaponic system was equipped with twenty-four media beds with bell siphons, three filter tanks (sedimentation tank, mechanical filter, and biofilter), three fish tanks having 1000L capacity each, a submersible pump, and two aerators. Two hundred genetically improved farmed tilapia (GIFT) fingerlings were grown in the fish tanks. Four types of media, viz., 20mm gravel (M1), 8-20mm broken tiles (M2), 8-15mm hydroton (M3), and 8-10mm gravel (M4), were filled in the media beds. The two varieties of tomato, Manulakshmi and Yakamoz RZ, were raised. Plant height, plant spread, days to first flowering, days to first harvest, total yield, and average fruit weight were observed to compare the crop performance in each media and identify the best-performing media in an aquaponics system. Results: During the first and second seasons of Manulakshmi in the aquaponics system, plants grown in 8-10mm gravel exhibited significantly superior results than all other media. The maximum plant spread (66.833cm), plant height (140.556cm), total yield (1.730Kg), and average weight of fruit (38.433g) were observed in 8-10mm gravel during the first season. In the second season of Manulakshmi, the observed plant spread, plant height, total yield, and average weight of fruit were 140.778cm, 66.556cm, 1.729Kg and 38.611g, respectively. In the first season of Yakamoz RZ in the aquaponics system, maximum plant height (145.222cm) and total yield (3.871Kg) were observed in 8-10mm gravel, whereas maximum plant spread (50.500cm) was observed in 20mm gravel. The days to first flowering and days to first harvest were comparatively shorter in 8-10mm gravel in both varieties. Conclusion: Plants grown in 8-10mm gravel exhibited superior results than all other media. Variations of plant characteristics among different media in the aquaponics system reveal that 8-10mm gravel is more favorable for the growth and yield of tomato plants than other media.

Out of the 1.5 billion ha (11% of the world’s land surface of 13.4 billion ha) of cropland worldwide, 1.20 (80%) billion ha is rainfed, and 60 percent of the world’s food comes from rainfed areas. In India, rainfed agriculture occupies about 51 percent of the country’s net sown area and accounts for nearly 40 percent of the total food production. In HP, over 10% area of the state is under cultivation, of which about 81% is rainfed, facing frequent water scarcity. Watershed development constitutes a holistic strategy aimed at enhancing the resilience and productivity of rainfed farming systems. This approach integrates various interventions targeting soil and water conservation, afforestation, agricultural practices, and socio-economic empowerment of local communities. The essence of watershed development lies in its comprehensive and participatory nature, which addresses the complex interactions among hydrological, ecological, and socio-economic factors influencing rainfed agriculture. Through the implementation of watershed management techniques, such as contour bunding, check dams and afforestation, soil erosion is minimized, water resources are conserved, and micro-climatic conditions are ameliorated. Concurrently, sustainable agricultural practices, including agroforestry, conservation agriculture, and water harvesting techniques, are promoted to enhance farm productivity and diversify livelihood options for farmers. Moreover, watershed development programs prioritize community involvement and capacity building, fostering local ownership and empowerment. This abstract elucidates the multifaceted benefits of watershed development in revamping rainfed farming systems, emphasizing its potential to mitigate environmental degradation, enhance agricultural resilience, and improve rural livelihoods.

Soil is a non-renewable resource that performs many vital functions. Over-exploitation of soil by farmers leads to soil degradation such as acidification or organic matter lost. To find sustainable soil fertility management techniques, three types of organic matter (compost, compost combined with fungi, bacteria and yeast, and biochar) were applied to the soil. This study evaluates and compares the effect of various organic amendment on the soil fertility under pepper. A field trial was carried out in a randomized block design with four treatments (T0, T1, T2 and T3) and repeated three times in the Agboville department, located in Côte d’Ivoire. Growth and productivity parameters were measured during the experiment. At the end of the experiment, soil and plant samples were taken for chemical analysis and to determine soil fauna. The results show that the various treatments had little impact on soil chemical parameters. As for the soil fauna, results indicated a low level of biological activity under all treatments. However, a comparison of organic matter types shows that the compost-based treatment (T1) had a relative positive impact on pepper growth and production parameters, compared with the biochar treatment (T3), microorganism-based compost (T2) and control (T0) treatments. With a view to intensifying pepper production, it would be advisable to continue this work with long-term experiments while increasing the doses of organic matter applied to the soil.

Insufficient soil phosphorus has been the most important factor affecting rice yield under the rice grown conditions. KMR-3R is a popular restorer line used for commercial rice hybrids production. For majority of the rice ecosystems, most of the rice hybrids released using three line systems were suited for normal phosphorus conditions only which exhibits severe yield reduction under low phosphorus conditions. To facilitate the efficient use of complex polygenic traits in hybrid rice, molecular breeding approaches were developed using KMR-3R BILs with Pup1 QTL by introgression of major QTL Pup1 controlling genes yield under low phosphorus stress. Parental polymorphic survey is a pre requisite before starting marker assisted backcrossing, it is used for introgression of a desirable traits from a donor genotype into a recipient genotype. In this context, I have screened all reported SSR primers linked to low phosphorus tolerance and observed K-46-1 and K-46-2 linked to Pup1 QTL was polymorphic between Kasalath and KMR-3R. Simultaneously I have screened 300 full-genotype SSR markers covering entire genome and observed 86 SSR primers as polymorphic between Kasalath and KMR-3R. After polymorphic survey, I have evaluated Kasalath and KMR-3R.under low phosphorus stress and normal phosphorus conditions and recorded significant differences among the parents. Kasalath performed well when compared to KMR-3R for all the characters studied under low phosphorus stress conditions. With the generated genotypic data, a linkage map can be constructed which will further ensues the identification of a new markers linked to low phosphorus stress.

The present study was carried out at Agricultural Research Station, Mugad, Karnataka during kharif 2023 using augmented block design in upland condition using sixty advanced breeding lines of rice (Oryza sativa L.) and six checks viz., IR64, BPT 5204, DRR Dhan 45, Kagisali and Chittimutyalu to evaluate genetic variability for yield component traits and grain quality traits, to evaluate the association of yield with quality traits and to validate the genotypes for quality traits using SSR markers. Analysis of variance revealed the presence of significant differences among the genotypes for all the traits under study. Genotypic and phenotypic coefficients of variances were high for number of productive tillers per hill and grain yield depicting the wide range of variation for these traits. High heritability allied with high genetic advance over mean was seen for the traits like plant height, number of tillers per hill, number of productive tillers per hill, panicles per sqm, grain yield, grain iron content, zinc content and protein content indicating the preponderance of additive gene action and least influence of environment on these traits, thus, they possess better scope for improvement through selection. The correlation analysis revealed the negative significant association of grain yield with grain zinc content and negative non-significant association with all other quality traits. Validation of the putative markers is generally carried out to check the reproducibility of those markers. SSR markers RM211 and RM242 were validated for grain iron content, RM303 and RM234 for grain zinc content and RM23914, RM1235, RM219, RM206 and RM1337 for grain protein content. Therefore, these markers can be further used for effective biofortification of rice.
本研究在卡纳塔克邦穆加德农业研究站（Agricultural Research Station, Mugad, Karnataka）进行，采用扩增区组设计，使用 60 个水稻（Oryza sativa L.）先进育种品系和 6 个对照（即 IR64、BPT 5204、DRR Dhan 45、Kagisali 和 Chittimutyalu），于 2023 年印度旱季在高地条件下进行，以评估产量成分性状和谷物品质性状的遗传变异，评估产量与品质性状的关联，并使用 SSR 标记验证品质性状的基因型。方差分析显示，所研究的所有性状在基因型之间都存在显著差异。每丘丰产分蘖数和谷物产量的基因型和表型变异系数都很高，表明这些性状的变异范围很广。株高、每丘分蘖数、每丘丰产分蘖数、每平方米圆锥花序、谷物产量、谷物含铁量、含锌量和蛋白质含量等性状的遗传率较高，平均遗传进率也较高，这表明这些性状主要受加性基因作用的影响，受环境影响较小，因此通过选育有更好的改良空间。相关性分析表明，谷物产量与谷物锌含量呈负相关，与其他品质性状呈负非显著相关。对假定标记进行验证通常是为了检查这些标记的重现性。谷物铁含量的 SSR 标记 RM211 和 RM242、谷物锌含量的 SSR 标记 RM303 和 RM234 以及谷物蛋白质含量的 SSR 标记 RM23914、RM1235、RM219、RM206 和 RM1337 已通过验证。因此，这些标记可进一步用于水稻的有效生物强化。

The field trial was conducted at Krishi Nagar Farm, Department of Agronomy, College of Agriculture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh, India, during the kharif season of 2021. The field experiment comprised six treatments and was conducted in a randomized block design (RBD) with four replications. Results showed a slight reduction in soil pH in treatments 100% Organic NM, 50% Organic NM + NF inputs BJG, 50% Organic + 50% Inorganic NM, and 25% Organic + NF inputs BJG + 25% Inorganic NM, while an increase was observed in T5 and T6 compared to the initial soil status. Changes in EC and OC under various treatments were not significant, but available N, P, and K levels varied significantly across treatments, showing increased values from the initial soil status. The treatment with 100% Organic NM had the highest cost of cultivation (Rs.31624), gross monetary return (Rs. 58605/ha), net monetary return (Rs. 26982/ha), and B:C ratio (1.85), followed by the treatment with 50% Organic NM + NF inputs.

The present investigation was conducted to identify sources of tolerance to the herbicides viz., Topramazone and Quizalofop ethyl in order to potentially employ these sources in the development of herbicide-tolerant chickpea genotypes. Screening of genotypes revealed large variation in tolerance to Topramazone. Three genotypes namely, NBeG 776, RVG 205 and IPC 2010-134 were identified as highly tolerant based on herbicide tolerance scores and can be used as source for breeding Topramazone tolerant varieties. Herbicide Quizalofop ethyl showed non phytotoxic effects on chickpea genotypes. Also high yield of genotypes KGD 99-4 and NBeG 776 in presence of Quizalofop ethyl application suggested effective use of this post emergence herbicide to control weeds in chickpea.
