Abstract:
A line × tester analysis of twenty four hybrids developed by crossing four lines and six testers were carried out under three diverse environments. The components of genetic variance were estimated from the analysis of variances for combining ability of different characters for each environment and pooled also. The analysis of variance for combining ability individual as well as pooled over environments revealed that mean squares due to lines and testers were significant for most the characters, Line × Tester was significant for all the characters except seed yield per plant and estimated genetic variance due to GCA and SCA was non-significant for all the characters in pooled over environments. The ratio of σ2gca/σ2sca was less than unity which revealed the predominant role of non-additive gene action for inheritance of the traits for days to flowering, days to maturity, number of nodes up to primary raceme, effective length of primary raceme, seed yield per plant and 100-seed weight. Therefore, heterosis breeding may be suggested to exploit hybrid vigour and recombinant in F2 and subsequent generations for isolating lines for seed yield and its contributing traits. The line SKP 126 and tester SKI 420 were found as good general combiners for the yield attributing characters in pooled over the environments. Among the crosses, best three specific combiner were SKP 120 × SKI 420, SKP 126 × SKI 357 and SKP 106 × SKI 412 for seed yield per plant and its contributing traits.
Keywords: Combining ability, Gene action, GCA, SCA.

Abstract:
Zero Budget Natural Farming (ZBNF) is an agricultural method that does not require external inputs. This study, based on secondary data, analyses the number of farmers practicing natural farming and the land area under cultivation, as well as the prospects and challenges of ZBNF in Himachal Pradesh. The study reveals that Kangra district had the highest farmer adoption rate (22.33 per cent) under ZBNF, while Lahaul-Spiti had the lowest (0.46 per cent). Mandi had the largest area under ZBNF (24.61 per cent), and Lahaul-Spiti the smallest (0.71 per cent) from 2018-19 to 2022-23. The percentage growth rate of area under ZBNF was observed to be 156.20 per cent, and for the number of farmers, it was 1069.58 per cent from 2018-19 to 2022-23, indicating overall increases in both farmers’ adoption and area expansion for ZBNF practices. A high positive correlation of 0.9681 has been found between the number of farmers and the area under ZBNF. The study underscores the need to target more farmers and expand the cultivation area under ZBNF, as it is crucial for protecting soil fertility, providing healthy and chemical-free food. Therefore, the government and stakeholders should promote ZBNF and offer technical knowledge on best practices.

Abstract:
Hybrid rice is the primary cereal crop in Southern China, playing a crucial role in national food security. With a yield advantage of 15–20% over inbred varieties, agronomic practices. Planting density including inter-plant spacing and the number of transplanted plants per hill has a fundamental effect on rice production. However, the impact of transplanting plant numbers per hill on the expression of hybrid vigor remains unclear. This study evaluates the effects of different transplanting densities under sparse planting conditions on key physiological and yield-related traits in hybrid rice, its paternal lines, and inbred varieties. Results indicate that transplanting plant numbers per hill significantly influence heterosis, affecting key traits such as better-parent heterosis (BPH), plant height (PH), spikelets per panicle (SPP), seed setting rate (SSR), harvest index (HI), and overall yield. The optimal transplanting density for maximizing yield was 1–2 plants per hill for hybrid rice and 3–4 plants per hill for inbred varieties. These findings provide a theoretical foundation for breeding, high-yield cultivation, and the mechanized adoption of hybrid rice.

Abstract:
Irish potato is the only tuber crop grown by farmers in Lesotho, particularly in the foothills where environment is conducive for its growth and high yield. Potato seeds are imported from South Africa without verifying for authenticity, fraudulence and intellectual property rights. The objectives of the study were to: (i) estimate genetic distance among potato cultivars using morphological markers, (ii) determine discriminatory power of morphological markers in distinguishing potato cultivars. The study was conducted at National University of Lesotho experimental farm, Roma. Experiment was laid out using Randomized Complete Block Design with eight treatments and three replications. Treatments were cultivars; Mondial, Panamera, Taurus, Tyger, Tyson, Valor, Avalanche and Innovator. Data on 21 markers were collected using potato descriptor, thereafter analyzed using Genstat (Version 17) to perform cluster analysis and principal component analysis. Results of cluster analysis revealed variability among potato cultivars. Cultivars constituted 1 major group, which in turn divided into two sub-group. Two sub-groups further sub-divided three times forming sub-subgroups and outliers. First six principal components contributed 97% of variation among cultivars. Characters with high discriminatory power were marketable tubers, root fresh weight, tuber fresh weight, number of main stems, leaf dry weight, leaf fresh weight and total yield. In conclusion, cluster analysis has group cultivars according to their similarities and principal component analysis revealed characters with high discriminatory power.

Page No: 47-52
Abstract:
Ageratum conyzoides, commonly known as billygoat weed or goatweed, poses a significant threat to agricultural ecosystems, negatively impacting crop productivity and biodiversity. Due to environmental concerns associated with conventional control methods, this comprehensive review critically examines the current state of biological control strategies for A. conyzoides. The study explores three major categories of biological control agents: insects such as the Ageratum gall fly (Procecidochares utilis) and the Ageratum stem-boring weevil (Listronotus setosipennis), which disrupt weed growth through gall induction and stem boring, respectively; fungal pathogens that induce diseases compromising weed vigor; and herbivorous livestock, particularly controlled grazing by goats and sheep, as a natural means of suppression. The review evaluates the efficacy of these agents while considering key environmental factors such as climate and soil characteristics. Special emphasis is placed on minimizing non-target effects through host specificity assessments and optimizing biocontrol implementation strategies. Additionally, challenges including the potential development of resistance in A. conyzoides, the necessity of integrating multiple control measures, and existing knowledge gaps are discussed. This study underscores the importance of continued research and the adoption of integrated pest management (IPM) approaches to achieve sustainable and ecologically sound weed control. In conclusion, this review provides valuable insights into eco-friendly weed management practices, contributing to sustainable agricultural production and biodiversity conservation.
Keywords: Ageratum conyzoides, biological control, weed management, insect pests, pathogens, sustainable agriculture, environmental conservation.

Digital Identification Number: IJOEAR-JUN-2025-14
Page No: 53-56
Abstract:
To optimize sowing time, spacing and topping schedule for quality mesta seed production, an experiment with three dates of sowing [21st May (D1), 5th June (D2) and 21st June (D3)], three spacing treatments [30 x 10 cm (S1), 45 x 10 cm (S2) and 60 x 10 cm (S3)] and two topping schedules [30 DAS (T1) and 45 DAS (T2)] were laid out in split-split-plot arrangements with three replications. Different yield attributing characters and seed yield of roselle was significantly influenced by date of sowing and spacing arrangements.
It was observed that sowing dates influenced different growth parameters as well as yield significantly. D2 sown crop recorded maximum seed yield (6.4q ha-1) and statistically at par with D3 (6.17q ha-1).Similarly spacing arrangements also had a significant impact seed yield of roselle, with highest seed yield of 6.4q ha-1 obtained under 45×10 cm spacing followed by 60×10 cm spacing (6.28q ha-1).Topping done at 45 DAS resulted in 5.3% higher yield than that of 30 DAS. Yield attributing characters were not significantly influenced by topping schedules. Maximum net return of above Rs 27,000/ha was obtained, when the crop was sown on 5th June, with 45cmX10cm spacing and topping scheduled on 45 DAS with a B:C ratio of 1.76.Hence, it can be suggested that, sowing of mesta (roselle) during 1st week of June to third week of June with 45 x 10 cm and topping at 45 DAS should be recommended to harvest maximum quantity seeds in east and south eastern coastal plain zone of Odisha.
Keywords: Roselle, topping, seed yield, sowing time, spacing.

Abstract:
Environmental sustainability is a key component of resilient agricultural systems, particularly in integrated dairy-based farming where livestock interacts closely with the ecosystem. This study assesses environmental sustainability through nine indicators: animal health, housing conditions, calf raising, use of dung, water management, drought preparedness, disposal of packaging, urine management, and animal carcass disposal. Based on responses from 100 dairy farmers, findings show that while indicators such as animal health and dung use scored high, weaknesses were noted in drought preparedness, water management, and waste disposal. The Environmental Sustainability Index (EnSI) for the farms ranged from 0.22 to 0.84, with the majority categorized as moderately sustainable. These results underline the importance of targeted interventions to enhance sustainability in dairy-based systems.

Abstract:
During the ginning of seed cotton, the seeds can be broken and mixed into the fibers. The number of seed coat particles passing into the fibers and the amount of neps caused by the seed coat is an important factor that negatively affects the yarn quality and creates problems in dyeing. In this study, 200 different cotton genotypes were evaluated in terms of 100-seed weight, seed coat ratio, seed coat thickness and seed coat resistibility. As a result of the study, it was determined that 100-seed weights of genotypes varied between 7.23 – 15.43 g, seed coat ratios between 15.53 – 38.27%, seed coat thickness between 0.41 – 1.00 mm and seed coat resistibility between 41.07 – 107.21 newton. TxNo:142 genotype had the highest seed coat resistibility. In addition, it was determined that there was a positive and significant relationship between seed coat resistibility and 100-seed weight. In principal components analysis, two out of 4 principal components were selected with Eigen value >1. The two principal components contributed 59.3% towards variability. In cluster analysis, 200 genotypes were allocated in five clusters. Cluster II was the largest by having 90 genotypes while cluster V, cluster III, cluster I and cluster IV having 54, 28, 20 and 8 genotypes, respectively.

Abstract:
This study investigates the effect of varying levels of macro nutrients on the growth and development of spinach (Spinacia oleracea L.) using a Completely Randomized Design (CRD) with two varieties: Sindhi and English spinach. Conducted during 2024, the experiment utilized a total of six nutrient combinations, including control, NPK (3g/L, 4g/L, 5g/L), and Calcium Nitrate (1g/L), applied to two per pot across replicated treatments. Parameters such as seed germination percentage, germination index, plant height, leaf metrics, root characteristics, and chlorophyll content were assessed. Results indicated a significant enhancement in growth metrics with NPK (3g/L) plus Calcium Nitrate (1g/L), particularly for Sindhi spinach, where it exhibited a germination rate of 95.16% and an increase in chlorophyll to 64.86. Conversely, higher concentrations of NPK negatively affected germination and growth in both varieties, suggesting that balanced nutrient application is crucial for optimal spinach development. This investigation underscores the importance of macro nutrients in enhancing spinach yield, contributing valuable insights for growers aiming to maximize crop productivity.

Abstract:
Healthy soil is the crucial factor required to meet the global demands for food and fibre for the burgoining population. However, global food security is threatened by climate change impacts. Climate change, variability, and mismanagement or misuse of resources lead to soil degradation and vulnerability. Hence, sustainable soil management aims for the services of soil to be maintained without significantly impairing the soil functions that enable those services or biodiversity. Sequestering higher carbon in soils will help the soil increase its resilience to climate change in the long run. Therefore, every step towards sustainable soil health management in the climate change scenario should focus on soil carbon sequestration. The soils under different land use systems have various carbon sequestration potential. Adoption of the best management practices like conservation tillage (minimum, zero/no-till), balanced fertilization, green mulching, crop residue management, cover cropping, organic manures and in-situ soil and moisture conservation measures in agricultural lands can improve the carbon sequestration potential. The amount of carbon stored in forest soils is often greater than aboveground in living and dead plant biomass. Managing forests to optimize carbon sequestration is also essential to increase the carbon in forest soils. Carbon sequestration is the global mission achieving this is possible only through local vision involving the farmers, researchers and common public as agricultural/ forest soils and trees have the tremendous potential to sequester atmospheric carbon. Focus on soil health management to mitigate the climate change impacts is indispensable to have a sustainable ecosystem with high biodiversity.
Keywords: climate change, soil health, soil degradation, soil carbon sequestration, sustainable soil management, land use systems, soil organic carbon, carbon loss, conservation tillage.

Abstract:
The major purpose of this study is to determine the abundance golden apple snail in rice duck pig farming system. Weekly mean abundance of golden apple snail on the rice field fluctuates during the first four weeks of the experiment, gradually decreased during the succeeding weeks until the final week of the experiment. The graphical representation of each weekly mean per treatment shows the obvious decreasing significance of the golden apple snail in the rice field. Stocking densities of ducks decreased every week starting from week 4 of the experiment. The cause is not clear, but the weather can be considered as one of its causal factors since the experiment was done during rainy season. However, even if the stocking densities of ducks decreased, the abundance of golden apple snail decreased during the final weeks. The presence of duck in the rice field is effective in minimizing the abundance of golden apple snail. Distributed ducks in the rice field fed on the golden apple snails that are present in the soil which resulted to the decrease and elimination of the snails. Through this event, the field doesn’t need the application of any type of insecticides because the pests were reduced.
Keywords: Golden Apple Snail, Rice-Duck-Pig Farming System, Stocking Density.

Abstract:
Corncob is a readily available agricultural byproduct, is often underutilized despite its abundance and potential in animal nutrition. This study evaluates the effect of solid-state fermentation on the nutritional composition of corncob to enhance its value as a feed ingredient, particularly for monogastric animals such as poultry and swine. Results indicated that fermentation markedly reduced crude fiber and anti-nutritional factors like phytates, improving digestibility and phosphorus bioavailability. These enhancements indicates that fermented corncob could be an alternative feed resource to conventional feed stuffs, contributing to sustainable livestock production, reduced feed costs, and better utilization of agro-industrial waste. Its incorporation into animal diets aligns with circular agriculture practices and supports resource-efficient feed development. However, the analysis also resulted in reductions in crude protein, fat, and ash content, while calcium levels remained low before and after fermentation, indicating the need for either improved fermentation methods or dietary supplementation to ensure balanced nutrition.
Keywords: Agricultural byproducts, Digestibility, Fermentation, Nutrient composition, Sustainability.

Abstract:
The field experiment was carried out during Kharif, 2024 at Instructional FarmB1 Block (Agronomy), Rajasthan College of Agriculture, MPUAT, Udaipur. The experiment laid out under Factorial RBD design with three replications. The two factors were soil and foliar application of zinc sulphate heptahydrate. Soil application of zinc sulphate included 4 levels i.e. control, 6.25 kgha-1, 12.5 kg ha-1 and 25 kgha-1 and 4 levels of foliar application i.e. control ,0.25% ZnSO4.7H2O, 0.50% ZnSO4. 7H2O and 0.75% ZnSO4.7H2O. The major challenge of was that how supply the balance diet to rural people and mitigate the problem of micronutrient deficiency in soil. Soil and foliar utilization of zinc increased significantly yield and Yield Attributes but the harvest index was found non-significant. The Protein content and chlorophyll content also increased significantly. The highest values were found with soil application of 25 kg ZnSO4.7H2O and foliar application of 0.75% ZnSO4.7H2O which was further at par with 12.5 kg ZnSO4.7H2O and 0.5% ZnSO4.7H2O respectively. Judicious soil and foliar application of zinc increase the Zinc status in soil as well as in grain of maize.
