ABSTRACT
Wheat (Triticum aestivum L.) is one of the world's most essential cereal crops, serving as a staple food for a significant portion of the global population. In the pursuit of achieving higher yields in contemporary agriculture, the use of chemical fertilizers poses an increased environmental risk. However, the application of Nano urea offers a potential solution to mitigate this risk to a certain extent. To address this objective, a field experiment was conducted during the Rabi seasons of 2022-2023 at the A trial was executed in the rural area of Kanpur district of Mandhana, located 10 km from Kanpur in Uttar Pradesh, during the Rabi season of 2022-23. The experimental design involved two main factors: Factor-1 Nitrogen (at 50%, 75%, and 100% levels) and Factor-2 Foliar Spray (at one time Nano urea and two time Nano urea, with 4 ml/l). A control group was included, and the experiment was laid out in a Randomized Block Design (RBD) with 13 treatments in three replications. The results indicated that the combination of 100% nitrogen along with a foliar spray of 4 ml/L Nano urea had a significant positive impact on growth, yield, and various yield parameters. Treatment 6 demonstrated the highest values for plant height (95.66 cm), Dry matter accumulation (1014.09 g m-2), number of tillers m-2 (417.44), Leaf area index at 90 DAS (4.85), effective ear head per (m-2) (282.66), grains per ear head (65.75), test weight (48.52 g), grain yield (46.15 quintals/ha), and straw yield (57.92 quintals/ha). The study's results demonstrated a generally positive effect of combined Nano urea with traditional NPK nutrient supply on the growth and yield parameters of wheat in irrigated conditions.
ABSTRACT
Tomato (Solanum lycopersicum) is a widely cultivated and versatile fruit. Tomato production faces various constraints, both biotic and abiotic stresses. Fusarium wilt, caused by the soil-borne fungus Fusarium oxysporum f. sp. lycopersici, is a devastating disease that affects tomato plants worldwide, causing significant economic losses in tomato cultivation. Inthis study the potential use of biofortified vermicompost for wilt management was investigated. The biological control agents viz. Trichoderma harzianum, Pseudomonas fluorescens and Bacillus subtilis were used to fortified the vermicpompost. The study monitored various antioxidants, plant growth indicators, and disease rates across designated treatments at different intervals. The findings revealed substantial differences: tomato plants treated with biofortified vermicompost showed notable reductions in disease occurrence, improved growth, increased yields, and heightened antioxidant activity compared to the control. Among these treatments, the most remarkable outcomes were observed in plants treated with T. harzianum fortified vermicompost, exhibiting the highest recorded values across the parameters studied. Data revealed that the Tomato plants treated with vermicompost fortified with Trichoderma showed maximum root length (14.95 cm) after 15 days of sowing followed by T-2 (11.25 cm) and T-3 (9.85 cm). Maximum dry weight was observed in plants treated with vermicompost fortified with Trichoderma. Maximum PAL, PO and PPO activity was recorded in leaves from plant grown in vermicompost fortified with T. harzianum (T1) at 48 h followed by T2, T3 and T4. The findings revealed tomato plants treated with biofortified vermicompost showed notable reductions in disease occurrence, improved growth, increased yields, and higher accumulation of defense enzyme activity compared to the control.
ABSTRACT
Two lead treatments (flatbed and raised bed) and five nitrogen treatments (100 percent inorganic source, 100% farm yard manure, 50% inorganic source + 50% by farm yard manure, 75% inorganic source + 25% by farm yard manure, and 100% inorganic source + 25% by farm yard manure) were used in the triplicate study, which was conducted using a split plot design. The samples were analyzed 25, 50, and 75 days after sowing. The administration of treatment T3 (50% IO + 50% FYM) produced the tallest number of plants, as well as the most leaves per plant, weight per plant, and dry weight per plant, according to the results. On the shortest day, 50% tasseling was noted; nevertheless, this occurred with T1 (100% IO) application. Therefore, the combination of organic nitrogen sources with inorganic nitrogen sources in T3 (50% Inorganic + 50% Farm yard manure) with litter improved the performance of maize. It is recommended to use beds with 50% Inorganic + 50% Farm yard manure for crop growth.
ABSTRACT
A field experiment was conducted to investigate the effects of micronutrients on productivity and profitability of pea (Pisum sativum sub sp. hortense) at the Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, during the winter season of 2019- 2020. The experiment was laid out in the Randomized Block Design comprising of 9 treatments including control with different concentrations of boron and zinc applied to the pea crop viz., Control, Boron-20(0.06%), Boron-20(0.09%), ZnSo4 (0.03%), ZnSo4 (0.05%), Boron-20(0.06%) + ZnSo4(0.03%), Boron-20(0.06%) + ZnSo4(0.05%), Boron-20(0.09%)+ ZnSo4(0.03%) and Boron-20(0.09%)+ZnSo4 (0.05%) which were replicated thrice. Garden Pea variety “Azad Pea-3” was sown at row to row spacing of 30 cm x plant to plant spacing of 10 cm. The crop was uniformly fertilized by 20 kg N, 40 kg P2O5, 40 kg K2O /ha through urea and diammonium phosphate and muriate of potash. However, Zinc and boron was applied through zinc sulphate and borax as per the requirement of the treatments. The results indicated that the application B-20(0.09%) + ZnSO4(0.05%) recorded the highest quantity of seeds per pod (9.27g) number of pods per plant (25.63), yield per plant (64.23g), fruit yield (135.37 q/ha) which was closely followed by application of B-20(0.09%)+ZnSO4(0.03%). Further, application B-20(0.09%) + ZnSO4(0.05%) recoded higher B:C ratio (4.06) as compared to control (2.72). Thus, application of B-20(0.09%) + ZnSO4(0.05%) was found to the best treatment among all the treatments in improving the productivity of garden pea for the resource poor farmers of India.
