Abstract

A field experiment was conducted at KSNUAHS, Shivamogga, India during Kharif 2023 to evaluate the effect of nano DAP on the growth and yield of groundnut. The experiment was laid out in RCBD with twelve treatments and replicated thrice. Various levels and methods of nano DAP treatments were evaluated, among the tested treatments application of 100 per cent recommended dose of N & P along with seed treatment of nano DAP 2.5 ml kg-1 of seeds and one foliar spray of nano DAP 4 ml l-1 at 30 DAS (T11) recorded higher plant height (58.50 cm), number of branches (15.92), number of effective root nodules at 30 and 60 DAS (47.43 and 85.27 respectively), the yield attributes like number of pods plant-1 (53.40), test weight (42.48 g), pod yield (3562.5 kg ha-1), kernel yield (2659.73 kg ha-1), haulm yield (4301.47 kg ha-1) and shelling percentage (74.69 %) were also found significantly higher in the same treatment. It also recorded higher gross returns (2,16,980 ₹ ha-1), net returns (1,41,716 ₹ ha-1), and B: C ratio (2.88) compared to the recommended dose of fertilizers, 12.4 per cent increased pod yield was noted with nano DAP application. This increase in yield can aid in ensuring food security, while the environmentally friendly properties of Nano DAP support the practice of sustainable agriculture.

8 of 20 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
