Production Competence, Cost-effectiveness and Nutrient Uptake as Influenced by Diversenutrient Management in Summer Groundnut (Arachis hypogaea)

摘要

A field experiment was carried out during summer 2019 and 2020 at Zonal Agricultural and Horticultural Research Station, Hiriyur University of Agricultural and Horticultural Sciences, Shivamogga to study the influence of natural farming practices on growth, yield attributes and yield of ground nut in black soils. Pooled analysis of two years revealed that recommended dose of fertilizer significantly recorded higher pod (1969 kg ha-1), kernel (1516 kg ha-1) and haulm (3699 kg ha-1) yield as compared to other nutrient management practices. Similar trend was noticed in other yield parameters. Significantly higher nutrient uptake was observed in treatment receiving recommended package of practice i.e., nitrogen (101.75 kg ha-1), phosphorus (28.41 kg ha-1) and potassium (94.54 kg ha-1), respectively. However, the natural farming treatment receiving significantly recorded higher gross returns (Rs. 1,62,458 ha-1), net returns (Rs.1,14,063) and B:C ratio (3.36) as compared to other nutrient management practices. In 2019 and 2020 the same treatment recorded significantly higher growth, yield parameters and economics.
