Abstract

A field experiment was conducted at Main Centre for Integrated Farming System Research located at Agricultural and Horticultural Research Station, Kathalagere, Davanagere (Karnataka), India comes under the Southern Transitional Zone of Karnataka (Zone-7) during summer 2007 to 20012 under protective irrigation condition of Bhadra Command area to study the effect of integrated nutrient management on growth, yield, uptake of nutrients and economics of groundnut production. The results revealed that application of 100% NPK+secondary and micro-nutrients based on soil test (10 kg ZnSO4 ha-1) has recorded higher dry pod yield (1953 kg ha-1), kernel yield (1555 kg ha-1), haulm yield (3617 kg ha-1), harvest index (0.57), net returns (Rs. 71717) and benefit cost ratio (2.34) as compared to all other organic farming practices. This might be due to higher growth and yield attributes such as plant height (57.86 cm), number of branches plant-1 (7.20), pods plant-1 (30.12), dry pod weight (29.32 g plant-1), 100 pod weight (28.50 g) and shelling percentage (79.64). Thus, the treatment receiving 100% NPK+secondary and micro-nutrients based on soil test (10 kg ZnSO4 ha-1) is better for realizing higher growth, yield attributes, yield and net returns as compared to all other organic farming packages.
