ABSTRACT
A field experiment was conducted on alfisols during 2013 of Zonal Agricultural and Horticultural Research station, college of Agriculture, Navile, shivamogga. To study the effect of NPK application through different approaches on yield and secondary nutrient uptake by finger millet (Eleusine coracona L.) under rainfed conditions. A total of nine treatments were tried in a Randomized Complete Block Design (RCBD) with three replications. The treatments comprise of RDF + compost 10 t ha-1, RDF + 50 % NK + compost 10 t ha-1, STCR based NPK + compost 10 t ha-1, STL based NPK + compost 10 t ha-1,RDF through enriched compost, RDF + 50% NK through enriched compost, STCR based through enriched compost, STL based through enriched compost, with a control. The results revealed that application of STCR based NPK and compost 10 t ha-1 for targeted yield 40 q ha-1 recorded a highest grain yield (3238.00 kg ha-1) and straw yield (8926.00 kg ha-1). The percent deviation for targated yield of 40 q ha-1 (19.05 %) . Similarly higher uptake was recorded in STCR based NPK + compost 10 t ha-1 both in grain and straw. Total calcium and magnesium uptake by ragi crop was significantly higher in treatment receiving STCR based NPK and compost @ 10 t ha-1 T3 (67.55 and 44.43 kg ha-1) and lowest was in control (38.46 and 22.98 kg ha-1). Total S uptake (18.32 kg S ha-1), was recorded with the application of STCR based NPK and compost @ 10 t ha-1. The highest calcium and magnesium content (4.80 and 4.16 cmol (p+) kg-1) in soil was found in STCR approach (T3). The highest available sulpher (12.42 ppm), content was found where application of STCR based NPK and compost @ 10 t ha-1 (T3) and lowest sulphur content was found in control plot (2.12 ppm).
Key words: STRC, Target yield and STL.
