Assessment of Nutrient Requirement in Little Millet under Central Dry Zone of Karnataka

Abstract

A field experiment was conducted in Patrehalli, Tiptur taluk, Tumkur district of Karnataka where soil was deficient in available potassium, to study assessment of nutrient requirement in little millet under central dry zone of Karnataka. The experiment was laid out in RCBD design comprising 3 treatments replicated seven times. Treatment details are, T1: Control, T2: FYM +NPK (20:20:0 kg ha-1) - UAS Bengaluru, T3: FYM+ 30:15:15 kg ha-1 - UAS Dharwad. The results revealed that significantly higher grain and straw yield (2.14 q ha-1 and 15 q ha-1) and also recorded highest nutrient available of nitrogen, phosphorus and potassium (197, 35 and 136 kg ha-1) by little millet was recorded in treatment which received 30: 15: 15 kg N: P2O5: K2O ha-1 along with FYM at 6.25 t ha-1 as compared to control. The results of the present study evidently concluded that the application of 30: 15: 15 kg N: P2O5: K2O ha-1 along with FYM at 6.25 t ha-1 under rainfed condition is beneficial for getting higher yield of little millet as well as higher benefit cost ratio (15.00) as compared to the control in low potassium soils of Tumkur district of Karnataka.
