S. C. NAGANAGOUDA, K. MANJAPPA

Abstract


A field experiment was conducted during summer-2015 at AgriculturalResearch Station (Paddy), Sirsi on sandy clay loam soil to study theeffect of nutrient management practices in enhancing productivity ofaerobic rice in hill zone of Karnataka. There were 11 treatmentcombinations having spray of two different water soluble fertilizersviz., 19:19:19 and 13:0:45 (0.5%) ; soil application of micronutrientsviz., zinc as zinc sulphate (25 kg ha-1) and boron as borax (2 kg ha-1)along with recommended dose of fertilizer (RDF) (75:75:87.5 kg N,P2O5 and K2O ha-1) and RDF + Farm Yard Manure (FYM) (10 t ha-1).Among the different treatments, treatment having foliar spray of19:19:19 (0.5 % at 45, 60 and 75 DAS) along with RDF + FYM +ZnSO4 + borax has recorded significantly higher grain and straw yield(3765 and 4420 kg ha 1, respectively) and also higher gross and netreturns (` 65,321 and 33,436 ha-1, respectively) and was foundsignificantly superior over all other treatments except the treatmentswith foliar application of either 19:19:19 or 13:0:45.
