Validation of STCR approach of nutrient application for carrot on Alfisols of eastern dry zone of Karnataka

Abstract

A field experiment was conducted during kharif 2017 at Devanahalli village, Bengaluru rural district to validate STCR approach of nutrient application for carrot on Alfisols of Eastern Dry Zone of Karnataka. The results revealed that significantly higher root yield (27.51 t ha-1) was recorded in STCR target of 25 t ha-1 through integrated approach. The per cent deviation of 10.03 under STCR targeted yield of 25 t ha-1 through integrated approach indicates that this equation is a best equation for zone 5 of Karnataka as the per cent deviation was within ± 10.00.
