Abstract:

A field experiment was conducted during kharif 2013-14 and 2014-15 on Byadgi chilli by substituting fertilizer nitrogen with different sources of organic manures along with foliar application of water soluble fertilizers to study the micro nutrient uptake by chilli. The experiment consists of four main treatments as organics, M1- Recommended Package of Practices (RPP)- {Recommended Dose of Fertilizers (RDF) + 25 t ha-1 FYM}, M2- 50 per cent N through FYM + 50 per cent inorganic N, M3- 50 per cent N through VC + 50 per cent inorganic N, M4- 50 per cent N through FYM and VC + 50 per cent inorganic N and four sub treatments as water soluble fertilizers, S1- KNO3 @ 1 per cent, S2- K2SO4 @ 1 per cent, S3- 19:19:19 @ 1 per cent, S4- KNO3+ K2SO4+ 19:19:19 each @ 1 per cent along with one control (RPP + water spray) with three replications. The design adopted was split plot. Results revealed that combined foliar application of KNO3 + K2SO4 +19:19:19 each @ one per cent recorded highest capsaicin (0.14 per cent) and oleoresin (16.35 per cent) content and substitution of 50 per cent nitrogen through vermicompost + 50 per cent nitrogen through inorganics noticed higher iron uptake (852.9, 921.6 and 1010.9 g ha-1 at 75, 105 and 140 DAT respectively), zinc uptake (100.1, 104.9 and 147 g ha-1 at 75, 105 and 140 DAT respectively), manganese uptake (274.7, 383 and 408.9 g ha-1 at 75, 105 and 140 DAT respectively) and copper uptake (48.68, 49.56 and 51.35 g ha-1 at 75, 105 and 140 DAT respectively).
