| dc.description.abstract | A field experiment was conducted during kharif 2012 in the farmer’s field at Agadi village in Dharwad district to study the “Response of Byadgi chillies to ferrous sulphate and zinc sulphate application in calcareous Vertisol in northern transitional zone of Karnataka”. The experiment consisted of ten treatments with three replications. Results showed that application of ferrous sulphate @ 25 kg ha-1 to soil on 30th DAT+foliar spray of 0.5 percent ferrous sulphate on 60th and 90th DAT recorded highest fruit yield (17.17 q/ha) closely followed by treatment that received soil + foliar application of zinc sulphate (16.60 q/ha). Ferrous sulphate applied treatments recorded comparatively higher fruit yield than zinc sulphate applied treatments. Highest colour value (274.23 ASTA units) and oleoresin content (18.07%) in red chillies were recorded with soil (25 kg/ha)+foliar (0.5%) application of ferrous sulphate. Foliar spray of zinc sulphate (0.5%) on 60th and 90th DAT produced minimum per cent discoloured fruits (5.26%) and treatments receiving only ferrous sulphate application recorded comparatively higher discoloured fruits than treatments receiving zinc sulphate application (T3 and T5). Control recorded maximum per cent discoloured fruits (6.12%). Combined foliar spray of ferrous sulphate and zinc sulphate (each 0.5%) at 60 and 90 DAT resulted in marginal decreased colour value (230.11 ASTA units) but numerical increase in discoloured fruits (5.54%) compared to individual foliar spray. Highest iron (196.63 mg/kg) and zinc (86.59 mg/kg) contents in red fruits were noticed in treatments receiving soil+foliar application of ferrous sulphate (T6) and zinc sulphate (T7) respectively. Potassium content of whole red fruits had a significant positive correlation with colour value (0.79**) and oleoresin content (0.81**). Iron and zinc contents of whole red fruits were positively correlated with colour value (0.65* and 0.63* for iron and zinc, respectively). Zinc content of whole red fruit possessed significant negative relationship with per cent discoloured fruits (-0.84**). Per cent discoloured fruits possessed significant positive relationship with leaf nitrogen content (0.66*), while potassium, iron and zinc contents possessed significant negative relationship. Highest B:C ratio (5.31) was obtained due to soil + foliar application of ferrous sulphate (T6). | en_US |
