Description |
A field experiment was conducted to study the effect of iron-EDTA on yield and quality of red chilli (Capsicum annuum L.) in a calcareous Vertisol at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during kharif 2007. The experiment was laid out in a randomized block design with twelve treatments and three replications. Soil application of Fe-EDTA equivalent to FeSO4 at 20 kg/ha + 0.5% Fe-EDTA foliar spray at 50 DAT recorded highest fruit yield (10.5 q/ha), ascorbic acid (178.90 mg/100 g) and highest uptake of nitrogen and phosphorus at final picking stage. This was on par with all treatments receiving soil + foliar application of Fe-EDTA but differed significantly from control which recorded lowest values (7.65 q/ha, 127.61 mg/100 g). Highest colour value (228.73 ASTA units), oleoresin (16.76%), potassium, sulphur and iron uptake were recorded in treatment receiving soil application of Fe-EDTA equivalent to FeSO4 at 20 kg/ha + 0.5% foliar spray of Fe-EDTA at 50 and 90 DAT. This was on par with all treatments receiving both soil + foliar application of Fe-EDTA but differed significantly from control (163.16 ASTA units and 13.03%). Total and ferrous iron contents analysed in dry and fresh green leaves on 5th day after Fe-EDTA foliar spray respectively indicated a significant positive relationship with colour value and oleoresin contents. |
