Type: article
Abstract: A field experiment was conducted to study the Response of greengram to soil and foliar application of zinc in southern dry zone of Karnataka during early kharif 2018 at Junjanahally, Hassan. Experiments consist of nine treatments replicated thrice with RCBD. Results revealed that significantly higher growth and yield parameters such as plant height(71.93 cm) number of branches per plant(4.37), number of effective nodules per plant(28.07) dry matter production per plant (27.07g), pod length (13.60 cm) number of pods per plant(24.40), number of seeds per pod (13.40), pod weight per plant (29.73g),seed yield (1022.99kg/ha) and haulm yield (2544.93kg/ha) were recorded with T9 (soil application of zinc sulphate @ 10 kg/ha + foliar spray of zinc EDTA at 1.0 percent along with NPK and FYM). The available nitrogen, phosphorus and potassium content of soil were non significant however higher nitrogen and potassium recorded (239.80& 177.10 kg/ha) in the treatment T1(NPK+FYM) and lower nitrogen and potassium recorded (232.70 &171.40 kg/ha)in T9 (T3 + FSZn EDTA @1.0%). Higher phosphorus recorded in T9 (44.70 kg/ha). As regard to DTPA extractable micronutrients in soil , low iron (7.69 mg/kg),copper (0.369ppm),manganese (8.16 ppm) and Boron (0.35 mg/kg) content in soil was recorded in T9 (T3+ FS of Zn EDTA).Application of zinc increased carbonate bound zinc (3.14mg/kg), , organic bound zinc (1.73 mg/kg) and Fe and Al oxide bound zinc (2.84 mg/kg) was recorded in T3 (T1+ SA of ZnSO4 @10 kg/ha) over with NPK+ FYM. The higher total zinc was observed in the treatment T9 (130.42 mg/kg) which received T3+ FS of Zn [email protected] percent followed by treatment T7(135.32 mg/kg) and lowest Zn content was recorded (130.42 mg/kg) in the treatment T1(NPK+FYM).
