Abstract
The present investigation was undertaken to study the “Response of pigeonpea to foliar spray of NanoZinc in an Inceptisol”. The experiment was conducted at Post Graduate Institute Research Farm, Department of Soil Science, Mahatma Phule Krishi Vidyapeeth, Rahuri, during kharif 2023. The experiment was laid out in randomized blockdesign (RBD) with three replications. The experiment consists of ninetreatments viz., (T1) - Absolute control, (T2) - GRDF (25:50:00 N:P2O5:K2O kg ha-1 + Vermicompost @ 1.5 t ha-1), (T3) - GRDF + Two foliar spray of water, (T4) - GRDF + Two foliar spray of Nano-ZnO @ 1000 ppm, (T5) - GRDF + Two foliar spray of Nano-ZnO @ 1500 ppm, (T6) - GRDF + Two foliar spray of Nano-ZnO @ 2000 ppm, (T7) - GRDF + Two foliar spray of Chelated-Zn @ 1000 ppm, (T8) - GRDF + Two foliar spray of Chelated-Zn @ 1500 ppm, (T9) - GRDF + Two foliar spray of Chelated-Zn @ 2000 ppm. As regards growth and yield attributing characters, the chlorophyll content in fresh leaf tissues at 40 DAS (49.38 SPAD value) and at 65 DAS (52.35 SPAD value), number of pods plant-1 (707.33),number of grains pod-1 (3.98), grain yield (38.9 q ha-1) and straw yield (123.59q ha-1) were recorded significantly the highest under treatment (T6) - GRDF + Two foliar spray of Nano-ZnO @ 2000 ppm. As regards quality parameters significantly the highest protein and test weight of pigeonpea was recorded (21.37% and 8.99 g) respectively in treatment of GRDF + Two foliar spray of Nano-Zn @ 2000 ppm. The same trend of total uptake of macronutrients N, P and K (199.32 kg ha-1, 42.16 kg ha-1 and 111.40 kg ha-1) , respectively and total uptake of micronutrients viz, Fe, Mn, Zn and Cu (2302.53 g ha-1, 1656.01 g ha-1 , 232.43 g ha-1 and 161.81 g ha-1), respectively were recorded significantly the highest in treatment of GRDF + Two foliar spray of Nano-Zn @ 2000 ppmwiththe highest gross monetary returns (Rs.365651/-), net monetary returns. However, the treatment of GRDF + two foliar spray of chelated Zn (EDTA) @ 2000 ppm at 30 and 55 DAS to pigeonpea was at par and recorded higher B:C ratio as compare to aforesaid treatment.
