Effect of fertility levels and foliar nutrition in fieldpea (Pisum sativum) under south - eastern Rajasthan

An experiment was conducted during the winter (rabi) season of 2016–17, 2017–18 and 2018–19 at Agriculture University, Kota, Rajasthan, to evaluate effect fertility levels foliar nutrition on fieldpea (Pisum sativum L.). The consisted 3 recommended dose fertilizers (RDF) (75%, 100% 125%) 5 sprays [water spray, neem-coated urea 2%, NPK (19 : 19 19) 0.5%, (17 44 0) 0.5% (0 0 50) 0.5%] pre-flowering pod-initiation stages. Result revealed, that maximum significantly higher plant height (168.21 cm), branches/plant (3.12), nodule count (23.75), dry weight (35.87 g/plant), pods/plant (61.90), seeds/pod (3.78), grain yield (2350 kg/ha), net returns (`52,889/ha) benefit cost ratio (3.02) were recorded with application 125% RDF (25 kg N + 50 P 25 K S 6.25 Zn/ha) 7.32, 10.64, 13.54, 11.40, 15.81, 12,17, 26.82, 32.18 16.60% increase over 75% RDF. Application nutrient content (N 3.30 0.54 1.18 0.40% in seed 1.69 0.48 1.51 0.31% straw) uptake 77.57 12.59 27.68 9.42 kg/ha 58.14 16.35 51.99 10.67 other treatments. Among applications, @ pod- initiation stage resulted (167.76 (3.14), (23.77), (36.36 (63.43), (3.89), (2,250 (`50,835/ha) benefit: (3.06) rest treatments 9.69, 12.95, 8.69, 10.06, 23.38, 18.24, 12.84, 17.19 15.47% control; however, it par results stage. Similarly, NKS straw observed under than
