Abstract:
A field experiment was conducted Effect of phosphorus and zinc on growth and yield of field pea (Pisum sativum) during the rabi season of 2021-22 with 9 treatments (viz., P at 55, 60, 65kg/ha respectively and Zn at 10, 15, 20 kg/ha respectively) at the CRF (Crop Research Farm) SHIATS, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh. The treatments comprised T1 – 55 kg P/ha + 10 kg Zn/ha, T2 – 55 kg P/ha + 15 kg Zn/ha, T3 – 55 kg P/ha + 20 kg Zn/ha, T4 – 60 kg P/ha + 10 kg Zn/ha, T5 – 60 kg P/ha + 15 kg Zn/ha, T6 – 60 kg P/ha + 20 kg Zn/ha, T7 – 65 kg P/ha + 10 kg Zn/ha, T8 – 65 kg P/ha + 15 kg Zn/ha, T9 – 65 kg P/ha + 20 kg Zn/ha. Application of 65 kg P/ha + 20 kg Zn/ha recorded highest plant height (94.16 cm), plant dry weight (15.28 g/plant), number of branches/plant (9.56), number of pods/plant (20.09), length of pod (7.34 cm), seed index (126.08 g), seed yield (2.41 t/ha), stover yield (3.33 t/ha), gross returns (144600 INR/ha), net returns (99910 INR/ha) and B:C ratio (2.23).
