Studies on the Effect of Plant Spacing and Graded Levels of Nitrogen, Phosphorus and Potassium on Yield and Yield Components of Mid Season Garden Pea (P1Sum Sativum L.)

Response of mid season garden pea (Pisum sativum L.) var. Bonneville to plant spacing (30 × 5, 30 × 10 and 30 × 15 cm) and graded doses of nitrogen (25, 50 and 75 kg N/ha), phosphorus (25, 50, 75 and 100 kg P2O5/ha) and potassium (25 and 50 kg KaO/ha) was studied on silt loam soil during the winter seasons of 1982 and 1983. at the Central Horticultural Experiment Station, Ranchi, Bihar. The highest yield was recorded at the closest spacing (30 × 5 cm). There was significant and increase in yield upto 50 kg N per ha and 50 kg P2O2 per ha. Response to potassium was not observed.
