Effect of spacing and fertilizer level on growth, seed yield and resultant seed quality in pea (Pisum sativum L.) cv. Bonnevflle

摘要

The treatments with four spacings (2.5, 5.0, 7.0 and 10 cm between plants and a uniform spacing of 40 cm between rows) and three levels of NPK fertilizers (80:60:50; 120:80:70 and 160:100:90 kg ha~(-1)) were imposed on seed crop of pea (Pisum sativumL.) cv. Bonneville. Observations were made on days to first flowering, plant height, number of pods plant~(-1), pod yield plant~(-1), number of seeds pod~(-1), seed yield plant~(-1), shelling outturn and 100 seed weight. All the parameters were significantly influenced by spacings and fertilizer levels. With every increased level of NPK fertilizer and spacing, generally these characters showed favourble response. Germination potential, seedling growth, vigour index, dry matter production, electrical conductivity, protein content and free amino acids of the resultant seeds also have positive association with increased fertilizer levels and spacing.
