Response of pea (Pisum sativum L.) varieties to different fertility levels

A field experiment was conducted during 2008–09 to 2013–14 at Dewas to study the effect on pea (Pisum sativum L.) varieties to different fertility levels on growth and yield characters, uptake and balance sheet of nutrients, quality and economic viability. The results of experiments showed that the pea cv. ‘PSM-3’ recorded significantly higher plant height (43.36 cm), first picking (58.89 days), last picking (80.02 days), pod length (8.53 cm), pod width (1.39 cm), pods/plant (16.37), pod weight (5.09 g), grains/pod (7.79), weight of grains/pod (2.96 g), shelling (41.65%), biomass yield (45.25 q/ha), pod yield (67.79 q/ha), nitrogen uptake (124 kg/ha), phosphorus uptake (23 kg/ha), potassium uptake (87 kg/ha), sulphur uptake (21 kg/ha), zinc uptake (88 g/ha) and protein content (20.6%). Application of nitrogen: phosphorus: potassium: sulhpur: zinc significantly increased plant height (50.19 cm), first picking (59.19 days), last picking (77.88 days), pod length (8.41 cm), pod width (1.39 cm), pods/plant (16.53), pod weight (4.96 g), grains/pod (7.21), weight of grains/pod (2.90 g), shelling (41.46%), biomass yield (43.59 q/ha), pod yield (64.99 q/ha), nitrogen uptake (127 kg/ha), phosphorus uptake (24.5 kg/ha), potassium uptake (87 kg/ha), sulphur uptake (22.5 kg/ha), zinc uptake (71 g/ha) and protein content (20.2%) up to 25: 19: 13: 25: 7.5 kg/ha. Available nitrogen, phosphorus, potassium, sulphur and zinc in soil at harvest stage increased due to the application of these nutrients in soil.
