Effect of Different levels of Nitrogen, Phosphorus and Sulphur on Growth and yield of Rajmash (Phaseolus Vulgaris L.) Variety PDR 14

In the experiment four level of nitrogen (30, 60, 90 and 120 kg ha⁻¹), three levels of phosphorus (0, 30 and 60 kg ha⁻¹) and two levels of sulphur (15 and 30 kg ha⁻¹) were tested. The experiment was laid out in double split plot design with three replications accommodating 24 treatments combination in total 72 plots, allocated randomly in each replication. Rajmash variety PDR 14 selected as test crop for experimentation. Nitrogen at the rate of 120 kg/ha proved significantly superior to 90, 60 and 30 kg/ha in respect of all growth and yield attributes which recorded highest grain yield 14.06 ha⁻¹. Higher level of phosphorus i.e. 60 kg ha⁻¹ proved significantly superior to 30 kg/ha and control in respect of growth and yield attributes, which recorded highest grain yield 12.76 ha⁻¹. Sulphur application proved beneficial in bringing about significant improvement in yield attributes. 30 kg S ha⁻¹ produced highest grain yield 12.15 ha⁻¹.
