Effect of different levels of NPK on the growth and yield of cucumber (Cucumis sativus) under the plastic tunnel.

Abstract

An experiment was conducted to check the effect of different levels of NPK on the growth and yield of hybrid cucumber. Application of NPK fertilizer (100-50-50) showed the best performance in almost all the parameters studied, as it took least days to flowering (39.33), fruit setting (11.55), maturity (7.88), maximum fruit per plant (35.5), maximum fruit length (18.36 cm), maximum fruit weight (136.03 g) and yield per hectare (60.02) tons. Application of NPK fertilizers @ 120-60-60 kg ha also showed some beneficial effect on some parameters including fruit weight (150.69 g) and vine length (3.85 m). Control plots showed un-satisfactory results regarding all the parameters.
