Effect of Integrated Nutrient Management on Dry Matter Accumulation and Uptake of Nutrients by Cucumber (cv. Hassan Local) in Eastern Dry Zone of Karnataka

摘要

Studies on Integrated Nutrient Management on the dry matter accumulation and uptake of nutrients in cucumer (cv. Hassan Local) revealed that application of 75 per cent RDF + 75 per cent FYM +Azotobacter (5 kg ha~(-1))+ Phosphobacteria (5 kg ha~(-1)) +Trichoderma (5 kg ha~(-1)) (T_2) recorded maximum total dry matter production (199.95 ; 227.41g/vine) which was on par with T_6 (190.50 ; 217.31 g/vine), T_1 (188.10 ; 212.18 g/ vine), T_4(188.16 ; 215.46 g/vine), T_7(183.10 ; 203.15 g/vine), T_8(182.88; 199.66 g/vine) and T_(10) (175.16 ; 196.68 g/vine) during summer 2005 and rabi 2006 respectively. Similarly the maximum uptake of N (19.58 ; 27.47 kg ha~(-1)), P (11.16 ; 8.23 kg ha~(-1)) and K (42.12 ; 50.69 kg ha~(-1)) was found with the vines provided with 75 per cent RDF + 75 per cent FYM + Azotobacter + PSB + Trichoderma (T_2) which was on par with T_4, T_1 and T_6 during both the seasons of summer 2005 and rabi 2006 respectively. The minimum dry matter accumulation and (158.05; 164.51 g/vine) and N (13.89 ; 15.43v kg ha~(-1)), P (6.48 ; 5.17 kg ha~(-1)) and K (22.02 ; 29.74 kg ha~(-1)) uptake was registered with 100 per cent FYM + Azotobacter + PSB + Trichoderma (T_(12)).
