Influence of Integrated Nutrient Management on Flowering, Yield and Yield Attributes of Cucumber (cv. Hassan Local) under Open Field Condition

摘要

An experiment was carried out on influence of organic, inorganic and biofertilizers on yield and economics of cucumber (Cv. Hassan Local) grown under open condition at Department of Horticulture, University of Agricultural Sciences, Bangalore during the year 2005 and 2006. The results revealed that the plants treated with 75 per cent RDF + 75 per cent FYM + AZT + PSB + TD (T,) registered lowest number of days for male (30.00 30.40) and female (30.36 ; 36.00) flower appearance, lowest node of first male female (3.30 ; 3.16) flower appearance, lowest sex ratio (4.60; 4.88 %), highest fruit length (18.16 ; 20.81cm), fruit volume (295.61 ; 330.00 ml), fruit diameter (22.23 ; 22.40 mm), fruit weight (309.01; 324.94 g), fruit yield vine~(-1) (2.47 ; 2.55kg) and total fruit yield hectare1 (17.60 ; 18.22t ha~(-1)) during summer 2005 and rabi 2006 respectively. Whereas, the same treatment also recorded least number of nodes of first female (2.46) flower appearance and highest number of male flower (93.00)per vine during summer 2005, highest fruit cavity (4.55 cm) during rabi 2006. With this the treatment T_2 75 per cent RDF + 75 per cent FYM + Azotobacter + Phospobacteria + Trichoderma is identified as best for earliness and higher productivity. The highest benefit : cost ratio was recorded with T_4 (1:3.37) which was on par with T_8 (1:3.17).
