Technological interventions for commercial production of vegetable crops

The demonstrations in commercially important vegetables like cauliflower, cabbage, brinjal, chilli, okra, bittergourd, tomato and cucumber were conducted under Horticulture Mission for North East and Himalayan States (HMNEH, Mini Mission-I) and KVK, Dehradun Front Line Demonstration programme during the year 2010 to 2012 on farmers fields by KVK, Dhakrani (Dehradun) Uttarakhand. The result of the demonstrations revealed that introduction of high yielding varieties and hybrids alongwith timely management of various pests and diseases significantly increased the productivity of these vegetable crops. The varieties and hybrids introduced in demonstrations were Madhuri and Snow crown in cauliflower, Nilgiri and Varun in cabbage, Chhaya and Anamika in brinjal, Dushera and Lahar in chilli, Sanal, Sarika and VRO-6 in okra, Amanshree in bittergourd, Heemsohna in tomato and Malini in cucumber. The application of imidaclorpid, indoxacarb was found to be most effective in management of shoot and fruit borer in okra and brinjal and fruit borer in tomato. Incidence of wilt disease especially bacterial wilt was one of the serious problem which was managed by drenching of kasugamycine + carbendazim + copper oxychloride. Acaricide namely hexythiazox performed very well in management of leaf curl mite in okra and brnjal. Bait spray of malathion + molasses effectively minimized the incidence of fruit fly in cucumber and biottergourd. Technological interventions adopted in demonstrations showed outstanding performance in productivity of vegetable crops. Madhuri variety in cauliflower, Nilgiri hybrid in cabbage, Chhaya hybrid in brinjal, Dushera hybrid in chilli, Sonal hybrid in okra, Amanshree hybrid in bittergaurd, Heemsohna hybrid in tomato and Malini hybrid in cucumber gave maximum productivity and income.
