Ch.Kirankumar, E.Karunasree and R.V.S.K. Reddy


The major constraint for low productivity of tomato in the tribal areas of west Godavari district of Andhra Pradesh is non adoption of recommended package of practices and lack of awareness about the Integrated Nutrient Management in tomato cultivation. To replace the conventional practices, Krishi Vigyan Kendra, Dr.YSR Horticultural University, West Godavari conducted 20 field demonstrations on Integrated Nutrient Management and improved production technologies with high yielding variety (Arka Vikas) during rabi season 2015 and 2016. Cultivation practices under demonstration comprises of soil test based fertiliser recommendation, use of improved high yielding variety, maintained recommended plant population, recommended dose of organic, inorganic and bio fertilisers, bio pesticides and control of pest and disease. An average yield of tomato in demonstration fields ranged from 194.50 to 215.55 q/ha whereas in local practice it is 161.85 and 172.65 q/ha during 2015 and 2016, respectively. It was recorded that the percentage increase in yield with high yielding variety over local variety was recorded in range of 20.17 to 24.84 %. Similarly, the extension gap ranged between 32.65 to 42.90 q/ha and enhanced the soil quality index during the years 2014 and 2015, respectively
