TAILIEUCHUNG - Screening of tomato genotypes for various yield and quality parameters under regulated deficit irrigations in northern dry zone of Karnataka

Tomato is one of the most popular and widely grown vegetables in the world which ranks next to potato. Although tomato is generally grown under irrigated conditions, its cultivation as a rainfed crop has gained importance particularly in semi-arid regions. It has been established that stress due to water deficit is a very important limiting factor at the initial phase of plant growth and establishment. Studies on physiological evaluation of tomato genotypes is limiting in the drought stress condition. Hence, the present investigation was carried out to screen the tomato genotypes for various Number of fruits / plant, Average fruit weight, Equatorial diameter (mm), Polar diameter (mm), Pericarp thickness, Number of locules/fruit, Yield/plant Yield/ hectare, Carotenoid content, TSS, Ascorbic acid content, Lycopene content and yield potential by adopting simple field screenings with regulated two levels of irrigation at two different stages of plant growth to know the effect of drought on tomato genotypes. The experiment was laid out in a factorial randomized block design with thirteen genotypes and two replications. Water stress was imposed two weeks after the transplanting to all the genotypes in two stress conditions viz the IW/CPE ratio of , and farmers practice as control. | Screening of tomato genotypes for various yield and quality parameters under regulated deficit irrigations in northern dry zone of Karnataka
