Crop regulation on kinnow decline

Scarcity of irrigation water in critical growth stages of the crop is one of the major causes of low productivity and decline of citrus orchards. Regulated deficit irrigation (RDI) is a recently proposed water saving technique in irrigated agriculture. The present study was planned with a hypothesis that the optimal RDI scheduling at early fruit growth period (EFGP), which coincides with summer months could save substantial amount of water, without significantly affecting the yield of ‘Kinnow’ mandarin plants.

Crop regulation studies were undertaken on Kinnow trees of 8th and 9th year which have started declining due to heavy crop load in the previous year to maintain the tree health and vigour for continuous production. Plano-fix (NAA) was used to thin the fruitlets in 0, 250, 300 and 350 ppm at fruitlets stage after fruit set. The experiment was laid on Randomized Block Design, replicated four times, two trees served as a unit of treatment. Applications of 350 ppm Plano-fix (NAA) decreased crop load via fruitlet thinning. It improved vegetative growth, tree vigour, fruit size & quality.
