Effect of different levels of fertigation on yield, quality and leaf nutrient status of litchi (Litchi chinensis Sonn.) cv. Rose Scented

Fertigation significantly improved yield and quality characters of litchi. Maximum fruit retention (47.21%), yield (43.03 kg/tree) and minimum fruit drop (52.79%) was recorded in treatment ID₂F₂ (Drip discharge at 0.75 V + 125% recommended doses of fertilizers under microirrigation). Fruit cracking was reduced by different levels of fertigation and minimum fruit cracking (5.08%) was recorded under treatment ID₁F₃ (1.0 V drip discharge + 137.50% recommended doses of fertilizers under micro irrigation). ID₁F₃ also recorded maximum fruit length (3.97cm), width (3.16cm), weight (21.35g) and volume (20.62 cc). Leaf nutrient status was also affected significantly by different levels of fertigation.
