Effect of zinc sulphate and plant growth regulators on fruit retention, fruit weight and quality of litchi (Litchi chinensis Sonn)






Journal of Research, Punjab Agricultural University 24(2): 235-239

Effect of zinc sulphate and plant growth regulators on fruit retention, fruit weight and quality of litchi (Litchi chinensis Sonn)

In 2-year trials with the Dehra Dun, aqueous sprays of zinc sulphate at 0.5, 1.0 and 1.5%, GA3 at 50, 75 and 100 p.p.m. or NAA at 10, 25 and 50 p.p.m. were applied at 7-, 11- or 15-day intervals from the early stages of fruit development until harvest.

GA at 10-100 p.p.m., NAA at 50-150 p.p.m. or 2,4-D at 10-30 p.p.m. was applied to flower panicles of the cv. Muzaffarpore at full bloom (25 March). GA at 50 p.p.m. gave the best reduction of fruit drop followed by 2,4-D whereas NAA induced it.

Foliar sprays with zinc sulphate at 0.5, 1.0 or 1.5% considerably increased leaf Zn content. Zn was effective in reducing fruit drop, increasing fruit and pulp weight and TSS and decreasing total acidity.
