Abstract:
The experiment entitled “effect of plant growth regulators and nutrients on fruit drop and yield of Kinnow mandarin” was carried out at Chaudhary Farm House, Village Malapur, Hisar during 2015-2016 to assess the effect of plant growth regulators and nutrients on fruit drop and yield of Kinnow mandarin. The treatments comprising of 2, 4-D 10, 15 and 20 ppm, GA<sub>3</sub> 10, 15 and 20 ppm, K<sub>2</sub>SO<sub>4 </sub>1%, 1.5% and 2% and ZnSO<sub>4 </sub>0.25%, 0.50% and 0.75% along with control were laid out in randomized block design with three replications. The result of investigation indicates that the foliar application of 2, 4-D 20 ppm was found quite effective in increasing final fruit retention and minimizing fruit drop. Fruit weight was recorded maximum in K<sub>2</sub>SO<sub>4</sub> 2% and number of fruits and yield were found maximum in treatment 2, 4-D 20 ppm.
