Abstract

A field experiment was conducted during 2017 at Horticulture Research Farm-1, BBAU, Lucknow on 11- year- old guava plants, Studies on the Effect of foliar application of nutrients and plant growth regulators on physical parameter of guava (Psidium guajava L.) fruit cv. Lalit”, revealed that fruit set, fruit retention, fruit length, fruit width, fruit weight, fruit volume, specific gravity, fruit yield per plant (kg/plant) and yield (q/ha) were maximized when foliar spray was done with Urea (1%), Potassium sulphate (1%), Zinc sulphate (1%) GA3 50 ppm, and NAA 50 ppm.
