Studies on the Effect of Foliar Application of Micronutrients and Ga3 on Yield and Reproductive Parameters of Winter Season Guava

The present investigation entitled “Studies on the effect of foliar application of micronutrient and GA3 on reproductive parameters and fruit yield of winter season guava “ was carried out in the Fruit Research Farm, Horticulture Unit, Banaras Hindu University, Varanasi during the year 2010–2011. The experiment was laid out in Randomized block design with eleven treatments.

Maximum fruit retention and minimum fruit drop was found in T4 (Borax-0.4%) while minimum results was recorded in under T11 control (no treatment isgiven) respectively. Maximum yield was recorded in Treatment T4 (Borax-0.4%) while minimum was under control.
