Abstract:

The field experiment was carried to evaluate the effect of foliar application of micronutrients viz. zinc, boron and copper in single and different combinations on guava (Psidium guajava L.) cv. Lalit for various reproductive parameters, at Horticulture Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Modipuram, Meerut, U.P. India during 2018-19. The experiment was laid out in Randomized Block Design comprised eight treatments with three replications. The maximum number of flowers per shoot (29.87), fruit set percentage (79.28%) and fruit retention percentage (63.20%) were found in treatment T8 (Zinc sulphate 1.0% + Borax 1.0% + Copper sulphate 1.0%) whereas the minimum values of above mentioned characters were observed in T1 (control). The maximum fruit drop percentage (50.53%) and days to fruit maturity (130.33 days) were recorded in T1 (control). However the minimum fruit drop percentage (36.8%) and days to fruit maturity (116.33 days) was recorded with foliar application of Zinc sulphate 1.0% + Borax 1.0% + Copper sulphate 1.0% (T8).
