Abstract

The investigation entitled “Effect of foliar feeding of plant growth regulators and nutrients on leaf nutrient status of Guava (Psidium guajava L.) cv. Gwalior-27” was carried out in the Fruit Orchard, Department of Horticulture, R.V.S.K.V.V, CoA, Gwalior district of Madhya Pradesh during mrig-bahar of 2021-22. The field experiment was laid under FRBD (Factorial randomized block design) which contain 20 treatments and were replicated thrice. The result indicated that the leaf nitrogen content (%) as well as leaf calcium content (%) was affected significantly. The highest N content (2.74%) and leaf calcium content (0.75%) were found with M3 (Ca(NO3)2 2%). However, the plant growth regulators and nutrient spray individually and their interactions both had non-significant effect on both leaf P as well as K content. Maximum leaf boron content (90.67 ppm) and leaf zinc content (60.58 ppm) was obtained with M1 (Borax 0.4%) and M2 (ZnSO4 0.5%) respectively. Therefore, based on the experimental findings it can be concluded that foliar feeding of PGR’s and nutrients was an effective way for enhancing the leaf nutrient status of guava. The effect of nutrients was found to be effective in maximising the leaf N content, leaf boron content, leaf zinc content and leaf calcium content significantly. Although, foliar feeding of various concentrations of PGR’s and nutrients independently as well as their interaction effect did not impact any change in the leaf P and K content of the leaf.

Keywords: PGR’s, nutrients, foliar feeding, plant nutrient status, FRBD
