Effect of phosphorus and zinc sulphate on yield attributes and quality of guava (Psidium guajava L.) cv. Gwalior 27

Abstract

An experiment was conducted during 2013 to find out the effect of phosphorus, zinc sulphate and their combined effect on yield and quality of Guava (Psidium guajava L.) cv. G-27. The experiment was laid out in Randomized Block Design (RBD) with thirteen number of treatments replicated thrice in well established 15 years old plant of guava. There were four levels of phosphorus i.e., 300 g, 400 g, 500 g and 600 g., three levels of spray of zinc sulphate i.e., 0.25%, 0.50% and 0.75%, while the control plants received no fertilizer and no spray. The study revealed that 600 g phosphorus per plant, spray of 0.75% zinc sulphate (P4xZn3), followed by P3 X Zn3 (P2O5 500 g/ plant & ZnSO4 @ 0.75 %) were found to be the best treatments for almost all yield and quality parameters of guava plant, for getting maximum yield with quality fruits in northern Madhya Pradesh.
