Abstract:
A field experiment was conducted at International Horticulture Innovation and Training Center, Durgapura (Jaipur) during two successive years 2018-19 and 2020-21 to investigate the effect of pruning intensity and foliar spray of micronutrients on growth and yield of guava (Punica granatum L.) cv. Allahabad Safeda under semi-arid conditions of Rajasthan. The experiment included 24 treatment combinations comprising three levels of pruning intensity (0, 25 and 50%) and eight levels of micronutrients Zn, B and Fe (0.4% each) with laid out in Factorial Randomized Block Design with three replications. The results revealed that use off micronutrients (Zn, Fe and B) with pruning intensity significantly increase the plant growth (gain in plant and plant spread) and yield attributes (fruit equatorial and polar diameter, fruit weight, fruit volume and fruit yield per tree). Interactions of pruning intensity 25% (P₂) and micronutrient ZnSO₄ @ 0.4% + H₃BO₃ @ 0.4% (M₅) (P₂M₅) gave best results with respect to plant growth and yield of guava.
