Effects of Foliar Applications of Some Macro and Micro Nutrients on Yield, Quality Attributes of Guava (Psidium Guajava L.)

Abstract

Effects of foliar applied macro (NPK) and micro nutrients (Fe, Mn, Zn, Cu and B) at different time on yield, quality and benefit: cost ratio of rainy and winter season guava were evaluated in north western Haryana, India. The two season’s data depicted that physico- chemical characters with respect to fruit set, fruit retention, fruit size, average fruit weight and yield were significantly increased with foliar application of macro and micro nutrients at vegetative, flowering and fruiting stage (T7). The shoot C: N ratio was also found highest with T7 foliar treatment which was followed by T5 in both the seasons. The T7 foliar spray resulted in maximum benefit: cost ratio in both the seasons. Proper fertilization strategies can help fruit growers to get good yield and quality fruits. Bangladesh J. Bot. 50(4): 1159-1164, 2021 (December)

Manipulation of flowering and fruiting induction through branch bending and fertilizer application in mandarin citrus cv. Batu 55

“…In citrus plants, the flowering phase will absorb a very high amount of N nutrients [31], whereas P is used in the flower formation process [32], and more K is needed for fruit development [33]. Based on a summary of a review [34], micronutrients are crucial chemicals that plants really need. One of the essential roles is in the stages of metabolism, among others including the respiration process, photosynthesis, and the formation of chlorophyll.…”
