Abstract:
Guava (Psidium guajava L.) being most important cultivated species of Myrtaceae family. It ranks third in vitamin C content (260 mg/100 g) after Barbedose cherry (1500 mg/100 g) and Anola (700 mg/100 g). Guava is one of the most popular fruit of India. It is the fourth most important crop by area and production after mango, bananas and citrus. So, to find out Effect of different levels of Micronutrients on growth & flowering attributes of guava (Psidium guajava L.) fruit in meadow orchard; a field experiment was conducted at the Horticulture Research Farm, Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences (SHUATS), Prayagraj (U.P.) during the year 2021. The experiment comprised of 11 treatments of different levels of zinc & boron replicated thrice in a Randomized Block Design. The main objective of the experiment was to evaluate the influence of zinc and boron on growth & flowering attributes of guava. The levels of zinc & boron include 0.2%, 0.4%, 0.6%, 0.8%, 1% respectively. From the present investigation 1% boron was found best with, 5.80m Plant height, 6.38 primary branches per plant, 31.85 days required for flowering, 31.33 days required from flowering to fruit set, 126.52 days required from fruit set to maturity & 178.58 flowers per plant. These practices may be passed on to the farmers for obtaining higher returns in this agro-climatic zone.
