ABSTRACT
This study was conducted at Horticultural Research Centre and department of Horticulture, HNB Garhwal University, Srinagar (Garhwal), UK, India. The experiment was carried out for two successive years 2005 and 2006 during the rainy season (Ambe Bahar) of guava cv. Lucknow-49 (Sardar Guava). The experiment consisted of 22 treatment combinations of 3 micronutrients viz., zinc sulphate, copper sulphate and boric acid at 0.2%, 0.3% and 0.4% alone and in combination of two and three except spray of plain tap water as control. The maximum fruit set and fruit volume was recorded under foliar application of zinc sulphate at 0.4%. The minimum fruit drop and improved fruit retention, fruit length and diameter, fruit weight and fruit yield were associated with combined spray of zinc sulphate + copper sulphate + boric acid spray at 0.4%.
Key words :
Fruit set, fruit weight, guava, micronutrients, Lucknow-49, quantitative characters.
