Abstract
A field experiment was carried out at the Horticultural Research Farm of the Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University during the Rabi season of 2012–2013. The experiment was laid out in Randomized Block Design with 9 treatments, replicated thrice and one branch was taken as a unit. Observations were recorded on growth, physical and quality characters of guava. The maximum fruit set percent (67.43) and fruit drop percent (58.71) were recorded maximum with foliar application of zinc sulphate + borax 0.6% and zinc sulphate+copper sulphate + borax 0.5%. Therefore, zinc sulphate + borax 0.6 percent and zinc sulphate + copper sulphate + borax 0.5% may be recommended to guava growers for obtaining better yield and quality during winter season crop of guava cv. Allahabad Safeda under Lucknow conditions.
Highlights
Guava (Psidium guajava L.), is one of the most important fruit crop
It is obvious from the foliar spray of micronutrients proved significantly effective in improving the fruit set percent
It was noticed that the fruit drop percentage reduced to the highest in T7 which was closely followed by T6 while highest fruit drop percent (58.71) was observed under control (T1)
Summary
Guava (Psidium guajava L.), is one of the most important fruit crop It is one of the most important tropical/ sub-tropical fruit, because of its high nutritive value and possibilities of cultivation even under adverse conditions.
