Effect of pollination time to improve physicochemical characteristics of ‘dhakki’ dates
Abstract
To assess the effects of different pollination times to improve physicochemical characteristics of Dhakki table dates, an experiment was conducted during 2012 and 2013 at Date Palm Research Orchard of Gomal University Dera Ismail Khan Khyber Pakhtunkhwa-Pakistan. The experiment was comprised of seven different treatments of pollination times i.e., at 1st, 2nd, 3rd, 4th, 5th, 6th and 8th days after spathe cracking and carried out in RCB Design having three replications. Single pollen source was used for pollination by inserting 3 male strands into the female spathe respectively. Different variables were recorded during the experiment that included fruit set (%), days to fruit set, fruit drop (%), days to maturity, Physicochemical characteristics and fruit yield (kg/tree). The results indicated that pollination times had a significant effect on all the parameters studied. Maximum fruit set (91.15, 90.15 %) and fruit yield (86.82, 87.15 kg palm-1) for both years were recorded when pollination was carried out on the 2nd day after spathe cracking. In delaying pollination average values of these parameters decreased. However, in late pollination at 8th days of spathe cracking produced maximum fruit length (4.26, 4.27 cm), fruit weight (21.20, 20.95 gm), and total sugars (17.91, 17.94 %). Based on these findings it can be suggested that pollination on the 2nd day after spathe cracking is the most effective for getting maximum fruit set and economical yield of Dhakki date palm cultivar.
