Abstract
A comparative study of pollination methods effect on the changes in fruit yield and quality of date palm cultivar Khalas
Highlights
Date palm (Phoenix dactylifera L.) is grown in arid and semi-arid regions on 1.34 million hectares and produced 8.17 million tons of fruit across the globe (FAOSTAT, 2017)
There was a non-significant effect of different pollination methods on the total No of fruit nodes per bunch
Maximum fruit set (85.71%) was recorded in pollen suspension method followed by pollen dusting method (82.07%), as both were statistically at par minimum fruit set (26.03%) was observed when female flowers were left to open pollination
Summary
Date palm (Phoenix dactylifera L.) is grown in arid and semi-arid regions on 1.34 million hectares and produced 8.17 million tons of fruit across the globe (FAOSTAT, 2017). Failure of effective pollination leads to the formation of triple parthenocarpic fruits of no economic value (Zaid and de Wet, 2002) To tackle this problem, artificial pollination is considered to be important to improve crop productivity and quality, which is commonly practiced in commercial date palm plantations (Gupta et al, 2017). Khalas yield was higher in mechanical dusting pollination, but with lower fruit length and weight than the hand dusting pollination This effect was not significant in cv. The traditional date palm growers in Saudi Arabia mostly practice conventional strands placement method of pollination or they leave the tree to allow natural pollination and are unaware of the other improved techniques. Keeping in view the importance of date palm pollination methods, a study was designed to compare the effects of different pollination techniques on fruit set, yield and physicochemical attributes of date palm cv. Khalas under the arid agro-climatic condition of Al-Ahsa, Saudi Arabia
