Influence of pollen source, complimentary pollination and micro-nutrients on productivity of kiwifruit cv. Hayward

Abstract

The present study was carried out on eleven year old vines of Hayward (female cultivar) and Tomuri and Matua (male cultivars) at Zangam orchard of Department of Horticulture (JandK) trained on T bar trellis system. The fruit set and yield characteristics of Hayward were significantly influenced by the pollen source. Among the various treatment combinations irrespective of the source of pollen, hand pollination at 90% bloom + spray of 0.1% borax (Na2B4O7.10H2O) and 0.4% ZnSO4 enhanced both fruit set and yield characteristics. Tomuri cultivar proved to be a good pollen source for desired fruit characteristic, and hand pollination supplemented with boron and zinc exhibited beneficial effects on all the afore-mentioned parameters of pistillate cv. Hayward.
