Influence of Micronutrients on Growth, Yield and Economy of Sapota cv. Kalipatti Under HDP System
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 3
Abstract
The field experiment was carried out to know the response of soil and foliar application of micronutrients (i.e. Zinc, iron and boron) on growth, yield and economic of sapota CV. kalipatti under HDP system at Kittur Rani Chennamma College of Horticulture, Arabhavi during 2015-2016. Zinc and iron sulphates are used for soil and foliar application, boron for soil application sodium tetraborate (Jai bore) and for the foliar application solubor were used. The results revealed that foliar application, 0.5% ZnSO4 + 0.5% FeSO4 + 0.3% B shows significant increase of plant growth, i.e. plant height (3.55m), spread (10.42 m2), tree volume (5.18 m3) and tertiary branches (134), yield (20.60 kg tree-1 and 23.44 t ha-1) and economy i.e. maximum BCR (benefit cost ratio) 3.49 and highest additional B/C (10.55) over control.
