RESPONCE OF SOIL AND FOLIAR APPLICATION OF ZINC, IRON AND BORON ON LEAF NUTRIENT STATUS OF SAPOTA
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 1
Abstract
The field experiment was conducted to know the response of soil and foliar application of zinc, iron and boron on leaf nutrient status of sapota cv. kalipatti under HDP system at Kittur Rani Chennamma College of Horticulture, Arabhavi during the year 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 shown significant increase of macro nutrients like nitrogen (1.75%), phosphorous (0.36 %), potassium (3.06 %) and optimum micronutrient content of zinc (17.60 ppm), iron (162.56 ppm) and boron (43.00ppm) was recorded in the leaf. By the above treatment high macro nutrients content, optimum zinc, iron and boron resulted in high yield and quality of fruits.
