Effect of foliar sprays of micronutrients on nutrients status, yield and fruit quality of kinnow mandarin

Abstract

he study was conducted under arid conditions of north-western Rajasthan during the year 2007-08 at ClAI-1, Bikaner. The experiment was laid out with 15 treatments replicated three times in randomized block design. The trees were maintained with common cultural practices under drip irrigation system. Foliar applications of micronutrients viz. Fe (0.50%, 1M%), Cu (0.25%. 0.50%) and Zn (0.50%, 1.0%) alone and in combinations were done twice (at an interval of one month) in the month of June and July on six years old kinnow trees. The maximum nitrogen, phosphorus, iron, copper and zinc content was obtained in leaves by foliar sprays of micronutrients treatment Fe 0.50%+Zn 0.50%-f-Cu 0.25% under hot arid conditions. The higher fruit yield and quality attributes were also observed under this treatment.
