Effect of exogenous application of micronutrients on growth and yield of Kinnow mandarin under semi-arid zone of Haryana

Abstract

An experiment was conducted during 2014-15 to assess the performance of Kinnow mandarin to soil and foliar mode of micronutrients application. The study comprised of six treatments, viz., T1- FeSO4 42g + MnSO4 21g + ZnSO4 14g, T2- FeSO4 84g + MnSO4 42g + ZnSO4 28g, T3- FeSO4 126g + MnSO4 63g + ZnSO4 42g, T4- FeSO4 168g + MnSO4 84g + ZnSO4 56g, T5- Foliar spray of 0.5% each of FeSO4, MnSO4, ZnSO4 + 1% Urea and T6- Control (No micronutrients). Four treatments (T1 to T4) were applied through soil in four equal splits. Foliar spray was also performed four times during soil application of micronutrients. All micronutrients treated plants produced higher magnitude of growth and fruit yield over control. However, foliar application of micronutrients produced significantly higher number of fruits, fruit weight, juice content, and fruit yield (28.9 t ha-1) compared to other treatments.
