NUTRITION MANAGEMENT IN CITRUS: EFFECT OF MULTINUTRIENTS FOLIAR FEEDING ON THE YIELD OF KINNOW AT DIFFERENT LOCATIONS
MUHAMMAD YASEEN1* AND MANZOOR AHMAD2
Abstract
Maintaining health of citrus plants by nutrition management demands to deal citrus as a tree plant that has growth in shifts. There is a need to chalk out nutrition programme by keeping in mind growth as well as phonological cycles of the plant because every shift of growth in association with phonological and growth cycles needs special attention to decide fertilization programme. There is a need to develop well established production technology to increase the production of this crop substantially by using non-conventional approaches alone or in combination with conventional approaches. The use of multi-nutrient plant growth regulator formulation amended with appetizer is a new and innovative approach to develop a cost effective foliar spray “Micro Power” for improving citrus yield. Results from two demonstration trials revealed that NPK fertilizers (calculated on the basis of age and foliage on fruit trees rather than on the basis of area) application on drip line in combination with foliar spray was helpful to improve production of quality citrus (kinnow) fruits up to 63%. Moreover, this strategic management of nutrition was also helpful to identify appropriate time and growth stage for the application of fertilizer mix.
