Abstract:
The present study was carried out to evaluate the effect of precision farming on leaf nutrient content of banana cv. Rajapuri (AAB) during 2020-2022. The experiment was laid out in Randomized Complete Block Design with thirteen treatments and three replications. There was a significant difference was observed among treatments tested for leaf nutrients. The results revealed that application of 100 percent RDF through fertigation at weekly intervals along with polythene mulch with foliar spray of micronutrient mixture recorded the highest nitrogen (2.56%), phosphorous (0.26%), potassium (3.13%), calcium (1.13%) magnesium (0.78%), zinc (37.61 ppm) and manganese content (113.08 ppm) in banana leaf which was on par with application 75 percent RDF through fertigation at weekly intervals along with polythene mulch and foliar spray of micronutrients. All the treatments with mulch were found significantly superior over the non-mulched treatments at corresponding fertigation levels.
