Effect of N and P fertigation on fruit yield and quality of kinnow

The effects of N and P fertigation on productivity quality kinnow mandarin were investigated in southwestern part Punjab at the Regional Research Station, Abohar Agricultural University, Ludhiana, during 2018–2020. Different combinations recommended dose (RD) P, viz. 100, 75, 50% applied equal splits 5 stages trees (February–October) compared with conventional flood irrigation plus soil fertilization. results showed that resulted higher nutrient uptake, total leaf chlorophyll content, vital physiological processes as to practices. Tree volume under was about 29% than data also revealed a significantly fruit set (20.13%), weight (168.6 g), size (7.68 cm) Fruit yield 33% fertigated over Further, parameters especially terms per cent juice, TSS-acid ratio, ascorbic acid concentration superior trees. In addition, proportion economic grades suggest @75% exhibited growth mandarin, saving 25% usage better grade andhigher kinnow.
