Effect of nitrogen fertigation on growth and yield of pomegranate var. Mridula under low rainfall zone¹

Highest plant height (2.0 m), stem girth (43.5 cm), no. of fruits (45.1) and fruit yield (11.6 kg) per tree were recorded in T7 treatment (50% recommended dose of nitrogen at fortnight intervals) followed by T6 treatment (50% recommended dose of nitrogen at monthly intervals) in which plant height (1.9 m), stem girth (42.6 cm), No. of fruits (42.0) and fruit yield (9.4 kg) were recorded. Plant spread was recorded highest (2.4 m3) in T6 treatment followed by T7 treatment (2.2 m3) when Nitrogen fertilizers were applied through drip Irrigation. 50% recommended dose of nitrogen at fortnight intervals enhanced yield in pomegranate/tree under low rain fall zone. It also saved 50% nitrogen fertilizers cost and labour cost.
