“The N and K fertigation (75-30 kg N-K2O ha-1) at 4 days interval has recorded relatively higher plant growth parameters like number of leaves plant-1 (25.5), plant height (208 cm), SPAD Chlorophyll Meter Reading (55.7), leaf area index (3.5) and dry matter (158.1 g m-2) which were on par with N and K at 8 days interval”
