Effect of fertigation and micronutrients spray on chlorophyll content of Early Bhagwa pomegranate under semi-arid conditions of Rajasthan

A field experiment was conducted during 2015–17 at research farm of Rajasthan Agricultural Research Institute, Durgapura, Jaipur, Rajasthan in split plot design. The experiment consisted of 12 treatment combinations with three doses of fertigation [100, 75 and 50% of recommended dose of fertilizers (RDF)] and four micronutrient sprays (M₁ to M₄). The pooled data showed that treatment F₃ exhibited maximum total chlorophyll content at vegetative, flowering and harvesting stages of 1.37, 1.30 and 1.16 mg respectively whereas the minimum values (0.87, 0.80 and 0.70 mg respectively) were recorded under application of treatment F₁. The micronutrient treatment M₄ had the maximum total chlorophyll content (1.19, 1.11 and 1.01 mg) at all stages of growth viz vegetative, flowering and harvesting respectively while treatment M₁ showed the minimum value of 1.02, 0.95 and 0.84 mg at three growth stages respectively.
