Abstract
A field trial was conducted to study the effect of variable level of N along with recommended dose of P and K through fertigation on growth, yield and quality parameters of pomegranate on eleven year old pomegranate trees cv. Kandhari Kabuli under mid hill conditions of HP. Treatment consisted of five levels of Nitrogen fertilizer 0%, 25%, 50%, 75% and 100% along with 100% recommended dose of P and K through fertigation and conventional method of fertilizer application (with recommended dose of NPK) kept as control. Fertigation treatments had a promising effect over conventional method and treatment of 75% RD of N and RD of P and K through fertigation proved significant over other fertigation treatments and conventional method. Highest tree growth parameters, fruit set, fruit retention, average fruit weight and yield was recorded highest for 75% RD of N and RD of P and K through fertigation. Physico-chemical fruit characteristics viz. highest TSS, lower acidity, highest TSS acid ratio, highest sugars and ascorbic acid content (Vit. C) was also recorded for 75% RD of N and RD of P and K.
