Abstract:
To investigate the effect of NAA and Nutrient levels on fruit retention, yield attributes of Pomegranate (Punica granatum L.). The experiment was laid out on 7-year old Bhagwa plantation at a spacing of 12 x 8 ft. at JNKVV, Krishi Vigyan Kendra, Chhindwara (M.P.) India during (2019-2020 and 2020-2021) out. The experiment consisted of eighteen treatments combination include three level of recommended dose of fertilizers as soil application (100%, 75% and 125% RDF) with three level of NAA (0ppm, 10ppm and 20ppm) and drip fertigation (15 days and 30 days interval) with three replications under factorial randomized block design. The present investigation revealed that maximum fruit retention (%), TSS (⁰Brix), Total sugar (%), Reducing sugar (%), no. of fruits/plant and fruit yield kg/plant was recorded under T₁₃ (100% RDF + NAA 20 ppm + fertigation 15 days interval) followed by T₇ (100% RDF + NAA 10 ppm + fertigation 15 days interval) and the minimum fruit retention %, TSS, Total sugar, Reducing sugar, no. of fruits/plant and fruit yield kg/plant was recorded in treatment T₄ (75% RDF + 0ppm NAA + fertigation 30 days) during both the years and in pooled analysis. Chemical fertilizer (N, P, K) and plant growth hormone (NAA) significantly effected on fruit retention and quality of pomegranate fruits.
