Abstract:
The present investigations entitled “Impact of chemical thinning with branch girdling on fruit yield and quality of peach (<em>Prunus persica</em> L. Batsch) cv. Shan-i-Punjab” were conducted in the peach orchard of Department of Horticulture, Khalsa College, Amritsar during the year 2017-18. Ten year old uniform, vigorous and healthy trees were selected for the experiment. The experiment was carried out in Randomized Block Design (RBD) with ten treatments comprising of Urea (0.1% and 0.2%) and NAA (100 ppm and 200 ppm) which replicated thrice. The fruits were analysed for their physico-biochemical parameters in the laboratory of Department of Horticulture, Khalsa College, Amritsar. The results of the present study indicate that the combination of chemical thinning with branch girdling was the most effective treatment in improving yield and quality parameters of peach cv. Shan-i-Punjab. The peach trees that were girdled and sprayed with Urea 0.2 per cent (T<sub>7</sub>) attained maximum fruit retention (62.40%) with fruit set per cent of 81.65 and yield of 78.05 Kg per tree and 17.56 tonnes per hectare. Moreover, the fruit quality was also enhanced with treatment T<sub>7</sub> in terms of TSS (12.53 °Brix), TSS: acid ratio (16.96), total sugars (8.20%), reducing sugars (3.50%) and ascorbic acid (14.50 mg/100g). Even, the above treatment gave excellent coloured fruits with prominent red blush and advanced the maturity of fruits with 68.67 days as compared to control.
