Abstract
The present investigation entitled âEffect of Varying Pruning Intensities on Fruit Sugar Composition in Guava cv. Lucknow-49âwas carried out during the year 2023-2025 at Govind Nagar Farm, Department of Fruit Science, College of Horticulture & Forestry, ANDUA&T, Ayodhya, Uttar Pradesh, India. The treatments comprised the application of various pruning times and intensities respectively. This study was conducted to analyze the sugar content in guava cv. Lucknow-49. It was laid out in a factorial randomized block design with 13 treatments and 3 replications including control,T1 (Control- No Pruning), T2 (Ti1 P1- 2nd week of April + Pruning of 25 % of shoot length from the tip), T3 (Ti1 P2 -2nd week of April + Pruning of 50 % of shoot length from the tip), T4 (Ti1 P3- 2nd week of April + Pruning of 75 % of shoot length from the tip), T5 (Ti2 P1- 4th week of April + Pruning of 25 % of shoot length from the tip), T6 (Ti2 P2- 4th week of April + Pruning of 50 % of shoot length from the tip), T7 (Ti2 P3- 4th week of April + Pruning of 75 % of shoot length from the tip), T8 (Ti3 P1- 2nd week of May + Pruning of 25 % of shoot length from the tip), T9 (Ti3 P2- 2nd week of May + Pruning of 50 % of shoot length from the tip), T10 (Ti3 P3- 2nd week of May + Pruning of 75 % of shoot length from the tip), T11 (Ti4 P1- 4th week of May + Pruning of 25 % of shoot length from the tip), T12 (Ti4 P2- 4th week of May + Pruning of 50 % of shoot length from the tip) and T13 (Ti4 P3- 4th week of May + Pruning of 75 % of shoot length from the tip) was used for this study. The results revealed that the treatment T9 (Ti3 P2- 2nd week of May + Pruning of 50% of shoot length from the tip) out performed the rest with maximum reducing sugars (4.38 %), non-reducing sugar (3.49 %) and total sugars (7.88 %) with respect to other treatments. Thus, the treatment combination T9 is recommended for application to Guava trees to obtain good sugar contents
