Abstract:
A field experiment was carried out at Garden of Department of Horticulture Kalyanpur, Kanpur, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur-208002 during the tenure of 2020-2021 and 2021-2022 to evaluate the flowering, physical fruit quality and yield through different pruning time, intensity and bagging of fruit in Mrig bahar Guava cv. Lucknow-49. The experiment was conducted in a Randomized block design (Factorial) with three replications. The treatment combination comprise of 3 factors viz.3 pruning time, 2 pruning intensity and 2 bagging levels. Based on the experimental results it can be concluded that result obtained from the present investigation, among different pruning time (15^th June), pruning intensity (50%) and fruit bagging (30 DAFS) was found most effective in improving flowering, physical fruiting characters and yield parameters of guava fruit. The results showed that application of T₃P₂D₂ (15 June + Pruning of 50% of the annual growth + Bagging at 30 DAFS) has resulted in the maximum fruit yield (69.69 and 72.18 kg/tree), fruit efficiency (74.96 and 76.97 kg/m³), number of new shoot per prune branch (6.33 and 8.0), length of new shoot (69.29 and 73.32 cm), number of flower per bunch (331.66 and 395.33), fruit set (62.32 and 74.57%), fruit retention (49.59 and 62.66%), number of fruit per tree (169.00 and 177.00), fruit weight (182.26 and 220.53g), volume of fruit (134.86 and 205.26 cc), fruit length (8.14 and 8.45cm), fruit width (8.12 and 8.31cm),during both the year of observation. Pruning of guava trees in the second week of June with 50 percent pruning intensity of annual shoot growth and bagging 30 days after fruit set can be recommended to obtain higher yield with better physical quality fruit and maximum return for guava growers of Central-Western part of the state of Uttar Pradesh.
