| dc.description.abstract | The present investigation entitled “Studies on canopy management practices in high density planting of guava (Psidium guajava Linn.) cv. Hisar Safeda” was carried out at experimental orchard, Department of Horticulture, CCS Haryana Agricultural University, Hisar during the year 2014-15 and 2015-2016. There were three treatments, i.e. pruning, pinching and spacing. The guava trees were pruned at four different levels, i.e. 20%, 40% and 60% removal of shoot and no pruning (control) was done in the month of April and plants pinched with three pinching numbers, viz. no pinching, one time pinching (first week of August) and two times pinching (first week of August and first week of October) were done on the pruned plants planted at four plant spacing, i.e. 5x2, 5x3, 5x4 and 5x5 m. All the treatments were effective in managing the growth characters, however, pruning at the level of 60% and two times pinching were found most effective in increasing the growth characters, viz. shoot length and stem girth over control, while number of sprouts per shoot was recorded maximum in plants receiving 20% removal of shoot. The growth characters, viz. plants height, plant spread and tree volume was significantly reduced by various pruning and pinching treatments. Yield characters, viz. number of fruits and yield per plant were recorded maximum in control plants with no pruning, however, one time pinching recorded maximum yield per plant during rainy season. However, 60% removal of shoot and two times pinching were found most effective in improving the yield characters in terms of average fruit weight and fruit volume, while 40% removal of shoot and two times pinching were found most effective in improving the number of fruits and yield of guava during winter season. Quality parameters in terms of TSS, acidity, ascorbic acid, total sugars and pectin content were recorded maximum in plants receiving 40% removal of shoot, whereas, plants receiving one time pinching produces best quality of fruits during rainy season, while during winter, plants subjected to two times pinching produces best quality fruits in terms of TSS, acidity, ascorbic acid, total sugars and pectin content. Leaf content, viz. NPK was recorded maximum in leaves taken from plants receiving 60% removal of shoot and two times pinching during both the seasons. In all planting density, the plants grown at 5x5 m proved its superiority for growth, yield and quality characteristics in guava. | en_US |
