Lalit" [Thesis, Ph.D.]. Banda University of Agriculture and Technology, Bandahttps://krishikosh.egranth.ac.in/handle/1/5810215161The present investigation entitled "Effect of pruning time and level on fruiting and fruit quality of guava (Psidium guajava L.) cv. Lalit" was conducted at Instructional Farm, Department of Fruit Science, College of Horticulture, Banda University of Agriculture & Technology Banda, (U.P.) during the year 2021-23. The experiment was laid out in RBD (factorial) design with six pruning times and three pruning levels and replicated thrice. Results revealed that the significantly minimum average time taken to bud burst, average time taken to bud sprout, average time taken to flower initiation, average time taken to full bloom, average time taken to end of bloom, average time taken to fruit maturity, average time taken to colour break in fruits were noted in second week of May with 20% pruning during both the years. However, significantly maximum final fruit set were recorded in last week of April with 40% pruning.  The highest average number of fruits per plant, fruit yield per plant (kg), fruit yield ton/ha, fruit weight, fruit volume, pulp weight, pulp and seed ratio, total soluble solid, total sugar, reducing sugar, non-reducing sugar, ascorbic acid, pectin, pH, total soluble solid and acid ratio and were recorded in last week of April with 40% pruning whereas, minimum specific gravity and seed weight were observed in last week of April with 40% pruning.  Therefore, on the basis of results, it can be concluded that guava pruning should be carried out in the last week of April with 40 % pruning intensity followed by pruning in last week of August with 40 % pruning level to obtain maximum fruit set, yield and fruit quality of guava cv. Lalit. The same can be recommended to the farmers and researchers.EnglishThesis
