Abstract
The 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.
