|Abstract:||The present investigation was carried out on 13 year old plants of pomegranate Cv. Ganesh, spaced at 5 x 5 m during Ambia bahar of 1992. It involved eight pruning treatments viz., (1) Control, (2) Round-top-pruning, (3) 20 cm pruning of main stems with no thinning, (4) 20 cm pruning of main stems with thinning, (5) 40 cm pruning of main stems with no thinning, (6) 40 cm pruning of main stems with thinning, (7) 60 cm pruning of main stems with no thinning and (8) 60 cm pruning of main stems with thinning. The findings revealed that shoot length and number of leaves per shoot increased with the pruning intensity. Pruning significantly delayed the bud sprouting, flower appearance and the harvesting. Hermaphrodite flowers were increased and the male flowers decreased by pruning, but the effects were marginal. The number of the fruits per tree was the highest in control followed by 20 cm pruning and the lowest in 60 cm pruning. The total yield (weight of fruits) was the highest in 40 cm pruning of main stems and the lowest in round-top pruning. The number and percentage of better grade fruits (A+B grade) are more in higher severity of pruning, and the higher number and percentage of low grade fruits (E+D grade) were observed in control and less severe pruning. The fruit size, juice content and T.S.S. were better with increasing the severity of pruning. The rind and aril colour were not appreciably influenced by pruning treatments. The rind percentage, aril percentage, acidity and seed softness were not deteriorated due to pruning. The incidence of internal breakdown was lowered as the pruning intensity was increased, it was the highest in control. The difference in the number of cracked fruits, fruits with borer infection, fruits with disease spots and fruits with fruit sucking moth infection were non-significant. The aphid and thrip population on the leaves was not influenced due to various pruning treatments. The net returns per hectare were the highest in 40 cm pruning of main stems. Thus, pruning can be adopted in pomegranate to improve the fruit grade, fruit size and to lower down the incidence of internal break down and sun-scorching.|
