Abstract
The experiment entitled “Effect of severity and time of pruning on growth, yield and quality of custard apple” was carried out at Highway Block, Central Fruit Research Station, Dr. Panjabrao Deshmukh Krishi Vidyapeeth Akola, during year 2016-17 with the objectives to the effect of different severity and time of pruning on growth, yield and quality of custard apple. To find out optimum severity and time of pruning for obtaining maximum yield and quality of custard apple. The experiment was laid out in Factorial Randomized Block Design with two different treatments first are Viz., P1 -15 cm, P2 -30 cm, P3 -45 cm and P4 (control) and second are D1 -15th April, D2 -30th April, D3 -15th May with twelve treatment combination which were replicated three times.
Better growth observations in respect to plant growth, plant volume, mean of plant spread, leaf area, was recorded in 30 cm pruning severity on 30th April. The yield attributing character viz., number of days required for first flowering, number of flower per shoots, higher fruit set, number of seed per fruit was found in associated with 30 cm pruning severity and 30th April on time of pruning. Similarly the maximum number of fruit per plant, fruit yield per plant in kg was recorded in associated with 30 cm pruning severity on 30th April. The better fruit quality in respect of fruit weight, fruit size (length and diameter), total soliable solids, titrable acidity and total sugars was observed in associated with 30 cm pruning severity on 30th April. The effect of interaction between effect of severity and time of pruning on steam diameter, seed weight, splitting fruit and stoning fruit percentages was found non-significant.
Description
In the present investigation entitled “Effect of severity and time of pruning on growth, yield and quality of custard apple” was studied. Custard apple tree is due to heavy load of fruits to maintain to canopy management to applied some pruning treatments to high and most of the production of Annona crops. Different pruning treatments on different dates on effect of growth, yield and quality of that fruit crops .In Custard apple Pruning is important tool to custard apple plantation management as it allows the producer to restrain the exuberant vegetative growth of custard apple to manageable size and forms which is important to control production management and harvest costs, synchronize vegetative growth for more efficient management and sales season. In new shoots maximum number of fruits and fruit weight have more than control tree. Pruning in custard apple is one of the most important practice influencing the vigour, productivity and quality of fruits. Pruning improves not only the fruit quality but it also required at early stage to build up a strong framework in order to increased fruit bearing area of tree become weak and both fruit size and quality impaired.
