Studies On Different Planting System Cum High Density Planting In Litchi Cv. Bombai For Plant Vigour, Fruit Yield And Quality Under New Alluvial Zone Of West Bengal

Abstract

A field experiment was carried out at Horticultural Research Station, Mondouri, BCKV, West Bengal during the year
2014 to 2017 to study the effect of different planting system cum high density planting in litchi cv. Bombai for plant
physico-chemical properties under new alluvial zone of West Bengal. The experiment was laid out in RBD consisting of five treatments viz. Square system, Cluster planting, Paired row, Single hedge row and Double hedge row system with four replications on 12 years old healthy plants. Different planting system cum high density planting significantly
influenced the plant characters of litchi. Among the physical characters, maximum plant height (5.95 m) was recorded
from double hedge row planting followed by single hedge row while the spread of plant and trunk girth was found
maximum in square system. Chlorophyll content of leaf (10.43 mg g-1), number of fruit set per panicle and fruit
retention per panicle was found maximum in square system of planting. The maximum yield (12.87 t/ha) was recorded in double hedge row system of planting while the minimum (9.01 t/ha) from square system. The total soluble solids (17.08 0brix), total sugar content, ascorbic acid and anthocyanin content (35.51 mg/100g) of fruits was found maximum in square system of planting while the minimum in double hedge row system. Finally, it can be concluded that double hedge row planting system was effective in obtaining maximum yield per hectare, while square system of planting was effective in improving the physico-chemical properties of fruits.
