Abstract
The present investigation entitled “Effect of different spacing on growth, yield and fruit quality
of lime and lemon” was undertaken at Fruit Research Farm, Department of Fruit Science,
Punjab Agricultural University, Ludhiana during 2020-21. The lime and lemon plants of cv.
Kagzi lime, Limequat and Baramasi lemon budded on Rough lemon rootstock were planted
during September, 2016 at six spacings i.e. 6 x 6 m, 6 x 5 m, 6 x 4 m, 5 x 5 m, 5 x 4 m and 4 x
4 m. Irrespective of cultivars, trees planted at 6 x 6 m distance recorded maximum vegetative
growth in terms of trunk girth, tree spread and canopy volume and minimum was noted in trees
planted at 4 x 4 m distance. Reproductive growth in terms of number of fruits and fruit yield
per tree was also recorded maximum in trees planted at 6 x 6 m distance followed by trees
planted at 6 x 5 m distance. But, productivity was found to be highest in 4 x 4 m planted trees.
Fruits harvested from trees spaced at 6 x 6 m matured earlier and were superior in fruit quality
(fruit size, weight, TSS, Vitamin C) as compared to other spacings. Solar radiation interception
and canopy temperature was also maximum in trees spaced at 6 x 6 m and minimum in 4 x 4 m
planted trees. Canker incidence was recorded maximum in 4 x 4 m planted trees and minimum
in 6 x 6 m planted trees. Among the cultivars, Baramasi lemon gives two crops, whereas Kagzi
lime and Limequat give one crop in a year. Growth, yield and fruit quality (fruit weight, size,
juice percentage, TSS and Vitamin C) of Baramasi lemon was significantly more than Kagzi
lime and Limequat. The radiation interception and canopy temperature was recorded highest in
Limequat followed by Kagzi lime and minimum in Baramasi lemon. Incidence of citrus canker
was recorded only in Kagzi lime during the present investigation.
