Performance of component crops in tree-crop farming system under arid region

Abstract

Variations were recorded in growth and yield performances of trees as well as annual crops grown in combination under tree-crop farming. Plant growth and yield of all component crops were higher when grown under conjugation as compared to their sole croppings. Under integrated model, there was 50-53% increase in yield (84.60 to 86.52 q/ha) of ber over its sole cropping (56.32 q/ha). Allelo-chemical study revealed negative response of leaf extract of tree crops on germination and growth parameters of seedlings of annual crops. However, karonda leaf extract exhibited positive response on seedling germination and growth parameters of mustard (germination 93.3% as against 86.6% in control) and also of brinjal (germination 93.3% as against 88.3% in control).
