Abstract
The present investigation entitled “Effect of different pruning intensities on growth and
yield of mustard varieties under Neem (Azadirachta indica) based agroforestry system” was
carried out at the experimental field of the department of forestry, CCS Haryana Agricultural
University, Hisar from October 2021 to April 2022. The performance of three mustard varieties (RH
30, RH 749 and RH 725) grown as sole cropping and intercropping with different pruning intensities of
neem (Azadirachta indica) were noted to ascertain the effect of environment on growth, yield
attributes, yield and oil content. Various growth, biochemical and yield attributing characteristics of
different mustard varieties were observed significantly higher in sole mustard crop (devoid of tree) than
under neem plantation except for days to 50% flowering and maturity. Among the various varieties,
RH 725 was recorded as the best performing variety in all the treatments revealing its high potential in
both sole cropping and agroforestry. Mean yield reduction over control in different environment was
38.54 %, 57.48 %, 66.95% and 76.12 % in 75 %, 50%, 25% pruning intensity and no pruning
respectively. The B:C ratio under sole cropping was 1.70, 2.06 and 2.19 for variety RH 30, RH 749 and
RH 749 respectively while it was 1.12, 1.22 and 1.32 for 75% pruning intensity of neem. In 50%, 25%
pruning and no pruning B:C ratio comes less than 1.
