Abstract
The aim of this study was to assess the option of intercropping mungbean (MB) in late
season cotton to enhance productivity of the system. Mungbean was intercropped with
cotton under two planting techniques practiced in Punjab for cotton sowing. Treatments
consist of mungbean broadcast in 75 cm spaced drilled cotton rows (IS1), alternative
rows of cotton and mungbean (IS2), two rows of mungbean between cotton rows (IS3)
while in fourth treatment (IS4) two mungbean rows were sown on top of 105 cm wide
double ridge-furrow (beds hereafter). Results showed that mungbean presence
adversely affected the number of opened, total bolls plant-1
, opened boll percentage and
seed cotton yield in all intercropping systems. However in bed intercropping, cotton
produced 21.84 % higher seed cotton yield than sole cotton. Alike, number of pods
plant-1
and number of grains pod-1 of mungbean decreased in intercropping treatments
compared to sole mungbean. On average, mungbean yield was 21.1 % less in
intercropping treatments than sole mungbean. Yield advantage indicated by LER and
ATER values was observed in all intercropping treatments except in IT3 where ATER
suggested disadvantage. Highest LER (1.92) and ATER (1.58) were recorded in IS4.
Aggressivity value indicates that bed structure favoured the cotton growth compared to
mungbean. All intercropping systems showed positive values of system productivity
index and monitory advantage index. This study concludes that productivity of late
season cotton could be better enhanced by sowing two rows of mungbean on top of the
105 cm wide cotton beds.
