Description The field investigation entitled, “Nutrient management in pearl millet based intercropping
systems under rainfed situations” was conducted at CCS HAU, Krishi Vigyan Kendra farm,
Mahendergarh during Kharif 2011. The experiment comprised of 13 treatment viz., pearl millet
role with recommended dose of nitrogen, pearl millet + cluster bean and pearl millet + mung bean
intercropping each with 100 per cent nitrogen to main crop (M100) and 100 per cent N to intercrop
(I100), M100 I0, M75 I100, M75 I0, M50 I100 and M0 I0 nitrogen levels. The experiment was conducted
in randomized block design with three replications. Based on the research investigation it was
found that phonological events from emergence to physiological maturity as well as the plant
population of the pearl millet at harvest were not influenced significantly by both cluster bean and
mung bean intercrops composed to sole pearl millet. Both the intercrops with 100 per cent
recommended dose of nitrogen gave statistically comparable values of plant height, total number
of tillers/m row length, dry matter accumulation plant-1, effective tillers per m row length, ear head
length, ear girth and test weight of pearl millet as compared to sole pearl millet crop with
recommended dose of nitrogen. Cluster bean intercropping in pearl millet with 75 to 100 per cent
nitrogen dose to main crop and 100 per cent nitrogen dose to intercrop produced statistically equal
yields to sole pearl millet. The pearl millet equivalent yield from pearl millet+cluster bean
intercropping with 100 per cent nitrogen dose to both the crops were significantly more as
compared to other intercropping treatments as well as sole pearl millet. The NPK content in grain
and stover and nitrogen and potash uptake by pearl millet under sole pearl millet and pearl millet
intercropped with cluster bean/mung bean raised with 100 per cent recommended dose of N were
statistically under pearl millet+mung bean intercropping was significantly less than sole crop of
pearl millet. Highest protein content and protein yield of pearl millet was recorded when it was
intercropped with cluster bean closely followed by mung bean intercropping with 100 per cent
recommended dose of nitrogen and sole pearl millet. Gross returns, net returns and benefit cost
ratio were highest in pearl millet+cluster bean intercropping with 100 per cent recommended dose
of nitrogen in both the component crops.
