Wheat, nutrient content, uptake, yield and intercropping systems.Abstract
The investigation was carried out during Kharif and Rabi season of 2011-12 and 2012-13. The effect
of different intercropping treatments on nitrogen requirementof succeeding wheat was significant.
Maximum N content in grains and straw was recorded with 125% RD of N during both the years.The
uptake of N in grain and straw increased significantly with the increasing levels of N during both
the year of study. The maximum total N uptake was recorded with the application of 125% followed
by 100% N ha–1. Wheat produced significantly higher grain yield when planted after pigeonpea (75
cm) + greengram (1:1 or 1:2) treatment as compared to pearlmillet intercropping treatments at the
same row spacing and row ratio. Application of 100 percent RDN being at par with 125 percent
RDN produced significantly higher grain yield of wheat as compared to 75 percent RDN.
