Effect of intercropping systems on phenology and yield of pigeonpea (Cajanus cajan L.), pearlmillet (Pennisetum glaucum L.) and greengram (Vigna radiata) under western Haryana condition

Abstract

The investigation entitled "Response of nitrogen application in wheat succeeding pigeonpea
intercropped with pearlmillet and greengram" was carried out at the research farm of Chaudhary
Charan Singh Haryana Agricultural University, Hisar during kharif and rabi seasons of 2011-12 and
2012-13. Wheat crop was taken during rabi seasons. It comprised of 12 treatments in kharif and 3
treatments in rabi and the set of treatments was replicated thrice in randomized block design in
kharif and split-plot in rabi season. Different intercropping systems failed to produce significant
variation in days taken to emergence, 50% flowering, 50% pod formation and physiological maturity
in pigeonpea, pearlmillet and greengram. The phenology viz. days taken to emergence, 50% heading
and physiological maturity were not influenced significantly during both years in pearlmillet and
days taken to emergence, 50% flowering, 50% pod formation and physiological maturity were not
influenced significantly by different intercropping systems in greengram. Whereas, grain, straw
and biological yield were the highest in sole crop i.e. pigeonpea (1983 and 2059, 2059 and 5947 and
7777 and 8006 kg ha–1) respectively, pearlmillet (2122 and 2218, 5999 and 6200 and 8121 and 8418 kg
ha–1) respectively, and greengram (1319 and 1402, 3925 and 4175 and 5244 and 5576 kg ha–1)
respectively during 2011 and 2012 crop seasons.
