    Response of nitrogen application in wheat succeeding pigeon pea intercropped with pearlmillet and greengram
    (CCSHAU, 2015) Barod, Niranjan Kumar; Satish Kumar
    The investigation entitled “Response of nitrogen application in wheat succeeding pigeon pea intercropped with pearlmillet and greengram” was carried out at the research farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar during kharif and rabi season 2011-12 and 2012- 13. It comprised of 12 treatments in kharif and 3 treatments in rabi and the treatments were replicated thrice in randomized block design in kharif and split plot in rabi season. Based on aforesaid investigation it was found that intercropping systems influenced the growth parameters of both main and intercrop. Plant height of pigeon pea was not significantly influenced at early stage i.e. 30 days after sowing but significant differences were recorded at 60,90,120 days after sowing and at harvest. Among different intercropping systems pigeon pea planted at 75 cm with pearlmillet 1:2 produced taller plants. In case of intercrop i.e. pearlmillet and greengram, plant height increased significantly in intercropping systems as compared to sole crop. Pearlmillet was produced taller plant in pigeon pea 75 cm + pearlmillet (1:2) and greengram produced in pigeon pea 75 cm + greengram (1:1). Dry matter accumulation per plant of pigeon pea was influenced by different intercropping systems it was highest when pigeon pea planted at 90 cm with greengram 1:1. Yield attributes viz. number of branches per plant, grain per pod and 1000 grains weight of pigeon pea was not influenced by intercropping systems except number of pods which was maximum in pigeon pea (90 cm) + greengram (1:1). The number of effective tillers and grains per spike was highest in pigeon pea 90 cm + pearlmillet (1:1). In case of greengram, number of pods was maximum recorded when greengram planted one row in pigeon pea at 90 cm. Grain, straw and biological yield was significantly influenced of pigeon pea, pearlmillet and greengram. It was highest recorded in sole crop. Among different intercropping systems tested during kharif season, pigeon pea 75 cm intercropped with two row of greengram was found most suitable. pearlmillet intercropped with pigeon pea irrespective of row spacing with one or two row was found economical than sole pigeon pea / sole pearlmillet but inferior to greengram intercrop. The effect of different intercropping treatments as succeeding wheat nitrogen requirement was not found significant. Application of 100% RDN produce significantly higher grain yield of wheat as compared to 75 % RDN and this treatment was also found superior than 75 % and 125 %RDN in respect of economic. Systems wheat equivalent was found higher when wheat was planted after pigeon pea (75 cm) with two rows of greengram. No interaction between N levels and intercropping systems (kharif) was found significant.
