Abstract
Chickpea (Cicer arietinum L.) is the most important nutritive pulse crop which is cultivated throughout the world. A field experiment was conducted in order to study the effect of sulphur on growth and yield of chickpea (Cicer arietinum L.) under rice chickpea cropping system. A commercial chickpea variety DG-89 was used for this study under five treatments T1 = 36-72 kg NP ha־¹ + 0 kg S ha־¹ (Control), T2 = 36-72 kg NP ha־¹ + 20 kg S ha־¹, T3 = 36-72 kg NP ha־¹ + 40 kg S ha־¹, T4 = 36-72 kg NP ha־¹ + 60 kg S ha־¹ and T5 = 36-72 kg NP ha־¹ + 80 kg S ha־¹. The results of the study showed that the application of 36-72 kg NP ha־¹ + 40 kg S ha־¹, resulted maximum plant height, more pods plant-1, higher number of branches plant-1, maximum seed index 1000 grain weight and more grain yield over control. The maximum nitrogen and phosphorous content in chickpea were noted due to S application @ 36-72 kg NP ha-1+ 40 kg S ha-1. It is concluded that for better growth and yield of chickpea sulphur application @ 40 kg S ha-1 should be included in the fertilization program of chickpea along with recommended NP (36-72 kg NP ha-1) under rice chickpea cropping system
鹰嘴豆(Cicer arietinum L.)是世界上最重要的营养豆类作物。为研究水稻鹰嘴豆种植制度下硫对鹰嘴豆生长和产量的影响，进行了田间试验。以商品鹰嘴豆品种DG-89为研究对象，采用5个处理，T1 = 36-72 kg NP ha + 0 kg S ha +对照，T2 = 36-72 kg NP ha + 20 kg S ha + 1, T3 = 36-72 kg NP ha + 40 kg S ha + 1, T4 = 36-72 kg NP ha + 60 kg S + 1, T5 = 36-72 kg NP + 80 kg S + 1。结果表明，施用36 ~ 72 kg NP + 40 kg S，可获得最高株高、最大荚果数、最大分枝数、最大千粒重和最高籽粒产量。鹰嘴豆氮磷含量最高是在36 ~ 72 kg NP hm -1+ 40 kg S hm -1处理下。综上所述，为提高鹰嘴豆的生长和产量，水稻鹰嘴豆种植制度下，鹰嘴豆施肥方案中应施用40 kg S hm -1的硫，同时推荐NP (36-72 kg NP hm -1)
