Response of zinc, boron and molybdenum on growth, yield attributes and yield of chickpea (Cicer arietinum L.) under rainfed conditions

摘要

Studies on the effect of zinc (Zn), boron (B) and molybdenum (Mo) on yield attributes and yield of chickpea under rainfed conditions were conducted during the rabi seasons of 2012-13 and 2013-14 at the university farm of M. G. C. G. V. V., Chitrakoot, Satna, M. P., India. Awarodhi variety of chickpea was tested with three levels of each Zn (0, 2.5 and 5.0 kg/ha) and B (0, 1 and 2 kg/ha) and two levels of Mo (0 and 400 g/ha). The highest values of yield attributes viz., plant height, number of branches/plant, number of nodules/plant, nodule dry weight (mg) /plant, number of pods/plant, number of grains/pod and test weight were recorded at Zn @ 5.0 kg/ha, B @ 2.0 kg/ha and Mo @ 400 g/ha. The highest yields of grain and stover were also observed at the above same levels of Zn, B and Mo. The response on yield attributes and yield was statistically significant with the application of Zn @ 5.0 kg/ha, B @ 2.0 kg/ha and Mo @ 400 g/ha over its lower doses. The grain yield was increased by 14.5, 7.2 and 4.8 due to the use of Zn @ 5.0 kg/ha, B @ 2.0 kg/ha and Mo @ 400 g/ha, respectively, over their respective control.
