Nutrient and weed management practices effect on growth, nodulation, yield, economics and energetics of Chickpea (Cicer arietinum L.)
Author(s): Sahaja Deva and SS Kolhe
Abstract: Field experiment was carried out at Research Farm, Indira Gandhi Krishi Viswavidyalaya, Raipur (Chhattisgarh) during Rabi seasons of 2013-14 and 2014-15 to study the effect of nutrient management and weed management practices on yield and nutrient status. The highest crop stand was under 100% RDF i.e. 17.35 and 18.1 during 2013-14 and 2014-15, respectively with mean of 17.73 and in untreated control i.e. 18.48 and 18.81 during 2013-14 and 2014-15, respectively with mean of 18.65.The maximum number of nodules and nodule dry weight were obtained under 100% RDF. Pre-emergence application of metribuzin 0.4 kg ha-1 + oxyfluorfen 0.3 kg ha-1produced the maximum number of nodules and nodule dry weight. Application of 125% RDF gave the maximum net returns (http://t3.gstatic.com/images?q=tbn:ANd9GcQgWzYoOCcAo6BD4zm8Fe5gPOV_F4k6kGvcj3lXPUbgDd32nn10BQ44282ha-1 and http://t3.gstatic.com/images?q=tbn:ANd9GcQgWzYoOCcAo6BD4zm8Fe5gPOV_F4k6kGvcj3lXPUbgDd32nn10BQ58688 ha-1during 2013-14 and 2014-15, respectively with mean of http://t3.gstatic.com/images?q=tbn:ANd9GcQgWzYoOCcAo6BD4zm8Fe5gPOV_F4k6kGvcj3lXPUbgDd32nn10BQ51485ha-1) and benefit: cost ratio (3.03 and 3.45 during 2013-14 and 2014-15, respectively with mean of 3.24). Pre-emergence application of metribuzin 0.4 kg ha-1+ oxyfluorfen 0.3 kg ha-1 gave the maximum net returns (http://t3.gstatic.com/images?q=tbn:ANd9GcQgWzYoOCcAo6BD4zm8Fe5gPOV_F4k6kGvcj3lXPUbgDd32nn10BQ 61176 ha-1 and http://t3.gstatic.com/images?q=tbn:ANd9GcQgWzYoOCcAo6BD4zm8Fe5gPOV_F4k6kGvcj3lXPUbgDd32nn10BQ 75130 ha-1 during 2013-14 and 2014-15, respectively with mean of http://t3.gstatic.com/images?q=tbn:ANd9GcQgWzYoOCcAo6BD4zm8Fe5gPOV_F4k6kGvcj3lXPUbgDd32nn10BQ 68153 ha-1) and benefit: cost ratio (3.65and 3.98 during 2013-14 and 2014-15, respectively with mean of 3.82). The maximum energy intensiveness (2.07 and 2.20 during 2013-14 and 2014-15, respectively with mean of 2.13) was under application of 125% RDF. Amongst the weed management practices, the maximum energy intensiveness (2.39 and 2.45 during 2013-14 and 2014-15, respectively with mean of 2.42) was under pre-emergence application of metribuzin 0.4 kg ha-1 + oxyfluorfen 0.3 kg ha-1.
