    Energy scenario, carbon efficiency, nitrogen and phosphorus dynamics of pearlmillet-mustard system under diverse nutrient and tillage management practices
    (Academic Journals, 2013) Parihar, C.M.; Bhakar, R.N.; Rana, K.S.; Jat, M.L.; Singh, A.K.; Jat, S.L.; Parihar, M.D.; Sharma, S.
    Under limited moisture conditions integrated nutrient management and conservation agriculture (CA) practices plays a vital role. Information on effect of integrated nutrient management (INM) with CA practices in pearlmillet (Pennisetum glaucum) ?mustard (Brassica juncea) system is lacking. The present experiment was conducted during 2005-06 and 2006-07 in rainy and winter seasons, at IARI, New Delhi, India to investigate the effect of INM and tillage on pearlmillet -mustard system under limited irrigation. Ridge and furrow (RF) sowing produced significantly higher carbon efficiency (CE), energy output, net returns and economic yield (3768 kg ha-1) of pearlmillet-mustard sequence. The application of 30 kg N + 30 kg P2O5 + FYM at 6 t/ha to pearlmillet produced significantly higher yield attributes, economic yield (3982 kg ha-1), energy output (194023 MJ ha-1) of the system and CE and net return (189.41 and 315.8 US$ ha-1) of pearlmillet and mustard individually over control, 30 kg N + 20 kg P2O5/ha and sole application of FYM at 6 t/ha. Direct application of 60 kg N + 40 kg P2O5/ha to mustard produced significantly higher yield attributes, economic yield (3692 kg ha-1), energy output (182097 MJ), net return (296.73 US$ ha-1) and CE (10.80 and 11.51 during both the years), over control and 30 kg N + 20 kg P2O5/ha. The application of INM with ridge furrow sowing increased available N and P contents in the soil. Whereas, the consumptive use, moisture use rates and moisture use efficiency were the highest under ridge furrow sowing of pearlmillet-mustard system.

    Carbon footprint and economic sustainability of pearl millet-mustard system under different tillage and nutrient management practices in moisture stress conditions
    (Academic Journals, 2012) Parihar, C.M.; Rana, K.S.; Jat, M.L.; Jat, S.L.; Parihar, M.D.; Kantwa, S.R.; Singh, D.K.; Sharma, S.
    Pearlmillet (Pennisetum glaucum L.) ? mustard (Brassica juncea L.) is an important cropping system of limited water and marginal land areas grown under improper crop establishment and imbalanced fertilization. Conservation tillage with integrated nutrient management (INM) has potential to improve productivity, maintain soil health and economic sustainability. In present study the response of different tillage and INM on yield, production efficiency, carbon sustainability index (CSI) and economics of pearlmillet and mustard grown during 2005-2006 and 2006-2007 at IARI, New Delhi(India) was evaluated. During all the season?s ridge-furrow sowing resulted considerable improvement in growth and yield of pearlmillet and mustard. Pearlmillet and mustard produced higher yield (2.62 and 1.21 t ha-1), pearlmillet equivalent yield (PEY) (6.52 t ha-1) and production efficiency (31.04 kg ha-1 day-1) when sown in ridge-furrow. Application of 30 kg N and 20 kg P2O5ha-1 along with FYM @ 6 t ha-1 recorded higher yield (2.75 and 1.31 t ha-1) of pearlmillet and mustard, respectively as their residual effect. However, in mustard application of 60 kg N and 40 kg P2O5 ha-1 resulted highest yield (1.30 t ha-1), PEY (6.66 t ha-1) and production efficiency (31.74 kg ha-1 day-1). Net returns and CSI were highest (US $572.4 & 21.92 and 603.4 & 20.02 ha-1) in ridge and furrow and preceding application of 30 kg N and 20 kg P2O5 ha-1 along with FYM @ 6 t ha-1, respectively. In mustard CSI was highest in control (21.84) and net returns (US $ 571.7 ha-1) were highest with highest nutrient level. This study indicates that pearlmillet and mustard can be grown under ridge furrow sowing with INM for sustaining soil health and higher farm profitability.
