Apparent crop water productivity, energy use efficiency and energy productivity was higher under irrigation at 3 days after disappearance of ponded water while net returns and benefit:cost ratio (B:C) was higher under irrigation at 2 days after disappearance of ponded water. Thus, basmati rice ...
ZTW sown with Happy seeder under full residue retention, achieved maximum net return 43.16–57.08 × 103 ₹ ha−1) and B-C ratio (1.52 to 1.70) over CTW without residue. Therefore, rice residue needs to be managed by planting wheat using appropriate machinery under ZT for ...
The “SS” was sum of squares and the “SS%” was the ratio of SS to total SS [the summation of SS(cultivars), SS(water condition) and SS(CWI)]. Download : Download high-res image (295KB) Download : Download full-size image Fig. 1. The Cd concentration in rice grain of ...
Researchers expressed concerns on sustainability of rice cultivation associated with high energy demand, deterioration of the groundwater table and escalating cost of groundwater pumping from deeper depth as a result of puddling and ponding practices (Humphreys et al.2010; Chauhan et al.2012). It is...
rice populations published from 2001 to 2019. Yield and yield-related traits including grain weight, heading date, plant height, tiller number as well as root architecture-related traits including root dry weight, root length, root number, root thickness, the ratio of deep rooting and plant ...
Fo, Fm and Fv/Fm ratio were monitored after water-stress treatment of etiolated rice seedlings for 72 h with 40 mM and 50 mM PEG, in the presence of light (100 μmol photons m−2s−1). Seedlings were kept for 20 min in darkness (see Materials and Methods) before the initial ...
(6.6 and 6.7 t ha–1)was recorded in DDSR using Chenab Basmati-2016 under AWD irrigation threshold that attributed to high tiller density and LAI.The economic analysis showed DDSR as more beneficial rice establishment method than TPR with a high benefit-cost ratio(BCR)when the crop was ...
A research study was carried out to determine the electrical conductivity (EC), residual sodium carbonate (RSC), sodium adsorption ratio (SAR), p H and metals in metal-polluted irrigation water from a nullah and those in soils over a period of time, and the effect of metals on rice yield...
[Crude protein (CP), and ether extract (EE)] and productivity [green fodder yield (GFY), dry matter yield, CP yield, EE yield and ash yield) and profitability (gross returns, net returns, benefit鈥揷ost ratio) significantly decreased with the increase in irrigation water RSC from 5 to 7...
(NI),economic water use efficiency (EWUE) and benefit-cost ratio (BCR) analysis, the production benefit of the in-furrow planting method was higher than the production cost compared with the basin method even in the first year of the planting; whereas, it was not economically feasible for ...
