Wheat productivity is determined by better cultivars combined with efficient production
methods. The most essential component in fulfilling a variety's production potential is its
suitability to a certain agro-climate and crop production practices, particularly nitrogen and
irrigation application. The lower dose of nitrogen results in poor yield while higher dose of
nitrogen causes environmental pollution and increases cultivation cost. Therefore, nitrogen
should be applied in sufficient quantities through organic and inorganic sources is essential.
Nitrogen loss and NO3-N contamination of surface and subsurface water can be resulted from
flood irrigation with traditional flat planting and excessive nitrogen application (Akele; 2019).
Alternate furrow irrigation (AFI) is a water-saving technique that is both affordable and simple
to deploy. When compared to traditional furrow irrigation, AFI can reduce the irrigation water
use by 40 per cent without reducing yield, resulting in increased water use efficiency (Cao et
al. 2010).
Methodology
Field experiment was conducted during rabi season of 2021-22 at Agronomy Research Farm
of the C.C.S. Haryana Agricultural University, Hisar, Haryana, India. The soil of the
experimental site was sandy loam in texture, slightly alkaline in reaction, low in organic carbon
and available nitrogen, medium in available phosphorus and high in available potassium. The
experiment was carried out in split plot design with sixteen treatment combinations replicated
thrice. The four varieties (WH 1105, HD 3086, HD 2967 and WH 1184) were assisted in main
plot and nitrogen sources viz. control, 100% RDN through urea, 50% RDN through urea + 50%
RDN through VC and 50% RDN through urea + 25% RDN through VC + 25% RDN through
FYM in sub plots. The pre-sowing irrigation was applied through canal water and the
subsequent two irrigations were applied in alternate furrow at CRI and flowering stage through
an open channel using parshall flume. Furrows subjected to irrigation were open-ended;
however, water does not exceed the edge of the plot, whereas other furrows not subjected to
Resilience through land and water management interventions, water management and governance
