Deficit irrigation effects on adjunct and all‐malt barley yield and quality
نویسندگان
چکیده
Semi-arid regions are reliant on irrigation to produce large-yielding and high-quality malt barley (Hordeum vulgare, L.). Drought in the western United States is of concern as surface ground water reductions occurring that affect availability. Implementing a seasonal deficit compared evapotranspiration (ET) potential strategy reduce usage if yield quality can be maintained. Research was conducted Aberdeen, ID effects yield, grain quality, characteristics. Five genotypes were selected represent those used for large-scale adjunct brewing targeted at all-malt craft industry. Irrigation managed three rates (100%, 75%, 50%) estimated crop (ETc) using sprinkler irrigation. Total aboveground dry matter (TDM) not affected by until soft dough (Feekes 11.2; F11.2). Yield similar within genotype with reduction from 100% ETc 75% ETc. Averaged across genotypes, yields 6936 kg ha−1 6297 At ETc, protein remained just below target (130 g kg−1) four five while all exceeded (120 kg−1). Reduced decreased extract increased diastatic power (DP), where β-glucan either did differ or increased. Deficit promising, particularly brewing; however, expected changes malting must understood selection, altered fertilizer management, and/or criteria may needed implementation This article protected copyright.

Effect of deficit irrigation on crop growth, yield and quality of onion in subsurface drip irrigation
Indiahas the largest area under onion (Allium cepa) crop but its average productivity (14.21 t ha-1) is considerably lower than the world’s average of 19.4 t ha-1. Besides low productivity, irrigation efficiencies are also very low i.e. 30-35% in India. Managing onion crop with less than adequate irrigation water availability is a challenge in several parts of the country. Options of i) deficit...

This experiment was conducted to evaluate the effect of deficit irrigation on seed yield and its components of sunflower hybrids, and also identify tolerant hybrids. Twelve sunflower hybrids; Farrokh, Shams, Ghasem, Barzegar, G5 ×43, G6×43, Hysun25, Hysun36, Azargol, Sumbro, Euroflor and Sirena were evaluated under three irrigation treatments; normal irrigation (60 mm), mild drought stress (1...
