“…The efficient utilization of the precipitation is achieved through reducing evaporation and increasing transpiration. That is why a major concern for scientists is the loss of significant amounts of soil water in dryland areas as a result of evaporation (Cooper et al 1987, Perry 1987.…”

Field studies using wheat straw mulching effects on soil water storage and maize development were conducted in China. The studies contained four treatments during three years (2014–2016): CK (no straw and no nitrogen); N (no straw mulching with 172 kg N/ha); HS + N (half straw mulching at the rate of 2500 kg/ha with 172 kg N/ha), and FS + N (full straw mulching at the rate of 5000 kg/ha with 172 kg N/ha). The FS + N treatment significantly increased soil water storage in a drought period during crop growth stages and promoted plant growth along with increased evapotranspiration. The FS + N treatment increased the soil water storage (26.5, 19.9 and 11.1 mm), grain yield (28.7, 6.93 and 2.4%), and water use efficiency (26.6, 6.64 and 2.40%) compared to CK, N and HS + N, respectively. In conclusion, compared to N, HS + N or FS + N increased the biomass (11 and 19%) and water use efficiency (4 and 5%), respectively, and are considered beneficial in Guanzhong, China. Mulching levels were superior to N and compensated the wheat nitrogen requirements. Thus, further studies with minimum fertilizer nitrogen for an environmentally friendly and effective approach are recommended in semiarid regions of China.

“…One is increase of transpiration (T) from a canopy, which can reduces moisture lost daily (Esc) by humidifying the crop canopy [72,73]. Soil evaporation is also affected by the shading of the soil surface by a crop canopy [74]. Higher water use efficiencies of maize reduced (Esc) and a concurrent increase in transpiration (T), due to nitrogen application which was associated with a larger crop leaf canopy [75].…”

Modern cropping is based on relatively high plant density. The improved grain yield per unit area of modern maize (Zea mays L.) hybrids is due to the increased optimum plant population rather than the improved grain yield per plant. High plant density has been widely used to enhance grain yield in maize. Subsequently we review the effect of planting density on physiology, phenology, morphology, nitrogen use efficiency, water use efficiency grain yield information in maize crop. At higher plant populations reduced grain yield also results from the increased pollento-silking interval and the following barrenness. However, it may lead to higher risk lodging hence causing significant yield loss of the crop. Future insights are morphological and physiological basis controlling barren and stalk lodging resistance. How root traits, and anatomy of sheath and stem of maize plants correspond to high plant population and a further study on the physiological and biological basis of organ development that may govern the mechanisms of high plant density would be essential for future research.

“…At these sites, lower 12 early growth of barley with no-tillage resulted in a 53% reduction in grain yield, compared to 13 conventional tillage. This unfavourable crop response to no-tillage was due to a lower crop water use, 14 mainly starting with the stem elongation stage (20% lower than the tilled treatments), and a larger 15 proportion of total water use lost as evaporation (69% compared to 50% of tilled treatments). Values 16 of water use efficiency for grain production (0.7-17.0 kg ha -¹ mm -¹) and transpiration efficiency (7.4-17 23.8 kg ha -¹ mm -¹) were within the ranges reported for cereal crops in Mediterranean environments.…”

“…Conventional tillage using a 14 mouldboard plow as the primary tillage implement followed by repeated shallow tillage is the 15 standard method for controlling weeds during the fallow year. This practice, however, promotes 16 incorporation of surface crop residue, which, in turn, may result in increased soil water losses by 17 evaporation (Aase and Siddoway, 1982) and affect the wind erosion potential of the soil by 18 influencing soil aggregation (Smika, 1990).…”
