“…Irrigation and fertilization not only account for high costs but are also among the most important factors affecting forage crop quantity and quality (Islam, Garcia, & Horadagoda, 2012; Khelil, Rejeb, Henchi, & Destain, 2013). Philipp, Allen, Mitchell, Brown, and Wester (2005) showed that increased irrigation in bluestem forages ( Bothriochloa spp.)…”

This experiment was conducted to evaluate the effects of two irrigation regimes (control and water stress) and two nitrogen (N) levels (0 and 112.5 kg/ha) on forage yield and silage quality in millet. Bastan (Setaria italica (L.) P. Beauv) and Pishahang (Panicum miliaceum) were sown at two different dates during 2015 and 2016. Both cultivars exhibited reduced dry‐matter (DM) yields (45% and 51% in Bastan and Pishahang respectively) due to drought stress. Proline and phenolic contents increased as a result of drought and were significantly and negatively correlated with DM yield and digestibility. Moreover, Pishahang had a reduced acid detergent fibre (ADF) content but improved leaf/stem ratio, digestible dry matter (DDM), relative feed value (RFV), net energy for lactation (NEL), digestibility and silage quality as a result of drought stress, while no significant effects on these traits were observed in Bastan. Silage quality was greatly cultivar‐dependent. Both cultivars had higher levels of DDM, RFV and NEL at early sowing dates. Nitrogen supply had greater positive effects on increasing ash, crude protein (CP) content and DM yield under normal irrigation than under water‐stress conditions. In summary, given the importance of the energy received per unit of forage from an animal husbandry viewpoint and the significance of DM yield per unit area from an agricultural viewpoint, the obtained results might help farmers in choosing not only the best sowing dates but also proper irrigation and N management practices to achieve their quantitative and qualitative objectives in forage production.

“…Irrigation and fertilization are the most important cultivation practice factors for plant production (Khelil et al, 2013). Use of excessive water and nitrogen can result in environmental pollution (Ferrer et al, 1997), extra cost and negative effects on soil (Khelil et al, 2013) but inadequate use of these dramatically decrease grain yield and quality, too. Available irrigation water is limited and costly so that reason urgent precautions should be taken in to consideration for water preservation without any yield penalty in plant production Oktem (2008).…”

Irrigation and fertilization are the most important cultivation practice factors for plant production (Khelil et al, 2013).

The aim of the study was to investigate effects of different irrigation levels and nitrogen doses to chemical composition, in vitro gas and methane production of maize kernel for animal feeding. Three different nitrogen doses such as 100, 200 and 300 kg ha-1 N and irrigation levels such as 50%, 75% and 100% of depleted water were applied. The study was carried out under split plot for randomized complete block experimental design with three replicates during 2013-2014 seasons and irrigation levels were allocated in to main plots while nitrogen doses in to sub plots. The two-year results of the study showed that crude protein, crude ash and crude oil ratios and gas and methane production, metabolic energy (ME) and organic matter digestibility (OMD) were positively affected by increased level of water levels and nitrogen doses while acid detergent fiber (ADF) and neutral detergent fiber (NDF) and dry matter contents were negatively affected. It is clear that increased level of water and nitrogen positively contributed to quality of maize kernel for animal production but more researches are needed to explain how increased level of water and nitrogen result in higher level of gas and methane production.

“…Current global warming and climate change (World Water Assessment Program, 2009) restrict the water resources and thus enforce the growers to perform such optimizations. Increased water and nitrogen treatments not only increase the production costs, but also result in serious environmental pollution over the agricultural fields (Ferrer et al, 1997) and negative influenceson soil structure (Khelil et al, 2013). Nitrogenous fertilization and synergic effect of water improve nutrient uptake and yields (Kim et al, 2008).…”

“…Thus, maize is the most significant silage crop both worldwide and in Turkey (McDonald et al, 1991;Meeske et al, 1993). Irrigation and fertilizations are the greatest cost items in crop culture and they are also among the most significant factors effecting the yield and quality in pasture and forage crops (Islam et al, 2012;Khelil et al, 2013). Water and nitrogen are the critical issue in maize culture, especially for yield and quality of maize.…”

The study was conducted to investigate the effects of different irrigation levels and nitrogen doses on yield, yield parameters, silage characteristics, digestibility, gas and methane production of corn silage. Three different irrigation levels (50%, 75% and 100% of depleted water) and 3 different nitrogen doses (100, 200 and 300 kg ha-1 N) were applied to corn silage. Experiments were implemented in split-split plots design with three replications during the growing seasons of 2013-2014. Plants were harvested at milk-dough stage and yield and morphologic characteristics were determined. Then, harvested plants were silaged and chemical characteristics were investigated. Irrigation level x nitrogen dose interaction was not found to be significant. Increasing nitrogen doses increased plant height, plant diameter, green herbage yield, crude protein, metabolic energy, gas production and organic matter digestibility and decreased pH levels, ADF and NDF ratios. Increased irrigation levels positively affected green herbage yield, plant height, plant diameter and increased ADF and NDF ratios. Gas production, metabolic energy and organic matter digestibility decreased with increasing irrigation levels. Increasing irrigation levels improved corn yields, but reduced the quality. On the other hand, increasing nitrogen doses had positive contributions both to yield and quality characteristics.
