“…Barley tiller development occurred later for those plants receiving N at irrigation, especially on the 25 kg N jha at seeding plots, and appeared to be initiated only after a minimum of 75 kg Njha had been applied. Barley yield component data are consistent with data published by Schreiber and Stanberry (13) showing significantly more spikes per pl~nt, fewer kernels per spike, and greater kernel weights when N was split equally between planting, internode elongation, and pollination or between planting and pollination than when the total N amount was applied at planting-In Schreiber and Stanberry's study, however, grain yields were increased significantly by splitting N applications on a flood irrigated loamy sand with severe leaching problems.…”

Information on the effectiveness of N fertilizer applied through sprinkler irrigation systems for springsown wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) is limited. Objectives were to determine grain yield and quality responses and N‐use efficiency when N fertilizer was applied at irrigation to wheat and barley grown on a fine‐silty, mixed Typic Haploboroll. Nitrogen fertilizer was applied to sprinkler irrigated ‘Newana’ hard red spring wheat and ‘Shabet’ malting barley at seeding or split between seeding and heading, flowering, or watery kernel growth stages. Treatments included N rates of 0, 50, 100, and 150 kg N/ha at seediig, 75 kg N/ha at seeding plus 25 kg N/ha at heading or flowering, and 50 kg N/ha at seeding plus 50 kg N/ha at heading or 25 kg N/ha at heading and 25 kg N/ha at flowering. Additionally, 25, 50, and 25 kg N/ha were applied to barley at seeding, heading, and flowering, respectively; and 100 and 25 kg N/ha were applied to wheat at seeding and watery kernel stage, respectively. Nitrogen at seeding was broadcast as NH4No3‐, Subsequent N applications were broadcast as NH4NO3, several, hours prior to an irrigation to simulate application through the sprinkler system. Wheat plots contained subplots fertilized with 15NH415NO3 containing 1.31 atom percent 15N to determine the fate and utilization efficiency of applied N. Grain yield increased from 1,100 to 4,850 and from 1,240 to 4,570 kg/ha for wheat and barley, respectively, as N rates were increased from 0 to 150 kg N/ha at seeding. When 100 kg N/ha was split between seeding and at irrigation, wheat yields decreased from 3,890 to 3,540 and 2,975 kg/ha as the amount of N applied at seeding was decreased from 100 to 75 and 50 kg N/ha, respectively. Barley yields averaged 4,130 kg/ha for treatments totaling 100 kg N/ha and were generally not affected by shifting N applications from seeding to at irrigation. Differential response to split applications of N was related to differences in number of spikes per unit area at harvest. The number of spikes/m2 decreased for wheat and increased for barley as the proportion of the N fertilizer applied at seeding decreased. Nitrogen fertilizer recovery in the straw and grain of wheat plants at harvest was 52.5 and 50.8% where 100 kg N/ha was applied at seeding or split between seediig and at irrigation, respectively. Percentage recovery of N fertilizer was lower in straw and higher in grain when N was applied at imgation as compared to seeding time application. Failure to obtain positive grain yield responses or increases in overall N fertilizer efficiency indicate no advantage to splitting N fertilizer applications between seeding and Irrigation for spring seeded wheat and barley on deep, medium‐fine textured soils

“…The second group received the same TiO 2 treatments as the first, but it received 51.3 mM SALIW. Fennel plants were exposed to NaCl concentration after 45 days from planting (during vegetative stage); selection age was used according to Schreiber [ 29 ] and Day [ 30 ]. To make irrigation water highly soluble NaCl salt was employed.…”

Background Fennel essential oils are fragrance compounds used in food and pharmaceutical sectors. One of the major impediments to expansion of fennel farming in Egypt's reclamation areas is saline water. Titanium dioxide (TiO2) or TiO2 nano particles (TiO2NP) can be utilized to boost the yield of aromatic plants cultivated under saline irrigation water. Saline water, particularly which contains sodium chloride can harm fennel plant; consequently, it was predicted that fennel production would fail in Egypt's reclaimed area, where the primary source of irrigation is groundwater consisting sodium chloride. This study sought to help fennel respond to sodium chloride by applying Ti forms to their leaves in order to reduce the detrimental effects of sodium chloride on them for expanding their production in the newly reclamation areas as a natural source of essential oil. Ti forms were applied as foliar application at 0, 0.1, 0.2 TiO2, 0.1 TiO2NP, and 0.2 TiO2NP, mM under irrigation with fresh water (0.4 dS m−1), or saline water (51.3 mM or 4.7 dS m−1). Results Plants exposed to 0.1 mM TiO2NP under fresh water resulted in the maximum values of morphological characters, estragole, oxygenated monoterpenes and photosynthetic pigments; while those subjected to 0.1 mM TiO2NP under saline water gave the greatest values of essential oil, proline, antioxidant enzymes and phenols. The greatest amounts of soluble sugars were recorded with 0.2 mM TiO2NP irrigated with saline water. Plants subjected to 0 mM TiO2 under saline water produced the greatest values of flavonoids, hydrogen peroxide and malondialdehyde. Conclusion To mitigate the negative effects of salty irrigation water on fennel plant production, TiO2NP application is suggested as a potential strategy.

“…Waxy starch (lower amylose, greater amylopectin) from certain food barleys provides snack foods longer shelf life and improved texture (10). Most N research with irrigated barley ( Hordeum vulgare L.) has focused on non‐waxy feed or malting varieties in sprinkler (8,9,11,12,14) or basin‐flood irrigation systems (13). These systems can provide better opportunities for effective N incorporation and potentially improved N utilization than the furrow irrigation (3) still common in the Pacific Northwest USA.…”

Waxy barley (Hordeum vulgare L.) with high amylopectin has value as a food crop, but information on optimal N fertilization of furrow‐irrigated waxy barley is limited. Furrow‐irrigated field studies were conducted at Parma, ID, and Ontario, OR, with ‘Merlin’ and ‘Salute’ spring genotypes planted fall or spring during the 2006, 2007, and 2008 seasons as the main plots and N treatments as subplots. “Early” N as dry urea was applied preplant or late winter (0, 60, 120, and 180 lb/acre) and “late” N was applied at heading (0 or 40 lb N per acre) to selected early N treatments. Late N was applied as top‐dressed dry urea (DU), foliar fluid urea (FU), foliar urea‐ammonium nitrate (FUAN, Parma only) or FU applied to ethephon‐treated barley (FUE, Ontario only). The optimal early N rate for Salute at Ontario was 0 with severe lodging or 60 lb N per acre, as compared to 60 or 120 lb N per acre for Merlin. At Parma, varieties did not differ in their yield response to N and optimal early N, ranged from 60 to 120 lb/acre. Yield increased as much as 1488 lb/acre with late N and was unaffected by late N source. Late N did not increase lodging or reduce apparent N recovery despite more total fertilizer N available. Ethephon controlled lodging sufficiently to improve yield 1439 lb/acre. Late N may allow producers to reduce the early N that contributes to lodging, and to both reduced yield and apparent N recovery.
