“…Our results are also comparable with [12-14] who reported that P applied as a split dose at planting stage or different growth stages by the method of side dressing, or 2nd application with irrigation, resulted more grain yield as compared to full application at sowing time. Similar findings were also reported by [15][16][17][18]. Dry matter yield Dry matter yield of wheat was significantly increased over control with acidulation levels of RP, forms of P fertilizers and application methods at P< 0.05 ( Table 2).…”

The present study investigated the effect of different levels of acidulated rock phosphate (RP), liquid or solid and application methods on phosphorus use efficiency and wheat yield under calcareous soils of Peshawar during 2015-16. Treatments included acidulation of 100 kg RP with 7.5, 15, 30 and 45 kg H2SO4 equivalent to 25, 50, 100 and 150 % acidulation, applied in the form of either liquid or solid as single (no split) or two equal splits at sowing and knee height stage. The rate of P in all treatment was equal to 90 kg P2O5 ha-1. Our results showed that acidulation levels significantly increased wheat yield, post-harvest soil and plant tissue phosphorus optimum at 100 % acidulation level. Solid form of the acidulated RP was more effective than liquid revealing that lesser the contact of soil, could improve P availability from the source. It was further affirmed by the split application where it significantly increased the crop yield and P availability over no split irrespective of solid and liquid form. Our results suggest that solid RP with 100 % acidulation applied in two splits improved the crop yield, P use efficiency and could substitute commercial fertilizers under the prevailing soil and agroclimactic conditions.

“…This agrees with frequent reports of an inverse correlation between grain yield and percent grain protein (Loeffler and Busch 1982;Nass et al 1976). Hamid (1973) found that splitting N application of 120 kg ha -1 between seeding and stem extension gave higher N in the grain than applying all of that amount at seeding; there was slightly more N in the straw and greater recovery of fertilizer N in the grain and straw. Sandhu and Gill (1971) found split application (2-3 times) gave the best protein response to N.…”

. 2003. A protocol for spring milling wheat production in the Maritimes. Can. J. Plant Sci. 83: 715-723. Maritime cereal producers have had difficulty in producing spring milling wheat (Triticum aestivum L.) crops of 13.5% grain protein with consistency. A 3-yr study was conducted from 1999 to 2001 to develop a nitrogen management protocol to produce spring milling wheat with 13.5% grain protein. Experiments were conducted at three locations: Harrington, Prince Edward Island; Hartland, New Brunswick; and Truro, Nova Scotia. Ten split nitrogen treatments were applied to four spring milling wheat cultivars, AC Walton, Glenlea, Grandin and SS Maestro. Generally, any split nitrogen application of 75 to 100 kg ha -1 or greater produced grain protein of 13.5%. However, 10 cultivars out of 36 cultivar × site combinations failed to reach the desired 13.5% grain protein at any nitrogen treatment. Moisture stress after flowering, excessive precipitation during early plant development and protein dilution due to high grain yield were some of the possible reasons why 13.5% grain protein was not obtained. Milling quality was enhanced with increasing amounts of applied nitrogen because as grain protein increased, water absorption, development time, dough stability and time to dough breakdown increased while mixing tolerance index and 20-minute drop decreased. There was little or no improvement in milling quality with nitrogen applications greater than 75 to 100 kg ha -1 .Maritime grain producers can produce high-quality, high-yielding spring wheat with relatively low levels of nitrogen input; however, environmental factors may override management in determining the ultimate product quality. . Pour cela, les auteurs ont appliqué en deux fois un engrais azoté à dix parcelles sur lesquelles poussaient quatre cultivars de blé de printemps de qualité meunière (AC Walton, Glenlea, Grandin et SS Maestro). En général, l'application séparée de 75 à 100 kg ou plus de N par hectare donne du grain à 13,5 % de protéines. Toutefois, dix combinaisons sur trente-six de cultivar par site ne parviennent pas à cette concentration, peu importe la quantité d'engrais employée. Le stress hydrique après la floraison, des pluies excessives au début de la période végétative et la dilution des protéines attribuable à un rendement grainier élevé pourraient expliquer ce phénomène. La qualité meunière s'améliore avec la quantité d'engrais azoté utilisée, car l'absorption d'eau, la période de développement, la stabilité de la pâte et la durée du braquage augmentent avec la concentration du grain en protéines, tandis que le degré d'affaiblissement et la chute à vingt minutes diminuent. La qualité meunière ne s'améliore pas ou très peu lorsque la quantité d'engrais dépasse 75 à 100 kg par hectare. Les céréaliculteurs des Maritimes peuvent obtenir du blé de printemps de qualité et à rendement élevé avec une application relativement faible d'engrais azoté; néanmoins, les paramètres environnementaux pourraient l'emporter sur les pratiques culturales et détermin...
