Effect of fertilizer dose on the performance of spring cereals

Abstract

In country like Pakistan where population is growing at an alarming rate, food shortage is the top challenge for researchers. To contribute to this effort, field trials entitled "Effect of fertilizer dose on the performance of spring cereals" were conducted at Cereal Crops Research Institute Pirsabak Nowshehra, Khyber Pakhtunkhwa, Pakistan during 2010-2011. The experiment was laid out in RCB design with split plot arrangement replicated three times, with plot size 5X1.8m, having 6 rows 30cm apart. Fertilizer doses were allotted to main while cereal species were allotted to subplots. Fertilizer dose, cereal species and their interaction had significantly affected cereal performance. Application of 60:30:30 and 120:60:60 (N:P:K kg ha-1) significantly affected plant height and phenology of cereals than no NPK. Application of 60:30:30 and 120:60:60 produced 55% and 62% more grain yield respectively than no NPK. Wheat, triticale and oat phenology was significantly delayed, oat and triticale produced taller plants than wheat and barley. Triticale yield was significantly higher than barley, wheat and oat. In case of interactions triticale with 120:60:60 NPK took more days to heading (131) and physiological maturity (168), while barley took less days to heading (109) and physiological maturity with no NPK. Significantly taller plants were produced by oat (129 cm) at 120:60:60 while barley produced dwarf plants (73cm) with no NPK. In case of grain yield, triticale produced more yield (5275 kg ha-1) with 60:30:30 while oat gave lowest yield (2433 kg ha-1) with no NPK. It is concluded that triticale and barley performed well on less fertile soil than wheat and oat. For optimum production, 60:30:30 and 120:60:60 (N: P: K kg ha-1) are recommended for barley/triticale and wheat/oat respectively, in conditions similar to Nowshehra.

Optimizing blended (NPSB) and N fertilizer rates for the productivity of Durum wheat (Triticum turgidumL.var. durum) in Central Highlands of Ethiopia

“…This result is consistent with the report of Muhammad et al (2016) who indicated that wheat plants grew under increased rates of nitrogen fertilizer supply delayed days to headings than those grew low rates of the nutrient. Similarly, Harfe (2017) reported that as the N level increased from nil to 69 kg ha −1 , the days to 50% heading was delayed from 67.58 to 70.04 days of bread wheat.…”

Seeding and Blended NPSB with Nitrogen Fertilizer Combined Rates Effect on Growth, Yield and Yield Components of Bread Wheat (Triticum aestivum L.) in South Ari, Southern Ethiopia

“…The result indicated that days to heading delayed as the rate of fertilizer application increasing suggesting enhanced vegetative growth (delay by 7.03%) due to fertilization, nitrogen application in particular. The resulted was in line with the report of Muhammad et al [20] who indicated that "wheat plants grew under increased rates of nitrogen fertilizer supply delayed days to headings than those grew lower rates of the nutrient". "Increasing nitrogen level from zero to 69 kg ha −1 showed delayed days to heading, from 67.58 to 70.04 days of bread wheat" [21].…”

Physiological Growth Indices of Durum Wheat (<i>Triticum turgidum</i> L. Var. durum) as Affected by Rates of Blended and Nitrogen Fertilizers

“…This result is consistent, indicated that wheat plants grew under increased rates of nitrogen fertilizer supply delayed days to headings than those grew low rates of the nutrient. Moreover, the N level increased from nil to 69 kg ha -1 , the days to 50% heading was delayed from 67.58 to 70.04 days of bread wheat [21,25]. The result of present study is contrary; found that N at the rate of 64 kg ha -1 significantly reduced days to heading of tef over the control [26].…”
