Nitrogen demand from soybean seeds during seed filling is very high and has been proposed as the cause of nitrogen remobilization and leaf senescence Previous research has not shown consistent effects of late season fertilization on seed yield while its effects raouf_ssharifiuma ac ir Email: لوئسم هدنسیون * 1399 زییاپ 3 هرامش 22 هرو{445-460 یاههحفص میدسدع دش پ هرود لوط و ییا ه گ ،د کلع ب یتسی یاهدوک و لوناتم ، تراتسا ژو تین ثا

Effects of nitrogen and tiller type on grain yield and

The rate of nitrogen (N) fertilizer application is strongly related to crop yield the number of spikelets per panicle and grain filling of late emerging tillers were significantly lower than that of the main stem or early emerging tillers at all N levels Effects of nitrogen and 6-benzylaminopurine on rice tiller bud growth and changes

However the effect of N application on grain yield and grain protein varies according to the time of application Nitrogen applications can be delayed until the end of tillering –start of stem elongation (GS30-31) without a significant effect on yield or in some cases an improvement in yield (Figure 3a)

Then follow this up with an additional shot of about 20-30 pounds of N in late winter or early spring to support spring tillering possibly applied with herbicides Finally come back around jointing or a few days later with a final application to support heading and grain fill Application Method Most topdressing is broadcast applied

Regarding the whole period of grain filling late fertilizer applications have also been shown to reduce the efficiency of N remobilization (Gooding et al 2007) Conversely Tribo and Tribo-Blondel (2002) noted that plants with a lower N ant and hence a lower N rem capacity have a greater propensity to take up nitrogen after anthesis

Effects of Nitrogen Fertilizer Application on Grain

Abstract In order to explicit the characteristics of superior and inferior grain filling and its relationship with rice quality of super japonica rice Xindao 18 a field experiment with 7 and 6 N fertilizer application levels was carried out in 2011 and 2012 respectively on the farm of Xinxiang Academy of Agricultural Sciences Henan Province China

Jul 12 2019Thus foliar applications N solutions are the most efficient method to improve grain protein when applied during the early stages of grain fill The amount of grain protein that can be expected will likely be 50% to 95% of the amount of supplemental N applied No effects on grain yield test weight or kernel weight can be expected

Nitrogen application at heading increased grain protein regardless of initial N rate at all sites though the degree of increase depended on conditions of N fertilization and initial soil N Where initial N rates were in excess of the optimum at Bozeman grain protein levels were increased by only 0 2 to 0 3% with late-season N application whereas

amount of dry matter for grain filling thus improve the productivity of rice [5-10] On the other hand it has been reported that the amount and time of nitrogen application had tremendous effects on filling and dry matter accumulation in rice [11-19] There has been a close relationship between grain filling

Nov 01 2019It was hypothesized that the shift in fertilizer N availability imposed by late N applications would not impact the establishment of potential yield (pKN and pKW) but would facilitate the maintenance of KN and KW during the linear phase of grain-fill In addition the effect of late N application on N uptake was also investigated 2

showed T2 (nitrogen application in tillering steam elongation and grain filling) as well as T4 (nitrogen application in sowing tillering and grain filling) had the most effect on grain yield increasing (Table 2) Result of N rates and its timing interaction effects indicates that maximum wheat grain yield was obtained from 240 kg N ha -1 when it

Yield-increasing effect of late nitrogen application The yield components including the number of panicles grains and setting percentage were significantly affected by cultivar which indicates that the 1000- grain weight is a relatively stable component in indica hybrid rice varieties

Late Season Water and Nitrogen Effects on Durum Quality

Abstract Durum grain quality is affected by many factors but water and nitrogen are factors that the grower can control The purpose of this research was to determine 1) the nitrogen application rate required at pollen shed to maintain adequate grain protein levels if irrigation is excessive or deficient during grain fill and 2) if nitrogen applications during grain fill can elevate grain

Nitrogen-15 Amino Acid Feeding to Leaves At the late milk development stage (Zadoks decimal code DC 77) corresponding to the beginning of rapid synthesis and accumulation of hordein in grain according to Shewry () two main culms per plant were selected and the apical tip (2–3 cm) of the penultimate leaf (second leaf below the spike) of each culm was removed with a razor blade

Thus foliar applications N solutions are the most efficient method to improve grain protein when applied during the early stages of grain fill The amount of grain protein that can be expected will likely be 50% to 95% of the amount of supplemental N applied No effects on grain yield test weight or kernel weight can be expected

Nitrogen rates by time of application also showed significant effects on both biomass and grain yield of maize in each season (Figure 4) In 2013 the highest significant biomass yield (21 2 tha −1 ) was obtained at 115 N kg ha −1 and (four times split application of equal doses) followed by 69 N kg ha −1 at and and 92 N kg ha −1 at

Key words: Effects of nitrogen Grain filling Zea mays Phenology Growth stages Abstract An experiment was conducted to see the effects of nitrogen at different growth stages on phenology rate and grain filling period of maize Nitrogen rates (0 75 150 and 225 kg/ha ) were arranged in main plot and time of nitrogen application in sub plots

Jun 15 2011One can conclude that the yield differences among these sidedress treatments were due to a combination of effects that occurred during ear size determination and on kernel survival during grain fill At harvest the V15 sidedressed plots yielded 100 bu/acre more than the starter-only control and only 13 bu/acre less than the traditional V7

The influence of nitrogen (N) fertilizer application rate (0 vs 70 vs 140 kg N ha –1) and timing (early = at sowing vs late = at sowing and before heading) on the amount of protein groups amount and size distribution of mono‐ and polymeric proteins and gluten strength was investigated in one set of wheat cultivars (Triticum aestivum L ) Due to their genetic background the cultivars

Can Late-Split Nitrogen Application Increase Ear Nitrogen Accumulation Rate During the Critical al (1989) observed a significant main effect of hybrid and a hybrid N rate interaction but no impact of N rate alone on ear growth or Nc from the leaves early in the grain-filling period is an impor -

To achieve superior rice-grain quality more emphasis has been placed on the genetic diversity of breeding programs although this improvement could be seriously restricted in the absence of comparable agricultural management practices Nitrogen (N) application and planting density are two important agronomic practices influencing rice growth yield and grain quality

Nitrogen rates by time of application also showed significant effects on both biomass and grain yield of maize in each season (Figure 4) In 2013 the highest significant biomass yield (21 2 tha −1 ) was obtained at 115 N kg ha −1 and (four times split application of equal doses) followed by 69 N kg ha −1 at and and 92 N kg ha −1 at
