“…The supremacy of 140kg N ha -1 is to be expected since this rate produced larger number of branches plant -1 (6.64 and 6.19), highest values for fruiting zone length (31.64 and 31.43cm), number of capsules plant -1 (22.21 and 20.72), 1000-seed weight (9.28 and 9.19g) as well as seed yield plant -1 (2.38 and 2.24g) in the two seasons, respectively. The significant effect and the marked seed yield increases by nitrogen levels were observed previously by many researchers among them Khajani et al (2012), Soethe et al (2013), Kariuki et al (2014), Andruszczak, et al (2015), Chopra & Badiyala (2016), El-Borhamy (2016), Patel et al (2017), Taddese & Tenaye (2018) and Yan et al (2018).…”

“…Thus nitrogen is a major element for plants since it is an important component of many structures of plant and for both their internal and external processes of metabolism. Many researchers applied nitrogen fertilization at different levels like Rahimi & Bahrani (2011) up to 150kg ha -1 , Khajani et al (2012) up to 90kg ha -1 , Soethe et al (2013) up to 200kg ha -1 , Kariuki et al (2014) up to 150kg ha -1 , Rahimi (2014) up to 150kg ha -1 , Andruszczak et al (2015) up to 80kg ha -1 , Chopra & Badiyala (2016) up to 30kg ha -1 , El-Borhamy (2016) up to 142.86kg ha -1 , Patel et al (2017) up to 90kg ha -1 , Taddese & Tenaye (2018) up to 138kg ha -1 , Yan et al (2018) up to 150kg N and 75kg P ha -1 . They found that any increase in N levels followed by an augmentation in straw and seed yields of flax as well as their related characters.…”

A T DAR-RAMAD Experimental Farm, Faculty of Agriculture, Fayoum University, Egypt, two field experiments were done during 2016/2017 and 2017/2018 seasons to investigate the effect of date of sowing and N rates on straw and seed yields of two Linum usitatissimum L. cultivars. The arrangement was done in split split-plot in RCBD with three replications. Date of sowing (i.e. November 10 th , November 25 th and December 10 th ) were allocated in the main plots. Flax cultivars (Sakha-1 and Sakha-2) occupied in the sub-plots, whereas, N rates (i.e., 35, 70, 105 and 140kg N ha -1 ) were distributed in the sub sub-plots. The obtained results showed that earlier sowing date in November 10 th significantly overtop middle and late sowing dates for straw and seed yield and related traits. Sakha-1 significantly surpassed Sakha-2 in studied straw yield traits, while, Sakha-2 exceeded Sakha-1 in seed yield traits. Nitrogen rate at 140kg ha -1 gave significantly higher straw and seed yields than other N rates which significantly vary from each other and this is true in both seasons. The regression analysis of seed yield specified that there are three traits, i.e. seed index, number of capsules plant -1 and seed yield plant -1 in 1 st season and two ones, i.e. seed index and number of capsules plant -1 in 2 nd season were significantly participated (P≤ 0.001) in variation of seed yield ha -1 .

“…The assimilate formation and allocation toward plant organs were closely related with phosphorus utility [39]. Higher P accumulation promoted assimilate production [40]. P accumulation can alter leaf nitrogen, which in turn increases assimilated formation and sucrose accumulation in the leaf [40].…”

“…Higher P accumulation promoted assimilate production [40]. P accumulation can alter leaf nitrogen, which in turn increases assimilated formation and sucrose accumulation in the leaf [40].

Planting Density Induced Changes in Cotton Biomass Yield, Fiber Quality, and Phosphorus Distribution under Beta Growth Model

et al. 2019

High input costs combined with multiple management and material inputs have threatened cotton productivity. We hypothesize that this problem can be addressed by a single fertilization at flowering with late sowing in a moderately populated plant stand. Field experiments were conducted to evaluate the cotton biomass accumulation, phosphorus dynamics, and fiber quality under three planting densities (low, 3 × 10 4 ; moderate, 6 × 10 4 ; and dense, 9 × 10 4 ha −1 ) and two cultivars (Zhongmian-16 and J-4B). High planting density had 6.2 and 12.6% larger stems and fruiting nodes m −2 , while low density produced a 37.5 and 59.4% maximum height node ratio. Moderate density produced 26.4-15.5%, 24.7-12.6%, and 10.5-13.6% higher biomass accumulation rate at the peak bloom, boll set, and plant removal stages over low and high density in both years, respectively. J-4B produced a higher reproductive organs biomass yield when compared with Zhongmian-16 in both years. This higher biomass formation was due to both the higher average (0.8 V T kg·ha −1 ·d −1 ) and maximum (1.0 V M kg·ha −1 ·d −1 ) reproductive organ phosphorus uptake, respectively. Plants with low density had 5.3-18.5%, 9.5-15%, and 7.8-12.8% greater length, strength, and micronaire values over moderate and dense plants, respectively. Conclusively, moderate density with J-4B is a promising option for improved biomass, phosphorus acquisition, and fiber quality under a short season.Agronomy 2019, 9, 500 2 of 18 nitrogen [6], water availability [7], planting date, and planting density [8] are factors that induce changes in dry matter formation and affect reproductive organ biomass accumulation.Biomass distribution in cotton organs during the crop cycle are important determinants of final yield. In the early phases of cotton growth, greater partitioning of foliar tissues enables access to light, which promotes better establishment and provides the basis for fiber quantity and quality later in the season. Similarly, during later growth phases, an increase in the assimilate transport to the reproductive structures ensures better crop yield. Planting density coupled with the cultivar are considered the key drivers for cotton production [8,9]. Due to its indeterminate growth habit, a cotton plant may invest heavily in vegetative biomass under optimum growth conditions. An over-investment of the assimilate into the vegetative or reproductive organs in cotton plants could stimulate the abscission of leaves or fruits, respectively [10,11]. The aboveground biomass of a cotton plant at maturity is often less than the total biomass produced as the plant may shed old leaves and young fruits [8]. Remobilization of biomass to reproductive structure may further reduce the total biomass of vegetative organs during late reproductive growth. Assimilate allocation, and thus the growth rate of a plant organ, is controlled by various environmental and physiological factors [12]. Generally, dry biomass formation and partitioning into organs is measured primarily during certain phenolog...

“…Since the concept of ionome is rst presented in 2003 [19], it has been used in the analysis of the responses to environmental factors in different plants [20], such as Arabidopsis (Arabidopsis thaliana) [21], tea (Camellia sinensis) [22], rice (Oryza sativa) [23]. With response to the variation of the genetic, developmental and environmental factors, elements are always bound to biological molecules [24][25][26], which are involved in lots of metabolisms, including carbon and nitrogen metabolism [27,28].…”

BackgroundPhosphorus (P) -rich soils develop in phosphorite residing areas while P-deficient soils are ubiquitous in subtropical regions. Little has been reported that how metabolites participate in the seed development and the processes involved in their coping with contrasting-nutrient environments.ResultsHere we quantified the metabolites of Quercus variabilis acorns in early (July), middle (August), and late (September) development stages at geologically-derived contrasting-P sites in subtropical China using Gas chromatography-mass spectrometry (GC-MS). The primary metabolic pathways included sugar metabolism, the TCA cycle, and amino acid metabolism. Most metabolites (especially C- and N-containing metabolites) increased and then decreased from July to September. Acorns between the two sites were significantly discriminated at the three stages, respectively, by metabolites (predominantly sugars and organic acids). Concentrations of P, orthophosphoric acid and most sugars were higher; erythrose was lower in late-stage acorns at P-rich sites than those at P-deficient sites. No significant differences existed in the size and dry mass of individual acorns between oak populations at the two sites. ConclusionsOak acorns at the two sites formed distinct metabolic phenotypes related to their distinct geologically-derived soil conditions, and the late-stage acorns tended to increase P-use-efficiency in the material synthesis process at P-deficient sites, relative to those at P-rich sites.
