Modeling Fiber Fineness, Maturity, and Micronaire in Cotton (Gossypium hirsutum L.)
Published 2013-01-01Get full textCrop performance is determined by the combined effects of the genotype of the crop and the environmental conditions of the production system. This study was undertaken to develop a dynamic model for simulating environmental (temperature and solar radiation) and N supply effects on fiber fineness, ma...

A new feasible method for yield gap analysis in regions dominanted by smallholder farmers, with a case study of Jiangsu Province, China
Published 2021-02-01Get full textIn the regions where crops were mostly produced by smallholder farmers, the analysis of yield gap is difficult due to diverse cultivars, crop managements and yield levels. In order to find an effective method that can reasonably verify the yield gap and the limiting cultivation factors in narrowing...

Nitrogen Concentration in Subtending Cotton Leaves in Relation to Fiber Strength in Different Fruiting Branches
Published 2013-10-01Get full textNitrogen (N) fertilizer experiments were conducted to investigate the optimal subtending leaf N concentration for fiber strength, and its relationship with activities of key enzymes (sucrose synthase and β-1,3-glucanase) and contents of key constituents (sucrose and β-1,3-glucan) involved in fiber s...

Relationships between temperature-light meteorological factors and seedcotton biomass per boll at different boll positions
Published 2018-06-01Get full textCotton growth and development are determined and influenced by cultivars, meteorological conditions, and management practices. The objective of this study was to quantify the optimum of temperature-light meteorological factors for seedcotton biomass per boll with respect to boll positions. Field exp...

Hormonal changes play important roles in the key period of superior and inferior earshoot differentiation in maize
Published 2021-12-01Get full textThe upper earshoots with higher superiority usually have higher yield potential and higher efficiency. To determine the key period for the asynchronous differentiation of superior and inferior earshoots and how hormones are involved in this process, a two-year experiment was designed using two maize...

Effects of planting dates and shading on carbohydrate content, yield, and fiber quality in cotton with respect to fruiting positions
Published 2018-05-01Get full textTwo cotton (Gossypium hirsutum L.) cultivars, Kemian 1 (cool temperature-tolerant) and Sumian 15 (cool temperature-sensitive) were used to study the effects of cool temperature on carbohydrates, yield, and fiber quality in cotton bolls located at different fruiting positions (FP). Cool temperatures...

The effects of sowing date on cottonseed properties at different fruiting-branch positions
Published 2017-06-01Get full textA two-year field experiment was conducted to illustrate the effects of sowing date on cottonseed properties at different fruiting-branch positions (FBPs). Two cotton cultivars (Kemian 1 and Sumian 15) were sowed on 25 April, 25 May, and 10 June in 2010 and 2011, respectively. The boll maturation per...
