Grain yield, and dry matter and nitrogen accumulation and remobilization in durum wheat as affected by variety and seeding rate [PDF]

European Journal of Agronomy, 2006
Abstract The influence of crop density on the remobilization of dry matter and nitrogen from vegetative plant parts to the developing grain, was investigated in the durum wheat ( Triticum durum Desf.) varieties Creso, Simeto and Svevo cultivated in the field at three seeding rates, 200, 250 and 400 seeds m −2 . Variety × seeding rate interaction was

Rates of apparent photosynthesis, respiration and dry matter accumulation in maize canopies

Biologia plantarum, 1993
The rates of canopy apparent photosynthesis (PC) and canopy respiration (Rc) were studied during vegetation season in two erectophile and two planophile hybrids of maize (Zea mays L.) grown at two canopy densities [7.5 plants m-2 (HD) and 4.5 plants m-2 (LD)].

Effect of the Rate of Nitrogen Application on Dry Matter Accumulation and Yield Formation of Densely Planted Maize

Sustainability, 2022
Planting maize (Zea mays L.) reasonably densely and adding amounts of appropriate nitrogen fertilizer are essential measures to improve the efficiency of maize yield and nitrogen use. In this study, two planting densities of 7.5 × 104 plants ha−1 and 12.0 × 104 plants ha−1 were established with the maize varieties DengHai 618 (DH618) and XianYu 335 ...
