Two hundred S 1 generation selfed seeds of maize (Zea mays L.) along with their parents (nine) and few checks (sixteen) were raised in ear-to-row progenies during post rainy season 2012 with two replications, were evaluated under stress condition by using lattice square design (15x15). The analysis of variance indicated highly significant differences for eighteen characters except relative wate...

A database of nearly 2000 yield observations from winter wheat crops grown in UK trials between 1976 and 1993 was used to develop a new model of effects of weather on wheat yield. The intention was to build a model which was parsimonious (i.e., has the minimum number of parameters and maximum predictive power), but in which every parameter reflected a known climate effect on the UK crop-environ...

Two field experiments were conducted in 2009 and 2010 to evaluate some physiological traits and yield of three hybrid rice varieties (BRRI hybrid dhan2, Heera2, and Tia) in comparison to BRRI dhan48 in Aus season. The experiments involved four planting dates (1 April, 16 April, 1 May and 16 May). Compared to BRRI dhan48, hybrid varieties accumulated greater shoot dry matter at anthesis, higher ...

Translocation of nitrogen was measured in wheat (Triticum aestivium L. cv SUN 9E) plants grown without an exogenous supply of nitrogen from the time that the flagleaf began to emerge, and a model of nitrogen translocation was constructed to describe translocation on one day during the linear period of grain growth. Nitrogen for grain development was derived entirely by the redistribution of nit...

The remobilization of water soluble carbohydrates (WSC) has an important role for grain yield. This study investigated the accumulation and remobilization of WSC in non-leaf organs (chaff, upper stem, and lower stem) and their contribution to grain yield, under different irrigation levels (rainfed, reduced irrigation, and full irrigation) and seeding rate treatments (450, 600 and 750 plants...

Wheat plants (Triticum durum Desf., cv. Regallo) were grown in the field to study the effects of contrasting [CO(2)] conditions (700 versus 370 μmol mol(-1)) on growth, photosynthetic performance, and C management during the post-anthesis period. The aim was to test whether a restricted capacity of sink organs to utilize photosynthates drives a loss of photosynthetic capacity in elevated CO(2)....

Post-anthesis drought affects wheat production worldwide, primarily through the limitation of grain filling. The enhanced remobilization stem reserves induced by can provide considerable carbon sources for aim this study, which was part an ongoing wheat-breeding program targeting tolerance, to assess ability 20 contrasting common genotypes (2 cultivars, 8 F6:7 families (FAM), and 10 parent (PAR...

Plastic film mulching (PM) is widely utilized for maize production in China. However, the effect of PM on the grain yield of crops has not been established, and the biochemical mechanism underlying the increase or decrease in grain yield under PM is not yet understood. Grain filling markedly affects the grain yield. The objective of this study was to investigate the effects of PM on maize grain...

Winter wheat production is threatened by drought stress under rainfed conditions; thus, screening high- and stable-yielding varieties to ensure the sustainable development of food security in Huang-Huai-Hai Plain (HHHP) vital. In this research, four-year field experiments with twelve winter were conducted during wheat-growing seasons between 2016 2020 order to: (1) screen conditions, (2) invest...
