Agricultural Water Management, 2021
Abstract Reducing use of irrigation water and improving crop yield are important since water shortage and food security are the two main problems in developing sustainable agriculture. In this study, we aim to reduce the conventional irrigation amount and to determine the mechanisms for yield formation and water use efficiency (WUE) increasing, and ...

Dry Weight Accumulation and Nutrient Uptake by Arracacha Grown Under Controlled Conditions [PDF]
, 1998 In Puerto Rico, the commerciaI production ofarraeaeha (Arracacia xanlhon-hiza) is concentrated in low fertility soils. Crop development and yield depend heavily upon supplementary fertilization. Information on arracaeha's growth and nutrient uptake is scarce.

Factors Affecting Dry Weight Accumulation in Developing Barley Endosperm
Physiologia Plantarum, 1987Some factors that may be concerned in determining final grain weight in barley (Hordeum vulgare L. var. distichum) have been investigated. Variation in endosperm fresh and dry weight, volume and starch content have been recorded at different stages of grain development between anthesis and harvest‐ripeness for two barleys, cvs Kym and Golden Promise ...

Rate of Accumulation of Dry Weight in Seed of Soybeans and Its Relationship to Yield
Canadian Journal of Plant Science, 1975The dry weight accumulation rate in soybean (Glycine max (L.) Merrill) seed was measured for 2 yr (1971–72), utilizing four cultivars and several planting dates within each year. Rates observed ranged from 3.38 to 8.32 mg/seed/day. There were significant differences among cultivars and planting dates.

Scientia Horticulturae, 1988
Abstract The rate of dry-weight accumulation was found to be higher in early- than in later-setting fruits and was unaffected by the water regime. Water stress shortened the duration of fruit growth and accelerated ripening. When expressed as final dry-weight yield, the proportion of fruit set during the first week of flowering was significantly ...

Journal of Agronomy and Crop Science, 1996
AbstractThe accumulation of dry matter and its major components was studied in developing grains of two bold seeded (Selection‐111 and IWP‐5308) and one small seeded (kalyansona) wheat genotypes grown in pot culture condition. It was observed that in kalyansona, a sharp reduction in grain water content during the critical stage of grain enlargement ...

Development and dry weight accumulation of pearl millet as affected by nitrogen supply
Field Crops Research, 1985Abstract Pearl millet ( Pennisetum americanum (L.) Leeke) was grown as spaced plants from seed to grain maturity under three levels of nitrate-nitrogen supply. The duration from sowing to panicle initiation depended on the number of developmental events (leaves produced) rather than requiring a constant time; it was greater at low nitrogen supply ...

Visual Markers of Maximum Grain Dry Weight Accumulation in Winter Wheat
Crop Science, 1991Visual indicators that coincide with the time of maximum grain dry weight accumulation (tmax) in hard red winter wheat (Triticum aestivum L.) have not been confirmed. Our objective was to evaluate various potential visual markers of tmax for a range of cultivars in typical Great Plains environments.

THE RATE OF DRY WEIGHT ACCUMULATION IN MARQUIS WHEAT AS AFFECTED BY TEMPERATURE AND LIGHT INTENSITY
Canadian Journal of Botany, 1962Plants were grown to the stage of anthesis at constant temperatures from 10 to 30 °C and under continuous illumination at intensities ranging from 200 to 2500 ft-c. The absolute growth rate was maximal at the time of ear emergence. The relative growth rate declined continuously with time; the rate of decline was greatest at the higher temperatures and

Physiologia Plantarum, 1989
Detached ears of three winter wheat (Triticum aestivum L.) varieties were cultured in solution for 12 days with sucrose levels varying from 36.5 to 292 mM. The dry weight and starch content of grains increased asymptotically with the sucrose level in the solution. At 4 days of culture, glucose phosphate isomerase (EC 5.3.1.9) activity grain−1 was lower
