Irrigation, Planting Date And Intra-Row Spacing Effects On Soybean Grown Under Dry Farming Systems
(
Qatar University
, 1987 , Article)
Two soybean cultivars (Glycine maxima (L) Merr.) differing in maturity period, leaf size and stem height were sown five times at fortnight intervals during the rainy season at four intra—row spacings under supplementary ...
Physiological growth analysis of the life-history of calotropis procera (AIT.) AIT. F.
(
Qatar University
, 1992 , Article)
Growth of Calotropis procera was analysed by distribution of dry weight throughout the plant at various stages in growth. Dry biomass, leaf area index, specific leaf area, leaf weight ratio, leaf area ratio, net assimilation ...
Apical dominance in vicia faba l.
(
Qatar University
, 1983 , Article)
A side-effect of plant surgery was an interference with apical dominance. From the results of three experiments involving plant surgery, decapitation and the usage of "C-IAA, it appeared that the movement of the apically ...
Studies on the biology of eucalyptus micro theca f. Muell in the gezira, sudan i. The behaviour of the seed
(
Qatar University
, 1986 , Article)
Eucalyptus microtheca has proved to be a success on the heavy clay soils of the Gezira. This tree species not only seeds regularly and prolifically during the summer, but also, though rarely, seeds during the winter. The ...
Plant Population Density Effects On Yield Of Sorghum Grown In A Dry-Land Farming System
(
Qatar University
, 1996 , Article)
Plant population studies in arid regions are very sparse and not well documented. A prerequisite in growing a successful sorghum (Sorghum bicolor [L.] Moench) crop is to obtain an adequate plant population. The response ...
Studies in bidirectional movement in vicia faba l.
(
Qatar University
, 1984 , Article)
Surgery was used to investigate bidirectional movement in a single vascular bundle of Vicia faba L. In one experiment it was found that radiocarbon had moved upwards and downwards via one isolated bundle when leaf one and ...
A comparative study of the effects of clumping, substrate, light, depth of burial and soil moisture upon the germination of seeds of weeds and crops grown in the sudan gezira.
(
Qatar University
, 1985 , Article)
The influence of the number of seeds per clump upon germination of oryza sativa L., Gossypium hirsutum L., Brachiaria eruciformis (Sm.) Griseb, Dinbera retroflexa (Vahl) Panz. and Echinochloa colonum (L.) Link was investigated ...
Calcium Carbonate Content, Some Chemical And Physical Properties Of The Sudan Gezira Soils And Their Implications
(
Qatar University
, 1991 , Article)
Eight soil pcdons representing a range of aridisols, vertisols and recent alluvium were studied for various chemical and physical properties. Generally the soils were clayey except the recent alluvium which was loamy but ...
Floating capital pattern and biomass slope allocation method in the life history of calotropis procera (AIT.) AIT. F.
(
Qatar University
, 1992 , Article)
Plants of the woody perennial Calotropis procera (Asclepediaceae) were grown from seed to seed-set in an open field. Smith's slope allocation and fractional-allocation or percentage methods were used to study dry matter ...
Some Aspects Of The Autecology Of Panicum Turgidum Forsk
(
Qatar University
, 1983 , Article)
The germination of Panicum turgidum seeds was tested under different conditions. They showed ability to germinate under a range of temperatures from 25-42°C. The maximum percentage of germination was 45%, at 30°C. The ...
