The effect of constant and fluctuating soil temperature and two soil moisture regimes on the growth, development, transpiration and nutrient uptake by maize seedlings was studied in a greenhouse investigation. The constant root temperatures were maintained at 30, 34, 35, 36, 37, and 38°C for both...

The grain yields in the no-tillage plots were equivalent to those of conventionally plowed treatments. No-tillage treatments had higher organic matter content and, by controlling soil erosion, the silt and clay content than the plowed plots. The water holding capacity and moisture release charact...

Mulching of yam seed beds reduced soil temperature and improved emergence, time of emergence, yield per hill and the total yield of Dioscorea rotundata yams on a sandy soil in Western Nigeria. Comparison of mounds with ridged and flat seed beds showed that these different treatments had no signif...

L'utilisation de paillis dans les lits de plantation reduit la temperature du sol et favorise la levee, Ie temps d'emergence, Ie rendement par poquet et Ie rendement global des ignames Dioscorea rotundata lorsqu'elles sont cultivees en sol sablonneux a I'Quest du Nigeria. Lorsque la comparaison a...

El cubrimiento de almacigos de name redujo la temperatura del suelo y mejore la emergencia, el tiempo de emergencia rendimiento por cepa y rendimiento total de name, Dioscorea rotundata, en un suelo arenoso de Nigeria Occidental. La comparacion de camas con almacigos alomados 0 pianos demostr6 qu...

The effect of mulching on maize yield was investigated for luvisol and cambisol tropical soils during 1970–72. The increase in grain yield by mulching was 46, 52 and 22 per cent respectively, for 1970, 1971 and 1972. Mulched plants had higher growth rate and vigour and chlorotic symptoms of nutri...
