Journal Article 1983

Autor: Mambani, B. Lal, R.

The effects of variable soil moisture regimes along a toposequence on root development, plant water status, and grain yield were investigated for ten rice varieties: (1) 63-83, (2) IB 43, (3) OS 6, (4) IB 6, (5) IR 1529-680-3, (6) C 22, (7) IRAT-13, (8) TOS 4680, (9) IET 1444 and (10) SE 302 G. T...

Journal Article 1974

Autor: Lal, R.

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...

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...

Journal Article 1978

Autor: Lal, R.

Measurements were made of physical characteristics of 119 samples from 23 profiles derived from two parent materials in Nigeria. The laboratory analyses included texture, plasticity and shrinkage characteristics, and a range of soil moisture constants including saturation point and moisture reten...
