Other claims from this paper (12)
- Intervention effect About 15 kg N/ha gave optimum groundnut production.
- Observation Groundnut needed 32 and 48 kg/ha of N in a dry season on coarser soils and in all seasons on a finer soil, respectively.
- Intervention effect Application of up to 30 kg P/ha increased groundnut yields on all soils under savannah vegetation except the finest textured one.
- Intervention effect Phosphorus did not increase groundnut yields on the soil under forest vegetation.
- Intervention effect Application of up to 495 kg gypsum/ha increased groundnut yield.
- Intervention effect Application of up to 495 kg gypsum/ha reduced the number of “pops.” in groundnut.
- Intervention effect Application of all the P at planting produced higher groundnut yields than split application, with a greater effect during stress and at low gypsum rates.
- Intervention effect Timing of P applications had no effect on the number of “pops.” in groundnut.
- Intervention effect Repeated applications of the respective fertilizers increased soil P and K in all four soils.
- Observation Accumulated soil P and K amounts were small relative to the quantities applied.
- Association Potassium accumulation in soil increased with the clay content of the soils.
- Observation Total N increased in two soils only.
