SUMMARYSoil acidity, incipient potassium deficiency, and a deficiency of one or more trace elements were limiting factors in three trials of long-term soil fertility changes under continuous cultivation in the Sudan Savanna zone of Nigeria. The effectiveness of organic manures is explained largely or wholly in terms of these factors, since no evidence has yet been found to suggest that the addition of organic matter as such is of value.

SUMMARYInitial results of long-term trials in northern Nigeria indicate that deficiencies of potassium and trace elements, and soil acidity, may become important under continuous cultivation on some soils, in addition to the more common deficiencies of nitrogen and phosphorus.

Poor rainfall in 1972 and 1973 led to much of the area in the Sudan Savanna zone of Nigeria being declared a disaster area due to the widespread failures of major food crops under indigenous practices. However, in the same circumstances, a group of farmers using improved seed, fertilizer and better methods, obtained yields which were satisfactory. Crop losses from “drought” are a strong function of the cultivars grown and of the level of crop husbandry.

Maize Yields

Maize production in Malawi is limited by high costs and sub-optimal use of chemical fertilizers under continuous cultivation. A long-term gliricidia/maize trial was undertaken on a Ferric Lixisol from 1991/92 to 2001/02. The purpose of the study was to assess the performance of a gliricidia/maize intercropping system as a low-input soil fertility replenishment option in southern Malawi. The experiment was a 2 × 3 × 3 factorial design with three replications. Treatments included two maize cropping systems (with and without gliricidia trees), and three rates of inorganic N fertilizer (0, 24 and 48 N kg ha−1 representing 0, 25 and 50% of the national recommended N rate), and three rates of P fertilizer application (0, 20 and 40 P ha−1 representing 0, 50 and 100% of the recommended rate). No effect of P was detected on yield early in the trial, and this treatment was discontinued. The gliricidia pruning biomass did not decline after 10 years of intensive pruning, with strong correlation between tree biomass production and years after establishment (r = 0.91, p < 0.001). Application of gliricidia prunings increased maize yields by three times compared to the yield of unfertilized sole maize. Maize yield from the unfertilized gliricidia pruning treatment was superior to the yield from sole maize supplemented with a quarter or half the recommended N rate. The study confirmed that a gliricidia/maize intercropping system is a promising soil fertility replenishment option in southern Malawi and elsewhere in southern Africa.

Tidal Swamps

Tidal swamp land is one type of wetland in South Kalimantan, where the water level is influenced by the season/rainfall. Based on the puddle level and duration, tidal swamp land has three typologies, namely shallow tidal swamp, middle tidal swamp, and deep tidal swamp. The wetlands in Ampukung village are classified in tidal swamps.  Most of the tidal swamps have been utilized for agricultural activities, especially rice. Till now, rice farming in the tidal swamps of Ampukung village has not experienced any significant problems. In 2016, the rice harvest in Ampukung village exceeded the target of South Kalimantan. This success is considered to be increased by planting twice a year. However, some issues need to be addressed regarding the characteristics of the land in Ampukung village. Soil fertility, especially soil acidity, is one of the limiting factors in the utilization of tidal swamp land. Therefore, it is necessary to identify the acidity of the soil in the tidal swamp of Ampukung village. The acidity data is basic information to determine the condition of soil fertility to achieve the target of planting rice twice a year. This information will be presented in the form of a map to assist users in interpreting the research data. This study found that the soil pH in the tidal swamp lands of Ampukung Village, which was planted with rice, was highly acidic and homogeneously distributed.

Acid sulfidic land is one of the marginal land that has been used for oil palm development.  Low soil acidity (pH) and high content of Al and Fe are limiting factors for oil palm development in this area.  Oil palm yield in this area was very limited and could not reach the standard of oil palm productivity in mineral soils. The objectives of this study were mapping the pyritic depth distribution, and observing the soil fertility on three pyritic depth (40 – 60 cm, 60 - 90 cm, and >90 cm). The results of this study showed that Paya Rambe plantation had varied pyritic depths, between 40-110 cm. The shallow pyritic depth was found along the river to the sea estuary.  Shallow pyritic depth soil has lower soil fertility than the deeper one.  Soil with shallow pyritic layer has high acidity, Fe, S, and Al contents, also contain low macro nutrients (N, P, K, and Mg) availability.  Furthermore, shallow pyritic depth reduced the oil palm growth, nutrients uptake and oil palm productivity.

SummarySorghum is the principal foodcrop grown in Northern Nigeria. A survey of local varieties grown during the rains was carried out in 1958 and the 821 samples collected were assigned to seven morphologically distinct races, of which four are important. Varieties belonging to the Guinea race, with loose, open panicles, are mainly cultivated in high rainfall areas south of latitude 11°30′N. Further north, three races, Kaura, Farafara and Chad are grown in the dry Sudan Savanna zone. Varieties of these races have compact panicles and bulging grains. Estimates of the contribution made by each of the four major races indicate that the Guinea race accounts for nearly 50 per cent of the total sorghum production in Northern Nigeria.
