“…Therefore the highest level of striga infestation across most study sites occurred in soils low in organic matter and available phosphorous. This result is in lined with the findings of Samaké et al (2005) who stated that striga infestation is strongly associated with decline of soil fertility, thus the problem is aggravated as a result of the decline of soil fertility.…”

(16) respectively. Whereas, the lowest density of Striga shoots per plant of sorghum was registered at Genetie (4), Mentebteb (4), Rawyan (5), May Shek (7), Kara Adishabo (7) and Mitsa Werki (7). The highest level of Striga infestation was recorded at sites which had got the highest population density of sorghum, sites with low organic matter and available soil phosphorous content and sandy textured soils. Management practices channeled towards improving these limitations have been suggested for controlling of S. hermonthica in the region.

“…4,5,6,7), resulting in specific strategies of when and where to use the limited amount of manure available (Table 5). Soil fertility differences are important for farmers when they make decisions on crop allocation, and these differences are amplified by farmers' management in many regions, leading to preferred plots for the best crops (Samake et al 2005;Tittonell et al 2006Tittonell et al , 2007Wortmann and Kaizzi 1998). The use of manure is almost always beneficial for crops (Affholder 1995;de Rouw 2004;Zingore et al 2008).…”

In large regions of sub-Saharan Africa, semi-arid conditions are likely to increase with climate change, yet these regions are becoming more important to feed production zones due to increasing population pressure. A production system in the semi-arid south eastern Zimbabwe was studied to assess different possible growth conditions of food crop in relation to seasonal differences, spatial rainfall distribution, use of organic nutrients and different position in the landscape. The growth and yield of four crops (maize, sorghum, millet and groundnut) were assessed with or without manure during two seasons (2008/2009 and 2009/2010) in different landscape positions. Daily rainfall, soil and manure nutrient levels, seed germination, crop establishment, grain yield and above-ground residue biomass were measured. Most important determining factors of crop yield were landscape position and the different within season rainfall distribution of the two seasons. Manure increased yield of sorghum grown in upland and maize grown in lower lowlands. Millet was affected by Quelea quelea birds, the reason why it is unpopular in south eastern Zimbabwe. Best-fit strategies can double total yield from 1.67 to 3.29 t/ha from the average 5.1 ha that farmers usually crop in south east Zimbabwe. Farmers in semi-arid areas can reduce risk of total crop failure by making a clever use of both the low lying and the upland areas depending on crops of their interest.

“…For instance, in these systems, it has been reported that erosion can lower soil productivity by at least 10-20 % due to a reduction of SOC and nutrients and to related negative impacts on other soil properties (Delgado et al 2013). In developing countries, the lack of affordable nutrients and soil mining makes crops entirely reliant on soil organic matter (Samaké et al 2005).…”
