“…1992;Janzen et al, 1987;Williams et al, 2000). Similarly, our results of significantly lower yield of wheat after wheat compared with wheat after fallow agree with previous findings (Lindwall et al, 1995;Mrabet, 2011;Smith et al, 2008). Length of fallow for sorghum after sorghum was less than for sorghum after wheat, and, similarly, the length of fallow for wheat after wheat was less than wheat after fallow (Fig.…”

Yield and Soil Water in Three Dryland Wheat and Grain Sorghum Rotations

Diverse crop rotations sustain crop productivity by increasing crop water productivity and improving soil structure. Th e objective of this study was to compare two 4-yr winter wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor L.) rotations in terms of grain yield, available soil water, and water productivity along with continuous winter wheat. A fi eld study was conducted from 1996 through 2015 on a deep silt loam soil near Tribune, KS. Th e study consisted of three crop rotations: continuous annual wheat (WW), wheat-wheat-sorghumfallow (WWSF), and wheat-sorghum-sorghum-fallow (WSSF). Grain yield, biomass, water productivity, and soil water were all greater for sorghum aft er wheat compared with sorghum aft er sorghum. Similarly, grain yield, biomass, water productivity, and soil water were all greater for wheat aft er fallow compared with wheat aft er wheat. Th e yield of the second wheat crop was 80% of the fi rst wheat crop in WWSF, whereas the yield of a second sorghum was only 63% of the fi rst sorghum crop in WSSF. Th e average crop water productivity (7 kg ha -1 mm -1 ) of the WSSF rotation was greater than the other rotations. On average, the WSSF system produced 2.05 Mg ha -1 yr -1 wheat equivalent yield (WEY), which was similar to the 1.96 Mg ha -1 yr -1 WEY from the WWSF rotation and greater than WW, which produced 1.53 Mg ha -1 yr -1 of wheat grain. A WSF rotation would have produced 2.0 Mg ha -1 yr -1 WEY, so the 4-yr rotations were not more productive than a 3-yr WSF rotation.

“…A significant effect of various rotations on biomass and wheat HI was also reported (López-Bellido et al, 2000;Mrabet, 2011;Turner, 2004). Rotations that increase grain yield by facilitating better nutrient and water use often increase biomass as well.…”

“…Inherent poor fertility of the soil and low use of organic and inorganic fertilizers have been identified as some of the greatest constraints to increasing agricultural productivity in Nigeria. Also with the population growth, demand for land has increased resulting in intense cultivation with little or no fallow periods and the reliance on continuous cropping rather than conservation cropping systems (Ismaila et.al., 2010;Muhamman and Gungula, 2006;Mrabet, 2011). Inappropriate farming methods on marginal land, deforestation and overgrazing and continual cropping beyond soil threshold limits results into high depletion of the soil (Aruleba and Ajayi, 2011;Cassman, 1999;Tekwa et.…”

“…Hence under this environmental condition, Good soil management practices are essential to maintain sustainable production to meet the current high demand for cereal crops in Nigeria. To increase the yield stability in cereal crops is important in Nigeria of which more than 70% of the population that live in Savannah region of Nigeria depend largely on small subsistence farming with the productivity of their farming systems being very much limited by soil condition (Kano Soil Health project, 2010;Mrabet, 2011). It is claimed that productivity of the farming systems could only be maintained or sustained through the efficient recycling of organic material such as manure or crop residues in combination with mineral fertilizers and by adopting rotations with grain legumes (Tarawali, 1998).…”

Soil management practices are known for their efficiency in combating land degradation issues and improving soil productivity, but generally there are low usage levels of these practices by the farmers. The study analyses the influence of socioeconomic factors on the attitude of farmers towards soil management practices in Kwara State. The specific objectives were to determine the soil management practices carried out by cereal farmers in the area and to examine the socio-economic factors affecting the use of soil management practices in cereal based production in the study area. A random sampling technique was used to collect data from 118 cereal farmers in the study area. Descriptive statistics and regression model were the analytical tools used. The study shows that ridging (94.1%), crop rotation (74.6%) and use of fertilizer (69.5%) were the most common soil management practices among the farmers. Logistic regression model highlighted factors like Age, farm size, number of contacts with extension agents, total labour used and total number of plots cultivated with cereals to influence the use of soil management practices by the farmers.The study recommends that farmers should be encouraged to make use of soil management practices which will bring about soil improvement and also improve their productivity.

“…Although, Rhizoctonia species are not among the top ten pathogens [1], economic importance of their control is increasing from severe to catastrophic yield losses reported from main wheat cultivating areas [2][3][4]. Changes in agricultural practices of cereals with special regard to minimum or no tillage cultivation [5,6] led to increased importance of Rhizoctonia infections [7,8]. The most plausible method is the breeding of tolerant varieties.…”

Response of 3 Arabidopsis clones to 41 strains of eight Rhizoctonia species was studied in model experiments. The seed germination was decelerated in most of the cases, although the inhibitory effect varied within large limits. The pre-emergence damping off and root neck rot leading to damping off were the most frequent symptoms of disease syndrome caused by toxic metabolites. The clone transformed with cDNA clone overexpressing gstf4 gene exhibited significantly improved tolerance as compared to parental one, meanwhile the sensitivity of Dmannose pyrophosphorylase/mannose-1-pyrophosphatase deficient clone dramatically increased. Strains of R. solani of AG-2, AG-4 and AG-7 and Athelia rolfsii produced the most toxic metabolites, however, no strict relationships were revealed between taxonomic position of Rhizoctonia strains and toxicity of their metabolites.
