Sowing and application of mineral and organic fertilizer is generally done manually in the Sahel, resulting in low precision and delayed application. The objective of this paper is to present a new mechanical planter (Gangaria) for the combined application of seeds and soil amendments (mineral fertilizer, compost, etc.), and to assess the effects of using this planter in pearl millet on labor use, yield and economic return. The labor study showed that the mechanized application of seeds and compost reduced time use by a factor of more than six. The on-station experiments were completely randomized experiments with six replications and six treatments: T0 (control), T1 (0.3 g NPK hill−1), T2 (25 g compost hill−1), T3 (25 g compost + 0.3 g NPK hill−1), T4 (50 g compost hill−1) and T5 (50 g compost + 0.3 g NPK hill−1). Treatments T1 to T5 were sown by the planter with seeds that were primed in combination with coating of seeds with a fungicide/insecticide. The treatment T5 increased grain yield and economic return compared to the control by 113% and 106%, respectively. The advantages for farmers using this approach of agricultural intensification are timelier sowing of dryland cereal crops, easy application of organic fertilizer and more precise delivery of input, thereby making this cropping system more productive and less vulnerable to drought.

<p>Pearl millet is an important crop for people living in semi-arid areas in Uganda but not much is known about its production environment. A survey was conducted in eastern and northern regions of Uganda to characterise the pearl millet cropping system and to identify the most important production determinants. Using questionnaires, data was collected from 160 households through face-to-face interviews with the respondents. Results showed that pearl millet was mainly grown for food and source of income. The production environment was low input as farmers planted unimproved genotypes, used no artificial chemicals or manure, and had minimal access to financial credit and agricultural trainings or extension services. Planting was done in the second rains with no optimal use of important resources like family labour and seed due to seed broadcasting. Farmers desired genotypes with traits such as; stay green, being tall, high tillering, high yield, early maturity and being ergot resistant. The most important constraints were ergot and rust diseases susceptibility, low yield, low tillering, late maturity, sterile panicles, rodents, moulds/rotting and insect pests; while lack of market, low prices and price fluctuation were the important market constraints. Results further showed that farmers lacked knowledge about the common diseases like rust and ergot. The area planted, spouse age and years of pearl millet cultivation were the important factors enhancing production while age of household head, amount of seed planted and distance to the market negatively affected grain yield.</p>

SUMMARYA study was carried out in the rainy seasons of 2008 and 2009 in Niger to investigate the effects of fertilizer micro-dosing on root development, yield and soil nutrient exploitation of pearl millet. Different rates of diammonium phosphate (DAP) were applied to the soil at different depths and it was found that although micro-dosing with DAP increased grain yield over the unfertilized control to a similar level as broadcast DAP, doubling the micro-dosage did not increase it further. Increasing the depth of fertilizer application from 5 to 10 cm resulted in significant increases in root length density, and deep application of fertilizer resulted in higher yields, although the increases were generally not significant. It was postulated that the positive effect of micro-dosing resulted from better exploitation of soil nutrients because of the higher root volume. Levels of nutrients exported from the soil were at least as high in plants receiving micro-dosing as the unfertilized control, and plants receiving micro-dosing exported 5–10 times more phosphorus from the soil than the amount added through fertilization.

&lt;p&gt;&lt;strong&gt;Abstract&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;Cowpea, a food and nutrition security crop is being threatened by decline in soil fertility especially in small holder farmstead. The natural arbuscular mycorrhizal fungi in the soil could improve its ability to acquire and retain nutrients thereby leading to higher yield. This irrigated field research was conducted to determine the effect of biochar rates and cropping systems on selected soil chemical properties, soil microbial biomass carbon (SMBC), nitrogen (SMBN), phosphorus (SMBP), and vesicular-arbuscular mycorrhizal (VAM) spore count and mycorrhizal fungi colonization (AMF) of cowpea. Experimental design was 3 x 3 factorial in randomized complete block design (RCBD). Factor A was three cropping systems; sole cowpea, intercropping and intra-cropping, while factor B was three biochar rates; control (biochar at 0 t ha&lt;sup&gt;-1&lt;/sup&gt; (B&lt;sub&gt;0&lt;/sub&gt;)), biochar at 2.5 t ha&lt;sup&gt;-1 &lt;/sup&gt;(B&lt;sub&gt;1&lt;/sub&gt;) and biochar at 5 t ha&lt;sup&gt;-1&lt;/sup&gt; (B&lt;sub&gt;2&lt;/sub&gt;). These were replicated in three blocks to constitute 27 plots. The entire plot was cleared, ploughed and demarcated into beds with hoes and diggers. Cowpea sole or inter- or intra- cropped with maize were planted in a spacing distance of 25cm by 75cm, with intercropped cowpea being in-between the interrow spacing (75 cm), while the intracropped cowpeas was planted between the intrarow spacing (25 cm). Biochar soil amendment were applied two weeks after planting by making a groove in-between the rows in the soil and covering them with soil. The result showed that biochar soil amendment and interaction of biochar with cropping system significantly (p&lt;0.05) affected SMBN, SMBC, total&amp;#160; VAM spore count and AMF colonization by cowpea, whereas cropping system significantly affected only total VAM spore count and AMF colonization by cowpea. B&lt;sub&gt;2&lt;/sub&gt; amended soil had the highest SMBC content (0.028 mg kg&lt;sup&gt;-1&lt;/sup&gt;) while the least was from control plot (0.021 mg kg &lt;sup&gt;-1&lt;/sup&gt;), SMBN was highest in B&lt;sub&gt;1 &lt;/sub&gt;amended soil (0.004 mg kg&lt;sup&gt;-1&lt;/sup&gt;), followed by control plot (0.002 mg kg&lt;sup&gt;-1&lt;/sup&gt;). Control had higher AMF and total VAM spore count while biochar amended soil had higher soil microbial properties. Considering the cropping systems, inter and intra-cropping had higher microbial biomass and total VAM spore count than sole cowpea whereas sole cowpea had higher AMF infection of cowpea than the intercropped cowpea. Biochar at 5 tha&lt;sup&gt;-1&lt;/sup&gt; had the highest available P. Generally, this study showed superiority of the interaction of biochar with cropping systems over sole cropping in the improvement of soil properties in degraded soils of North-West province of South Africa.&lt;/p&gt;&lt;p&gt;Key words: Cropping systems; Chromic Luvisol; Microbial properties; Soil fertility; Soil amendment&lt;/p&gt;
