Planting Method

Most farmers’ practices broadcast sowing methods and productivity is less. Soil fertility maintenance is a major concern in tropical Africa which needs to tackle soil fertility depletion as a fundamental constraint. Similarly, the traditional way of planting tef reduces the amount of grain production, promotes competition for inputs, and causes severe lodging. This paper aimed to review the interaction effects between seed sowing methods and different types of inorganic fertilizers on the growth and yield of teff. In Ethiopia, recent research indicates planting method (row planting and broadcasting) affects the yield and yield components of teff. The review indicates the yield components include heading and maturity, plant height, first growth rate, number of tiller and panicle, thousand seed weight, grain, straw, and total biomass yields and harvest index high in Method of Row sowing compared to broadcast in Ethiopia but Days to emergence and panicle length were more affected by broadcasting. In economical acceptance, Row sowing was found to be economically acceptable with more income from grain yield than broadcasting.

Three popular tomato varieties namely, Ratan, BARI tomato-3 and BARI tomato-6 were experimentally evaluated to identify the potential mulch on growth and yield, where the experiment consisted of four mulching treatments viz. water hyacinth, straw, am-ada leaf and banana leaf with a control (no mulch). The experiment was conducted under rainfed condition. In the experiment, mulching showed significant effect on growth, yield components and thus on the yield of tomato. Yield contributing characters were significantly higher when water hyacinth mulch was used. The variety Ratan produced the highest (53.74 t/ha) fruit yield, while BARI tomato-3 showed the lowest (48.89 t/ha) fruit yield. The combination of mulching and variety exhibited significant variation in some yield components and yield. The combination of water hyacinth and Ratan produced the maximum yield (62.16 t/ha) and thus the experiment revealed that water hyacinth and straw mulches have potentiality to increase the yield of tomato.

Different Growth Stages

A field experiment was conducted in 2013 and 2014 at the Agriculture Experimental Station of King Abdulaziz University to study the effects of water deficit treatments at different growth stages on growth, yield and IWUE on cowpea cultivars. Four water deficit treatments were applied T0 (no water deficit), T1 (at vegetative stage), T2 (at flowering and pod setting), T3 (at pod filling), T4 (at vegetative and flowering) and T5 (at flowering and pod filling). The cultivars ‘Balady’ under water deficit T1, T3 and T4 and ‘Cream7’under T1 and T2 produced the highest yield component parameters except number of pods/plant. The highest yield of dry seeds kg/ha was produced by the cultivars ‘Cream7’ under water deficit T1 and T3 and ‘Balady’ under T2. ‘Cream7’ and ‘Balady’ revealed the highest irrigation water use efficiency (IWUE) under water deficit T1, T2 and T4. High seed yield of ‘Balady and ‘Cream7’ can be obtained by applying water deficit at vegetative stage (T1).

Objectifs : Cette étude se veut de produire et de déterminer la valeur fertilisante du vermicompost, et mesurer les effets de ce vermicompost sur la croissance et le rendement du maïs. Méthodologie et résultats : Les travaux ont d’abord consisté à élaborer un compost d’ordures ménagères puis son vermicompost associé par inoculation du ver de terre Eudrilus eugeniae (Kinb.), et ensuite à évaluer leurs effets sur la production du maïs à travers un essai conduit en milieu naturel au sein de l’Université Jean Lorougnon Guedé Daloa. Les traitements sont composés d’un témoin constitué d’un sol de jachère, d’un compost d’ordures ménagères associées aux balles de riz et du vermicompost correspondant. Les résultats ont révélé que le vermicompost a les teneurs les plus importantes en N, P et K, mais les plus faibles concentrations en Cu, Zn et Pb. Les plants de maïs croissent mieux sur le vermicompost par comparaison au compost et au témoin. De plus, le traitement de vermicompost a produit la biomasse racinaire (45,625 ± 1,812 kg.ha-1), le nombre de grains par plant (391,68 ± 17,20 kg.ha-1) et la biomasse totale des grains de maïs (2608,969 ± 50,914 kg.ha-1) les plus élevés. Conclusions et application des résultats : Les travaux ont révélé l’importance de l’espèce Eudrilus eugeniae dans la formation d’un compost de bonne qualité chimique. Les paysans peuvent utiliser le vermicompost d’ordures ménagères associées aux balles de riz pour améliorer le rendement des cultures de maïs. Mots clés : Vermicompost d’ordures ménagères, Balles de riz, maïs, croissance, rendement.

The present study was carried out to assess the existing status of compost usage on vegetable production and determine the overall effect of household waste compost (HWC) on growth and yield of vegetables and enhancement of soil fertility in the monga areas of Bangladesh. A field survey was conducted on 152 sampled farmers during 2010 to 2011. Questionnaire containing both closed and open-ended questions were used to assess existing production practices of vegetables using compost in both homestead and field conditions. Three field trials at Badargonj and Kawnia upazilas of Rangpur district were conducted taking four treatments i.e. control, recommended doses (RD) of fertilizers, HWC at the rate of 10 tha-1, and HWC 10 t ha-1 plus RD as IPNS based with Lal shak, Palong shak, Pui shak and Tomato. Base line survey results indicated inadequate knowledge of the farmers on use and preparation of the household waste compost. Yield data of all vegetables i.e. Tomato, Lal shak, Palong shak and Pui shak indicated that the combined application of nutrients using organic and inorganic sources were significantly better than that of solitary application of inorganic fertilizers. The potential of household waste compost applied @ 10 t ha-1 along with inorganic fertilizers applied was found highly satisfactory in producing Tomato, where yield was recorded 75 t ha-1 in the study area. The fresh yield of Palong shak was found 16 t ha-1 when recommended doses of inorganic fertilizers were applied, but it was about 19 t ha-1 under combined application of HWC @ 10 t ha-1 and inorganic fertilizers following IPNS concept. The fresh yield of Pui shak was found about 49 t ha-1 under combined application of organic and inorganic nutrients. Considering the availability and costs of different composts, it is evinced that HWC contained good amount of NPK which indicates its potentiality to be used as a soil amendment, improving soil fertility and crop productivity. It can be an alternative to chemical fertilizer to increase soil microbial populations and enzyme activities and to promote the soil nutrient for horticultural crops in the unfertile areas especially in the monga areas of Bangladesh.

A 2-year field study was conducted to determine the influence of planting method, i.e., transplanting or direct seeding, black plastic mulch, and soil fumigation on the vine growth, yield, and root structure of diploid hybrid watermelon. The experiment was a split-plot design with fumigation as the main plot and there were four replications. Methyl bromide (337 L·ha−1) was applied to the soil, which was then tarped. Black plastic mulch, 0.61 m wide × 2 mil (Visqueen 4020™) was applied to appropriate rows. Vine growth was measured during the season and yield was determined by the number and weight of fruit from each treatment. After fruit harvest, plant roots were excavated so that root structure was maintained with minimal damage and roots were photographed. Root systems were scored for tap root dominance and overall root distribution. Direct-seeded watermelon had more vine growth and higher yields in both years than transplanted watermelon. The advantage of direct seeding was likely the result of the growth and root expansion that occurred for these plants while the transplants were still in the greenhouse. Direct-seeded plants also displayed greater tap root dominance in each year than transplanted watermelon. Roots of both direct-seeded plants and transplants had a greater range in size distribution in both years under plastic mulch than those grown on bare ground. In late-planted watermelon, direct-seeded plants had more favorable vine growth and yield without the aberrant roots systems produced by transplants.

Maize Response

Maize response to high nitrogenous fertilization levels is a means among other means to know maximum productivity, from this perspective, a field nitrogen management trial using five N levels (0, 23, 46, 69 and 92 kg N/ha) with three replications. The study was conducted in 2015 in Decha District, ModyoGomberaKebele of Kaffa Zone, SNNPR State. The experiment was laid out in RCBD. The result of this study indicated that effects of different rates of N fertilizer had influenced the growth and yield components of maize. The tallest plant (360.66 cm) was recorded from the application of 92 kg N ha-1 and the shortest (347.33 cm) from no N application. The ANoVA for the number of kernels per ear showed that the lowest kernels per ear (497.86) were obtained from no N application and the highest kernels per ear (588) were obtained from the application of 92 kg N ha-1 although there was no significant difference between the application of 69 and 92 kg N ha-1. Regarding to ear length the data showed that the longest ear (23.63 cm) was obtained from the application of 92 kg N ha-1. The effect of N on  grain yield indicated that there is no significant difference between the application of 69 and 92 kg N ha-1 even if there is a slight difference on yield. Generally, maximum N fertilization level (92 Kg N/ha) in this study area showed increase in growth and yield components (number of kernels per ear and ear length). However the application of 69 kg N ha-1 seems adequate to get the optimum yield.
