The "System of Rice Intensification"(SRI) represents a sustainable alternative to improve household yields and incomes. This study aimed to evaluate the yields and the profitability of the SRI and the Traditional Practices (TP) in Ziguinchor district, Senegal. A directed sampling based on criteria for selecting the system used and the cultivated varieties common to both systems was applied to collect the yield parameters and yields of paddy rice. Thus, 18 producers in the Badiate, Essyl, and Fanda sites were selected, nine per system and four 1 m2 yield squares were installed in each selected producer plot. A total of 72 yield squares, 36 per system, were installed, and an individual questionnaire was randomly administered to 55 producers using at least one of the systems to collect data on rice production and costs. The yield parameters including the number of fertile tillers per m2, the number of spikes, the weight of the 1000 grains are significantly higher (p<0.05) in the SRI including yield compared to the traditional system. Transplanting density and plant duration are higher in TP (26±5.6 plants/m2 and 26 days) than in SRI (16±0.4 plants/m2 and 16 days). The lower the transplanting density, the higher the yield parameters and the yield. The economic profitability, determined based on the benefit/cost ratio, is higher in SRI (1.5) than in TP (1.2). The SRI required a lot of technicality in its implementation and generated more cost of production. However, SRI was more productive and economically more profitable than the traditional system.

Cattle Rearing

This study was borne out of the fact that rice farming and cattle rearing are predominant in the northern parts of Nigeria. But there have been increasing conflicts between farmers and herdsmen particularly in north-central. To address this problem, this study empirically looked at the nexus between sensitization on gains from paddy grazing and farming practices in rice production. Data were collected from three hundred and twenty respondents with the aid of a structured interview guide and field survey. It was found that instead of using organic manure, Urea (55%) and NPK (36.9%) fertilizers were applied on the rice farms. Most (89.4%) of the respondents were not sensitized on the benefits of paddy grazing to the dairy cattle, environment, and soil. Results of the t-test indicated that no significant difference existed in the farming practices for rice production in Niger and Benue States (t = 8.9). The level of sensitization on paddy grazing correlates with the farm practices of the respondents (r = 0.69). This study concluded that respondents did not aware that paddy grazing could lead to increased rice and milk production.

AbstractSignificant studies on the sound systems of Edoid languages have been conducted, but studies of the internal relations that may exist within them are rare. Linguistic and nonlinguistic correlates of Northern Edoid features have been identified, thereby laying out broad phonetic and phonological indices for identifying this group of languages. Esan is classified as North Central Edoid. The goal of this study is to address the need to further define internal linguistic relations within the languages which constitute this linguistic group. Specifically, this study seeks to identify an order of historical emergence of identified Esan speech varieties.The study is lexicon based. Data were gathered from one adult native speaker from each of the twelve identified Esan speech varieties making a total of twelve informants. The Ibadan word list of 400 basic items served as an instrument. Available data were transcribed in phonetic tradition and subjected to sound identification procedures. A comparative analysis of the sound systems which emerged for each identified Esan speech variety, separated them into eight groups in the following order: Udo-Ugboha-Ubiaza; Ebhoato-Igueben-Ilushi; Uromi; Ekpoma; Ohordua; Ogwa; Irrua; Ugbegun. The first group of Esan speech varieties exhibit speech sound characteristics that indicate that it is an earlier form of the language. Ubiaza exhibited further linguistic indices to suggest that it predates its counterpart Esan varieties.Although this study is not aimed at reconstructing Esan, its findings serve as input to such a goal as well as to dialect studies of the language. It provided an avenue for the documentation of Esan speech forms. The outcome of this study contributes to further similar linguistic studies on Esan and other Edoid Languages.

Cereal Production

This study estimated technical efficiency levels of cereal crops producers. The study employed the translog stochastic frontier model to estimate efficiency levels of maize, rice and sorghum producers in the survey area. Findings revealed that maize and sorghum farmers were operating in the efficiency range of 0.50 to 0.98, while for rice farmers efficiency estimates ranged between 0.71 and 0.98. Fur- thermore, it was also observed that a majority of the rice farmers operate in the range 0.91 and 0.98 efficiency levels. Also, about 18% of the farmers operate in the efficiency range of 0.81 and 0.90, while just about 14% operate in the range of 0.96 and 0.98 efficiency levels for rice production. Findings suggest that, all things been equal, most of the cereal crops producers could improve their current levels of production by adjusting their input combination.

Cropping Seasons

Rice production is a significant source of greenhouse gas (GHG) emissions in the national budget of many Asian countries, but the extent of emissions varies strongly across agro-environmental zones. It is important to understand these differences in order to improve the national GHG inventory and effectively target mitigation options. This study presents a meta-analysis of CH4 database emission factors (EFs) from 36 field sites across the rice growing areas of Vietnam and covering 73 cropping seasons. The EFs were developed from field measurements using the closed chamber technique. The analysis for calculating baseline EFs in North, Central and South Vietnam in line with the Intergovernmental Panel on Climate Change (IPCC) Tier 2 methodology was specified for the three cropping seasons being early-(E), mid-(M) and late-year (L) seasons. Calculated average CH4 EFs are given in kg ha−1 d−1 and reflect the distinct seasons in North (E: 2.21; L: 3.89), Central (E: 2.84; M+L: 3.13) and South Vietnam (E: 1.72; M: 2.80; L: 3.58). Derived from the available data of the edapho-hydrological zones of the Mekong River Delta, season-based EFs are more useful than zone-based EFs. In totality, these average EFs indicate an enormous variability of GHG emissions in Vietnamese rice production and represent much higher values than the IPCC default. Seasonal EFs from Vietnam exceeded IPCC defaults given for Southeast Asia corresponding to 160% (E), 240% (M) and 290% (L) of the medium value, respectively.
