The study investigated the roles urban women played in cassava processing in Imo State, Nigeria. Multistage sampling procedure was used to select a sample of 100 rural women farmers. Data were collected from the respondents using interview schedule. Data were analysed using percentage and mean statistic. The major cassava products available in the area included fufu (91.7%), garri (90.5%), cassava balls (70%) and abacha/tapioca (65.2%). The roles they played included pounding (98.0%), peeling (97.8%), frying (97.0%), cooking (96.7%), sifting (95.0%) and boiling (95.0%). The constraints faced by the women included poor market demand ( = 3.5), unstable power supply ( = 3.4), inadequate information on processing ( = 3.3), the long period of time spent on processing ( = 3.4) and inadequate finance ( = 3.3). It was recommended that loans should be made available to the women to enable them cope with the constraints.

Faba bean seeds are the most important legumes in terms of consumption, for its positive nutritional properties and the most important diseases of Faba bean seeds are damping off. The field experiments was carried out during the 20172018 and 2018-2019 seasons to study the effect of the biocontrol agents as well as Rizolex T on the incidence of Faba beans damping off disease. The growth parameters, yield and its quality parameters of Faba bean plants were also, studied. The cultures of Paenibacillus polymyxa, Pseudomonas fluorescens and Bacillus megaterium bacteria and the Trichoderma viride, Trichoderma. harzianum fungi were used. The results exhibited that, the highest percentage of preemergence damping off reduction, the maximum plant height and the maximum seeds weight per plant were recorded with Rizolex T and P. polymyxa followed by B. megaterium and T. harzianum treatments. Significantly increases in the percentage of survived plants compared with the control were found in all treatments. Number of branches, and number of pods per plants were the highest in the Rizolex T treatment. Quality parameters of the faba bean crops resulted, such as protein, protein digestibility and minerals (Fe and Zn), as well as, total flavonoid and antioxidant activity evaluations were significantly increased in P. polymyxa, B. megaterium followed by Rizolex T compared with control samples. Technological evaluation of density, ratio between cotyledons and seed coats, as well as, water absorption, hydration coefficients and swelling coefficients after soaking and cooking were studied and showed high levels in Faba beans treated with P. polymyxa, B. megaterium and Rizolex T. Also, high level of cookability (stewing) and sensory characteristics were detected in Faba beans treated with P. polymyxa, B. megaterium and Rizolex T compared with other treatments and control.

The Irrigation uniformity plays an important role in the performance of the sprinkler irrigation system and for good plant quality; however, sprinkler systems are typically gauged by the uniformity of water application above the crop canopy. The objectives of this study were to evaluate the hydraulic performance including: uniformity coefficients (CU %), distribution uniformity (DU %) and application efficiency (Ea %) and soil moisture distribution under center pivot. This study was conducted under central pivot irrigation systems (eight units) at the farms of Authority of Merowi Dam Area for Agricultural Development (AMDAD) in New Hamdab Scheme, Northern State, season 2016/17. Results showed that the volume of caught water ranged from 135.2 to 419.3 mm with an average of 5.05, 3.86 and 11.98 mm for central pivot 1, 5 and 8, respectively. However, the application efficiency (Ea %) of the central pivot irrigation system no. 1, 5 and 8 were 36.1, 27.6 and 85.6 %, respectively. The results showed that uniformity coefficients (CU%) of the center pivot irrigation system were 40.9% and 74.4% for center pivot no.1and 5, respectively which were generally below the recommended value while center pivot no. 8 (84.4 %) was in the range recommended. The water distribution uniformity (DU %) values were 57.4% and 77.5% for center pivot no.1and 5, respectively which were generally below the recommended value except center pivot no. 8 (84.3 %) was in the range recommended. The water distribution uniformity (DU %) values were 57.4% and 77.5% for center pivot no.1and 5, respectively which were generally below the recommended value except center pivot no. 8 (84.3 %). The results of soil moisture (MC%) were 3.47, 2.66 and 8.29% for center pivot no.1, 5 and 8 in depth 0-30cm, respectively they showed a clear variation between centers while the change didn’t exceed 1% in depth 30-60cm. Results of soil moisture uniformity (SCU %) and soil moisture distribution (SDU %) in depth 0-30cm were below the recommended value for all centers, however, the irrigation requirement was not satisfied and, hence, resulted in low yield. Generally, among the three systems, both 1 and 5 showed lower performance than 8. Hence, the test of performance for a center pivot irrigation system should be carried out each season.

The water distribution uniformity (DU %) values were 57.4% and 77.5% for center pivot no.1and 5, respectively which were generally below the recommended value except center pivot no. 8 (84.3 %). The results of soil moisture (MC%) were 3.47, 2.66 and 8.29% for center pivot no.1, 5 and 8 in depth 0-30cm, respectively they showed a clear variation between centers while the change didn’t exceed 1% in depth 30-60cm. Results of soil moisture uniformity (SCU %) and soil moisture distribution (SDU %) in depth 0-30cm were below the recommended value for all centers, however, the irrigation requirement was not satisfied and, hence, resulted in low yield. Generally, among the three systems, both 1 and 5 showed lower performance than 8. Hence, the test of performance for a center pivot irrigation system should be carried out each season.","PeriodicalId":346845,"journal":{"name":"Middle East Journal of Agriculture Research","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130416639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
