Irrigated agricultural land comprises less than a fifth of all cropped area but produces 40–45% of the world’s food. It is generally expected that irrigated agriculture will have to be considerably extended in the future in order to feed growing populations (an additional 1.5–2 billion people by 2025, according to United Nations population projections). However, it is not yet known whether there will be enough water available for the necessary extension. As it is very likely that water demands of the domestic and industrial sectors will increase in the future, even regions that do not have water scarcity problems today such as Zambia, will be restricted in their agricultural development and thus possibly their food security by a lack of water availability [1].","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"858 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134062792","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}

Data was obtained from the respondents through a well structured questionnaires and interview schedule. In this study, a total of 60 fish farmers were selected using multistage sampling techniques. Descriptive statistical tools were used to analyze the socio economic characteristics of the farmers and constraints facing them. Gross margin analysis was used to analyze costs and return. DEA analysis was used to determine their efficiency, while tobit regression model was used to analyse determinants of efficiency. The study revealed that about 68.3% chose fish farming as their minor occupation, 63.3% engaged in fish farming for family consumption, 86.7% did it for sales. 70% have 1-5 years of fish farming experience, 66.67% have 1-10 years of farming experience, 75% operated only 1 pond each. 40% of the respondents acquire their land through inheritance, 46.7% used earthen pond, 76.7% are members of cooperative society and 66.7% had no access to credit. The finding shows that fish farming was profitable with net farm income of N374100.09 per fish farmers in the study area. Majority of the fish farmers are relatively technical efficient in their use of resources with mean technical efficiency of 84.9%, 89.0%, 95.5%, under CRS, VRS, and SE respectively. Farmers’ sex and fish farming experience had inverse relationship with the efficiency of fish farming in the study areas, farmers’ age had direct relationship under both CRS and VRS, while access to credit had direct relationship with efficiency under SE specification. The analysis shows a slack of 4.184kg, 2,972.091m,2,411.008kg, N112,119.49 and 2,284.597; in fish output, pond size, feed, labour and number of fingerlings respectively. Major problem facing the fish farmers were limited access to credit, marketing, transportation and access to quality feed. The study therefore concluded that measures should be taken to improve technical efficiency, in order to bridge the gap between fish demand and supply, to bring about self sufficiency in fish production.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"4 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":"134393539","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}

The experiment was conducted validate blended fertilizer to develop site and crop specific optimum rate recommendations based on Ethio-SIS soil fertility map in Halaba, southern Ethiopia, during the 2019 cropping season. The experiment was consisted of six treatments levels: (1) control or unfertilized, (2) farmers’ practice (100 kg ha -1 of NPSB + 50 kg ha -1 of Urea), (3) 100% of the recommended rates of N and P which is-138 N and 92 P, (4) 50% of the recommended rates of N and P from blended (NPSB) fertilizer and urea, (5) 100% of the recommended rates of N and P from blended (NPSB) fertilizer and urea and (6) 150% of the recommended rates of N and P from blended (NPSB) fertilizer and urea. The treatments were arranged in randomized complete block design with three replications. The result revealed that the maximum grain yield (8,240 kg ha -1 ), straw yield (18,435 kg ha -1 ) and biomass yield (25,858 kg ha -1 ) of maize was obtained from application 150% of recommended rate nitrogen and phosphorous from NPSB blended fertilizer plus urea source. The economic analysis indicated that the application of 150% of recommended rate nitrogen and phosphorous from NPSB blended fertilizer and urea source were gives net benefit value of (107113.50 ETB ha -1 ) with MRR of (9%). These results suggest that an appropriate use balanced fertilizer based on site and crop specific not only provides enough nutrients to the soil but also improves crop production and productivity. There for application of 150% of recommended rate nitrogen and phosphorous from NPSB blended fertilizer and urea source based on Ethio-SIS soil fertility map can be recommended to farmers for maize producers, that with assurance of economic returns in Halaba, Southerm Ethiopia and areas with similar agro-ecological and soil conditions.

Low test weights tend to result from poor grain fill and environmental conditions in the field before harvest. The 1000 grain weight is a very important measure of seed quality, which is effective on sprouting, seed potential, seedling growth, and plant performance (Hossein Afshari et al., 2011).

The objective of this work is to evaluate access to the PAA and the PNAE by family farmers within the Transamazonian Territory, which is a central region in the Brazilian Amazon. To obtain the information, semistructured questionnaires were applied to the implementing organizations and the farmers who benefited from the aforementioned programs in the year of 2014. The data obtained was analyzed by way of descriptive and inferential statistics. A reduced access to these programs was observed, which is associated to a strong bureaucratic process, a delay in the approval of projects (PAA), a delay in payment by the city halls, difficulty in issuing invoices and political instability within the cities (PNAE). The conclusion was that the effectuation of these programs is directly related to the socioeconomic and productive dynamics of the cities, and depends on the participation of farmer organizations, buying agents and especially on the political will of the managers.","PeriodicalId":117425,"journal":{"name":"International Journal of Research Studies in Agricultural Sciences","volume":"1 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":"122186310","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}

Cassava is the third most important source of calories in the tropics (FAO, 2010) and the sixth most significant food crop after rice, maize, sugar cane, wheat and potato, in terms of global annual production (FAOSTAT, 2010). Cassava global annual production is approximately 291.9 million tons with Africa contributing more than 177 million tons, which is about 60.9% of global production (FAOSTAT, 2019). Added to this, Nigeria has the largest contribution to global productivity, with an annual production of about 59 million tonnes (FAOSTAT, 2019), more than Abstract: The quest to establish cassava cultivars with increased yield, pest and drought resistance has led to the establishment of several cassava germplasms but with little or no independent study on these germplasms. Hence, we employed basic morphological and anatomical protocol to ascertain the similarities and variabilities among 10 cassava germplasms and their potentials for yield, pest and drought resistance. Cassava germplasms were grown in soil-filled polypots, maintained at 50% field capacity and parameters like plant height, leaf area, petiole length, petiole insertion type, lobe margins, nature of cuticles, number of vasculatures in stems and petioles, presence/absence of trichomes in midribs and estimated area of vascular bundles were measured at 45 days after planting. Data collected were subjected to descriptive statistics and petiole insertion type, reticulate venation, lobe margin and number vasculatures in stems revealed similarities among all germplasms studied, thus indicating an identical ancestral origin. Nonetheless, variations were observed in plant height, leaf area, nature of cuticles, petiole length, number of vasculatures in petiole and presence/absence of trichomes in midrib. Germplasms like TMS 95/0289, TMS 95/0166, TMS 92/0057, TMS 91/02324 were among the top performing lines on plant height, petiole length, leaf area and number of vasculatures present in the petiole and Pearson coefficient correlation among these four parameters revealed a strong positive relationships statistically significant at p < 0.05, thus indicating that these germplasms will contribute to breeding of cassava cultivar with improved yield capabilities, as the selection of one of these parameters will positively influence others. Germplasms like TMS 96/0166, TMS 97/0211, TMS 9/1089A and TMS 98/2101 were top performers on qualities of drought and pest resistance via the presence of trichomes, thick leaf cuticles, reduced number of petiole vasculatures and area of vascular bundles in both petioles and midribs.
