Water scarcity is most threatening among these limiting factors. New techniques are being developed day by day to utilize the water efficiently. Application of water only in the plant root zone will be one of the water saving technique to grow crops. This will control the losses due to evaporation and leaching. Irrigation to soil does not control the climate variables and precipitation cannot be substituted to irrigation. Sprinkler irrigation could be one of the way to utilize the water efficiently by in time application and reducing the losses of leaching and evaporation along with amelioration of micro climate of the crop. Canals and tube well water is conventionally given to crop through flood irrigation. These fields are in direct threat of evaporation and leaching resulting in excess water losses and damaging the soil quality. The study was designed taking cotton as experimental crop to calculate comparisons in plant growth parameters and yields along with water saving ability of different irrigation system. Maximum yield was obtained from sprinkler irrigation and water was saved under drip irrigation system.","PeriodicalId":22617,"journal":{"name":"The Journal of Agricultural Extension","volume":"5 1","pages":"131-138"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73095917","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}

Two woredas were selected purposively based on the availability of avocado and banana production trends in the woredas. Then, a model avocado and banana producing female and male-headed households were identified and about 34 households were selected randomly from both woredas. A structured questioner was used to collect primary information from the selected households. The collected data were analyzed by STATA 12 software. The obtained results indicated that the male household members exceedingly participated in land preparation (93%), seedling preparation (90%), transplanting (90%) and weeding (76%) whereas, female household members highly participated in fruit collection (72%), transporting fruits to the market (83%), selling the fruit (90%) and deciding on money obtained from fruit sale (83%). The increased participation of female household members indicated that the contribution of female-headed households on many farming activities. The major criteria considered in selection of avocado varieties were plant height (75%), fruit size (75%), fruit yield (84%), fruit test (97%) whereas, fruit yield (91%), fruit color (72%), fruit test (94%) and fruit smell (53%) were important criteria for banana varieties. There were no statistically significant differences (P>0.05) in avocado and banana varieties selection criteria between female and male headed households. Therefore, breeders need not develop different avocado and banana varieties for female and male-headed producers. Gender based labor division in the study areas should be taken into consideration whenever technology is demonstrated and farmers' training is given on avocado and banana production technologies to ensure their effective implementation","PeriodicalId":22617,"journal":{"name":"The Journal of Agricultural Extension","volume":"67 1","pages":"77-83"},"PeriodicalIF":0.0,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76292030","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 advancement of the agricultural sector in rural areas is essential for reducing poverty among growers. As we all know, agricultural activities provide employment opportunities and generate income in rural areas. Poverty can be decreased by advancement in the agriculture sector for better production.

Pre- and post-intervention combined with treatment and control group designs were used. Data were collected from 232 Out-grower and 49 non- Out-grower farmers using interview schedules. Data were analysed using percentages, ttest and regression analysis. Assured markets (90.5%) and training on postharvest handling of crops (69.9%) were the most common supports received from Psaltry. Long bureaucracy involved in documentation (x =2.23) was the most severe constraint faced in the scheme. Total cassava harvested and productivity among Out-growers increased from 30,950.89±31,133.48kg to 106,116.88±96,926.01kg and 5,649.2±3835.3kg/Acre to 9,143.6±8799.1 kg/Acre before and after participating in Psaltry scheme, respectively. A significant difference existed between the productivity of Out-growers and non- Out-growers (t=7.256; p≤0.05). Membership of group (β=0.319) and length of involvement in the Psaltry scheme (β=0.157) positively and significantly influenced Out-growers’ cassava productivity. The Psaltry Outgrower scheme had stimulated beneficiary’s smallholder farmers towards higher productivity.

Two stage sampling procedure was used to select 315 respondents. Interview schedule was used in data collection. Data collected were analysed with percentages, Chisquare, the Pearson Product Moment Coefficient (PPMC) and simple regression model at α 0.05. The result revealed that the majority (80.6%) of the respondents used semi-mechanised method in processing Shea butter. The average unit price of Shea butter was ₦476.07K per Kilogramme, while the average income was ₦439,650.37K per annum. Processors had low level of accessibility to modern processing technologies (66.2%) and more than half (64.8%) of the processors were producing at low level. Lack of credit facilities and high cost of processing equipment were identified as severe constraint to Shea butter processing. There were significant relationship between level of education (χ²=11.18, p≤0.05), level of engagement (χ²=8.71, p≤0.05), income (r=0.819, p≤0.05) and accessibility to modern Shea butter processing technologies (r=0.164, p≤0.05) with level of Shea butter processing output. The major determinants of Shea butter processing output were income, household size, unit price and accessibility to modern processing technologies. Financial institutions should provide soft loans to Shea butter processors to acquire inputs and equipment. Similarly, government agencies should provide Shea butter processing equipment to the processors to improve access to the technologies that could lead to increase Shea butter production in Niger state. \u0000Keywords: Shea butter processing, determinants of processing output, technology accessibility and processors","PeriodicalId":22617,"journal":{"name":"The Journal of Agricultural Extension","volume":"29 1","pages":"53-61"},"PeriodicalIF":0.0,"publicationDate":"2020-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76313012","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}
