The research used structured questionnaires to interview 240 rice farmers in the Mbeya region. The findings revealed that farmers accessed agricultural information from various agents including local government extension staff, neighbors and friends, advertisements, electronic media including the internet, television, radio, and other channels. The identified technological information application methods included by lectures, field demonstrations, exposure visits to various places, and printed production. The majority of farmers perceived to have dissatisfied (43%), strongly dissatisfied (25%), strongly satisfied (20%), satisfied (8%), and no opinions (4%) concerning accessibility to agricultural information and technological services. The majority of farmers claimed that both agricultural information and technological communication are strongly needed for agricultural performance. The study suggests that government and non-government organizations should collaborate to bridge the existing information-sharing gap between farmers and  information providers. \u0000Keywords: extension communication, technological information, rural areas, rice farmers, Tanzania.","PeriodicalId":22617,"journal":{"name":"The Journal of Agricultural Extension","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82396070","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}

Soilorganic matter increased by over 9% in the amended treatment relative to the control treatment. Except for N, increases in P (circa 14-70%)and K (circa 15-46%) nutrients were higher for CkD treatment than in other  treatments. Generally, the amended treatments maintained a significantly higher (p ≤0.05) plant leave number, stem girth, plant height, okra pod length and yields when compared with the Control treatment. The results indicated that application of animal manure enhanced okra growth performance. The findings suggest that animal manure application can potentially increase okra yield when grown in a degraded soil.

Perhaps, due to inadequate awareness and scanty literature, the aspect remained ignored. This study was an attempt to determine the simultaneous relationship between environment, informal sector, and poverty. This study was based on panel data study of three countries, Pakistan, Bangladesh, and India. ARDL approach was used to measure the size of the informal sector economy of Pakistan, India, and Bangladesh. The generalized momentum (GMM) method was applied to determine the environment's simultaneous effects, on poverty, and the informal sector economy. The outcomes unveiled that informal sector employment and poverty expedited the carbon dioxide emission in three countries such as India, Pakistan and Sri Lanka. Secondly, poverty and CO2 emissions had a positive association with the informal sector whereas thirdly, there was a negative impact of the informal sector economy and CO2 emissions on the poverty. This study urges to channelize the informal sector because it can contribute towards poverty reduction in a better way once its channelized and provision of adequate awareness among the people regarding judicious use of natural resources. For instance, climate smart agriculture, sustainable farming and Good Agricultural Practices have been implemented to curtail the CO 2 emissions from agriculture sector. The needs are to provoke other sectors as well followed by the initiation of legal restrictions on CO 2 emissions","PeriodicalId":22617,"journal":{"name":"The Journal of Agricultural Extension","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83908973","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}

Thus, in view of the increased water scarcity, an adequate management for water application is required to maximize water use and increase yield. In this regard, a field trial comprising four deficit drip irrigation treatments on potato crop under drip irrigation was conducted in filed condition using RCB design with four replications. Cropwat 8.0 program was used to determine the interval and depth of next irrigation at 15, 30, 45 & 60% management allowable depletion (MAD) of soil moisture. The outcomes indicated that irrigation to potato crop at 30% MAD level gave the highest water productivity (17.28 kg/m3) followed by 60, 15 and 45% MAD levels. Maximum %age of medium sized tuber was achieved by applying irrigation to potato crop at 60% MAD level (65.70) followed by 30% MAD level (65.5), 45% MAD (64.0) and 15% MAD level (60.50). The incidence of scab was found 2.50%, 2.75%, 3.25% and 3.75% in potato tubers at 15, 30, 45 and 60% MAD level, respectively. Thus, growers can save the water by adopting this water saving technique without reduction in tuber yield. For proper adaptation of new technique and practice, common farmer of Pakistan should be educated in term of visits to govt. research institutions and adoptive research farms to understand the right step to words better yield.","PeriodicalId":22617,"journal":{"name":"The Journal of Agricultural Extension","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80308252","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}

Total 360 respondents selected through snowball sampling technique were interviewed through face-to-face interview technique on a structured, validated and pretested interview schedule. Collected data were analyzed through Statistical Package for Social Sciences (SPSS). Findings unveiled that a little more than half (56.7%) of respondents had experience of family farming surpassing over 15 years. Greater than half (51.2%) of respondents had overwhelmed reliance on farming only in order to generate income. This study confirms that, personal factors (wandering, studentship, dependency on elders and lack of confidence), cultural (litigation, social injustice, generational gap), marketing (inflation, crashed marketing) and farming related factors (small land size, high production cost, land ownership, poor return and labour intensiveness) were the key factors hindering the participation of rural youth in family farming. This study urges a pivotal role of agricultural institutions to assist and train youth for the persuasion to join family faring. Government should be on board the policies to make agriculture a profitable venture, thus the youth can be mobilized to participate in family farming. The concept of family farming is also required to be familiarised among youth through interactive approach of media.","PeriodicalId":22617,"journal":{"name":"The Journal of Agricultural Extension","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84688235","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}

However, the country’s wheat productivity is not as impressive as that of China, India and Bangladesh. Punjab shares more than 70 percent of the country’s total area cultivated under wheat crop. Although the application of farm inputs in their optimal quantities translate into improved wheat yield, however the qualitative attributes of the agronomy applied to wheat production as well as the socioeconomic realities of the wheat growers also matter for better output. Keeping in view the role of wheat as a staple diet in Pakistan along with its strong backward and forward linkages with the industrial sector of the country, the study investigated the impact of socioeconomic and agronomic settings on wheat yield in wheat-cotton Punjab (Pakistan). District Bahawalnagar stands first regarding its share in the total acreage of agricultural land sown under wheat crop as well as its share in total wheat production in Punjab. By surveying the selected villages of the district, 120 wheat growers were contacted for the collection of data through a questionnaire. The information was recorded through face-to-face interviewing, while data was analyzed by using SPSS® version 20. Amongst the socioeconomic attributes, a farmer’s educational status as literate and landownership status as landless were observed to be positively related to the wheat yield. While amongst the agronomic practices, seed sowing through broadcast method, manual wheat harvesting, poor soil fertility, and the tube-well as the only mode of irrigation were negatively associated with the wheat grain yield. The study concludes that in the context of wheat-cotton Punjab, qualitative attributes of the wheat growers and that of agronomic practices matter in determining wheat yield. The study suggests the need for rural infrastructure (especially, human and irrigational) development in order to bridge the actual and potential yield gaps for wheat crop.","PeriodicalId":22617,"journal":{"name":"The Journal of Agricultural Extension","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88720636","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}
