Effects of Nitrogen and Phosphorus Fertilizers Rate on Yield and Yield Components of Tef at Adola District, Guji Zone, in Southern Ethiopia

Research Article of American Journal of Agricultural Research Effects of Nitrogen and Phosphorus Fertilizers Rate on Yield and Yield Components of Tef at Adola District, Guji Zone, in Southern Ethiopia Yared Tesfaye*, Girma Teshome and Kabna Asefa Oromia Agricultural Research Institute, (OARI) Bore Agricultural Research Center, P.O. Box.21, Guji-Bore, Ethiopia An experiment was conducted at Adola District, Southern Ethiopia to investigate the effect of nitrogen and phosphorus rates on yield and yield components of tef. Four rates of nitrogen (0, 46, 69, 92 kg ha-1) and five rates of phosphorus (0, 23, 46, 69 and 92 kg ha-1) were combined in 4x5 factorial arrangement in randomized complete block design with three replications. Data collected on phenology, growth and yield parameters were analyzed using SAS 9.2 computer software. Analysis of the results revealed that panicle length were highly significant (P<0.01) for the main effect of N. The maximum PL (37.94cm), were recorded at the highest rate of N (92kg ha-1). The interaction of the two fertilizers were also highly significant (P<0.01) for days to 90% maturity (DM) and grain yield (GY) and significantly (P<0.05) affected by number of total tiller (TT),number of productive tiller(NPT)and straw yield (SY).The highest DPE(37.71days) and DM (66.66 days), were obtained from unfertilized (control) treatments. On the other hand, maximum number of total tiller(4.14 per plant),number of productive tiller(3.74 per plant)were recorded from 46/92 kg ha-1 N with 92 kg ha-1 P. Highest straw yield (10676 kg ha-1) and LI (67.41%) were recorded at combined application of 92 kg N with 92 kg P ha-1 while maximum GY (1683kg ha-1) was obtained from combined application of 69 kg N with 69 kg P ha-1. However, the result of economic analysis showed that combined application of 69 kg N and 69 kg N ha-1 gave economic benefit of ...

Empirical Research: Added Value of Agricultural influence on GDP, a Case of China

Research Article of American Journal of Agricultural Research Empirical Research: Added Value of Agricultural influence on GDP, a Case of China Zhiyao Lia and Peiwen Wanga aPoznan University of Life Sciences Agriculture has been the foundation of the national economy since ancient times. With the development of the era, the total agricultural economy has continued to increase. The proportion of the economy is decreasing. This paper analyzes the agricultural value added by analyzing the GDP of China in 2017 (including 31 provinces). After using EViews10SV software to analysis regression, found that there is a positive correlation between agricultural added value and GDP, that is, every percentage point change in agricultural added value, GDP will increase by 0.146543 percentage points, indicating that agriculture has a positive effect on GDP growth.

Use of Communication Media by the Bean Farmers in Selected Areas of Pabna District in Bangladesh

Research Article of American Journal of Agricultural Research Use of Communication Media by the Bean Farmers in Selected Areas of Pabna District in Bangladesh M. S. Islam, M. S. Islam, M. H. Kabir and M. Z. Alam Dept. of Agricultural Extension and Information System, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh. The major purposes of the study were to determine and describe some selected characteristics of the bean farmers, to determine the extent of use of communication media and to identify the factors that influence use of communication media by the bean farmers. The study was conducted in four villages of two unions under Atghoria upazilla of Pabna District. Data were collected from a random sample of 106 bean farmers by using an interview schedule during 15 Dec, 2017 to 15 Jan, 2018. Overwhelming (88.8%) of the farmers had medium to high use of communication media. Step wise multiple regression analysis indicated that knowledge on bean cultivation, training exposure, organizational participation and education had significant positive contribution with their use of communication media by the bean farmers. Overwhelming (86.8%) of bean farmers use medium to high communication media. therefore, it may be said that use of communication media by the bean farmers is a serious issue to be addressed to maximize bean cultivation.

Assessment of socio-economic factors affecting the utilization of manual screw press for gari production in Kwara state, Nigeria

Research Article of American Journal of Agricultural Research Assessment of socio-economic factors affecting the utilization of manual screw press for gari production in Kwara state, Nigeria Adegbola Adetayo Jacob1, Wegh Francis Shagbaor2, Ikwuba Agnes Agbanugo3, Nwafor Solomon Chimela4 1Extension Department, Nigerian Stored Product Research Institute, Nigeria 2 Department of Sociology, Benue State University, Nigeria 3 Department of Sociology, Benue State University, Nigeria 4 Extension Department, National Root Crops Research Institute, Nigeria This study investigated socio-economic determinants of utilization of manual screw press for cassava mash dehydration for gari production in four local government areas across the ADP zones in Kwara state, Nigeria. Using random sampling technique and a semi-structured questionnaire as research instrument, data for the study were collected from a sample of three hundred and eighty four (384) gari processors who use the screw press in the state. Multiple regression analysis show that a correlation (R=0.678) exist between utilization of the screw press and the independent variables which include age, household size, level of education, years of processing experience, extension visits, and income from gari processing. R2 value of 0.460 indicates that about 46% of the variation in utilization was explained by socio-economic variables included in the regression model. Three variables significantly influenced the decision of the respondents to utilize the manual screw press: age, level of experience, and income; the most important predicator being income with a Beta value of 0.699. Conclusively, it was recommended among others that research, extension, and policy makers consider the significant determinants identified in the study seriously if increased utilization is to be achieved by gari processors and others similar to them in the study area and the region.
