Therefore, in any river basin, it is very important to calculate the hydrological cycle parameters such as evaporation, infiltration, and runoff, and to determine the level of influence of natural factors affecting this process. In this study, In Goksu Basin, it is aimed to determine the effect levels of natural criteria such as lithology, soil, land use/cover, soil cover (ndvı), slope, aspect, on infiltration and runoff. In the hydrological model developed for this purpose, natural criteria, digitization formula, ArcGIS based analytical hierarchy (AHP) model program were processed and their effect levels were revealed. According to this result, infiltration and runoff values are close to each other; Lithology 57.1%, soil 12.9%, land use/soil cover 18.4%, slope and aspect between 5.1% and 6.4% were determined. As a result of the model application, the total infiltration and flow amounts of 407.1 mm calculated with the converted real infiltration and runoff coefficients were correlated with the current height of 429.2 mm. It was found to be quite successful at 0.95.","PeriodicalId":34255,"journal":{"name":"Indonesian Journal of Agricultural Research","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73470207","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 obtained data was analyzed using the two-step methodology of Engel and Granger, Granger causality, and the impulse response function. The result showed evidence of co-integration between fishery GDP growth rate and the economic phenomena. Also, the GDP growth rate of the sector is efficient as it established a long-run equilibrium but the slow pace at which it corrects the distortion in its equilibrium makes the state of the efficiency to be a weak one. Furthermore, the fishery’s GDP growth rate is affected by high inflationary trend, red-tapism, and poor credit utilization. Empirical evidences showed that unexpected local shocks on the economic phenomenon will have a transitory effect on FGDP growth rate, thus will die-out over time. It was observed that the effect of the internal mechanism on the growth rate is passive while the external system effect is active on the growth rate. Therefore, the study recommends the need for policy strengthening by the concerned stakeholders viz: tiding of inflationary trend, red-tapism, and ineffective credit utilization, thus enhancing the growth of the sector.","PeriodicalId":34255,"journal":{"name":"Indonesian Journal of Agricultural Research","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91344254","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 multiplication and domestication of these species remains the only way to save them from extinction, our study is within the framework of propagation by cuttings of odorous verbena (Aloysia citrodora). In fact, some parameters influencing the success of cuttings have been studied, namely the nature of the substrate, the effect of certain rooting products and the position of the cutting in relation to the mother plant (basal or apical), the tests were carried out in a tunnel greenhouse at the ibn tofail university, faculty of sciences kenitra, Morroco. Out of 144 trials, the success rate of cuttings according to the type of substrate was 91.66%, 75% and 83.33% respectively for substrates S1 (soil only), S2 (1/2 sand and 1/2 compost) and S3 (1/3 soil; 1/3 compost and 1/3 peat). For the three products, we didn’t make combinations. but we followed the effect of each product alone, For the treatment effect, 77%, 0% and 69% respectively were obtained for Product 1 (auxin), Product 2 (based on mineral matter and amino acids) and Product 3 (seaweed extract). With regard to the position of the cutting, high percentages were obtained for cuttings from the basal position.","PeriodicalId":34255,"journal":{"name":"Indonesian Journal of Agricultural Research","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88710061","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 study examined the technical efficiency of USAID-MARKETS II project participant and non-participant rice farming households in Ebonyi State, Nigeria. A multi-stage sampling procedure was employed to select 491 rice farming households which comprise 239 participants, and 252 non- participants. Primary source of data were collected with the use of a structured interview questionnaire and field participation. Data were analyzed using mean, standard deviation, and percentage, Z statistic, and stochastic frontier Model. The result from the study, reveals that the USAID-MARKETS II project participants were 92% technical efficient while USAID-MARKETS II project non-participants were 91% technical efficient. The result further reveals that a significant difference exist between the participants’ technical efficiency and that of non-participants of USAID-MARKETS II project. Household size and education were the vital factors that improved technical efficiency of the rice farmers. Therefore, Ebonyi rice farmers should be adequately trained on modern rice production techniques by the government agency, Agricultural Development Programme (ADP) and non-governmental agencies. Also, adequate extension services should be provided to the farmers by the ADP for proper information dissemination.","PeriodicalId":34255,"journal":{"name":"Indonesian Journal of Agricultural Research","volume":"28 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78107914","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}

This research was conducted in three villages in Kumpeh, namely Mekarsari, Betung, and Seponjen. Samples consisted of 63 smallholders and were taken using the Simple Random Sampling method. The data were analyzed descriptively and subjected to statistical tests of multiple linear regression analysis. The results show an R2 of 0.888, indicating that the model variables can explain 88.8 percent of the oil palm production variation. The F test resulted in a value of 115.299, showing that the production variables together have a real effect on production. Partially, the independent variables that have a real and significant impact on oil palm production at a realistic level (α) of 5 percent are land area, fertilizer, and pesticides.
