Four paddy threshers; namely power operated thresher-cum-winnower, power-tiller operated thresher, tractor operated thresher and tractor operated half feed thresher were evaluated with three varieties of paddy at three levels of grain moisture content. Their performances were compared with conventional methods i.e. hand beating and bullock treading. Threshers were evaluated with respect to output capacity, threshing efficiency, cleaning efficiency and grain losses. It was found that with increase in grain moisture content, the output capacity, the percentage of un-threshed grain and total grain losses increased while the percentage of grain breakage decreased for all the threshing methods used. Maximum output capacity was observed in case of tractor operated paddy thresher while it was minimum in case of conventional hand beating.
Sesame (Sesamum indicum L.) is one of the important oilseed crop which is widely cultivated in tropical and subtropical areas of Asia, Africa and South America since ancient times. Present study was carried out to evaluate the phenotypic variability in sesame genotypes from different parts of West Bengal and some major sesame growing states of India along with eight genotypes from USA, Bulgaria and Bangladesh, using 12 quantitative traits. Genotypes like CUMS 17, CUHY 57, MT 75, Atghara, RT 351 were to some extend better performed than the check variety TKG 22 and GT 10 regarding yield and other yield attributing traits in both locations (Ranaghat and Baruipur) At both genotypic and phenotypic level, seed yield per plant showed significant positive correlations with 1000 seed weight, seeds per capsule and capsules per plant and significant negative correlation with days to maturity, which suggests that seed production is mostly depends on these mentioned characters whereas early maturity depends on early flowering. Highest oil content was observed in TKG-352(53.13) followed by EC 96, CUMS 17, RT 351, Shekhar, GT 10 those recorded > 48% oil contents. Three genotypes namely AT 306, RT 351 and HT 2 recorded higher value of soluble protein content of > 17 %. In cluster analysis genotypes grouped into various clusters exposed that there was no relationship between geographical distribution and genetic diversity. These results have an important suggestion for sesame genotypes agro-morphological characterization, evaluation and improvement in future.
The purpose of this study was to determine the effects of use of petroleum diesel (D100) and biodiesel (B100) fuel blends compared to pure diesel on the engine performances of a farm tractor with a tillage implement in field. The experiments were conducted on a tractor engine using a blend of biodiesel and petroleum diesel in the ratio of 20, 50, 80 and 100 % of biodiesel in the blends. The tractor performed with each blend doing standard tillage in field spots of 2500 m2 with three repetitions. The specific fuel consumption improved as percentage of biodiesel increased in the blend, obtaining a minimum of 0.0966 (L/kWh) for Biodiesel Alone B (100). While the energy efficiency in the usage of fuel by the tractor decreased as the percentage of biodiesel in the blend was increased, showing a maximum value of 104.9 % for a 20 % of Biodiesel in the blend, with respect to the Diesel fuel (D100), whose efficiency was considered being 100 % as a referential value.
The purpose of this study is to analyze the problem of management of natural- anthropogenic complexes of rural territories in the context of the post-non-classical type of scientific rationality at the philosophical and methodological levels. The problem of management of natural-anthropogenic complexes is considered and analyzed in the article at the philosophical level in the context of the humanistic interpretation of philosophical constructivism. At the methodological level, the management of natural-anthropogenic complexes of rural territories is considered in the basic paradigm “subject – metasubject”, in which a natural-anthropogenic complex is presented in the form of a self-developing environment, an integrated study of which is possible only using an interdisciplinary approach.
Irrigation plays an imperative role in agriculture production and productivity growth. The present study is an attempt to realize the goal of assessing impact of small scale irrigation project on rural household’s income. It was conducted on Kashu irrigation project located at Shey Bench district, Southwest Ethiopia. A Cross-sectional data was collected from 264 households (128 irrigation users & 136 non-irrigation users) of Bata Kebele of the district for estimating the results using econometric models. To this end, several variables were used to determine household’s probability of participation in irrigation use. The decision to participate in irrigation was significantly influenced by irrigation experiences, frequency of extension contact, access to credit services, distance to nearest market and training access. The estimated results via propensity score matching (PSM) estimation technique indicated that the average income of irrigation user’s household is significantly higher than nonusers by birr 2460.70 (US dollar 70.40) per year. Our analysis also shows that the Radius (Caliper) matching with a bandwidth of 0.25 is considered as best estimator for quality matches based on the criteria of (balancing test=12, pseudo-R2 = 0.065 and matched sample size=226). Based on these findings, it is recommended that strong markets infrastructure; better extension service, effective farm training system may have the potential to attract the farmers in to the irrigation project.
