Quantitative analysis of production through evaluation of inputs consumption quantity is of main principles in agricultural policies, which is followed by increasing in production through optimal use of resources. This study has been conducted to estimate different types of production functions in mechanized farms of broiler chicks located in Gorgan city. Cross-section survey data were gathered...
This study aimed to investigate the cost-benefit of sesame production per hectare under improved and (traditional production) farmer's practice. The primary data were collected from farmers who cultivate both traditional (plot with agronomic technologies on one side practice other side) selected randomly participants households cluster-based large scale demonstration during 2019 in kafta-humera...
Predicting the maintenance and management costs and replacement age of tractors in agricultural mechanized units, is important from several points. So, doing a timely agricultural operations, more accurate measure of the amount of income including the cost of these items , determining the useful life of old tractors , replacement age, cost of the process changes and the possibility of examinin...
Mechanized harvesting of crops is very important in the field agricultural engineering, then brush a common way. The comb device divided into four types: tooth type, roller spring finger belt and rod type. picking rate breakage are indexes to evaluate effect devices. How improve reduce damage great significance popularization To rate, design teeth should conform growth characteristics crops. In...
To solve the problems of a large number clods remaining in potatoes after mechanized harvesting northern heavy clay soil planting areas China and requiring much labor to separate from potatoes, which leads workload, inefficiency low cleaning rate, an RGB-D-based Mask R-CNN dynamic potato identification model is established by using acquired RBG-D image data untreated harvesting, method presente...
Two optimization problems are considered: Harvesting from a structured population with maximal gain subject to the condition of non-extinction, and vaccinating a population with prescribed reduction of the reproduction number of the disease at minimal costs. It is shown that these problems have a similar structure and can be treated by the same mathematical approach. The optimal solutions have ...
Katoul is a new soybeam cultivar originated from a genotype named D.P.X.3589 imported from the United States of American in 1990. This genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in Gorgan and other research stations during 1999-2002. The mean seed yield of D.P.X.3589 in all these experiments was 3333 kgha-1 ...
Growers need reliable information on costs and returns they can expect for a cider apple ( Malus × domestica ) orchard suitable mechanization because specialty apples only be used making cider, are expected to lower than fresh table apples. This study estimates the costs, returns, net profit that growers may realize by planting in either freestanding or tall spindle system use mechanical harves...
