Abstract:

La culture du riz joue un rôle décisif dans les moyens d'existence des producteurs. La production rizicole rencontre des difficultés liées aux coûts de fertilisation. L’étude avait pour objectif d’évaluer les performances économiques et financières des biodéchets et des fertilisants inorganiques en riziculture pluviale stricte. L’évaluation est faite suivante deux démarches : la première consiste à calculer et à comparer les indicateurs de performance, tandis que la deuxième repose sur une matrice de corrélation afin d’identifier les relations entre les indicateurs de performances économiques

La distribution et la commercialisation du riz en Côte d’Ivoire ont été assurées par les structures étatiques telles que l’ex-SODERIZ1de 1960 jusqu’aux années 1980. Il s’agissait pour l’État de maitriser les circuits de distribution, de commercialisation, ainsi que le prix du riz. Après la crise économique des années 1970 qui a occasionné la dissolution de la SODERIZ en 1977, des acteurs du secteur privé se sont lancés dans l’importation et la commercialisation du riz. Toutefois, concernant le riz local, la commercialisation est assurée par les acteurs locaux eux-mêmes. Le présent article port

Abstract:

The conventional way to husk rice is to pass it between two rubber rollers that are rotating with a surface speed differential. The resulting normal pressure and shear stress causes the husk to be peeled away from the kernel. The process is suited to high-rice flow rates, but is energy intensive and can result in considerable wear to the surfaces of the rollers. The operating parameters for machines of this design are usually determined and set empirically. In this article, some experiments and calculations had been carried out in order to explore the mechanisms involved in husking rice grains

Abstract:

Determination of accurate paddy field surface profile has great importance to designing the paddy tractor suspension system. With this aim, a new test rig has been designed and developed to measure paddy field surface profiles using static level method (sampled interval of 200mm). The data were analyzed through Matlab/Simulink software to obtain power spectral densities (0.05-3.5c/m) of the measured profiles on a log-log scale and it was found that the amplitude variation of the power spectral density (PSD) at low spatial frequency was higher than at high spatial frequency whereas the undulati

The agriculture industry is the most important industry for society as it serves the most important need of life. But the plant diseases in agriculture lead to a decrease in productivity and hence it is very important to prevent, detect, and get rid of the diseases. Image processing and deep learning are nowadays the buzzwords in the IT industry and their applications in the agriculture industry can enhance decision making in various aspects of the agriculture industry. Paddy crop is one of the most demanding crops especially in South Asia. This paper proposes a predictive model using CNN for

Abstract:

Agriculture is the most important sector in the Indian Economy and gives contribution in the form of agricultural productivity. To increase the agricultural productivity, precise and on-time detection of crop diseases and pest is needed. Most of the times, farmers fail to take the necessary steps even if they may have been able to identify the problem. Moreover, in some rural areas farmers cannot get rid of these problems because they do not have proper knowledge or education on how to do so. Most of the cases involve leaf diseases which are not recognized properly, and farmers end up using in

AbstractThere are many applications, such as fruits, paddy rice drying, and so on, where air heaters are comprehensively used. The provision of ribs in solar energy‐based air heaters has been accredited to be a beneficial approach for escalating its thermal performance. This investigation reveals the performance evaluation of a rectangular sectioned solar air heater duct placed with the curved type of ribs organized in noncontinuous and truncation patterns. Influence of variation of pitch ratio (4.0–12.0), block‐age ratio (0.06–0.1), the ratio of rib height to the radius of rib curvature (0.75

Paddy field, the paddy planted area, is a very important land since it produces staple food – rice. Nevertheless, the contradictory condition occurs when agricultural land converted into non-agricultural land. Agricultural land that is not protected is proned to the land conversion, especially in urban areas or the growing city. The study aimed to figure out the strategies for protecting paddy field by identifying the spatial pattern of social quality of paddy field farmers. the research methodology used mixed concurent method by using qualitative and quantitative data and it was analized by c

Estuarine wetlands provide an especially ecological home for various flora and fauna, with fragile ecological structures and functions easily affected by the external disturbances of both anthropogenic and natural activities. Recently, wetlands (such as water and marsh) of the Bohai Rim region have been, and continue to be, lost or altered under the influence of both local urbanization and economic development. There is an increasing need for crucial essential wetland change detection as one of the most critical works for relevant research. The paper’s objective focuses on detecting the annual
