a new mechanical cultivator was proposed for mechanical weeding in part one. the precise point method was used to geometric design of this new cultivator. the aim of this research is selecting the suitable mechanism of the studied mechanisms in part one. the velocity and acceleration of links (kinematic) is the base of dynamic analysis of the systems. the variation of velocity, acceleration and...

India clocking the highest ever agricultural exporter of over $50 billion in Financial Year 22, basmati rice, one country’s oldest anchors farm exports, seems to have fallen off radar screen. For third consecutive year, rice exports saw a fall previous year value. In 2021-22, exported worth $3.53 billion, lowest since 2019-20. The reason for decreasing exporting is analyzed this study at Panjab...

The soil preparation is a plan according to which crops are grown on individual field preparations of farm during given period time with object obtaining minimizes cost and higher from each crop without imparting the fertility. A can utilize input other technology available cultivator, ploughing, levelling etc. should be adopted by farmer. Thus, levelling, land scraping banding related most pro...

Curved tubes of non-circular cross section are widely used in various fields technology. The change the planned operating modes technological processes is associated with wear executing mechanisms, which caused by unstable frequencies and amplitudes oscillations. Thus, issue determining oscillation parameters these elements becomes more significant. technique results tests for stresses, displac...

Converting the power units of existing transport and transportation vehicles to NGV fuel requires not only creation necessary infrastructure for trouble-free operation such machinery, but also significant investments initial installation relevant equipment. Various evaluation criteria are used justify feasibility a conversion. The authors have studied conversion diesel engine D-243 tractor MTZ-...

A challenge for African countries is how to integrate new sources of knowledge on plant genetics with knowledge from farmer practice to help improve food security. This paper considers the knowledge content of farmer seed systems in the light of a distinction drawn in artificial intelligence research between supervised and unsupervised learning. Supervised learning applied to seed systems perfo...
