Usually large numbers of measurements are required to describe spatial variability of soil resistance but GIS technology with interpolations methods make it possible to estimate data from unsampled locations. In this paper cone index (CI) measurements were made in two occasions in 2.88 ha fi eld in central Croatia to present soil condition. A commonly used tillage operation consists of ploughin...

to evaluate the effect of cover crops, tillage systems and nitrogen (n) application rates on yield of forage sorghum (cv. kfs3), a factorial–spilt plot arrangement based on randomized complete block design with four replications was carried out at the research farms college of agriculture and natural resources, university of tehran, karaj, during the growing seasons of years 2005 and 2006. comb...

In Mexico, the continuous increase in prices of fossil fuels and agricultural fertilizers has led to a reduction area planted with crops, specifically basic grains. This situation caused substantial ecological economic losses national deficit production grains, which aggravated social producers. Faced these growth limitations, it is important generate new practices innovations that contribute r...

Syringopais temperatella Led. (Lep., Scythrididae) is a serious threat of barley and wheat in Jordan as it causes great loss crop. There growing interest the development innovative control strategies aiming to minimize environmental impact pest management improve safety agro-food chain. However, little attention has been paid on use cultural methods against pest, accordingly, this study aimed a...

The purpose of research on alternative variants soil tillage systems related to fertilization, vegetal residues, and cover crops, in the case maize crop, is elaborate promote certain integrated technologies conservation agriculture. This paper presents results a study conducted Transylvanian Plain during 2019–2021, regarding influence technological climatic factors yield quality maize. objectiv...

During the last decade in Mexico, profitability of basic grain crops has decreased considerably due to low productivity caused by unfavorable soil and climatic conditions, which are aggravated climate change. In addition, variability international economic environment rise fertilizer fuel prices factors that seriously affect production these food products. this context, it is important generate...

The famous empirical model for the horizontal force estimation of farm implements was issued by American Society Agricultural Biological Engineers (ASABE). It relies on information soil texture through its adjustment parameter, which is called Fi -parameter. Fi-parameter not measurable, and geometry plow machine parameter values are measurable; however, tillage speed, implement width, depth mea...
