To determine the optimal ploughing depth and to make tillage simpler and less costly, but also taking account of edaphic and climatic conditions as well as biological and agrotechnical requirements of crops grown, long-term investigations (1994-2009) have been carried out on Stagnic Luvisol of sloping terrains in central Croatia near Daruvar. Th e paper presents the results relating to plant de...

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...

This study integrates a biophysical model with a county-specific economic analysis of breakeven prices of bioenergy crop production to assess the biophysical and economic potential of biofuel production in the Midwestern United States. The bioenergy crops considered in this study include a genotype of Miscanthus, Miscanthus giganteus, and the Cave-in-Rock breed of switchgrass (Panicum virgatum)...

The use of non-destructive devices like Delta-T-LeafAreaMeter and Canegro Models can help farmers to manage their cane crops and have an understanding of the importance of measurement of physiological parameters so as to maximize cane and sugar yields. This study was conducted on sandy clay loams of the lithosol group under the Zimbabwe soil classification system at The Zimbabwe Sugar Associati...
