to assess the effect of non chemical management of weed control on forage sorghum (sorghum bicolor) a field study was conducted in varamin, iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (w1= one time cultivation at 3-leaf stage using a duck foot cultivator, w2= two times cultivation at 3 and 5-...

The purpose of this research is to study the effect deep loosening row spacings on physical properties soil and yield organic potatoes. Two variants cultivation were used in spacings: usual 25 cm deep. was carried out with a row-crop chisel cultivator. Its design developed at institute. Analysis data obtained as result experimental studies showed that had positive compaction both inter-row widt...

Typically, low-pressure sprayers are used to uniformly apply pre- and post-emergent herbicides to control weeds in crop rows. An innovative machine for weed control in inter-row and intra-row areas, with a unique combination of inter-row cultivation tooling and intra-row band spraying for six rows and an electro-hydraulic side-shift frame controlled by a GPS system, was developed and evaluated....

Tillage erosion is a potential contributor to the total soil erosion occurring within cultivated fields. No study has been carried out on tillage erosion associated with cereal-based production systems, which are the predominant form of crop production in the Canadian Prairies. Previous tillage translocation studies have focused on primary tillage implements (i.e. mouldboard and chisel ploughs)...
