this study examined suitable mechanized methods to seed rice in dry-bed conditions using dried seeds and determined the most suitable varieties for each method. the experimental design was strip-plots in a randomized complete block design with two factors (seeding methods and rice varieties) and three replications. the testing took place during 2003-2004 at the shavour agricultural research sta...

tillage and press wheel weight play an important role in seedling emergence, crop establishment and growth. an optimal combination of tillage implements and suitable press wheel weights should increase grain yield. this study investigated the effect of tillage systems and press wheel weights on dry land wheat (triticum aestivum l.) seedling emergence and grain yields in izeh, khuzestan province...

This work was aimed at assessing whether in silage maize it is possible to replace precisionplanting with a volumetric seeding in the perspective of developing hybrid machines to strip tilland sow both high density crops like winter cereals and low density crops like maize. This inorder to reduce the number of machines in the farm, simplify logistics and reduce amortizationcosts. Two experiment...

In direct seeding systems, soil strength variability and crop residues increase the difficulty of seeding operation. Especially when trying to achieve uniform seeding depth that will result in reliable seed germination and plant emergence. An advanced improvement has been accomplished using direct seeding systems. However, some problems still exist in soil-machine interaction due to various rea...

The article discusses a method for planting seeds in stony soil and device its implementation. It has been established that the quality of seed placement significantly depends on formation earthy layer at depth placement. A is proposed soil, which includes cutting off upper with simultaneous separation, fine-grained layers from it laying them alternately top each other, forming grooves, bottom ...

Reforestation can be carried out using natural regeneration or artificial regeneration. There are vari-ous methods for the regeneration, including manual planting, mechanical planting and aerial/or ground seeding. This article aimed to review current reports on productivity of provide a summary rates machines. According review’s results, may vary from 143 475 seedlings per productive ...
