Dry direct seeding of rice (DDSR) is being increasingly used in water-scarce areas across Asia. When drought occurs, deep sowing may enable germinating seeds to utilize the residual moisture below surface. Our objective was examine effects different depths on DDSR crop growth. Two yield experiments, one Philippines and other Japan, were established rainfed lowlands, but did not occur. Across at...

one of the main problems in the mass production of pepper transplant is the stickiness of seed coat to the cotyledony leaves that can lead to no emergence or having poor emergence of pepper seedlings. therefore, in order to evaluate the effects of different sowing depths and soil compactions on emergence and early seedlings growth of pepper, a greenhouse experiment was conducted in the faculty ...

Existing devices for dry direct-seeded rice with film mulching in northern China have limitations such as imprecise sowing, unadjustable sowing depth, and seeding device blocking. In this regard, study proposes a combined method of ‘mini shovel + telescopic pipe’ mulching. A precision seeder was developed through theoretical calculations, discrete element modelling (DEM) simulations, field expe...

Annually, 200 ha of Agh Ghala rangelands in Golestan, Iran are under Alkaligrass Puccinella distans''s cultivation but the failure in the identification of appropriate sites for seed sowing may result in high costs of cultivation. The current study aims to reduce such costs through the examination of apt sites to grow P. distans in northern rangelands of Agh Ghala Golestan, Iran. Because of the...

Machinery for sowing wheat directly into rice residues has become more common in the rice-wheat systems of the north-west Indo-Gangetic Plains of South Asia, with increasing numbers of farmers now potentially able to access the benefits of residue retention. However, surface residue retention affects soil water and temperature dynamics, thus the optimum sowing date and irrigation management for...

Aspen produces large numbers of seeds, even though it mainly reproduces asexually with root suckers. The aim of this study was to find out how different moisture conditions affect emergence and survival of Populus tremula L. seedlings. This was studied with a sowing experiment (totally randomized factorial design). There were altogether 10 blocks, each containing 16 microsites and three treatme...

introduction red beans (phaseolus vulgaris l.) with 22-25 % protein and 50-60 % carbohydrates are one of the most important legumes in the world, particularly in some developing countries. it is one of the major sources of vegetable protein. with regard to increasing population and increasing the need of protein, the use of plant resources like red bean with a large amount of protein is growing...
