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...

Crop depends on its canopy to intercept solar radiation to drive both assimilation and water, nutrient absorption for its growth. Field experiments, involving three sowing time and three sowing rate, were conducted at Luancheng Station to investigate the effects of canopy size and development on crop growth and radiation use efficiency (RUE) of winter wheat during 2009/2010 and 2010/2011 gr...
