Proceedings a/the 9th International Symposium on Buckwheat, Prague 2004 Alternative Fertilizer for Buckwheat Z.I.Glazova

Joint implementation of grinded straw of cereal forecrop and phytomass of afterharvest green manuring crops (white mustard, vetch, lupine) is expedient as phytoorganic manure for buckwheat. Its implementation provides grain yield supply 23-33%, reduces energy expenditures 1,1-1.47 times, The major direction in a contemporary agrarian science is development and introduction in technology of cultivation of agricultural crops of ecologically safe, ' low-cost adapters, alternative to traditional, intensive. This work is especially necessary for buckwheat which crop has high nutritive and dietary qualities. One of principle questions of biologization of technologic process of cultivation of buckwheat is particulate exclusion or changing of fertilizers on phytoorganic (straw and a green material of intermediate crops). Value of straw as organic fertilizer (1-3) is well-known. Positive effect of green manure on a soil fertility and productivity of agricultural crops, marked even in the middle of the 19th century, has found acknowledging in numerous researches nowadays (4-6). There are also separate publications about utilization of afterharvest green manuring under groat crops in which it was registered the fertilizing significance of biomass of winter crops brought in to soil in spring (7-8). However some explorers registered, that the organic mass of only grain crops at decomposition secretes into soil substances of phenolic nature, that rises its toxicity and can result in oppression of initial growth ofplants (9-10). Therefore selection of biologically various crops for afterharvest is necessary for green manuring, giving a good harvest of green material, providing to soil a smaller toxicity, and to plants of buckwheat the best security nutrients. Studying of this question also has formed the basis for carrying out of similar researches by us
