In-Depth Information
Alfalfa grass develops a vigorous root system, securing yields of fodder and seeds
for 6-8 years with simultaneous increase of soil fertility due to legume grasses' capac-
ity to accumulate biological nitrogen.
Mixture of zeolite-containing clay alanite with molybdenum-acid ammonium
leads to normalization of soil solution and decreases acidity in seedbed. Thus, joint
treatment by molybdenum-acid ammonium and alanite is necessary for the develop-
ment of alfalfa plants. Zeolite-containing clay prolongs the action of the mixture. It
slowly releases elements contained in the mixture.
The above-mentioned agro-technical process—treatment of seeds before sowing
in the water solution of ragweed and enveloping of wet seeds by tubercle bacteria
from the root system of alfalfa—has signifi cant importance. This process permits to
increase germination rate of seeds and energy of sprouting as well as to decrease seeds'
hardness.
Ragweed (
Ambrosia artemisiifolia
L.) contains the complex of chemical substanc-
es, including essential oil, glycosides, macro-elements, which stimulate seed germina-
tion. Unlike other phyto-stimulators (nettle, wormwood, etc.), ragweed grows every-
where and is often found as a weed in various crops.
Results of the experiment revealed that germination rate of alfalfa seeds grows
from 72 percent (control—soaking in the water) to 92 percent in the optimal way of
ragweed treatment. At the same time, hardness of seeds decreased from 13 to 8 percent
in the optimal variant. As a result, erosion processes on slope lands weaken 2-3 times.
3.4 CONCLUSIONS
1. Placement of legume grasses after winter cereals secures increase of seed
yield of legume grasses.
2. Treatment of seeds before sowing by mixture of zeolite-containing clay and
molybdenum-acid ammonium by ragweed solution facilitates decrease of
hardness of legume grasses' seeds.
3. Additional fertilizing of seed grass by water solution of ragweed increase seed
yield of clover and alfalfa on 18-25 percent.
4. Using natural resources (zeolite-containing clay, weed plant ragweed), it is
possible without additional costs to increase seed yield on slope lands and
weaken erosion processes 2-3 times.
