The Influence of Double Crops and Intercrops on Soil Fertility

Zukhriddin Muminovich Jumaboyev

Abstract: In short double cropping systems 2: 1, the cultivation of soybean as a second crop after winter wheat, and after soybean the cultivation of intercrops in autumn such as oats, green peas and rye in combination, and plowing of land with crop organic residues (roots and stubbles) after harvesting them in spring have resulted in increasing of humus and nitrogen in soil, the mass of soil and the capability of water permeability, and also allowed to easy absorption of phosphorous compounds which were difficult to absorb due to decomposition of this organic residue. As a result, the yield of cotton planted after them was increased.
