The influence of different sowing dates on the production of green biomass of green manure

In the experiment, when different green manure crops like peas, chick peas, rape and barley were planted as green manure in grain-free fields were sown in the summer on July 10, July 20, July 30 and in autumn on October 10, October 20, October 30, as well as in summer (July 10), high green biomass yield was 14.54-52.92 t/ha relative green biomass yield was observed on July 20 and green biomass yield constituted 14,10-50,73t/ha. When different green manure crops peas, chick peas and rape and barley planted on October 10,20,30 was observed to be high between the rows of cotton in autumn, the productive yield was high sown on October 10 and constituted 6,44-22,41 t/ha and the yield on October 20 was after then. In this case green biomass equaled to 6,04-21,91 t/ha.
