Abstract
If in the control-green manure without crop experiment variants, the plant height was
80.6-79.1 cm, the yield horn was 14.2-14.1 pieces, the average joint spacing of the main
stem was 4.1-4.3 cm, the main stem thickness was 1.78-1.76 cm, when green manure crops
were applied, the agronomic soil properties and characteristics were positive for the plant,
coordinated the cotton growth and development, the plants were found to be relatively
vigorous and healthy growing and developing. This pattern was repeated in all
experimental years, and the data were observed in an analogous manner.
When green manure crops were applied in summer and autumn, the cotton
verticillium wilt incidence was reduced. This condition was observed throughout the
growth period. This, barley acted like rapeseed. For example, in the summer control-green
manure cropless variant, 4.9% of cotton plants were infected with verticillium wilt on July
15, 9.3% on August 1, and 13.3% on August 15, pea variant 4.5; 8.1; 12.4%, 3.8; 7.2;
11.8% in the chick-pea variant, respectively, raps variant 2.4; 5.1; 8.3%, barley variant was
2.7; 5.3; 8.9%.
In particular, in the fall, the control-green manure without crop variant was 5.8%
on July 15, 10.2% on August 1, and 14.8% on August 15, while the pea variant was 5.28.9;
13.1%, respectively; chick-pea variant was 4.8; 8.6; 12.1%, raps variant was 2.6; 5.3; 8.6%,
and 3.0; 5.8; 9.3% in the barley variant.
In the control-green manure cropless experiment variant, the yield was 35.1s/ha,
while in the green manure management variant 5.5-8.6 s/ha was obtained. In the
experiment, the highest yield (43.7 s/ha) and the most reliable additional yield (8.6 s/ha)
were obtained in the raps planted variant as a green manure crop, 42.8; 40.8 and 40.6 s/ha
yields were observed in barley, chick-pea and pea variants planted as green manure crops,
respectively.
