The Influence of Using Different Amendments on the Growth and Yields of the Crop
Abstract: In order to study the effects of soil amendments on the growth and development of crops in arid regions, the experiment was conducted in different years by using different kinds of soil amend-ments. The single factor randomized block design was used to study the growth and yield of potato and oil sunflower under different amendments. The results showed that different modifiers had different effects on the growth and development of crops. In the experiment of potato, type II had the best effect, and the yield (1163.05 ± 191.14 kg) was highest, and the plant height and leaf area were also promoted. In the experiment of oil sunflower, the improvement effect of type I and type II was significantly better than that of the modified agent and bio organic fertilizer, and they can significantly affect the stem diameter (Ningda modifier type II 33.13 mm and Ningda modifier type I 29.82 mm), dry matter (Ningda modifier type II 1581.398 kg and Ningda modifier type I 1472.305 kg), leaf area index (Ningda modifier type II 6.72 and Ningda modifier type I 6.18 was most suitable), and the results also showed that the highest yield was the best type I and II of modified agent, and Ningda modifier type I (255.57 ± 25 .93 kg) was highest. The results showed that the application of amendments had a positive effect on the growth and yield of oil sunflower and potato, and the best effect was found in the type I and the type II modi- fier.
