| A field trial was conducted to evaluate the application effects of controlled release nitrogen fertilizers on pepper. The
results indicated that application of controlled release nitrogen fertilizer showed positive effects in yield increase, quality improvement and nitrogen use efficiency under the same nutrients. Compared with common urea, application of controlled release nitrogen fertilizer could increase yield, Vc content, fruit weight, fruit length and nitrogen use efficiency by 10.1%~11.8%, 7.4%~8.6%, 2.5%~4.6%, 4.8%~6.8%, and 10.1~12.4 percentage points respectively. The controlled release nutrient fertilizer (No. 2) was the most effective among the fertilizers in field trial, suggesting that it may have potential as a commercial fertilizer. |
