Effects of different new fertilizer application on yield and quality of rice

Abstract

Abstract:

The high-yielding hybrid rice cultivars of Yongyou 1540 was adopted as the test material in this study. Two types of fertilizers, resin-coated slow-release fertilizer (Maoshi) and stabilized fertilizer (Shikefeng), were selected. Three different nitrogen fertilizer allocation ratios were set. The results showed that compared with the conventional fertilization, the 667 m²yield of rice was increased by 21.91%, reaching 527.63 kg, when the slow-release fertilizer (Maoshi) was applied with a ratio of 5:2:3 for base fertilizer, tillering fertilizer, and panicle fertilizer, and it did not affect the grain quality. Compared with the conventional fertilization, applying stabilized fertilizer (Shikefeng) with a ratio of 5:2:3 for base fertilizer, tillering fertilizer, and panicle fertilizer increased rice yield and nitrogen use efficiency without affecting grain quality. The results indicate that optimizing the appication of slow-release fertilizer was beneficial to improve soil fertility, promote nitrogen utilization, and significantly increase rice yield by increasing the number of panicles.

Key words: new fertilizer, nitrogen application, rice, yield, quality
