EFFECTIVENESS UNDER CONDITION OF NPK LEVELS ON DISTRIBUTION OF 32P, 14C AND GRAIN YIELD OF ODOROUS RICE AND DARK PERICARP RICE (ENDICA RICE)

Abstract:

Under conditions of various levels of N,P,K with 0,0,0, 2,2,2, 4,4,4 and 4,2,2, 2,4,2, 2,2,4 grams, supplied in soil of per pot (vol. 10 L.) before transplanting, the tiller number, grain yield and ³²P, ¹⁴C distribution in three rice varieties "Zhu-Xiang-ZhantZXZ),"Hei-You-Zhan(H YZ) and common rice cultivar "Shuang - GUI-36"(SG36) were studied. Odorous rice "ZXZ"had more tiller number at every level of NPK and its roots absorbed more ³²P which concentrated in tillers under the conditions of high, middle le...
