Abstract
In a glasshouse pot experiment, the response of two paddy varieties were studied on Tuaran ( Entisol ) and Papar ( Ultisol ) soil at five different N fertilisation rates. The response of these two popular varieties amongst local farmer which, is currently subsidised by the government was measured in terms of N percentage in plant, ROB value and dry weight as well as the interaction of applied FR with the former variables. Two replicates per variety gave a total number of forty - eight (48) pots. Nitrogen was applied at 0, 50, 100, 150, 200 and 300 kg ha-1 at three split applications; before tillering, tillering and stem elongation stage. This experiment was desired to obtain optimum and maximum fertilisation rate and also to determine the suitability of a variety grown on every soil. Its' purpose is also to investigate the relationship between plant greenness (ROB) against fertilisation rate. Maximum fertilisation rate was recorded at 159.5 kg ha-I for MR159PR and 220.7 kg ha-1 for MR159 on Tuaran soil. Optimal fertilisation rate is suggested at 124.45 kg ha-1 for MR159_PR and MR159_TN at 78.16 kg ha-1 . Result also showed that ROB increases with fertilisation rate until 200 kg ha-1 . Only variety MR159 responded significantly in this experiment, suggesting that it is suitable to be grown on both soil type.
