Two Factors

The objectives of this research is the effect of straw and range on the yield of  rice (Oryza sativa L). The method of the research use factorial design based on the Randomized Block Design with two factors of treatment. The first factor was straw (without straw (P0), fermented straw (P1) dan straw burned (P2)) and second factor was range (spacing of 25 x 20 cm (J1), spacing of 25 x 25 cm (J2) and spacing of 25 x 30 cm (J3)) and each kombination of treatment three times replicated so that it is obtained 9 trial combinations and 27 trial plots. The result of the research : (1) There was not interaction between straw and range on the yield of rice (Oryza nivara). (2) The highest yield was treatment P1(fermented straw) for all parameters except plant height in 14 hst, penicle length per clump and weight of 1000 grains of dry grains milled. (3) The highest yield was treatment J3 (spacing of 25 x 30 cm) for all parameters except weight of grain per plot dan weight of 1000 grains of dry grains milled.   Key word : straw, range and interaction.

Diallel crossing is a method that is widely used to determine the ability to combine each individual so that it can identify the potential elders to be used in crossbreeding programs to assemble high yielding varieties. This experiment aims to determine the combining power of dialelic crosses of several varieties of rice using the Griffing II method, carried out in the experimental field of the Faculty of Agriculture, Mataram University in Nyiur Lembang Village, Narmada District, West Lombok Regency, from February to July 2019. This experiment uses the method experiments carried out in the field. The materials used in this experiment were four parents, namely IPB 3S variety, Situ Patenggang variety, Inpari 32 and G11 strain and the phenotype of the cross between the four parents. The experimental results showed that the effects of general affinity and special affinity for all observed characters (plant height, number of productive tillers, number of non-productive tillers, panicle length, number of filled grain, number of empty grain and weight of 100 grains) were significantly different, except on the effect of general affinity for the number of non-productive tillers showed no significant difference. The results of the combined power analysis of the four elders were positive, so it can be said that the four elders would get good results when crossed with a number of other genotypes.
