Evaluation of Agronomical Characters of 15 Genotypes of Local Upland Rice Breeding under Organic and Conventional Farming Methods and Their Adaptability to Aluminium

Abstract

Rice is one of strategic foods in Indonesia that can affect the inflation. Indonesian people and goverment have done many efforts to increase the national rice production, for example by extensification. However, it can not be said success because the rate of   land transformation from rice field to other usages is much higher that the rate of extensification itself. Rice field transformation reaches 145.000 hectares each year. Due to that condition, growing rice in dry land (padi gogo) is a good alternative  to improve national rice production. Longterm objective of this research  is to create superior variety of dry land rice. The variety not only should be well adapted to Bengkulu Province climate and weather condition but also liked by local consumers. This research  used split plot design as the use of ameliorant  (farmyard manure and bokashi compost) as the main plot and 15 genotypes of dry land rice from cross breeding  as  the  sub-plot.  Result of research  showed that  there  are  5  genotipe  which tolelaran  to poisoned of aluminium that is ( UNHZ 5, UNHZ 23, UNHZ 24, UNHZ 29 and UNHZ 31. The most highest production rice genotypes based on its lifespan are UNHZ 31
