In developing new superior rice varieties, farmers’ preferences are important things to study and high yield potential. The study aimed to obtain new superior varieties of adaptive rice based on plant growth and productivity performance and determine respondents’ preferences for the varieties studied. The study was conducted in rainfed rice fields, Majalengka Regency, West Java Province, from April to August 2020. The study used a randomized block with 6 treatments: Inpari 32 varieties, Inpari 39, Inpari 42, Inpari 43, Pajajaran, and Siliwangi, and repeated 5 times. The observed parameters consisted of: growth, yield components, and yields were analyzed by ANOVA followed by Duncan’s Multiple Range Test at a 5% level. The respondent’s preference test for grain and rice and organoleptic characters used a Likert scale and analyzed non-parametrically (Friedman test). The results showed that the Inpari 43 variety gave the highest yield. Still, farmers preferred the Inpari 32 variety to be developed because it has characters favored by farmers (respondents), namely short plant height, a large number of tillers, thin grain shape, white rice color, and fluffier rice taste.

“…This means that the character of the number of tillers of rice plants produced in high numbers will be able to support the yield of rice plants with high numbers as well. According to Agustina et al (2005), the maximum number of tillers and the number of productive tillers per clump were positively correlated with the weight of milled dry grain per clump of rice plants.…”

Improper processing of rice field systems and lack of organic matter in the soil to meet the nutrient needs of rice plants resulted in low rice production. Increased production of rice plants can be overcome by giving compost of palm oil empty fruit bunches (TKKS) with the system of rice intensifications (SRI) method, because the organic matter contained in the compost can improve the physical properties of the soil. This study aims to obtain the best dose of empty fruit bunch (EFB) compost and to see its effect on the production of lowland rice (Oryza sativa L.) by using the modified SRI method. The research was conducted from January-April 2019 at the UPT Experimental Garden, Faperta, Riau University. This study applied a completely randomized design (CRD) consisting of 5 treatment levels. They are 0 gr.polybag-1, 50 gr.polybag-1, 75gr.polybag-1, 100 gr.polybag-1 and 125 gr.polybag-1. The results showed that giving empty fruit bunch (EFB) compost with the SRI method gave an effect on productive tillers, pithy grain per panicle and grain weight, but did not affect panicle exit age, harvest age, percentage of pithy grain per panicle and 1000 grain weight of pithy grain. The best treatment dose was found at a dose of 20 ton.ha-1 because it could increase several components of lowland rice production of the Batang Piaman variety.

High genetic diversity in chili is the basis for a chili breeding program. One of the methods to increase diversity is through crossing. There are several crossing designs in order to produce new varieties, such as diallel crossing. Diallel analysis is a method for studying the inheritance of characteristics from various crossings. The aim of this research was to estimate the genetic parameters, the general combining ability (GCA) and specific combining ability (SCA) of six inbred lines of chili. The research was conducted in November 2008-May 2009 at the Experimental Farm Leuwikopo IPB. Genetic materials used were six inbred lines of chili (IPB C2, IPB C9, IPB C10, IPB C14, IPB C15 and IPB C20) and the F1s of the combination of six inbred lines. The experimental design was Randomized Complete Block Design with a single factor, namely genotype. The number of genotypes were 36 with three replications, so there were 108 units of experiment. The crossing design used was diallel crossing design. The results showed that there were no interaction between genes on the dichotomous height and fruit weight, significant additive effects, the control genes spread unevenly, and relatively high heritability values. Genotype which carried recessive genes the most was IPB C14 and genotype which carried the most dominant genes was IPB C10. IPB C10 showed the highest GCA for dichotomous height and IPB C2 showed the highest GCA on fruit weight. The crossing between IPB C2 x IPB C10 showed the highest SCA for dichotomous height. For fruit weight, crossing of IPB C2x IPB C14 had the highest SCA. Crossing combination of IPB C2 x IPB C14 was the best hybrid.
