Abstract

[RESPONSE OF GROWTH AND YIELD OF FIVE RICE HYBRID GENOTYPE ON THE ORGANIC FERTILIZER OF PALM OIL BUNCHES ON ULTISOL]. Oil Palm Bunches (OPB) are solid waste potential as organic fertilizer to improve soil physical, biological and chemical properties, especially on ultisol soils for rice development. This research was conducted in August - November 2019 in Padang Harapan, Bengkulu City. The materials used were F1 rice seeds, OPB organic fertilizer. The experimental design was a factorial Randomized Completely  Block Design (RCBD) with 2 factors. The first factor was 5 hybrid genotypes (F1), namely, Kuning x Inpago5, Kuning x Inpago9, Kuning x Inpago6, Arang x Inpago8, and Kuning x Salumpikit. The second factor was the dosage of OPB, namely 0 (control), 10 tonnes/ha, 15 tonnes/ha, and 20 tonnes/ha, the experiment was repeated 3 times. The variables observed were plant height, number of productive tillers, flowering age, harvest age, the total number of fill grains, number of filled grains, number of empty grains, 1000 grain weight, and grain weight/hill. The results showed that there was an interaction between genotype and OPB on the number of tillers. The interaction between the Kuning x Salumpikit genotypes and 10 tonnes/ha of organic fertilizer produced the largest number of tillers. Genotype G3(Kuning x Inpago6) produced the best rice growth and yield. In this study, the optimum point for OPB fertilization on growth and yield of the five genotypes tested had not been obtained.

Abstract

[FRUIT PERFORMANCE OF 26 GENOTYPES OF MELON (Cucumis melo L.) IN WICK HYDROPONIC CULTIVATION SYSTEMS]. Fruit performance is determining quality factor for melon fruit. This research aimed to obtain the melon genotype which has the best fruit quality by the cultivation of the wick hydroponic system. The research was conducted from June to September 2020 in the greenhouse of the Agronomy Laboratory, Bengkulu University. The study was compiled with a single-factor of the melon genotypes using randomized complete block design (RCBD) with two replications. The genotypes were G23, G27, G28, G29, G38, G39, G40, G41, G42, G43, G45, G46, G47, G48, G49, G52, G53, G55, G57, G58, G60, G62, G63, G64, G65, and G66. The best genotypes for fruit length characters were G28 and G42. The best genotypes for fruit diameter character were G52, G58, G60, G64, and G66. The best genotype for fruit thickness character was G43. The best genotype for total dissolved solids character was G45. The best genotypes for fruit weight characters were G58, G66, and G60.
