The aim of this research was to know the influence of concentration and interval of Liquid organic manure (LOM) Unitas Super  (US) form Chromolaena odorata on growth and yield of black rice (Oryza sativa L.). The experiment was conducted from October 2016 to March 2017 in Lubuk Minturun Urban Village, Koto Tangah Sub-district, Padang. The experiments were arranged in Completely Randomized Design, with 6 doses of POC Unitas Super (US) (v/v) with water, ie; 0 ml L-1 (F1); 50 ml L-1, 1 time a week (F2), 50 ml L-1, 1 time 2 weeks (F3), 100 ml L-1, a weekly (F4), 100 ml L-1, 1 time every 2 weeks (F5); 150 ml L-1 POC US, 1 time every 3 weeks (F6), and 3 replications. The data obtained were analyzed using analysis of variance (ANOVA) 5% real level. If the treatment had a significant effect, it was continued with LSD test of 5% real level. Parameters observed include; Plant height, the maximum number of tillers and productive, flowering age, harvest, panicle length, the number of grains per panicle, weight of 1000 seeds, the weight of dry grain per hectare, percentage of empty grain and harvest index. The experimental results proved that there was an influence of LOM Unitas Super treatments on maximum tillers, empty grain, panicle length and dry grain harvest, and some other parameters were not significance. The conclusion was the giving of 50 ml L-1 POC Unitas Super given every week is the best treatment. The highest rice yield reached 6.79 tons ha-1 dry milled grain, with harvest index reached 0.49.

Materials Used

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.

Two Stages

This study was intended to examine the pattern of interaction and mutant distribution of endophyticbacteria as a result of the transformation of the gfp gene in rice plant tissue in vitro. This study used 5isolates of rice endophytic gfp mutants namely IM-1, IM-3, IM-8, IM-24, IM-25. The study wasconducted in two stages, stage I using a simple Complete Complete Design (RAL) and stage II usingfactorial Complete Randomized Design (RAL) with a factor of 1: the type of plant tissue and factor 2:the type of mutant isolates.The results of the study of patterns of bacterial interactions in rice tissueculture showed that the percentage of infections of 5 gfp mutant endophytic bacteria isolates rangedfrom 4% -17%. The highest percentage was in mutant isolates IM-3 + gfp (17%) and the lowest was inmutants IM-8 + gfp (4%). The interaction pattern was not significantly different from the parametersof seed germination time. On the other hand, in observing the distribution of bacteria that infect ricetissue, they showed different pattern. Mutant IM-1 + gfp infection is higher in stem tissue, whereasIM-24 + gfp mutant infection is higher in root tissue and IM-25 + gfp mutant infection is higher inleaf tissue. Mutant infection of IM-25 + gfp in leaves had the highest number of colonies reaching1.64 x 109 cfu/ml.

The objective of this research was to investigate the effectiveness of combination of bio-slurry fertilizer and NPK fertilizer on the growth and production of two varieties of rice. The experiment was assigned in a completely randomized design of factorial pattern. The first factor was the combination of bio-slurry and NPK fertilizer that consisted of P0 = no added fertilizer (control) 0 ton/ha, P1 = NPK fertilizer 550 kg/ha (165 kg N, 33 kg P, 45 kg K); P2 = bio-slurryfertilizer 2.3 tons/ha (45 kg N, 14 kg P, 23 kg K) and NPK fertilizer 400 kg/ha (120 kg N, 24 kg P, 32 kg K); P3 = bio-slurryfertilizer 4.6 tons/ha (90 kg N, 28 kg P, 46 kg K) and NPK fertilizer 250 kg/ha (75 kg N, 15 kg P, 20 kg K); P4 = bio-slurry fertilizer 5.9 tons/ha (115 kg N, 36 kg P, 59 kg K) and NPK fertilizer 100 kg/ha (30 kg N, 6 kg P, 8 kg K); and P5 = bio-slurryfertilizer 8.5 tons/ha (165 kg N, 52 kg P, 85 kg K). The second factor was varieties of rice that consisted of V1 : IR-64 and V2 : Ciherang. Each treatment was repeated three times. Parameters observed were plant height, number of tillers, weight of 1.000 grains, and rice production. Data were analyzed using ANOVA and continued with Duncan’s Multiple Range Test (DMRT). The results showed that the combination of bio-slurry fertilizer and NPK fertilizer were significantlyaffect (p <0.05)all observation parameters, while varieties of wetland rice did not show significant effect on all observation parameters (p<0.05). The application of bio-slurry fertilizer in single treatment or in either combination with NPK fertilizer had the same result with the treatment of NPK fertilizer on the growth and yield of rice.

Rice (Oryza sativa L.) is first staple crop of Nepal. The national average yield of rice is less than its potential yield, for which poor agronomic management has been reported as the critical factor. Among various agro-management practices seedling age, seeding density and nitrogen rates significantly affect the growth and yield of rice. The lower seeding density produces the taller plant, more effective tiller, lower sterility and higher grain yield. On the other hand, seedling of older age from higher seeding density gives the lowest yield. Transplanting younger seedling with low seeding density and application of recommended dose of nitrogen gives a higher yield. This article summarizes various effects of seedling age, seeding density and nitrogen rates on plant height, number of effective tillers, number of filled grains, thousand grain weight and grain yield of rice. This information may be useful for maize growers and researchers.
