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.

Beneficial Elements

Background: The beneficial elements availability such as silicon was determined rice growth and yield. Rice requires a different dose of silicon during the growing period. Experiment was aimed to investigate the effect of silicate levels, rice varieties and the interaction of the two on the growth and yields of two local Indonesian varieties of rice. Methods: A completely randomized design of factorial pattern with 4 replications was used in the experiment. Treatments consisted of No added SiO2 (Si-0); added 100 and 200 kg SiO2 ha-1, respectively for Si-100 and Si-200 and two local rice varieties, Pandan wangi (P1) and Mentik susu (P2). Result: The treatment had no significant effect on growth and yield of rice. Addition of 100 and 200 kg SiO2 ha-1 to P1 and P2 did not show a significant difference on the growth and yield of rice compared to control (P0). Plant height and root dry weight at P1 was lower than P2, but the 1,000-grain weight was showed, vice versa. Silicon addition up to 200 kg SiO2 ha-1 may not be recommended to be applied in rice cultivation, especially Pandan wangi and Mentik susu varieties. Improving the two varieties, further research is needed by increasing the silicon doses.

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.

Mutagenic Effects

The available natural diversity highly limits the effort to improve the production of upland-rice with delicious and aromatic flavors. However, the mutagenesis can help improving the natural diversity. The aromatic-upland rice seeds, cv. Inpago Unsoed 1, were soaked in solution of NaN3 with the doses of 0 mM, 1 mM, 2 mM, 3 mM, 4 mM, 5 mM, 6 mM, 7 mM, 8 mM, 9 mM, and 10 mM, in four replications in completely randomized design. The observation included LD50, germination percentage at first-count and final-count. Data were tabulated and analyzed with CurveExpert 1.4 software for LD50, and generalized linear model in the PROC-GLM procedure of SAS 9.1 software. The means were generated and compared through Dunnett option, at probability level of 5%, in order to determine the difference in means between mutated and non-mutated seeds. The results show that the attributes of rice physiology affected by mutagenesis are sensitivity of rice to NaN3 with LD50 at 8.84 mM, and significant effect of NaN3 on the decreasing capacity of seed germination at > 6 mM for first count, and > 7 mM for final count.Keywords: germination, inpago unsoed 1, median lethal dose, rice, sodium azide
