Chromolaena odorata Compost Affected Soil Chemical and Rice Crop (Oryza sativa L.)

The study entitled "Chromolaena odorata Compost Affected Soil Chemical and Rice Crop (Oryza sativa L.) hadbeen conducted in Padang City, West Sumatra. It was started in February 2015 to May 2015. The study aimed wasto examine the mechanism of amendment soil chemical properties and nutrient uptake of rice crop was fertilized ByChromolaena odorata Compost. The experiment was conducted by using Randomized Complete Design (RCD) inSplit Plot Design with the main plots were three varieties of rice crops namely; Cisokan (V1); Pandan Wangi (V2)and Red Cempo (V3). The subplot consisted three types of fertilizer composition; 5 Mg ha-1 Compost C. odorata(CCP) +100% Artificial Fertilizer Recommendation (AFR) (F1); 7.5 Mg ha-1 CCP+75% AFR (F2); 10 Mg ha-1 CCP+50% AFR (F3), with three replications. Data was analysed by using the F test significance level of 5%, and anHonestly Significant Difference test (HSD) α 5%. Parameters include analysis of soil chemical properties, manure,analysis of nutrient uptake and the weight of dry crop biomass. The study indicated there was amendment in soilchemical properties after the application of C. odorata, compost achieving optimal fertility for rice crop. Nitrogen andother minerals uptake in rice crop increased due to the increased provision of artificial fertilizers escorted by loweringthe dose of C.odorata compost. The ability about the nutrient uptake of rice crop is higher in rice Pandan Wangi andcauses the higher forage yield than rice Cisokan or Red Cempo.

The aim is to determine the optimum combination of inorganic fertilizer and organic materials for increasing the productivity of rice crop (Oryza sativa L.). The experiment was conducted in February- June 2015 in Kebadu, Sanggau, West Kalimantan, Indonesia. The study area was located at 00°0.08,785’N north latitude and 110°0.07,175’E east longitude with ultisol soil; the altitude is 32 m above sea level, rainfall level ranges between 185-267 mm month-1, and the solar radiation is 375.49- 452.58 cal cm-2 day-1. This study used a factorial randomized block design. The first factor was the inorganic fertilization (without fertilizer, inorganic fertilizer 50%, 100%, and 150%) and the second factor was the addition of organic materials (EM4 2 l ha-1, chicken manure 2 t ha-1, and manure 2 t ha-1 + EM4 2 l ha-1). Results showed that the application of chicken manure and a combination of chicken manure+EM4 could reduce the need for inorganic fertilizer NPK by up to 50% with productivity that ranged from 4.18-4.20 t ha-1; this is relatively similar to 100% and 150% inorganic fertilizer NPK, and can increase the harvest by up to 68% compared to the no-NPK inorganic fertilizer.

Blight Disease

Bacterial Leaf Blight disease epidemically damaged the rice crop. Absence of resistance against BLB disease in MTU1010 is one of the main reason for these epidemics. Thus, there is urgent need to search for resistant source and subsequently, their phenotypic evaluation to validate the resistant source. In this paper discussing about the highlights of phenotypic evaluation of Bacterial Leaf Blight resistance in MTU1010 NIL variety of rice. In the present study, fifty advanced breeding lines along with parents i.e., MTU1010 NIL X Akshayadhan NIL, were screened for bacterial leaf blight disease, Thirty-four breeding lines were shown resistance against bacterial leaf blight disease.

The research was conducted from August 2014 to Januari 2015 in the Ultisol Land, Pematang Berangan Village, Rokan Hulu Regency, Riau Province. The study aims to determine the availability of P, P and Si uptake by upland rice plants granting silicate and phosphate fertilizer on Ultisol land. The form of this research is experimental factorial completely randomized design consist of two factors. The first factor is silicate consists of four levels (0, 50, 75, and 100 kg SiO2/ha), while the second factor is phosphate fertilizer consists of four levels (0, 36, 54, and 72 kg P2O5/ha), each combination was repeated three times. The results showed that administration of silicates and phosphates increase the availability of P, P and Si uptake of upland rice crop. Giving of 100 kg SiO2 and 36 kg P2O5 per hectare increase uptake of P and Si, each respectively increased by 208 % and 218 % compared without silicates and phosphates fertilizer.

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.
