Abstract

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.

Abstract

The selection rice of resistant to pests S. oryzae can be done through the utilization of local paddy germplasm. The study aims to determine the level of resistance of local upland rice Aceh to against pest infestation S. oryzae. The results showed that the local paddy rice from upland Aceh has a level resistance from resistance until moderately to susceptible to pest infestations S. oryzae. The rice from varieties Depet classified in the category-resistant, while varieties Putih, Toa, and Bontok classified in the moderate category. Local rice upland Aceh from varieties Pulo Aceh and Tajuk classified in the category of moderate to susceptible to pest attack S. oryzae during storage rice. Results of correlation analysis showed that resistance rice local upland Aceh affected by moisture content (r = 0.864*; P<0.05). Results of correlation analysis showed that positive correlation non significant between resistance with characteristic dimensions of rice such as length (r = 0.106; P> 0.01), negative correlation non significant with wide (r = -0.339; P>0.01), and a positive correlation non significant with ratio (r = 0.167; P>0.01). The content of protein and moisture content of the rice had a positive correlation with the population of adult S. oryzae (moisture content: r = 0.928**; protein: r = 0.884** P<0.01), the percentage of perforated rice (moisture content: r = 0.872* P<0.05; protein: r = 0.945** P<0.01), and the percentage of rice powder (moisture content: r = 0.912**; protein: r = 0.951** P<0.01) during storage

Abstract

Land changes become oil palm plantations accused of contributing greenhouse gas emissions (GHG) included in the mineral soil, therefore it is very important to gather information in mineral soil CO2 emissions to support mitigation and adaption to climate change. This purpose of this research determine the CO2 emissions in the oil palm plantations planted crops in the vegetative stage and generative phase, as well as to determine the ratio of CO2 emissions in the oil palm plantations planted crops in the vegetative stage and generative phase. This research was conducted in November 2015 to February 2016 in Subdistrict of Tambang, District of Kampar, Province Riau. The method used in this research was Random Block Design with four treatments and replications. The treatments were oil palm-bera, oil palm-corn, oil palm-soy bean, oil palm-intercropping corn soy bean. The research showed that CO2 emissions in the oil palm plantation intercropped with crops (corn and soybeans) in the vegetative phase showed no significantly different. Comparison large of CO2 emissions indicated oil palm-corn vegetative phase.

Abstract

Research on the effect of giving various concentration ethepon to growth and production of cucumber was conducted in Nagari Kacang Kecamatan X Koto Singkarak, Solok, West Sumatra, from June to August 2008. The objectives of the study were (1) get interaction between several concentrations of ethephon with cucumber varieties, (2) obtaining the best ethepon concentration, (3) and knowing cucumber varieties that have better production. Factorial-factored experiments in Randomized Block Design with 2 factors and 3 groups. The first factor of ethepon concentration consisted of five levels 0, 100, 200, 300, 400 ppm. The second factor is cucumber varieties of Local and  Antara varieties. Observed variables: plant length, number of branches, when first male flowers appear, when the first female flowers appear, the number of male flowers, the number of female flowers, the number of straight fruit, the number of fruit is not straight, the fruit weight is straight, fruit weight is not straight. Providing ethepon concentration with crop varieties has an effect on growth and production of cucumber , that is when the first male flowers appear (hst). Provision of ethepon concentration of 200 ppm showed a better effect on the number of female flowers, the number of straight fruit, and the weight of the fruit straight. Factor varieties, singularly different to plant length variables, when the first female flowers appear, the number of straight fruit, the number of crooked fruit, the weight of the fruit straight, and the weight of the bent fruit. Local varieties show better production than Antara varieties.

Abstract

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.

Abstract

The purpose of this research is determining the effect of some  treatment combinations and to determine the combination of best compost bunches empty palm oil and dolomite that could support growth seeds palm oil plantations in a main nursery. This research has been conducted in the experimental field, Agriculture Faculty, University of Riau from April to July 2015. The research used Completely Randomized Design Factorial that consisting of two factors. The first factor is giving compost bunches empty palm oil : (37,5, 75 and 112,5 g/polybag).  The  second  factor  is  giving  lime  dolomite  (CaMg  (CO3)2) : (9, 18 and 30 g/polybag).   Each combination made three replications and two plants. The data were statistically analyzed using analysis of variance and the means were tested with Duncan 5%. The research results show that combination of compost bunches empty palm oil and dolomite had show the real effect on the increase in diameter hump of seedlings , but the effect not real on the parameters height of seedlings,increase number of leaves, volume roots, ratio crown rootsand and dry weight of seedlings. Combination compost bunches empty palm oil 112,5 g/polybag and dolomite 18 g/polybag showed better results for the growth of palm oil seedlings.
