Abstract

This study aims to determine the interaction of organic manure and N, P and K fertilizeron the growth and production of onion as well as getting the best dosage. This research has been carried out in the garden Experimental Faculty of Agriculture, University of Riau from March to May 2016. The study consists of two factors, the first factor that manure with a dosage of 10 ton/ha, 20 ton/ha and 30 ton/ha. The second factor is urea, TSP and KCl which consists of three levels without treatment Urea, TSP and KCl, 1/4 the recommended dosage, Urea        125 kg/ha + TSP 50 kg/ha + KCl 50 kg/ha and 1/2 recommended dosage, Urea 250 kg/ha + TSP 100 kg/ha + KCl 100 kg/ha, which is arranged in a randomized block design (RAK). From these two factors obtained 9 treatment combinations, each treatment was repeated 4 times, thus obtained 36 experimental units. Observation Data were statistically analyzed using ANOVA, the results of variance followed by using Duncan's multiple range test at 5% level. The parameters measured were the number of leaves, number of tubers per hill, convolution bulb, tuber fresh weight per plant, tuber fresh weight per plot and weights shelf per plot. Data results shows that the best results using cow manure dosage of 30 ton/ha and urea 250 kg/ha, TSP 100 kg/ha, KCl 100 kg/ha.Keywords: Onion, Cow Manure, Fertilizer TSP and KCl

Abstract

This study aimed to compare macrofauna of burnt and unburned peat soil and to know the effect of time increase after fire to macrofauna peat soil. This research was conducted by survey method, sampling for soil macrofauna data determined by purposive random sampling method that is by choosing the location in accordance with the purpose of research. The soil samples were taken on unburnt peatland, in peat a week after fires and in peat 4 months after fires with a capture area of 1 m x 1 m at a depth of up to 15 cm taken 6 samples so that there were 18 samples. The data obtained from the results of research and calculations are listed in table form. Then the data is analyzed statistically descriptive. The results of this study indicate the type and number of macrofauna individual soil on peat is not burned more than peat a week after the fire and, peat 4 months after the fire. Time-increasing effects on peat a week after a fire have increased the type and number of macrofauna because macrofauna proliferate in peat 4 months after the fire.Keywords:Macrofauna, Fire and Peat.

Abstract

The purpose of this research was to know the effect of sodium chloride (NaCl) on the quality of fresh palm fruit bunches  and Crude Palm Oil (CPO) also to find the best concentration of sodium chloride.  The method used in this research was a Randomized Block Design (RBD) experiment with six treatments and four replications.  The treatments were NaCl concentrations P0 (0%), P1 (5%), P2 (10%), P3 (15%), P4 (20%), and P5 (25%).  The collected data were statistically analyzed by using Analysis of Variance (ANOVA) continued by Duncan’s New Multiple Range Test (DNMRT) at 5% level.  The parameters observed were loss of brondolan mass, yield, moisture, specific gravity, levels of free fatty acid (FFA), and impurity content. The results of this reseach showed that NaCl can influence the quality of fresh palm fruit bunches that yield the loss of brondolan mass, as well as to the quality of CPO, the levels of  FFA, moisture, and specific gravity.  The treatment chosen from the result of this research was P5 (concentration NaCl of 25%).  Treatment of P5 has levels FFA of 2.05%, moisture 0.216%, impurity content of 0.062%, specific gravity of 0.919, yield of 23.43% and loss of brondolan mass of 2.81%. Keywords: Natrium chloride, fresh fruit bunches, and crude palm oil.

Abstract

Red dragon fruit (Hylocereus polyrhizus) is a plant cultivated in Riau Province especially Siak district such as Tualang and Bunga Raya. However, productivity of dragon fruit is still low because attacks of diseases infection. The aim of the research is determine the diseases, the cause of the diseases and their intensity caused by fungi on the red dragon fruit plants. Based on the observation, the diseases that infected the dragon fruit plants are anthracnose disease caused by Colletotrichum sp., stem rot diseases by Sclerotium sp., and fusarium wilt by Fusarium sp., and orange spot diseases on fruit by Alternaria sp. The intensity of the disease attacks the dragon fruit in Bunga Raya higher  than in Tualang, i.e : 50% of anthracnose disease, 60% stem of rot disease, 30% of layu fusarium, 17,5% of orange spots on the fruit. While the intensity of the diseases in Tualang are 57.5% of anthracnose, 50% of stem rot diseases, 30% of fusarium wilt, and 15% orange spots on the fruit. Keywords : red dragon fruit plants, fungal disease, disease intensity
