Abstract

One of the efforts to increase the production of eggplant in an intensified manner is to balance fertilization. This study aims to determine the effect of giving sago pulp compost with different activators, as well as the best treatment in increasing the growth and production of eggplant. The research was carried out at UPT Faculty of Agriculture, University of Riau in May to August 2018 experimentally using a Completely Randomized Design (CRD) consisting of six treatments and three replications. Treatment includes S0 = Without compost, S1 = Sago waste, S2 = Compost sago waste with chicken manure activator, S3 = Compost sago waste with EM4 activator, S4 = Compost sago waste with Trichoderma activator, and S5 = Compost sago waste with Bacillus activator, each of 5 tons.ha-1 or 1,26 kg per 2,52 m2. The observed parameters included total N, total P, total K, pH, organic C, plant height, stem diameter, flowering day, harvest day, fruit weight, fruit diameter, fruit length, fruit weight per plant, number of fruits per plant, and production per plot on eggplant. The results showed that the nutrient content of N, P, K from the compost use each activator results had met the SNI compost quality standard (2004). Sago waste compost fertilizer with activator EM4 has a best chemical content of pH value 7.12, N-total 0.92%, P-total 1.26%, K-total 1.16% and C/N 33.54 and compost was able to increase fruit weight, fruit diameter, fruit length, fruit weight per plant, number of fruits per plant and production per eggplant plot. Compost of sago waste with chicken manure activator (5 ton.ha-1) was able to increase the growth of plant height and stem diameter of eggplant.Keywords: Compost, Sago waste, Activator, Eggplant, Quality of compost

Abstract

Soybean (Glycine max (L.) Merril) is a type of food that has high nutrition, so it is consumed by many people. The need for soybeans in Indonesia increases every year, while Indonesia's soybean production is not enough to cover soybean needs in Indonesia. This study aims to determine the effect of Organo Triba fertilizer supplemented with half the dose of NPK and get the best dosage for growth and components of soybean yields and compare with full dose NPK recommendations. This research was carried out in the experimental garden of the Faculty of Agriculture, University of Riau. This study used a randomized block design (RBD) of 1 factor and 4 replications with a control level as a comparison. The factors used were 5 doses of tribal organo fertilizer with 1/2 dose of NPK fertilizer and control levels with recommended dosage NPK without tribal organo. The results showed that 1.5 ton.ha-1 tribal fertilizer with 1/2 dose of NPK showed better results among other treatments in increasing the number of branches. Organo Triba fertilizer with 1/2 dose of NPK does not increase the yield component, because the nutrients that are sufficient in the growing media. Keywords:     Soybean, Organo Triba fertilizer, NPK fertilizer

Abstract

Rice plants (Oryza sativa L.) is important food crops in Indonesia to boost production of upland rice crop nutrients needed in sufficient quantities especially N, P dan K. This research aims is to determine where the rice varieties that give effect to N, P and K fertilizer. This research was conducted in screen house of Agriculture Faculty at Riau University, Pekanbaru. This research take 7 months start from August 2013 till February 2014. This research was performed experimentally using a Completely Randomized Design (CRD) consist of 2 factor,  tested by LSD 5% level. The first factor is the upland rice varieties cosisting of varieties Santan, varieties Pulau Petai and vvarieties Inpago 5 and second factor N, P dan K fertilizer. The results showed the granting of a wide measure of fertilizer N, P dan K are not real movers shakers of all parameters, except for the amount of grain panicle effect is real and varieties pulau petai give relatively higher results when viewed from the result. Grating a rate of fertilizer (Urea 0,38 g, SP-36 0,34 g, KCl 0,15 g/clumps) on inpago varieties can increase the height of the plant, tillers maxsimum number, number of productive tillers and the amount of grain panicle. While granting a measure (Urea 0,75 g, SP-36 0,68 g, KCl 0,3 g/clumps) increased panicle emergence time, percentage pithy grain per panicle, grain weight clumps dan weight of 1000 filled grain. Keywords: fertilizer N, P and K, the local varieties of upland rice, yielding varieties.

Abstract

This research aimed to determine the effect of bokashi fertilizer and NPK on growth and production of sweet corn. This research was conducted at the experimental farm of the Faculty of Agriculture, University of Riau, Pekanbaru from April 2014 to July 2014. The study was carried out experiments using a Randomized Block Design (RBD) factorial consisting of two factors: Bokashi and NPK fertilizer with 3 replications. Parameters measured were plant height, time of harvest, number of cobs per plot, the diameter of the cob without husk, cob length without husk, cob weight without husk, cob weight with husk, and production per plot. The results showed that the combination of Bokashi and NPK fertilizer application significanly affected the harvest age and numbers of cobs, bokashi fertilizer treatments significanly affected the diameter of the cob whitout husk and cob weight without husk whereas NPK fertilizer treatment significanly affected plant height, time of harvest, number of cob per plot and prodution per plot. Bokashi fertilizer application 15 ton/ha and 150 kg/ha NPK/ha can accelerategrowth and production of sweet corn.   Keywords: Sweet corn, bokashi fertilizer, NPK fertilizer

The purpose of this research is to find out the effects of herbicides types used in weed control against sweet corn growth and production on a triangular planting system. The experiment has been conducted at the Experimental Farm of the Faculty of Agriculture, Riau University, Soil Laboratory agricultural faculty, and Botani Laboratory FMIPA Riau University from December 2016 to March 2017. The experimental unit was arranged in a Completely Randomized Design, consisting of 4 treatments and 5 replications. The treatments consisted of the without herbicides, herbicides isopropil amina glifosat, paraquat diclorida and mesotrion + atrazine. The Observed parameter are planth height, girth diameter, chlorofil content, male and female flower appearance time, cob weight without cornhusk per plant, cob yield cornhusk per plot, number of seed rows, cob diameter, cob length, weed plant biomass and vegetation analysis before and after treatment. The data acquaired from analysis of variance were tested with Duncan’s multiple range test at 5% level. Research result shows that Mesotrion + Atrazine treatments is better in raising sweet corn yield component. Key words : Herbicide, triangular planting system, sweet corn

Abstract

Rice is plant resulting rice which become main food to people but production of rice still low and need an effort to increase the production of rice. The research aims to obtain the best dosage of rice husk ash with manure on the growth and yield of field rice in peatland at hall of oil palm area. The research was conducted at the experimental farm of the Agricultural Faculty University of Riau, Rimbo Panjang Kampar from August-December 2014. The research was conducted completely a Randomized Block Design (RBD) factorial consisting of 2 factors with 3 replications. The first factor are: Aplication of rice husk ash with 4 level (tons/ha) namely : A0 (0), A1 (2.5), A2 (5), A3 (7.5) and the second factor are : Manure application with 3 levels (tons / ha), namely: K0 (0), K1 (5), K2 (10). The data obtained by analysis of variance (ANOVA) was tested further by Duncan’s New Multiple Range Test (DNMRT) at the level of 5%. The results showed that the application of rice husk ash 7.5 tons / ha and manure 5 tons/ha gave the highest yield of dry grain is 1056.67 g (equal to 3:52 tons / ha).
