Abstract

This research aim to knows the effect of interaction of biofungicide active ingredient Trichoderma sp. with cow manure and best doses of biofungicide and best doses of cow manure on cocoa seedings growth (Theobroma cacao L.). This Research was conducted in Plant Laboratory, Disease Laboratory and experimental field faculty of agriculture, Riau University on Bina Widya Campus Km 12,5 sub-district of Simpang Baru, district of Tampan, Pekanbaru. This research was conducted from August to November 2015. This research used Completely Randomized Design (CRD) factorial that consisting of two factors. The first factor is the Trichoderma Biofungisida (B) consists of two levels            (0 and 25) g/polybag and second factor is the cow manure (P) consists of five levels (30%, 40%, 50%, 60% and 70%) /polybag. Both these factors resulted in 10 treatsment combinations, each combination made three replications, so that there are 30 experimental units. Each experimental unit consisted of two plants, so the total crop was 60 plants. Parameters measured were seedling height, number of leaves, stem convolution, ratio of crown roots  and dry weight. Data obtained from the research results were statistically analyzed by analysis of variance followed by a further test of Duncan's New Multiple Range Test (DNMRT) at 5%. Based on the research the result showed that the treatment Trichoderma biofungisida and cow manure significant on seedling height, number of leaves, stem convolution, dry weight and had no  significant on ratio of crown roots. Treatment of Trichoderma biofungisida burnt 25 g/polybag and cow manure 50% – 60%  /polybag can be recommended to get the growth of cocoa’s seedling. Keywords : cocoa breeding, Biofungicide, cow manure, Trichoderma sp.

Abstract

The research aims to obtain the superior genotypes of chili (Capsicum annuum L.) that give respons to fertilizer, able to grow and adapted so well, then produce  high  quality  of  yield  at  peat  land.  The  research  was  conducted  by experiment method. The experiment used Split Plot Design contained 3 times of repetition  and  2  times  formulation  of  fertilizer  that  consisted  formulation  of fertilizer I (Urea 600 kg/ha, TSP 500 kg/ha, KCl 400 kg/ha, organic fertilizer 10 ton/ha) and formulation of fertilizer II (NPK 700 kg/ha where organic fertilizer 15 ton/ha) as principal plot and 3 genotypes (IPB C-120 x IPB C-5, IPB C-2 x IPB C-120  and  IPB  C-5  x  IPB  C-120)  as  subplot.  The  variables  observed  were diameter of stem, high of  dichotomous, wide of branches, age of blooming, the diameter, length, and weight of fruit  respectively and the weight of fruits per plant. The result showed that superior genotypes and formulation of fertilizer in genotypes 3 (IPB C- 5 x IPB C-120) with the formulation of fertilizer II, it was NPK 700 kg/ha and organic fertilizer 15 ton/ha.   Keyword : Genotypes of chili, formulation of fertilizer, peatland.

Abstract

ABSTRACT                This study aims to determine the interaction of reed mulch and Urea, TSP, KCl fertilizers and to get the best dose on the growth and yield of mung bean. The research was conducted on August to October 2015 at the Experimental Farm, Faculty of Agriculture, University of Riau, Pekanbaru. This experiment based on factorial, arranged in Completely Randomized Design (CRD) with 2 factors and 3 replications. The first factor are 3 levels mulching reeds (without mulch reeds, mulch reeds 8 ton/ha and 12 ton/ha). The second factor are 3 levels of fertilizer Urea, TSP, KCl (25, 37.5, 25 kg/ha), (37.5, 56.25, 37.5 kg/ha) and (50, 75, 50 kg/ha). Data were analyzed statistically and Duncan's Multiple Range test at 5% level. The results showed that the interaction of mulch reeds and Urea, TSP, KCl had no effect on plant height, number of branches, flowering dates, number of pods per plant, number of pods pithy per plant, yield per plot and weight of 1000 seeds and influential the length of the main stem segments. Based on the research results 12 ton/ha of mulch reeds and 25, 37.5, 25 kg/ha of Urea, TSP, KCl was the best results on the growth and yield of mung beans.   Keywords: mung beans, mulch, fertilizers, yield.

Abstract

ABSTRACT The research purpose to observe the influence of a combination of bokashi fertilizer and urea fertilizer, and knowing dosage bokashi and urea for the growth and the production of plants mustard greens (Brassica Juncea L). The reaserch has implemented in the garden faculty the farm university of Riau in campus Bina Widya KM 12,5 Village Simpang Baru District Tampan Pekanbaru. The research has implented for 2 months was counted started April 2016 to Mey 2016. The study was carried out experiments using a Completely Randomized Design (CRD) factorial consting of 2 factors, the first factor is bokashi fertilizer (B) consist of 3 level and the second factor is urea fertilizer consist of 2 level, so in the can 6 a combination of treatment each 4 repetition, so obtained 24 plot. Each plot consist of 25 plants and taken 5 plants as sample. Parameters observed is high plants (cm), sum leaves (sheet) broad leaves (cm2), volume the root (ml) and the weight of fresh plants (g). Data obtained from the results of reasearch analyzed statistically with kind of a variety and proceed with further test (DNMRT) on the level 5%. Based on the results of reseach influence of giving bokashi fertilizer and urea fertilizer against the growth and the production of plants mustard greens (Brassica Juncea L) give the influence of a real in the parameters broad leaves and the weight of fresh plants. Based on the results of research obtained the results of the best on the giving bokashi fertilizer with a dosage of 2 tons/ha and dosage urea fertilizer 150 kg/ha so it can be advised to do fertilization to dosage on plants mustard greens.   Keyword: Mustard Greens, Bokashi Fertilizer and Urea Fertilizer
