Abstract

Coffee seed has endocurp that is inipcrnicabic who water and Oj, because it contains com-plex of polysaccharide, hemicellulosc, fat and protein. This condition could prevent germi-nation. To overcome this problem, there are several alternatives available, one of them bypeeling endocarp and submerging in gibberellin hormone solvent. This experiment wasconducted in Breeding Laboratory, College of Agriculture, University of Riau. The designM a s Complete Randomized Varianged in factorial 2 factors. First factor is three levels ofgibberellin (0 ppm, 10 ppm and 20 ppni) and the second factor is 3 endocarp treatments(without peeling, 50 % of peeUng and 100 % of peeling). The results showed that 100 %peeling and submerging in gibberellin of 20 ppm could accelerate and increase germinationpercentage, howives cotyledon breaker, there is no significant difference among the inter-action of giberalin and peeling endocarp.

Abstract

The objective of this research was to observe the effect of interaction between plant catalyst 2006 fertilizer and gibberellins on the growth and yield of tomato. This research used Completely Randomized Design (CRD) which was arranged in factorial with two factors and three replications. The first factor was concentration of plant catalyst 2006 fertilizer (P) which consisted of P0 (0 g/l), P1 (1,0 g/l), P2 (I,5 g/l), P3 (2,0 g/l), and P4 (2,5 g/l). The second factor was Gibberellin (G) which consisted of G0 (0 ppm), G1 (50 ppm), G2 (75 ppm), G3 (100 ppm), and G4 (125 ppm). Parameters observed were plant height, total flower, harvesting time and fruit weight. The result of this research shows that interaction between plant catalyst 2006 fertilizer (2,0 g/l) and gibberellins (50 ppm) exhibited the best effect on harvesting-time of tomato production.

Abstract

The objective of this research was to achieve the best CMA dosage for soybean growth and production in red yellow podzolic soil. This research was carried out experimentally by Completely Randomized Design (CRD) which consisted of 5 treatments (0 g CMA/plant, 10g CMA/plant, 20g CMA/plant, 30g CMA/plant, dan 40g CMA/plant) and 4 replications. Parameters observed were CMA infection percentage (%), the age of flower bloom (day), the age of harvesting time (day), amount of pods (pods), and seed dry weight (g).  The analysis of Variance was followed by Duncan’s New Multiple Range Test at 5% level. The result of this research concluded that application of 40g CMA/plantin red yellow podzolic soil will increase soybean growth and production.

This research was carried out in Organic Agriculture Plot, Faculty of Agriculture, Riau University . The experiment used Completely Randomized Design with two factors. The first factor was liquid complement fertilizer which consists of 3 levels (without liquid complement fertilizer, Bayfolan and Gardena). The second factor was chicken manure, which consists of 4 levels (without chicken manure, 5 ton/ha, 10 ton/ha, and 15 ton/ha). The analysis of variance will be continued with Duncan New Multiple Range Test. The result of this research showed that the application of combined Bayfolan in 3 cc/l water with 15 ton/ha chicken manure influence all parameters measured which are height of plant, the number of leaf, leaf width, production of the plant, weight of the plant, chlorophyll analysis and plant growth rate.

Abstract

An experiment has been designed to investigate the impact of Phosphorous (P) fertilizer on seed quaaliti during seed development of several Soybean (Glycine max L. Merrill) cultivars. The field experiment was carried at University of Riau Agriculture Experiment Station using a complete randomized block design with three replicates. Soybean cultivars such as Willis, Malabar, Kipas Putih and line KM-19-BE were planted in three rates of P fertilizer; ie P0 = 0 kg P2O5 as a control, P1 = 25 kg P2O5, and P2 = 50 kg P2O5 per hektare. Seed quality including seed viability and seed vigor was observed at 10 days interval from 20 to 50 days after anthesis (DAA). It was found that seed quality was very low at early stage of seed development and tent to reach its maximum value as seed matured. Addition of P fertilizer to the plant increased some components of seed quality at early stage of seed development until 40 DAA. The values of seed viability and seed vigor were higher in seed harvested from plant fertilized by P than control, mainly for seed obtained at early seed development. This results indicated that P fertilizer application would improve seed quality especially of seed harvested at early seed development of some soybean cultivars.

Abstract

cultivated tomato varieties those well adapted to the growing environment. Varieties have different levels of sensitivity to environmental conditions. The result will be reach the maximum level when cultured in a suitable environment. The objective of this research was to find the genotypes of tomato that has good growth and yield in the low land. This research use Completely Block Randomized Design (CBRD) that consists of 6 treatments and 3 replications. These treatments consist of 6 genotypes, those IPB T34-7-7, IPB T3-8-10, IPB 2201-5-8b, IPB T64-2-2(1), Karina and  Ratna. The result of this experiments suggest those the genotype significantly affect (days to flowering, harvesting time, plant height, stem diameter, weight per fruit, fruit length, fruit diameter, fruit flesh thickness, number of fruit cavities, and total weight per plant), affect number of fruit cavities however genotype did not significantly. The experimental result showed those genotypes IPB T3-8-10 has the highest total fruit weight (701.1 g) compared to Ratna and Karina. Genotypes IPB 2201-5-8b has the lowest total fruit weight (174.0 g).   Key words : Growth, Lycopersicum esculentum, genotypes, low level land

Abstract

Study lasted from June until November 2011, at Bogor Agricultural University (IPB), Leuwikopo, Dramaga. This research using Randomized Complete Block Design (RCBD), one factor consisting of 20 genotypes of chilli that comes from the collection of IPB (C2, C5, C105, C111, C117, C118, C120, C160, C51, F5110005-91-13-5, F5110005-91-13-12, C157, C159, F5120005-5-11-1, F8002005-2-9-12-1, C140, C19, C18, C143, C145) with three replications. Data were analyzed using the F test and test of Duncan New’s Multiple Range Test (DNMRT) 5% level. Result shows that the genetic variability and heritabilty of 20 genotypes chilli in quantitative parameters were different each other.Genotypic coeffecients of variation (GCV) at intervals between 1,36 -22,11%. The heritability value at intervals 42.05%-91.80%. Almost all of the observed variables had high heritability value, except leaf length and flowering date which is only on intermediate criteria. For weight per fruit, C143 reveal significant value than other genotype and yield per plant C5 reveal significant value than the others. It indicate that C143 and C5 can be selected as Hybrid chilli plant. The genotypes tested in this study had a high level of variability that could potentially be used as a parent for crosses. Meanwhile, the 20 genotypes that observed qualitiatively shows it genetic relationship. Keywords : genotypic coeficient of variation, variability, heritability, phenotipic variance.

Abstract

This research explains comparison of effectiveness human urine  with urea fertilizer on the growth of cocoa seedlings (Theobroma cacao, L). This Research use Completely Randomized Design (CRD) with seven treatments, namely: (1) U0 = 2 g Urea, (2) U1 = 50 ml human urine without fermentation, (3) U2 = 100 ml human urine without fermentation, (4 ) U3 = 50 ml fermentation of human urine for 7 days,  (5) U4 = 100 ml fermentation of human urine for 7 days, (6) U5 = 50 ml fermentation of human urine for 14 days, and (7) U6 = 100 ml fermentation of human urine for 14 days. Each treatment was repeated 3 times, thus obtained 21 experimental units.  in this research, parameters measured were seedling height, number of leaves, leaf area, stem diameter, root volume, wet weight, dry weight of plants, the ratio of roots crown, and seed quality index of cocoa seedlings. The data obtained in this study continued using Duncans Multiple Range Test 5%. This study shows that the use of human urine is more effective than the use of urea fertilizer, especially on the use of 100 ml of human urine without fermentation. The use of human urine 100 ml without fermentation, can significantly improve seedling height, leaf number, root volume, wet weight, and quality of cocoa seedlings index. Keywords: cocoa seedlings, human urine, urea fertilizer.
