Abstract

Adaptation test of several rice varieties and dolomit lime on peatland was carried out in the greenhouse of Faculty of Agriculture Riau Islamic University Pekanbaru. The purpose of this research ws to know adaptation power several yielding rice varieties on peatland with using dolomit and to obtain yielding rice varieties which is able to adapt with peatland, and to find a correct dosage by using doomit lime for raise pH soil. The experiment was arranged with grouply randomized design with two factors. The first factor was yielding rice varieties, consisting of four factors: V1 (IR 64), V2 (IR-72), V3 (Kapuas), and V4 (Santani). The second factor was dolomit lime, consisting of four factors: d1 (2.56 t/ha) and PH 5.6, D2 (3.60 t/ha and pH 5.4, D3 (4.51 t/ha) and pH 5.2, and D4 (5.49 t/ha) and pH 5.0. The parameter observed were plant height, number of productive shoot, percetage of unhask full rice, weight of dry rice per hectare, and weight of 1000 seeds. The resuts showed interaction using several yielding rice varieties was not significant effect on the observed parameters. However, the use of yielding varities showed a significant effect with the best variety: V1 (3.9 t/ha), V2 (3.8 t/ha), V3 (3.1 t/ha), and V4 (3.1 t/ha). While, the use of dolomit lime was affected significantly for the whole parameters with the best parameter: D1 (3,6 t/ha), D2 (3,6 t/ha), D3 (3,4 t/ha), and D4 (3,3 t/ha).

Abstract

This research aims to obtain the combination of BAP and NAA concentration which give the best effect on explant growth of Vanda orchid in-vitro. The research was conducted at the biotechnology laboratory Faculty of Agriculture Riau Islamic University Pekanbaru from August to December 2013. The completely randomized design with two factorials (BAP and NAA) was used. The observed parameters included percentage of shoot growing, shoot age, shoot height, shoot number and abnormal embryo somatic. Data were analysed using statistics and BNJ Test at the 5% significance level. The result showed that,interactionally,BAP and NAA applications had a significant effect on height plant with the best concentration without BAP and 1.0 ppm NAA. Individually, the application of BAP effected significantly on percentage of shoot growing, shoot growth, shoot height and shoot number with the best concentration without BAP and 0.1 BAP. Furthermore, the application of NAA influenced significantly on percentage of shoot growing, shoot age, shoot height and shoot number with the best concentration of 1.0 ppm NNA

Abstract

The objective of this research was to know the effect of giving bamboo shot extract and superior plant hormone fertilizer on growth and yield of mung bean. The research was conducted at the experimental farm Faculty of Agriculture Riau Islamic University Pekanbaru. The research was arranged using a completely randomized design with two factorials. The first factor used bamboo shoot dosage (R) with four level treatment: without extract (R0), 1,5 ml/l water (R1), 3,5 ml/l water (R2), and 4,5 ml/l water (R3), and the second factor used superior plant hormone plant doses (H) with four level treatment: without hormone (H0), 2 cc/l water (H1), 4 cc/l water (H2), and 6 cc/l water (H3). The parameter observed consisted of pant height, flower age, harvest age, pod number per plot, pod weight per plot, and weight of 100 seeds. Data analyzed by using statistic and BNJ test at the 5% significance level. Interactionally, the application of bamboo shot extract and superior plant hormone fertilizer showed a significant effect on shoot height and number of pod per plant with the best treatment 4.5 ml/l water of shoot extract and 6 cc/l water of pant hormone. Individually, the application of bamboo shot extract affected significantly on height plant, harvest age, and weight of 100 seeds with the best dosage of 4.5 ml/l water and the application of superior plant hormone fertilizer influenced significantly on pant height, flower age, and pod weight per plant with the best dosage of 6 cc/l water.

Abstract

The objective of this research was to examine the effect of giving Rice MOL and superior plant hormone on growth and yield of Chilli. The experiment was arranged using the completely randomized design with two factors. The first factor was rice MOL (M), namely M0 (without rice MOL), M1 (50 cc/l water), M2 (100 cc/l water), and M3 (150 cc/l water).The second factor was application of superior plant hormone (H), consisting of four factor, namely H0 (without hormone), H1(1 cc/l water), H2 (2 cc/l water), and H3 (3 cc/l water). The parameters observed were plant height, flowering age, the first harvest age, fruit weight per plant, fruit weight per plot, and number of remaining fruit. Data were analyzed using statistical technique and continuing test of BNJ at 5% confident level. The results showed that the interaction of giving rice MOL and hormone had a significant effect on flowering age and harvest age with the best treatment M2H2 with 56.67 days and M2H2 with 112.67 days, respectively. The rice MOL alone gave a significant effect on flowering age, the first harvest age, econmic fruit weight per plant, and economic fruit weight per plot with the best treatment was M2. The superior plant hormone alone affected significantly plant height, flowering age, the first harvested age, economic fruit weight per plant, economic fruit weight per plot, and number of remaining uneconomic fruit per plant with the best treatment of H2.

Abstract

The purpose of this research was to know interaction effect of dolomit lime with tablet urea on peat land and recognize individually way antara dolomit lime and urea fertilizer. This research used the Completely Randomized Design for Factorial which consusted of two factors, namely dolomit factor (D) and tablet urea factor (U). The application of dolomit lime used dose: D0 = without dolomit lime, D1 = 5 g/plant, D2 = 10 g/plant and D3 = 15 g/plant. For tablet urea, the dose: U0 = without tablet urea, U1 = 2 tablets/plant, U2 = 4 tablets/plant, and U3 = 6 tablets/plant. The data were analyzed statistically with different test at the 5% significance level. The observed parameters were plant height, number of productive stem per plant, production per cluster, percentage of dried paddy, and dried paddy yield per ha. The results show that application of tablet urea with dolomit lime intereactionally had not different, but application tablet urea as well as dolomit lime partially had a difference. The best dose was 2 g/plan (U1) for tablet urea and 15 g/plant for dolomit lime. Furtehrmore, the best intereaction was D2U2 treatment.
