Abstract

ABSTRACT The objective of this study was to examine hexagonal plant spacing on growth and yield of three varieties of rice. In addition, this study was also aimed to examine interactions between the hexagonal plant spacing and the varieties on growth and yield of rice plants.  The experiment applied a split plot design with four replications. Factors studied were (1) variety, placed as a main plot and (2) hexagonal plant spacing, placed as subplot. The results showed that effect of plant spacing on productive tiller number varied, depending on variety. In Pandan Wangi and Ciherang varieties, productive tiller numbers did not differ between plant spacing of 21 cm from a spacing of 25 cm. In contrast, in line Cot Irie, productive tiller of 25 cm plant spacing outnumbered that of plant spacing of 21 cm. Effect of plant spacing on panicle length was consistent on all varieties tested. Rice panicle length did not differ between plant spacing of 21 cm and 25 cm. Effect of plant spacing on potential yield per hectare was also consistent across all varieties tested. Plant spacing of 21 cm provided a potential yield per ha which was not significantly different from plant spacing of 25 cm. Line Cot Irie provided panicle length better than varieties Pandan Wangi and Ciherang. Line Cot Irie also provided the highest yield potential per hectare, while panicle length and potential yield per ha of Ciherang were not significantly different from Pandan Wangi.

Abstract

The purpose of this study was to obtain an effective concentration of the extract of sweet flag rhizome in controlling S. litura. This research was conducted at Laboratory of Plant Pests and Diseases, Agriculture Faculty, Syiah Kuala University, Banda Aceh. This research used a Completely Randomized Design (CRD) non-factorial, with six levels of extract concentrations, that is 0%, 3%, 6%, 9%, 12%, and 15%. Each treatment was repeated four times. The variables measured were mortality of larvae, percentage of formed pupae, percentage of emerging imago, and life length of imago. The results showed that application of the sweet flag rhizome extract affected mortality of larvae, formed pupae, emerging imago, and life length of imago S. litura. Use of sweet flag rhizome extract with a concentration of 3% was effective in controlling S. litura. Application of sweet flag rhizome extract with a concentration of 3% resulted in larval mortality up to 57.50%, formation of pupa only 20%, emerging imago 5%, and average life length of imago S. litura 1.25 days.

Abstract

The objectives of this research were to study physiological and chlorophyll changes during seed ripening and find quick parameters as indicators to determine seed physiological maturity level. A randomized completely block design with 5 treatments and 3 replications was used in this research. The treatments were (1) dark green fruit, 42 days after anthesis (DAA), (2) yellowish green fruit, 47 DAA, (3) fully green fruit, 52 DAA, (4) brownish yellow fruit, 57 DAA, and (5) dark brown fruit, 62 DAA. The results showed that jathropa seed was physiologically mature at 57 DAA with criteria: fruit color was brownish yellow, fruit skin was soft and easily hand-opened, and seed was black. These were also supported by seed dry weight, germination percentage, germination rate and first count germination. There were negative relationships between seed chlorophyll content and germination percentage, germination rate and first count germination.

Abstract

The study, aimed at investigating effects of several types of leaf juice liquids on growth of endophytic fungi Trichoderma sp. in vitro has been carried out in Laboratory of Plant Pathology, Faculty of Agriculture Unsyiah, Banda Aceh. The study started with preparation of liquids squeezed from leaves of four types of plant: cocoa leaf, maranggo tree, neem, and lead tree.  Experiment  used a completely randomized design non faktorial, consisted of 5 treatments and 4 replications. Variables measured were incubation period of spores, spore colony diameter, spore color, and spore number. Results showed that treatment of several types of leaf juice liquid exerted a highly significant effect on incubation period and spore colony diameter of fungi Trichoderma sp. The fastest incubation period (2.25 days) and the longest colony diameter (9.00 cm) were found at juice liquid of lead tree leaves. The longest incubation period (3:53 today) was found at cocoa leaf juice likuid, while the shortest colony diameter (4.98 cm) was found at juice of maranggo tree leaves. Use of all liquid leaves in various media did not affect spore numbers, although the media with juice of lead tree leave had more Trichoderma sp. than that of other media.

Abstract

The study was aimed at determining effect of mulch type and concentration of liquid organic fertilizer Super Bionic on growth and yield of onion.  The experiment used a randomized complete block design (RCBD) 3x3 with 3 replications. There were 2 factors investigated, 1) type of mulch consisting of 3 levels: straw, burned husk, and water hyacinth and 2) concentration of organic liquid fertilizer Super Bionic consisting of 3 levels: 2 cc/L of water, 4 cc/L of water and 6 cc/L of water. The results showed that the type of mulch significantly affected the number of tubers per hill, but did not exert significant effects on plant height and number of tillers at ages 15, 30 and 45 days after planting (DAP), wet weight of tuber per hill and dry weight of tubers per hill and potential yield.  Growth and yield of onion tended to be better at water hyacinth mulch. Concentration of  liquid organic fertilizer Super Bionic significantly affected the number of tillers at age 15, 30 and 45 DAP and dry weight of tuber per hill, but did not exert significant effects on plant height at age 15, 30 and 45 DAP, the number of tubers per hill, wet weight of tuber per hill and potential yield. Better growth and yield were obtained at concentrations 2 cc/L of water. There was no significant interaction between type of mulch and concentration of liquid organic fertilizer Super Bionic.

Abstract

A study was carried out to attempt accelerating growth of teak stump by stem cutting and inoculation of Mycorrhiza. Three months-old-seedlings of teak were cut and inoculated with mychorryza. Results of the study showed that growth of teak stump, including stem height, plant height, stem diameter, numbers of leaves, length of leaves, and fresh weight of the teak plant were significantly affected by cutting stem and inoculation of Mycorrhiza. We found that length of stem, length of plant, stem diameter, numbers of leaves, length of leaves were of significantly-positive responses to stem cutting. Additionally, inoculation of Mycorrhiza also successfully accelerated growth of teak stump, including stem, leaves, and biomass. This study found a non-significant interaction between the cutting stem and inoculation of Mycorrhiza. The present study revealed that the cutting stem 2.5-7.5 could be considered as the optimum treatment to enhance growth of teak stump. Moreover, inoculation of Mycorrhiza with 2.5 g/polybag was the optimum dosage to enhance growth of teak stump. The dosage of Mycorrhiza inoculation did not depend on length of cutting stem.
