Abstract

The aim of this study was to measure the resistance of several sweet potato genotypes to C. formicarus Fabricus (Coleoptera: Curculionidae) attack. The design used in this study was a randomized block design (RAK) with 9 treatments and 3 replications, so that 27 experimental units were obtained. The genotype treatmens were Antin 1, Antin 2, Antin 3, Koya 2, Koya 4, Koya 6, Beta 2, Kidal, and Salosa. The results of the analysis showed that all of the tested genotypes were naturally damaged by C. formicarius pests both at the base of the stem and on the tubers. The intensity of tuber damage caused by C. formicarius among 9 tested genotypes was the highest in the Salosa genotype (17.593%) and the lowest was in the Antin 1 genotype (5.553%). The intensity of damage to the base of the stem caused by C. formicarius among the 9 genotypes tested was the highest in the Antin 1 genotype (61.110%) and the lowest was in the Left-handed genotype (47,333%). Colonization (infestation) of C. formicarius in the test genotype occurred from the beginning of the observation at 4 week until the plants were harvested (tubers formed). The egg and larvae populations in this study were not found, while the number of imago from each test genotype was different with the highest population was in the Antin 1 genotype (3,3200 individuals), then the lowest imago population was in the Antin 3 and salosa genotypes with an average value of 2.1467 individuals. The resistant genotypes were Koya 4, Salosa, and Beta 2, while genotypes that were moderately resistant were Koya 2, Kidal, Antin 3, but Antin 2, Koya 6 and Antin 1 were sensitive genotypes.

Abstract

This research aimed to study the effect of garlic extract on the growth of stem cuttings of several types of bougainvillea and used a factorial randomized block design (RAK) with two factors. First factor is garlic extract in 2 levels, (with or without garlic extract). Second factor 2 is the type of bougainvillea consisting of 5 varieties such as yellow flowers, dark purple flowers, white flowers, red flowers and orange flowers. The results showed that the interaction between onion extract and bougainvillea had no significant effect on all observed variables (sprouting time, number of shoots, shoot length, number of roots, root length, percentage of cuttings sprouted and percentage of rooted cuttings). Garlic extract had no significant effect on all observed variables. There was a tendency for cuttings given garlic extract to show a faster age of budding, more shoots, longer roots and more roots. The type of bougainvillea gave a very significant effect on all observed variables except the number of shoots. Red flowers show the earliest age to start sprouting (16.80 days), the longest shoots (26.03 cm) and the longest roots (9.43 cm). Orange flowers performed the highest number of shoots (4.79), the highest percentage of shoots (96.67%) and the highest percentage of roots (96.67). Yellow flowers showed the latest sprouting time (37.08 days), the shortest shoot length (2.51 cm), the shortest root length (1.56 cm), and the least number of roots (1.06). Dark purple flowers showed the lowest percentage of budding and root percentage (63.33%).

Abstract

The objective of the experiment was to observe the effect of several dosages of coarse grass compost to the yield of tomato. The experiment was conducted from December 2007 to May 2008 at Jambi University experimental station, which located in an altitude of 35 m above the sea level. The experimental design was randomized complete block design with 4 replications and 6 treatment level of dosages of coarse grass compost, ie.: a0: 0 ton ha-1 (no compost), a1: 5 ton ha-1, a2: 10 ton ha-1, a3: 15 ton ha-1, a4: 20 ton ha-1 and a5: 25 ton ha-1. The results showed that dosages of coarse grass compost significantly affected fruit set per plant, number of fruit per plant, fruit weight per plant, but no significantly affected age of the first flower initiation and age of the first harvest. The dosages of coarse grass compost on 25 ton ha-1 gave higher fruit set per plant, number of fruit per plant, fruit weight per plant than other treatments.

Abstract

This objective of the study is to determine the effect of potassium nutrition on stomatal aperture and drought resistance. Research has been conducted in the greenhouse of the Faculty of Agriculture, Gadjah Mada University in March-May 2012. This experiment was arranged on Factorial Completely Randomized Design (RAKL). The first factor was KCl consist of three level thoose are 0 kg ha-1, 50 kg ha-1, and 100 kg ha-1. The second factor was water consist of four levels which wereenough water and less water. Parameters observed were periodic observations on plant height while the observations made at the first harvest and the end covers root dry weight, shoot dry weight, total dry weight, leaf area, stomatal aperture and proline compound content. The results showed that potassium fertilization affect proline levels in maize, proline accumulation also significantly affected by water deficit conditions. The relationship between stomatal aperture width is closely related to water stress conditions that can increase the accumulation of proline.

Abstract

This objective of the study is to identify the type of insect pestof 10 soybean varieties. The study used descriptive method with field observation technique, whichthen continued by deviation standard measurement. The data were analysed in tabulation, while the insects pest were identified by using insect manual book. The variable of observation were insect pest type, the forms of damaged, the weight of full and empty pod, the number of trunk, fresh weight, dry weight and plant height. The result shows that there are 8 types of main insect pest of soybean such as Ophiomya phaseoli, Lamprosema indicate, Chryzodeixis calcites, Phaedonia inclusa, Spodoptera litura, Nezara viridula, Riptortus linearis and Phiezodorus hybneri. Ophiomya phaseoli is the most insects found in the soybean plants for about 151, following by Riptortus linearis for about 52 and Phiezodorus hybneri for about 32. Among the 10 soybean varieties, Grobogan, Wilis and Kaba were found to be resistant to the pod borer insects pest while varieties resisted to the stem borerinsect pest were Grobodan, Prafi and Kaba. The highest productivity resulted from Cikuray and Anjasmoron which still attacked by the insects.
