Abstract

Sandy coastal area is a poor land, with minimal nutrients and low ability to store water and nutrition. Therefore, plant is difficult to grow well, consequently the treatments for improving sandy coastal is required before planting to support their growth. Application of Trichoderma as a plant-growth promoting and controlling pathogens had been known. Shallot seed treatment by Trichoderma agents was intended to improve and support plant growth and yield in the sandy coastal land. The aim of experiment was to determine the most effective treatment to improve growth and yield of shallot on sandy coastal land. The experiment had been carried out in Yogyakarta during August - November 2015. The factorial treatments of cultivar and Trichoderma applications were arranged in Completely Randomized Design with three replications. The shallot cultivars consisted of Tiron, Crok, and Biru, while Trichoderma application consisted of control (no treatment), sprayed with Trichoderma, soaked in Trichoderma, matricontioning media i.e. rice husk charcoal and brick in combination with Trichoderma. The collected data related to plant growth and yield. The result showed that seed treatment methods with Trichoderma increased the plant height, the leaf area index, extensive root, net assimilation rate (NAR), plant growth rate (PGR), Nitrate Reductase Activities (NRA), total chlorophyll, and fresh bulb weight. The best technical treatment for cultivar Tiron was soaked with Trichoderma, and Crok was sprayed with Trichoderma, while Biru cultivar was using brick in combination with Trichoderma.

Abstract

Fusarium wilt caused by Fusarium oxysporum f.sp.cepae (Foc) is one of the most important diseases of onion in Indonesia. Induced resistance was one of the effective techniques to acquire resistance to fusarium wilt in shallot. Salicylic acid (SA) had been inferred to be in endogenous signal in the systemic acquired resistance response of plants. This research aimed to study the effect of exogenously added SA to resistance in shallot callus cv ‘Bima Brebes’ to fusarium wilt disease in vitro; and to determine the effective concentration of SA to induce resistance. A group of shallot callus was grown in MS medium containing varying SA concentration (0, 15, 20 and 25 ppm) in vitro for 2 weeks. Then, the callus were treated with toxin of Fusarium oxysporum, namely fusaric acid, to have observe the resistance response. In vitro selection was done twice in different fusaric acid concentration. Application of exogenous SA at all concentration did not suppres time of appearance of disease symptom yet. Toxic symptom in the callus was shown by the browning or blackening (off) of callus. Salicylic acid at concentration of 20 ppm effectively reduced the toxic symptom up to 16.66% and supported callus regeneration better than the concentration of 15 ppm and 25 ppm. The number of resistant callus regenerated was 66.67% at pretreatment of 20 ppm of SA.

Abstract

Curly red chili was one of vegetable commodities in Indonesia used for seasoning of home cuisine, food industry, and pharmaceutical industry. Curly red chili cultivation needed fungicide to prevent fungal disease. Pyraclostrobin was a fungicide which could overcome fungal attack and improve plant growth. This research was conducted to study the effectiveness of pyraclostrobin application on vegetative growth of curly red chili plant. Research had been done in farmer’s land in Kemiriombo Village, Dukun Sub District, Muntilan District, Magelang Regency from December 2013 to June 2014. The treatments were assigned in the Randomized Complete Block Design with three replications. The treatments consisted of P1: pyraclostrobin doses 1.5 kg ha-1, 30 and 90 days after planting (dap), P2: pyraclostrobin 1.5 kg ha-1 at 30, 60, and 90 dap, P3: pyraclostrobin 1.5 kg ha-1, at 15, 30, 60, and 90 dap, P4: pyraclostrobin 3 kg ha-1, at 30 and 90 dap, P5: pyraclostrobin 3 kg ha-1, at 30, 60, and 90 dap, P6: pyraclostrobin 3 kg ha-1, at 15, 30, 60, and 90 dap, and P0: control (no treatment). Data were analyzed by orthogonal contrast test with α=5%. The result indicated significant different in the dry weights of root, stem, leaf, and total yield at 12 weeks after planting; number of flower at 9-11 week after planting, 14 week after planting, and 18-21 week after planting; and number of fruits at 10-12 week after planting, 15, and 16 week after planting. The application of pyraclostrobin at all dosages could increase IAA content. The numbers of flower and fruit were influenced by the increasing of IAA content in plant tissue, but did not affect the yield.

Abstract

Nitrogen was a key component for increasing yield and quality of vegetables like shallots. The growth and development of plants were influenced by nitrogen form. Common plants preferred nitrate for growth, but the enormity preference varies within plant species and other environmental factors. The purpose of this experiment was to study the effect of ammonium:nitrate ratio in sandy soil to growth and yield of shallot (Allium cepa L. Aggregatum group). The experiment had been conducted in August-October 2015 in the sandy land on Samas Beach, Bantul, Yogyakarta, Indonesia. The research was arranged in a Split-Plot design. The main plot was the source of nitrogen (NH4+; NO3-; NH4+: NO3- 1:1; NH4+: NO3- 1:2; and NH4+: NO3- 2:1) and the subplot was cultivars (Crok Kuning, Tiron, and Bima Brebes). Each subplot covered an area of 2.5 m² (2.5 m x 1 m) with three blocks as replications. Shallot bulbs were planted in sixth-row, spacing 20 cm between rows and 15 cm within rows. The dose was applied according to the recommendation of BPTP (urea 200 kg ha-1, ZA 250 kg ha-1, SP-36 150 kg ha-1, and KCl 150 kg ha-1) 144.5 kg N ha-1. Ammonium:nitrate ratio influenced shallot growth in sandy soil through number of leaves at maximum vegetative phase and its leaf area. The NH4+: NO3- 1:2 ratio gave the best result in dry weight of leaves following bulb dry weight than other ratio. Nevertheless, ammonium:nitrate ratio had no significant influence on bulb dry weight (ton ha-1).

Abstract

The marginal sandy coastal land should be utilized to maintain production level of shallot. But for increasing the productivity of sandy coastal land, in the shallot cultivation should be applied biological fertilizers, such as Plant Growth Promoting Rhizobacteria (PGPR). The purpose of this research was to obtain the most effective isolate of PGPR (Plant Growth Promoting Rhizobacteria) to the growth of three shallot cultivars in the sandy coastal land. The research had been conducted in August-November 2015 at Samas sandy coastal land, Bantul. The Factorial treatments were assigned in Randomized Complete Block Design with three blocks as replications. The first factor was shallot cultivars consisted of Crok, Tiron and Tuk-tuk, while the second factor was the PGPR suspension, i.e. control (without PGPR), PGPR isolates BP25.2 (Bacillus methylotrophicus), BP25.6 (Bacillus amyloliquofaciens), BP25.7 (Bacillus subtilis), BrSM 4 (Burkholderiacepacia), and BrSG 5 (Burkholderiaseminalis). The data of growth and yield were analyzed using ANOVA with α = 5%, then followed by DMRT α 5% . The result showed that Tiron cultivar was able to grow in sandy coastal land, proven from its good germination, high number of bulb, high fresh weight, and dry weight of bulb. Meanwhile, BP25.2 isolate was able to increase seed growth simultaneously of Tiron cultivar and BrSM 4 isolate was able to increase the chlorophyll content of Tuk-tuk cultivars.

Abstract

BA and 2,4-D combination were commonly used for in vitro culture of Shallot (Allium cepa L. var agregatum 2n = 2x = 16) to induce callus, but there was no information for callus induction on shallot seed (TSS) explant. Callus could be utilized for in vitro selection and generating of genetic variation. The aims of the research was to identify the response of TSS (Trisula and Tuk Tuk) as explant  and to obtain the optimum combination of BA and 2,4-D (mg.L-1): (0–0, 2–1, 2–2, 2–3, and 2–4) in callus induction. The research had been carried out in the Tissue Culture Laboratory, Faculty of Agriculture, Universitas Gadjah Mada during the year 2015-2016. Factorial treatments of variety and growth regulators were arranged in Completely Randomized Design with four replications. Data of percentage of germination, shoot height, root length, percentage of callus formation, callus weight, and chromosomes number of callus were recorded. The results showed that combination of 2 mg.L-1 BA + (1– 4) mg.L-1 2,4-D induced callus formation on TSS but inhibits shoots and roots growth. The best callus proliferation was at a concentration of 1 mg.L-1 2,4-D. Tetraploid callus chromosomes (2n = 4x = 32) was detected in Trisula grown in the 2 mg.L-1 BA + 4 mg.L-1 2,4-D, but in the Tuk Tuk callus did not detected the changing of chromosomes number.

Abstract

Shallot (Allium cepa L. Aggregatum group) is one of the most widely utilized vegetables by Indonesian people. Some technologies have been adapted to improved shallot productivity. One of those are the application of beneficial microorganisms. We applied mycorrhizal fungi, Trichoderma sp., and Bacillus thuringiensis as well as the combination among these microorganisms were applied in Shallots cultivation and were investigated to improve the growth and development of shallot. A field experiment was arranged in a Randomized Complete Block Design with two treatment factors. The first factor consisted of two shallot cultivars, namely Biru Lancor and Crok Kuning; whilst the second factor consisted of six beneficial microorganism treatments, i.e. control, mycorrhizae, Trichoderma sp., Bacillus thuringiensis, the combination of mycorrhizae and Trichoderma sp., and the combination of those three microorganisms. The observation was conducted on infection percentage of mycorrhizae, total population of Trichoderma sp., leaf area, leaf area index, net assimilation rate, crop growth rate, harvest index, and plant yield. The data obtained were subjected to analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT) at 5% significance level. The results showed the leaf area of shallot was improved as affected by the application of mycorrhizal fungi. The effectiveness and implication of mycorrhizal fungi on shallot growth would decrease if the application of was combined with other microorganisms. However, the application of beneficial microorganisms had not been able to increase component yield and yield of Biru Lancor and Crok Kuning, indicated by bulb weight, number of bulb, bulb diameter, number of bulb per cluster, and bulb yield per hectare.

Abstract

Surjan system (alternating bed system) is an agricultural system that combines dry and wet bedding system. It integrates food crop culture in the sunken-bed and annual crops in the raised-bed of the rainfed rice field. In Bantul, farmers commonly apply Surjan system in rice field by growing shallot (Allium cepa L. aggregatum group) and chili (Capsicum annuum L.) in the raised-bed, whereas no crop is grown in the sunken-bed. This present experiment evaluated the utilization of the sunken-bed for rice cultivation by utilizing fertilizer runoff from the raised-bed. Rice plants in the sunken-bed were not fertilized due to the expectation that it could utilize the fertilizer runoff from the raised-bed. The cropping pattern and the fertilizer dose in the raised-bed are suspected to affect the growth and yield of rice in the sunken-bed. The purpose of this study was to determine the effect of cropping pattern and fertilizer dose applied in raised-bed on the growth and yield of rice in sunken-bed of the Surjan rice field. This study were laid out in a split plot design with three replication. The main plot consists of two cropping pattern, namely shallot monoculture and intercropping shallot with chili. The fertilizer dose applied in raised-bed, namely 100% farmer's habit; 50% farmer’s habit; and 25% farmers' habit, occupying the sub plot. Dose of fertilizer applied in riased- bed according to the farmer's habit in research locatin is 622 kg NPK/ha (16-16-16) ; 228 kg ZA/ha and 76 kg KCl/ha. The results showed that there was no interaction between the cropping pattern and the fertilizer dose applied in the raised-bed on the growth and yield of rice in the sunken-bed. Compared with shallot monoculture, intercropping shallot with chili in raised-bed decreased the growth of rice in the sunken-bed. Compared with the 100% fertilizer dosage of farmer's habits, the fertilizer dose of 50% of the farmer's habits in the raised-bed increased the growth of rice in the sunken-bed. Cropping pattern and fertilizer dose in the raised-bed did not significantly affect the rice yield grown in the sunken-bed of the Surjan rice field.
