Abstract

Food is a basic need that the demand is increasing in line with the population growth. A new approach of agricultural development is needed in order to fulfill the food need in the present and the future. The approach is to determine the food security in a region by using the Food Security Atlas. The previous atlas is still in the national scale, so it needs additional researches in the local scale. This study aims to create a map of food vulnerability in the Purworejo district as an input to determine the food security. The parameters used to create the vulnerability map are the percentage of vegetated land area, rainfall anomalies, the percentage of crop failure area due to flood or pests, and land degradation due to erosion. Remote sensing data are used to create the percentage of vegetated land area map, land use map, land unit map, flood and erosion map. All parameters are given values to classify the food vulnerability. The results show that the vulnerable regions are not only in the transition area between hills and plain area, which are in Bruno, Pituruh, Kemiri, Kaligesing, and Loano sub-district, but also in the southern coastal region, which are in Ngombol and Grabag sub-district. Calculation show that the area of food secured regions in Purworejo are 63,11 km2, the secured enough regions are 804.96 km2, while the vulnerable regions are 218,24 km2 .

Abstract

Utilization of organic material in crop farming is one of the methods to exploit the local wisdom in agricultural practice. The research was conducted from June to September 2012 in the research farm, State Islamic University of Sultan Syarif Kasim Riau. The objective of the research was to investigate the effects of organic materials and crop density ? in growth and yield on cucumber. Randomized block design with 2 factors and 4 replications was employed in this study. The first factor consists of three levels organic fertilizer treatments i.e. no fertilizer, poultry manure, and compost of oil palm empty bunch. Second factor comprises of three levels of crop density i.e. 1, 2, and 3 plants per pot).. The results showed that there was significant increase on growth and yield on cucumber with poultry manure treatment compare to that of with compost of oil palm empty bunch. Increasing crop density ? improves the number and weight of cucumber yield per pot, even though, some parameters, i.e. number of leaves, stem diameter, crop dry weight, productive number of branches, cucumber size and cucumber weight per plant were significantly decreased.

Abstract

Soybean is legume plant that has ability to symbiosis with Rhizobium. This process produces nitrogen thus decrease the need of urea fertilizer. The purpose of current research was to investigate the effect of Rhizobium and urea dosage on growth and yield of soybean. The research was conducted in experimental field of Agriculture and Animal Science Faculty of State Islamic University of Syarif Kasim Riau, started from May until July, 2012. Peat soil media and soybean cv. Wilis were used in this study. Randomized Completed Block Design with two factorials and three replications was employed for experimental design, in which the first factor was the Rhizobium (with/without Rhizobium application) whereas the second factor was dosage of urea fertilizer (0, 75, 150 and 225 kg/ha, respectively). The following parameters were observed e.g. plant height, number, weight and diameter of root nodules, flowering time, age of harvest time, number of pods/plant, number of seeds/pod, weight of 25 seeds, weight of dry seed/plant, weight dry plant, weight dry root and colour of leaf. The result showed that Rhizobium application increased the number of pods/plant. Urea fertilizer with dosage of 225 kg/ha increased number of seeds/plant, weight of 25 seeds, weight of dry plant, and weight dry seed. Interaction between Rhizobium and urea fertilizer were significantly different to weight dry root.

Abstract

Planting maize hybrid varieties tolerant to acid soils offers an alternative strategy for improving maize productivity in acid soils. The objectives of this study were to evaluate and select maize hybrids for high yield potential in acid soils. Fifteen single maize hybrids derived from a 6 x 6 diallel cross, six parental inbred lines and two chek varieties were evaluated in Ultisol at UPT Farm, Andalas University. The evaluations were carried out in a RCB design with three replications. Several hybrids had high yielding potential in acidic soils as the hybrids produced higher yield compared to Sukmaraga as a tolerant check variety. The results from combining ability analysis showed the preponderance  of non-additive gene actions in the control of yield in acid soils. The hybrids performed high and significant specific combining ability and also higher mid-parent and better parent heterosis, indicating that the heterosis breeding may be rewarding. Hence, it is suggested that these promising hybrids should be further tested before it is released as new hybrid varieties.

Abstract

Ultisol have low fertility, the sub soil of ultisol have fertility and organic matter content are very low. Compost of oil palm empty fruit bunches (OPEFB) and humic acid are useful improving fertility and organic matter content so that it can support growth of the plant. The research aims to study the effect of application of compost OPEFB and humic acid on sub soil ultisol to growth of the oil palm seedling’s in the main nursery. The experiment was conducted at the Experimental Farm of the Faculty of Agriculture, University of Riau, Pekanbaru. The experiment were carried out in the form of factorial with a completely randomized design. The first factor is compost of OPEFB that consists of 4 levels (0, 25, 50 and 75 g/polybag) and as the second factor is the humic acid that consists of 3 level (0, 25 and 50 g/polybag). The parameters observed were statistically analyzed using analysis of variance, followed by Duncan’s multiple range test at 5%.The parameters measured were plant height, in the number of leaves, the increase in diameter stump, root crown ratio, dry seedling weight. The results slowed that the application of compost of OPEFB 25-75 g/polybag followed by humic acid 25, 50 g/polybag significantly increased plant height, in the number of leaves, the increase in diameter stump, root crown ratio, dry seedling weight composed than without compost OPEFB and humic acid, but now significantly with the other combination action.

Abstract

One of the problem of Eurycoma longifolia Jack propagation was low germination percentage due to recalcitrant seeds and slow growth of seedling from cutting propagation. To overcome this problem is required propagation of Eurycoma longifolia via in vitro culture. The objective of this research was to know the effect of Auxin (2,4-D and NAA) and Cytokines (BAP and Kinetin)  on Eurycoma longifolia callus induction via leaf and petiole explants. In this study, we used plant growth regulator of 2,4 D, NAA, BAP and Kinetin in several levels.  The observed variables were appearing callus time, callus color and callus texture. The results of this study showed that MS medium supplemented with 1 ppm NAA+ 1 ppm BAP was able to induce callus formation in leaf explant for 6 months after culture. While MS medium supplemented with 1 ppm 2,4-D, 1 ppm BAP, combination of 2,4-D and Kinetin and combination of 2,4-D and BAP can induce callus formation from petiole. All the callus formation has yellow color and yellow brown color. The petiole explant that is grown in MS medium supplemented with 1 ppm BAP induced of callus in short time (18 days after culture).

Abstract

The Loss of crop productivity can reach 30-35% if not use pesticide. The other hand, to use of pesticides can be caused environmental problems and human healthy. This research aims to develop biopesticides for pests and plant diseases. It was conducted at the PEM laboratory UIN Suska Riau and on land, from July to November 2015. The sourches were extracts from Andropogon nardus, Annona muricata leaves, Ageratum conyzoides, Piper aduncun fructus, Nicotiana tabacum leaves, Tinospora crispa, Azadirachta indica leaves, Allium sativum and Piper betle leaves. Each the source was macerated in alcohol 50% for 24 hours and then distilled at a temperature of 60 °C until all the alcohol evaporates. The experimental Design was complete random design with 7 treatments (control, 20%, 40%, 60%, 80%, 100% and chemical pesticides as positif control) and 3 replicates. Parameters of the test biopesticides to disease performed in vitro with measure the resistance zones and for mealybugs and Gryllus assimilis in vivo with the pest mortality. Biopesticide test in vitro for the bacteria that causes carrot root rot has not been able to kill microbes. The mortality rate mealybugs begins before 1 hour observation at the treatment biopesticide concentration of 80%, 100% and control positif.  Provision of different concentrations of biopesticides, does not the increased mortality of Gryllus assimilis. This shows that the power to kill biopesticide still well below chemical pesticides, but the pest is still alive no appetite as antifeedant effect of the biopesticide. So biopesticide application does not have to kill the target pest. Need  follow-up and development of this research and other pests.
