Abstract

Chrysanthemum cultivation in medium height plains is still facing obstacles where the agronomic properties are not as good as in the highlands. It is important to find cultivation techniques that can improve agronomic properties of chrysanthemum. The setting of additional lighting technique remains to be learned then applied at planting chrysanthemum plain medium. The research purpose is to determine the best additional length of radiation for the improvement of agronomic properties of chrysanthemum. In addition to determining the best chrysanthemum varieties to be developed in the medium height plain as Hargobinangun. The research has been conducted in Hargobinangun, Sleman in April-August 2011 in two stages. The first stage is to determine the length of the addition of irradiation to improve the agronomic properties of chrysanthemum, namely 2,3,4 and 5 hours in the evening starting at 22:00 pm. While the second stage is to look at various kinds of flower faselife varieties, namely Sakuntala, Snow white, Wastu kania, Shamrock, Puspita Nusantara, Padmabuana and Tirta ayuni. The results was showing that cultivation techniques with the addition of irradiation for 5 hours will improve agronomic traits such as chrysanthemum plant height, stem diameter, flower diameter, flower number and brightness of flower color ribbon. While the flower varieties that have good prospects to be developed in the plain medium Hargobinangun because it has a much longer period of flower freshness is Puspita Nusantara, Sakuntala and Snow White.Key words: chrysanthemum, additional lighting, faselife of flowers

Abstract

The application of synthetic growth hormones for rooting of chrysanthemum stem especially in rural area is expensive, therefore, alternative natural compound should be found to replace the synthetic hormones. The objective of the study was to obtain the natural compound as alternative hormones for rooting of chrysanthemum cutting stem. The experiment was performed in plastic house in Salatiga district, Central Java, located at + 700 m above sea level, during January to February, 2007. The treatments used were two natural compounds, coconut water dan crushed shallot, and one synthetic hormone i.e., Rooton containing 5% Indol buteric acid (IBA), Naphtalene Acetic Acid (NAA) and Indole Acetic Acid (IAA) and aquadest as control. Experiment was arranged in randomized block design with six replications. The variety used was Puspita Nusantara which has yellow flower and spray type. The result of the experiment indicated that application of coconut water, crushed shallot, synthetic hormone increased root number, root length, root weight, and fresh weight of chrysanthemum cutting stem. Both natural compounds, coconut water and crushed shallot were able to promote rooting of chrysanthemum cutting stem effectively as synthetic hormone did.Keywords: Chrysanthemum; Coconut water; Shallot; Indole buteric acid; Rooting cutting

Abstract

The purpose of this experiment was to determine the best nitrogen and kalium fertilizer dosage to increase yields and quality of sweet potato. The experiment was conducted at Bandongan Kulon, Ngablak, Magelang, Central Java Province during the period of May up to October 2005, on latosol soil and 1,300 m height. A factorial experiment of 3×3 factors was employed, where the treatments were arranged in Randomized Block Design with three replicates. The first factor was nitrogen fertilizer dosage that consisted of three levels, i.e.: 46 kg N/ha equal with 100 kg Urea/ha, 92 kg N/ha equal with 200 kg Urea/ha and 138 kg N/ha equal with 300 kg Urea/ha. The second factor was kalium fertilizer dosage that consisted of three levels, i.e.: 60 kg N/ha equal with 100 kg KCl/ha, 120 kg N/ha equal with 200 kg KCl/ha and 180 kg N/ha equal with 300 kg KCl/ha. The result of the research showed that no interaction between nitrogen and kalium fertilizer dosage on the number of tuber per plant, weight of tuber per plant and weight of tuber per sample, but they increased yields quality significantly. Nitrogen 92 kg/ha and Kalium 180 kg/ha produced the highest sucrose contents, Nitrogen fertilizer 138 kg/ha and Kalium fertilizer 60 kg/ha produced the highest tuber starch, Nitrogen fertilizer 46 kg/ha and Kalium fertilizer 120 kg/ha produced the highest β–karoten.Keywords: Nitrogen, kalium, fertilizer, sweet potato

Abstract

Curcuma or Java Turmeric as traditional medicine has given significant contribution in industrial empowerment. The demand increased, following the increase of food and drink industry based on curcuma. Therefore, extensification and intensification in curcuma cultivation was developed, included variety and fertilizer composition. Combination of chemical and organic fertilizer was used to increase the yield. However, the effect of fertilizer to plant disease intensity should be determined. Based on the observation at month 6th, the dominant diseases were Fusarium wilt, leaf spots caused by Phyllosticta sp., Colletotrichum sp. and Gloeosporium sp. The greatest percentage of Fusarium wilt (11.11%) was found in variety Cursina 1 that received organic fertilizer 10 ton/ha, with disease intensity 60.52%; whilst the lowest percentage (0%) was found in Cursina 2 that received organic fertilizer. The greatest percentage of leaf spot was seen in Cursina 2 that was given organic fertilizer, with disease intensity 41.67%; whilst the lowest percentage was found in Cursina 1 that received the combination of organic fertilizer 10 ton/ha, 100 kg/ha urea, 100 kg/ha KCl, and 100 kg/ha SP-36, with disease intensity 18.06%.Keywords: curcuma, disease, fertilizer

Abstract

Like the rest of other agricultural wastes, waste from the process of making biofuels from nyamplung seeds (Calophyllum inophyllum Linn) also contain nutrients that can be utilized by both the soil and the plants and the soil as a source of plant nutrients. This study aimed to assess the nutrient content of the waste seed nyamplung after the process of Biofuel. This research was conducted in the Village District Ngade South Ternate Ternate, and the Laboratory of Soil Science Department of the Faculty of Agriculture UGM. This study used the descriptive method, which collect and analyze data and then interpret the results of laboratory analysis. Observed variables, including oil content and nutrient content of the waste, the content of total N, total P, total K, organic C, and KPK. The results showed that the biofuel seed crop nyamplung (Calopphyllum inophyllum Linn) have oil content of 46.57%, and biofuels from waste plant seeds contain nutrients: total N 1.43% (very high), 47.99% Organic C ( very high), total P 0.35% (very low), 1.30% total K (very low), C / N 33.78 (very high), and 17.93 KPK to 100 g-1 (medium).Key words: oil nyamplung, nutrient waste plant seeds nyamplung
