Abstract

An experiment to evaluate the dwarfness and the drought tolerance of 97 rice varieties/lines, collected from various source institutes surround West Java has been executed at Muara Research Station, Bogor in 2009. Any varieties/lines could be stated as drwarf when it has harvest time of 90 – 104 days. Meanwhile, it could be stated as drought tolerance when the line was scored 1 (tip of the leaves dryied) and has growth recovery respons of more than 90%. The dwarfness test showed that the tested varieties/lines had a varied 50% flowering time, ranging from 58-104 days after seeding (DAS). Amount of 29 out of 97 lines/varieties could be classified as very dwarf lines/varieties, with 50% flowering time of 67-79 DAS. This means that those lines/varieties could be harvested at the age of 92-104 DAS. However, those lines/varieties were also identified to have various performance score, i.e. ranging from 1-7. Several lines/varieties with good dwarf ness characteristic are OM AS996 (76 DAS; PAcp 1), OM CS2000 (73 DAS, PAcp 3), MUDGO (67 DAS;PAcp 7), dan OM 1490 (76 DAS, PAcp 3). Two lines/varieties (OM 1490 and B11742-RS*2-3-MR-34-1-1-3) was identified to be the most drought tolerance lines. Meanwhile, 11 lines/varieties were graded as tolerance to drought  lines, with ability of growth recovery 90%. They were Sensari, Goarsail, OM 4498, OM 2395, B11742-RS*2-3-MR-34-1-1-4, S4616, OM 2514, Meraoke, Mira-1, Bestari, and B11742-RS*2-3-MR-34-1-4-3. Based on those tests, it was found that rice lines of OM 1490, OM 4498, OM 2395, B11742-RS*2-3-MR-34-1-1-3, B11742-RS*2-3-MR-34-1-1-4, and B11742-RS*2-3-MR-34-1-4-3 were the most suitable parental lines in the development of such rice varieties.

Abstract

The use of multiple kinds of fertilizers on edamame plants have been conducted in Lampung State Polytechnic aims to see the growth and yield of fresh edamame pods varieties of Rioko are planted using four different types of fertilizer. The experiment was arranged in a randomized complete block design. Treatments consisted of four kinds of fertilizers, ie P1 = cow dung manure 20 ton.ha -1, P2 = chemical fertilizers (100 kg Urea.ha-1  + 150 kg SP36.ha-1 + 150 kg KCl.ha-1) ; P3 = 100 kg Urea.ha-1 + 150 kg SP36.ha-1 + 150 kg KCl.ha-1 + 20 ton.ha-1 cow dung;  and P4 = Fertilizer Nadira 12 ton.ha-1. Each treatment was repeated three times. Data were analyzed by variance. If there are differences among the treatments used is followed by Least Significant Difference Test (LSD) at 5% level. The results show the four types of fertilizer used is not significantly increased plant height, number of pods per plant, weight of 100 grains of fresh seed and pod weight per plant, but significantly increased the number of branches per plant. Cow manure 20 ton.ha-1 performed better than 12 ton.ha Nadira-1 and combination of chemical fertilizer + manure.

Abstract

Yambean mosaic virus is the most important virus infecting yam bean in Indonesia. The virus were transmitted either mechanically or via aphid.  This study to test the transmission efficiency of the virus via A. craccivora and A. gossypii by using different number of aphid such 1, 3, 5, 7, and 10 for each treatment. To determine the transmission efficiency, incubation period, type of symptom and incidence were used as parameter. Transmission of virus by A. craccivora showed incidence range 90 to 100%, significant differences in incubation time of 1 aphid compared to other treatments and showed severe leaf mosaic, vein-banding and severe leaf malformation such as string. However, the incidence of transmission of virus by A. gossypii was range 70 to 100%, with longer incubation period in compare with A. craccivora. There was no significant differences of incubation period among treatments by A. gossypii. The infected plants showed leaf malformation, vein-banding, wrinkle and blotch on the leaves. Based on these, both aphids species could transmitted virus efficiently, and among them A. craccivora considerate has higher ability as efficient insect vector to transmit the virus in compare with A. gossypii.

Abstract

Gotu kola (Centella asiatica L.) is one of the medicinal plants widespread in the tropics and subtropics. Gotu kola plant has long been used as traditional medicine to cure various diseases. One of the chemical constituent beneficial to this plant Centella asiatica is triterpenoids. The Objective of this research is to observe the effect of shade and cow manure on growth and triterpenoid content of gotu kola. The research was arranged using Split Plot Design with 2 replications. Main plot is shading level consists ie without shade (0%) and shade of 30%. The subplot was the dosages of cow manure that is, without fertilizer, 20 tons/ha and 30 tons/ha. Components of growth and production observed at 4 plant selected of each plot treatment. Observations of growth include the number of leaves, number of stolon, petiole length per plant was observed at 14, 28, 42, 56, 70, 84, 98, 112 and 124 days after transplanting (DAT) and production components include leaf area, fresh weight, dry weight and content of triterpenoids were observed the end of the study (124 HST).  The results showed  there is interaction of shading level and cow manure with different doses on the number of leaves at the age of 84 HST observations (the highest value N0P0 = 609 leaves), stolon number of observations at age 14, 42, 56, 70, and 84 HST ( The highest value N1P0 = 49 stems), petiole length at the age of 70 HST observations (the highest value N0P0 = 14.8 cm), leaf area at the age of 124 HST observations (N1P2 = 3.92 cm2), the content of triterpenoids at the age of 124 HST observations (the highest value N0P2 = 18.00 mg / kg), but have no effect on the wet weight and dry weight. Treatment combinations reduced  number of stolon and leaves, but increased stem length and leaf area compared with control. Dosages of 30 tons / ha cow manure fertilizer gave a higher fresh weight than the other treatments.

Abstract

The aims of the experiment were to study the effect of Compound Biofertilizer (CB) and Rock Phosphate (RP) on the several soil chemistry properties of Andisols as well as the P-uptake by lettuce. The research had been conducted in the greenhouse of Agriculture Faculty, Unsoed at Karangreja, Purbalingga, since May up to August, 2009. The experiment was arranged in factorial 4 x 4 based on Completely Block Randomyzed Design with three replications. The firsrt factor was the concentration of CB consists of 4 levels, i.e. 0, 1, 2 and 3 %; and the second factor was the dosage of RP consists of 4 levels, i.e. 0; 25, 50 and 75 kg P2O5 per hectare.  The variables observed were the soil pH, exchangeable aluminium, the availability of P, P-uptake by plant, plant height, number of leaf, fresh weight of plant and dry weight of plant. The data collected was analyzed using Fisher and DMR-test. The results indicated that the application of 75 kg P2O5 of RP could increase soil pH, reduce exchangeable-Al, increase the availability of P in the soil, P-uptake by plant, the fresh weight and dry weight of plant. The application of 2% concentration of CB could reduce exchangeable-Al, increase the availability of P in the soil, P-uptake by plant, the fresh weight and dry weight of plant.
