Abstract

Soybean seeds deteriorate rapidly when stored under unfavorable conditions and kinetin infusion prior to storage may reduce the rate of seed deterioration. To answer this hypothesis, soybean seeds were permeated with kinetin at 1.0 mM before storage in Agronomy Laboratory on July 2000 at 15 0C and 30 0C for up to 6 months, and their germination, germination after accelerated aging, speed of germination (T50), electrical conductivity and respiration rate were compared with those of untreated seeds stored under the same conditions. The treatments were arranged in a split plot design with three replications. Treated seeds maintained a higher germination and germination after accelerated aging, showed a more rapid germination, a greater cell membrane integrity and a higher respiration rate than untreated seeds irrespective of either storage temperature or storage period, whereas untreated seeds showed a rapid decline in the five seed quality indicators. By four months of storage at 30 0C, treated seeds retained a high level of germination (>80%), medium level of germination after accelerated aging (65%) and a high speed of germination (around 40 hours), while untreated seeds showed a rapid decline in the three seed quality indicators, germination percentage being less than 80%, germination after accelerated aging being less than 50% and speed of germination being higher than 55 hours. Therefore, it is concluded that kinetin infusion prior to storage, in addition to the acceleration of germination, slowed the rate of seed deterioration irrespective of storage temperature through the improvement of cell membrane integrity and seed respiration.

Abstract

The objective of this research was to determine the change of peat nitrogen mineralization rate under influence of peat land transformation on land culture. Four types of peat land transformation were used in this study. They were : low intensive paddy field (STI), high intensive paddy field (SI), dry land crop (LKS), and palm oil plantation (LKT). Four parameters were used to measure the rate of nitrogen mineralized for this necessity : cumulative of nitrate mineralized (Nt), nitrogen mineraliztion potential (N0), half time of mineralization (Tc), and nitrogen mineralization coefficient (K). This research was carried out in laboratory by incubating followed by leaching the peat by using Stanford and Smith (1972) method. The research revealed that the highest intensity of nitrogen mineralization was reached during first to fourth weeks of incubation. On the other hand, the transformation of peat land to culture land enhanced the rate of nitrogen mineralized which was showed by decrease the value of N0 and Tc, while its K value increased. This research showed that control (undistubed peat land) had the highest value of N0 and Tc (44,094 me NO3 100 g-1 peat and 20,586 weeks) and the lowet K value (0,033 week-1); while the lowest of N0 and Tc values and the highest of K value was obtained by peat land that was transformed to dryland crop (GB7).

Abstract

The study was conducted to investigate the effects of cassava and indigofera leaf meals as corn’s substitution on 1 – 5 weeks old quail’s performance. Two hundred and forty of 1 week-old quail were used in the study. Experiment consisted of six treatment groups with eight pen replicates of five quails allocated randomly to each dietary treatment. One group was the control with no substitution while it contains cassava only as corn’s substitution completely and other groups were given cassava and 2.5% indigofera leaf meal as corn’s substitution, cassava and 5% indigofera leaf meal as corn’s substitution, cassava and 7.5% indigofera leaf meal as corn’s substitution and, cassava and 10% indigofera leaf meal as corn’s substituion. The ration used was isoprotein (24%) and isoenergy (2900 kcal kg-1). The result of this study was no significant among treatments (P>0.05) for feed intake. The body weight and body weight gain were significant (P<0.05) where the higher indigofera leaf level the lower body weight and body weight gain. The low body weight gain appropriates best state for layer quail. The ration conversion was significant (P<0.05) where the higher indigofera leaf meal level the higher ration conversion value and it indicates dreadful condition. It is suggested to evaluate the effects on layer period.

Abstract

Puero (Pueraria phaseoloides) which is important legume as protein and mineral source is sensitive to the phosphorus deficiency. However, because of the high cost of superphosphate (SP), the focus is now on rock phosphate fertilizer (RP). Rock phosphate fertilizer, as one of the natural P sources, is relatively cheaper than SP but it slowly available to plants. Fermentation solution of Acetobacter-Saccharomyces (FSAS) maybe a promising technique to overcome this problem. A greenhouse experiment was conducted during 8 weeks on acid latosolic soil and low phosphorus availability. A completely randomized design with 5 treatments, and 4 replicates was used. The treatments were contro, RP, SP, RP+FSAS, and SP+FSAS. Phosphorus fertilizer level was 200 kg P2O5 ha-1 (2.22 g RP per pot or 1.67 g SP per pot). Puero was cut and measured for dry matter (DM), crude protein content (CP), S and Se content on 8 weeks after planting. All data were analyzed by the GLM procedure of SAS. Significant differences among the treatments were calculated by DMRT. The results show that SP+FSAS increased DM production, CP and Se content significantly higher compared to SP (P<0.05). However, RP+FSAS resulted DM production, CP and S content of puero did not difference compared to SP, but Se content significantly higher (P<0.05). Phosphorus fertilization (RP, SP) + FSAS could increase Se content of puero. No differences in DM production, CP and S content were found between RP+FSAS compared to SP fertilization.

Abstract

The research was conducted at Kanigoro Village in Pagelaran Sub-District, District of Malang from May to July 2003. The Objectives of the research are (1) describing the perception of farm household about small scale cattle farm, (2) studying about the factors which influence farm household’s access to cattle in Kanigoro Village. Forty five farmers were selected using purposive random sampling method. Descriptive and economic farming system analysis were applied to the data available. The research found that farm households who kept cattle have perception that rearing cattle could be used for saving, used for land cultivation (i.e brujul) and covered leisure as well. Farm households who did not keep cattle have perception that they had lack of family labour, preferring   to rear other ruminants (i.e goats, buffaloes and milking cows) and did not have enough cash to buy cattle. The factors which influence farm household’s access to cattle were difficulties in accessing feed resources (i.e grass), fluctuated cattle price and difficulties in finding the share holders (penggaduh). Based on these, it is suggested that preliminary research concerning the perception of the local farm households to cattle farming, feed resources and labour availability should be conducted prior to establish an area as the centre of cattle farming development.

Abstract

The research aim was to determine the optimum ratio and flow rate of mobile phase of acetonitrile: water for separation of pesticide residue of imidacloprid, profenofos and deltamethrin simultaneously with HPLC. The compromise wavelength of the three of residues was measured with UV–VIS spectrophotometer. The ratio of acetonitrile:water consisted of 70 : 30, 60 : 40, 50 : 50, 40 : 60 and 30 : 70 v/v, and the flow rate of the mobile phase consisted of 0,5, 0,75 and 1 mL minutes-1, respectively. The results show the optimum mobile phase was achieved at a ratio of 60:40 v/v and at a wavelength of 270 nm with retention tim of imidacloprid, profenofos and deltamethrin components achieved at 3.0, 6.2 and 17.1 minutes, respectively. The higher ratio of acetonitrile: water and higher mobile phase resulted in accelerating its retention time and a good separation of imidacloprid was not achieved. An unstatisfied separation was also obtained when smaller ratio of acetonitrile: water and lower mobile phase was used. It occurred due to higher deltametrin retention time.

Abstract

Two main problems usually faced by corporation including cooperation are fund providing and allocation. KPBS as cooperation and as an economic unit also encounter these problems and has to operate efficiently to gain the profit in order to meet obligation and continuity. However, to attain these aims KPBS faces with fund financing problem and productivity of milk cows. The purpose of this research is to find out the value of financial rate ratios since 1993 – 2002, and compares the financial condition at the same period. The available data be analyzed with financial ratios in consist to Liquidity, Activity, Solvency, and Rent ability. This research show the value of KPBS’s financial performance 1993 during 2002 are: (a) Liquidity ratio, the highest value was 218,96% in 1997 and the lowest was 152,03% in 2002, this condition was still stated liquid because over to 100%; (b) Activity, 73,73 times in the supply period ratio in 2001 was highest then the other years, and the lowest was 4,85 times claim period in 1995 (c) Solvency, the highest value was 386,57% in capital ratio with permanent assets (solvable, because it’s over to 100%), and the lowest value in 1994 at the capital ratio with total assets, it was 36,64%; (d) Rent ability, 19,05% in 1993 was the highest value, and the lowest in 1995 was 0,6%. In case of milk productivity, the volume milk production decrease year by year and has an impact on KPBS financial performance which indicated by Ransum Concentrate (RC) application with protein under national RC standard, that is only 12% from 18% or 75% from 100%. With this condition KPBS should repair RC protein application, and maintaining production price. So that selling price still on breeders expectation.

Abstract

In response to the need of shade tolerant of soybean varieties for agroforestry, we conduct a research to find soybean variety which gave high response to AMF (arbuscular mycorrhizal fungus) and strain of rhizobia inoculation. Research was conducted in a greenhouse by three factor of randomized completely design and replicated three times using top soil of Ultisol from Bengkulu province. First factor was soybean varieties namely Wilis, Pangrango and Ceneng. Second factor was AMF inoculation with Acaulospora sp, Gigaspora margarita, Glomus etunicatum and Glomus manihotis. Third factor was rhizobia inoculation with TEKR 6.29 and KLKR 5.31 strains. Selected AMF and rhizobia isolates was obtained from previous research and taken from the rhizosphere of soybean plants grown on Ultisol of Bengkulu. All replications receive 1 ton ha-1 of farmyard manure and all biofertilizer replication receives 20 kg ha-1 Urea, 20 kg ha-1 SP36 and 60 kg ha-1 KCl. Chemical fertilizer application (80 kg ha-1 Urea, 80 kg ha-1 SP36 and 60 kg ha-1 KCl) used as control. Research result showed that there was a specific combination between soybean variety with AMF and strains of rhizobia. Wilis will gave highest response if paired with Acaulospora sp – TEKR 6.29, Gl. etunicatum – KLKR 5.31, Gl. manihotis- KLKR; Pangrango with Acaulospora sp – TEKR 6.29, Gl. manihotis – KLKR 5.31; and Ceneng with Gi. margarita –TEKR 6.29, Gl. etunicatum- KLKR 5.31, Gl. etunicatum – TEKR 6.29, Gl. manihotis – KLKR 5.31, and Gl. manihotis – TEKR 6.29. Research result also showed that Ceneng gave more consistently response than two other varieties and suitable with every AMF and rhizobia strains tested.
