Abstract

Amendment of soil physical properties on cogongrass field is required for crop production. Objective of this study was determine the physical properties of the soil that was previously populated by cogongrass as affected by cover crops and tillage systems. A split plot design was used to allocate the combinations of conventional tillage and no-tillage system with 5 species of cover crops. Results showed that the properties of soil physic were not affected by cover crop species. No-tillage resulted in lower bulk density, but higher porosity and organic content, compared to conventional tillage.

Abstract

Centrosema pubescens (centro) and Pueraria phaseoloides (puero) are important forage legumes as protein and mineral sources for ruminant livestock in the tropics.   However, most of the land that used for forage production is characterized by a low phosphorus content.   As the high cost of superphosphate is a major limiting factor, a combination of rock phosphate (RP) fertilization and vesicular-arbuscular mycorrhizae (VAM) fungi inoculation maybe a promising technique. A field experiment was conducted in Bogor during 7 months, on a latosolic soil (low pH and low available Bray II extractable P) to evaluate the effects of RP fertilization and VAM inoculation and their interaction on dry matter (DM) production and in vitro dry matter digestibility. A completely randomized block design with 3 replicates was used. The main experiment consisted therein the combination of three factors as follows 1) legume species (centro, puero), 2) VAM inoculation (with, and without VAM inoculation), and 3) rock phosphate fertilization (0, 44, 87, 131, and 175 kg P ha-1).  The period of defoliation was used as sub factor (defoliation I, II, and III).   Results showed that DM production and DM digestibility of puero was significantly higher (P<0.05) compared to centro after defoliation.  Dry matter digestibility of VAM inoculated puero was significantly higher (P<0.05) compared to uninoculated one. Rock phosphate fertilization significantly increased (P<0.05) DM production of VAM inoculated legume. Dry matter production was not significantly different (P>0.05) with or without VAM inoculation.  When inoculated, rock phosphate fertilization increased DM production of legume.   Success of VAM inoculation in the field affected by effectiveness of indigenous- VAM fungi or depending upon VAM inoculum potential.

Abstract

Actually, the system of rice intensifications (SRI) have been encouraging the international researchers, included Indonesians, to intensively increase the yield. The system, such as regulations of planting points, numbers of seedling in each crop point, and planting time were applied here. The research was conducted in Limau Manis, aside the UNAND campus, from January to June 2005 used the varieties of Cisokan. The split plot design was applied in the research. The fertilizers were applied according to the recommended 200 kg urea, 200 kg SP-36, and 150 kg KCl. The research variables are harvest time, productive tillers, numbers of grain per panicle, grain weight, yield component, and yield. The data shows that relatively higher of monthly rainfalls and lower sunny days along the research periods have been the constrains in maximizing the crop production. Simply, the SRI application in the region was significantly useful due to the higher of both crop yield and yield component.

Abstract

[THE EFFECTIVENESS Jatropha curcas (L.) LEAF EXTRACTS IN INHIBIT ROOT-KNOT NEMATODE (Meloidogyne spp.) INJURIES ON TOMATO].  One of the main problems in tomato cultivation is the attack of root purse nematodes (Meloidogyne spp.). Some methods of controlling Meloidogyne spp. which can be done including using plants as vegetable nematicides. This study aims to get the concentration of Jatropha leaf extract which is effective in inhibiting the Meloidogyne spp attack on tomato plants. This study used 48 plants, 24 plants for observation 35 days after planting and 24 plants for observation until the age of 77 days after planting. This study used a Completely Randomized Design (CRD) with the treatment of Jatropha leaf extract concentrations (0%, 10%, 20%, 30%, 40%, 50%), and repeated four times. The results showed Jatropha curcas extract in inhibiting the attack of root purse nematodes (Meloidogyne spp.) can maintain plant height, fruit number, fruit weight, and plant stover wet weight 35 days after planting, but no significant effect on stover wet weight plants 77 days after planting and dry weight of plant stover 35 days after planting and 77 days after planting. The concentration of Jatropha leaf extract tends to increase the concentration, the smaller the rate of infection and the population of Meloidogyne spp on tomato plants. The concentration of Jatropha leaf extract 35% - 45% is the optimum concentration in inhibiting Meloidogyne spp. on tomato plants.

Abstract

[ELIMINATION OF Pineapple Mealybug Wilt-associated Virus (PMWaV) FROM PINEAPPLE PLANT BY HOT WATER TREATMENT]. Mealybug wilt of pineapple (MWP) is a devastating disease found in all the major pineapple growing regions. Closterovirus particles can be detected in both MWP symptomatic and asymptomatic pineapple. Rogue of symptomatic plants is the simplest method of controlling MWP disease, but this method is less effective as PMWaV might remains at asymptomatic plants. Use of pesticide to control mealybug and ants is not efficient and high cost. The research was conducted to develop elimination method for PMWaV-free plant by hot water treatment. PMWaV infected plant parts (leave, stem, crown) were exposed to two hot water treatments, consisting of 35 ºC for 24 hour as pre-treatment and immediately followed by hot water treatment either 56 ºC for 60 minute or 58 ºC for 40 minute in a water bath. The infected plant without hot water treatment served as the positive control, and healthy plant without hot water treatment as the negative control. PMWaV infection could be eliminated from propagative material through hot water treatment 58 ºC 40 minute in a water bath without decrease propagative material viability.

Abstract

One of the most important parameter of climatic water balance computation is crop coefficient (Kc). Unfortunately, the Kc is one of the most difficult parameter to measure in the field. This paper attempts to determine the crop coefficient by using climate observation data and the NDVI (Normalized Difference Vegetation Index) derived from NOAA (National Oceanic and Atmospheric Administration). Calculation using Morton’s Complementary Relationship Areal Evapotranspiration (CRAE) method that used elevation (m), annual precipitation (mm), monthly air temperature ( C), sunshine duration (%), as minimum requirement data, has been applied for more than 900 climatic stations over the Asian region that well documented by FAO-CLIM agroclimatic database to obtain the Kc value. The result was then related to NDVI derived from spectral reflectance of NOAA/AVHRR data. The relation results of NDVI and crop coefficient gave significant linear equation as Kc = 0.08 + 1.83 NDVI, with average correlation coefficient 0.72. It was high over humid area such as in Java island of Indonesia; on the other hand, it was low in semi arid area, such as west part of India. Even the results above were fit only for a specified area; this study has demonstrated a potential use of NOAA image for supplying the crop coefficient value that would be particularly necessary to determine actual evapotranspiration.

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 objective of this experiment was to determine the optimum concentration of 6- benzyl amino purine (BAP) and 1-naphthalene acetic acid (NAA) for in vitro regeneration of diseases-free plantlets of ginger. Meristem part of ginger rhizome selected from infected area was used as plant material. The explant was cut into 0.5 cm3 and, then, cultured in an MS basal medium supplemented with combination of treatments. The experiment wasarranged in Completed Randomized Design with factorial arrangement of the treatments. The first factor was BAP concentrations (0,1,2,3,4 and 5 ppm of BAP), and the second factor was NAA concentrations (0,1,2,3,4 and 5 ppm of NAA). The experiment was done in 18 sterilization methods and planting techniques to regenerate disease-free plantlets. The results showed that supplements of BAP and NAA affectedin vitro plantlet regeneration of ginger. Additional BAP and NAA on the basal media improved percentage of root, shoot and plantlet formation about 83.33- 100%. The highest number of shoot was obtained on 4 ppm of BAP and 3 ppm of NAA, while the highest number of root was obtained on media with addition 3.58 ppm of BAP and 5 ppm of NAA. Supplementing the medium with 3-4 ppm of BAP and 3 ppm of NAA was the best combination for regenerating plantlets of ginger. Microscopic test of micro-rhizome cell showed that there was only 2% of sample infected by P. solanacearum. This result indicated that in vitro technique could be used as an alternative method to produce a disease-free rhizome of ginger.
