Abstract

[STABILITY IMPROVENT OF STEEP HILL SOIL STRUCTURE BY MEANS OF HYDROSEEDING OF MOSSES AND SOIL CONDITIONERS]. Steep hill is very sensitive to soil erosion and land slide. The objective of this study was to determine the effects of mosses (musci) and soil conditioners applied through hydroseeding technique on the development moss colony and stability of soil structure of steep hill. A randomized complete block design with three replications was used to allocate the treatment combinations of soil conditioners (no soil conditioner, water + manure, and water + manure + latex) and moss species (no moss, Andrea petrophila, and Polytricum commune).  1m x 1m plots were made on steep hill with 65% inclination and each plot was sprayed with 2 L of the soil conditioner and moss mixture (hydroseeding). Observations were made on the moss development and soil physical properties. The results showed that the moss colony increased significantly as applied with soil conditioners.  The highest colony size of moss was found on the application of water + manure + latex (200.85 m-2), followed by water + manure with (156.46 m-2), whereas no soil conditioner produced the lowest (104.91 m-2).  Hydroseeding of moss and soil conditioner had significantly improved the stability of soil structure . Combination of Polytricum commune and water + manure + latex produced the highest improvement in soil structure stability by 93.3 % as compared to the control.

Abstract

An experiment was carried out to examine the effect of sire and dam on fertility and hatchability of eggs from crossbreeding among Bengkulu (B), Padang (P) and Yogyakarta (Y) quails. Treatments, crosses of BB, PP, YY, BP, BY, PB, PY, YB, and YP, were arranged in a Completely Randomized Design with five replications. The result of this experiment showed that the fertility of sire and dam of Bengkulu pure breed (BB, 77%) were significantly lower than Padang pure breed (PP) and other crossbreeds (BP, PB, PY, YP, BY and YB) but being not significantly different than fertility of Yogyakarta pure breed (YY). Hatchability of BB (71.12%) was not significantly different with hatchability of YY, BY and BP, but it was significantly lower than another croosbreed (PY, YP, YB and PB) and PP. The higher egg fertility and hatchability of crossbreed between Bengkulu quails and those of sire and dam from Yogyakarta or Padang as compared with those of Bengkulu quails pure breed shows potential for larger scales quail egg production. However, further researches need to be conducted to improve egg productivity of the crossbreeds.

Abstract

The rust disease resistance of groundnut has inherited pattern 9 : 7, indicating that was controlled by double resessive genes. From this fact needs an explanation of gene action, so it can be used as information in the breeding system and selection. The purpose of this research is to know the gene action control, if resistant the rust disease in groundnut. The design used in this experiment was randomized block design with three replications. There were 29 genotypes as treatments (5 genotypes parents, 6 genotypes F1, 6 genotypes F2, 6 genotypes BC1.1 and 6 genotypes BC1.2). The result of the experiment showed that there was a gene non-allelic interaction, mean effect (m) and a dominant gene effect (h) in progeny of Muneng x ICGV 87358 (Six Parameters Mode). However, the gene non-ellelic interaction did not occur in other progenies. Meanwhile progenies of Gajah x ICGV 92088, Gajah x ICGV 87358, Gajah x ICGV 91227 had a mean effect (m) and a aditive gene effect (d), and Muneng x ICGV 92088, Muneng x ICGV 91227 had only a mean effect (m).

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

This research aims to monitor soil water content in the field through the measurement of the electrical impedance during the early period of corn growth in the dry season. Two levels of tillage and four types of mulch were arranged at a split plot design with three replications. Part of experiment plot was cultivated twice and the other part was not cultivated. Each main plot was then divided into four sub-plots of 3 x 4 m each of wich was applied with 100% imperata mulch, 80% imperata and 20% kerinyu mulch, 50% imperata and 50% kerinyu, or 100% kerinyu. Two sets of wire, where the lowest 10 cm part was not isolated, were inserted into 10 and 20 cm soil depth therefore they measured the electrical impedance at the 0-10 and 10-20 cm soil layers. The electrical impedance values were measured using the digital ohm-meter that produce the electrical current at frequency of 1 kHz. Results show that the measured electrical impedance values have a very high sensitivity to the fluctuation of soil water content in the field. When calibrated to the same soil, the values can be transformed into water content values. During the measurement period, the cultivated soil is consistently drier at the 0-10 depth and wetter at the 10-20 depth compared to the uncultivated soil. The combination of 50% imperata and 50% kerinyu mulch maintains higher soil water content uring the dry season compared to other combinations. The research suggests that monitoring of soil water content can be conducted directly in the field through the measurement of electrical impedance.

Abstract

[UTILIZATION OF MICROBE TO INCREASE GROWTH AND YIELDS OF SOYBEAN IN COASTAL LAND]. This study aims to obtain the precise combination of variety and biofertilizer to increase soybean productivity in Bengkulu coastal land. The research was conducted from March to July 2017, located at Beringin Raya Village, Muara Bangkahulu Sub-District, Bengkulu. The study was conducted using a split-plot design which was repeated three times. The main plot was two soybean varieties (Grobogan and Wilis). The subplots were two types of biofertilizers, arbuscular mycorrhizal fungi and phosphate solubilizing fungi. The result showed that the seed weight of the Grobogan variety (equivalent to 3.38 tons/ha) was significantly higher than the Wilis variety (equivalent to 2.72 tons/ha). However, the increment of the Wilis variety (equivalent to 1.12 tons/ha) was higher than the Grobogan variety (equivalent to 0.61 tons/ha) according to the description of each variety. The combination of arbuscular mycorrhizal fungi and phosphate solubilizing fungi showed superior performance than arbuscular mycorrhizal fungi or phosphate solubilizing fungi alone. The interaction of Grobogan varieties with a combination of arbuscular mycorrhizal fungi and phosphate solubilizing fungi produced the highest seed weight (equivalent to 3.52 tons/ha) which was statistically similar to the interaction of Grobogan varieties and arbuscular mycorrhizal fungi (equivalent to 3.45 tons/ha). In terms of economics of resources, the use of arbuscular mycorrhizal fungi is not required to be combined with phosphate solubilizing fungi.

Abstract

[VEGETATIVE AND REPRODUCTIVE PERFORMANCES OF MAIZE HYBRIDS GENERATED FROM INBRED MUTANTS (M4) ON DARMAGA LATOSOL]. The development of hybrids from local germplasms are extensively done as alternative to the expensive imported hybrid seeds. The farthest genetic distance of parental lines is required to develop the best hybrids. The objective of this study was to compare the vegetative and reproductive performances of hybrids generated from crosses of M4 inbred lines, generated from the selected gamma irradiated mutants. Twenty eight hybrids derived from diallel crosses of M4 inbred lines and a check hybrid variety (NK33) were evaluated on Darmaga latosol. The results showed that all hybrids had lower performances on vegetative and reproductive characters compared to NK33. However, based on the selection index involving all characters, hybrids of G3 x G8, G6 x G8, and G8 x G6  with the index values of   9.45, 7.85, and 6.72, respectively,  performed better than or similar to  NK33.

Abstract

Peat soil is one of the ecosystem having large potensial to be developed as a productive agricultural land if properly managed. Peat soil has constraints to plant growth such as physical, chemical, and biological properties. The application of mineral soil containing high pyrite content is expected to improve chemical characteristic of peat soil by bonding between cationic iron replenished mineral soil containing pyrite and phenolic acid ligand derived from peat soil. The objective of this experiment was to study the effectiveness of mineral soil containing pyrite incorporated by peat soils to the growth and yield of paddy rice. Experiment was done in a laboratory and green house of the Centre for Soil and Agroclimate Research and Development, Bogor using peat soil and mineral soil containing pyrite taken from Sugihan Kiri, Musi Banyuasin, South Sumatera. There are 13 treatments studied in the experiment, with 3 replications. Result showed that amelioration of peat soil applied by mineral soil with high content of pyrite, it’s potensial to improve the productivity of rice.
