Abstract

Corn is an important food crop in Indonesia. Plant expansion has been hampered by soilacidity problem and the protein content of many corn varieties was low. This research initiates development of soil-acid-tolerant corn with highquality- protein content. Research was done on 12 factorial treatments and 3 replications as blocks in RCBD. The first factor was corn populations: Toray-1(G1), Toray-2(G2), GS- 5(G3) and GS-10(G4). The second factor was fertilizations: P1(69 kg N+36 kg P2O5+15 kg K2O per ha)); P2(115 kg N+54 kg P2O5+30 kg K2O per ha); and P3(161 kg N+72 kg P2O5+45 kg K2O per ha). The observed variables consisted of several agronomic traits, including the protein content. Results indicated that the corn populations, in general, showed good agronomic traits. The differences were mostly between populations, not between fertilizations, and no interaction was observed. The yield potential ranged from 4.25 to 6.47 ton dry seeds per ha. The protein content of seed resulted from cross ranged from 9.84% to 11.30%, as compared to the parents of 9.11% and 12.62%. This research concludes that genetic factors play an important role as confirmed by heritability estimate (h2)=0.75.Keywords : Corn, protein, acid-soil, tolerance

Abstract

Sea level rise is a growing threat for the coastal regions of Bangladesh. It is one of the most densely populated countries of the world where 28% of the population are living in the coastal area. Bangladesh has already been affected by sea level rise through land erosion, salinity intrusion and loss in biodiversity. Saline soil has a detrimental effect upon soil physical and chemical properties. The dominant soil textural classes that occur in the saline areas of these regions are silty clay. In both of the soils pH value of the surface horizon is slightly lower than those of the subsoil and sub stratums. Cation Exchange Capacity (CEC) of all these soils varies from 12.0 to 27.6 meq/100 g soil expressing medium to high status. The organic matter content is medium to high at Asasuni and pretty low at Kalapara. In both areas, nutrient deficiencies of total nitrogen, phosphorous and potassium were quite dominant but sulphur was high. Exchangeable sodium, potassium, calcium and magnesium were in high level. The dominant water soluble cations were Na+, Ca2+, Mg2+ and K+ and anions Cl- and SO4 2-.The amount of accumulated salt was found higher at the surface and decreases with depth. Keywords : sea level rise, coastal areas, salinity, soils, flood plain

Abstract

Weeds in the rice fields impact the population of M. vittaticollis and several predators on rice habitat. A study was conducted during rainy season 2004-2005 and dry season 2005, which selective weeding and weed strips were applied. In selective weeding, Monochoria vaginalis, Fimbristylis miliacea, Cyperus iria, and Limnocharis flava were left, and made a weed strip at the periphery of rice plot which was consisted of those four species. Clean weeding as farmers usually do was also applied as a control treatment. Results showed that the presence of weed plant species in the earlier planting season of dry season 2005 tended to maintain the population of the predatory insects of rice pests, in particularly M. vittaticollis and Anaxipha longipennis. Population of Ophionea nigrofasciata, Paederus spp. and Micraspis inops were not different among the treatment plots during rainy season (2004-2005) and dry season (2005). The species number of predator and parasitoids seemed to increase slower in the clean weeded plot in comparing with the species number in selectively weeded or weeds strip’s plot at early planting season. Rice yield in the experimental plots were not significantly different. Some weeds in the rice fields may not have adverse effects on rice productivity.

Abstract

The research was aimed to determine the type, the distribution and the incidence of banana leaf diseases in several production centers in West Sumatra, Bengkulu, North Sumatra and West Java. Direct observations on banana orchards were conducted in some districts in Simalungun, Deli Serdang and Medan (North Sumatra), Tanah Datar, Limapuluh Kota, Agam, Pariaman and Pasaman (West Sumatra), Rejang Lebong and Kepahyang (Bengkulu), Sukabumi, Purwakarta and Subang (West Java) from November to December 2006. Two banana orchards were randomly selected in each district. Plant population at the selected orchard was at least 100 plants. From each sampled orchard, if banana population consisted of similar or only one variety, 10 plants were randomly chosen according to wind direction. Meanwhile, when the banana varieties were varied, five plants were randomly selected. The result showed that Black Sigatoka and Eumusae leaf spot were found in West Sumatra, Bengkulu and North Sumatra at severity level of between 15 % to 62.31%, whilst speckle disease was mainly found in North Sumatra and in parts of West Sumatra at severity level of between 72,72% to 100% and 15 to 30%, respectively. Banana varieties that were primarily attacked by leaf diseases were Cavendish, Telor, Barangan and Emas.Keywords : bananas, black sigatoka, Eumusae, speckle, disease incidence and distribution

Abstract

The greatest problem of modern agricultural practices is the use of chemical pesticides and fertilizers. It is noted that about 40% of the world's land surface is used for agriculture. The way this agricultural land is managed has a great influence on the global environment. Integrated Pest Management (IPM) farming system produces fewer negative externally affects, can effectively restore ecosystems and deliver well ecosystem services. Depending on methods applied and degree of production, agricultural practices impact biodiversity in the ecosystem and it also influences conservation practices within the ecosystem. The result showed that diversity of soil fungi on IPM was higher than diversity on conventional one. Trichoderma sp. and Acremonium sp. which are known as antagonist fungi were found on IPM but not on conventional one. Domination Index on IPM was lower than conventional field. Bacterial leaf blight (Xanthomonas oryzae) disease intensity showed no difference on both systems. The yield on IPM was higher (6.34 ton/ha) than conventional field (5.56 ton/ha). It has been found that rich biodiversity in agricultural environment improves productivity of agricultural systems. The IPM system gives more regard to the soil fungi biodiversity and considers it as an integrated system upon which the success of the agricultural production depends.Keywords : Integrated Pest Management, biodiversity, soil fungi, modern agricultural

Abstract

The experiment was to determine the relationship between yield and yield contributing traits and select the promising genotypes. Twenty two genotypes and two check varieties were evaluated at Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during Rabi season, 2008-2009 in a RCBD with three replications. Significant variation among the lentil genotypes were observed in respect of days to first flowering, days to maturity, plant height, pod/plant, 100-seed weight and yield. The genotype BLX-02009-06-3 flowered and matured earlier. Among the test entries, BLX- 02009-18-3 and BLX-02009-18-1 were tall. The highest number of pod per plant was obtained in BLX-02009-04-5. The large seed size was found in LR9-130 and LR9-25. The highest yield was found in BLX-02009-04-1 followed by BLX- 02009-04-5 than the two check varieties. Difference between genotypic coefficient of variation and phenotypic coefficient of variation was small for the traits as plant height, days to maturity, days to first flowering and 100-seed weight. Among different traits, grain yield had high variation both at genotypic and phenotypic level due to the differences of genetic materials and also the differences of the environment. Grain yield was found to be positively and significantly correlated with plant height, pods/plant, 100-seed weight at genotypic and phenotypic levels.Keywords : Lentil, genetic diversity and PCA

Abstract

The research was aimed to obtain the optimum concentration of BAP to buds growth as in vitro. It was conducted in the Tissue Culture Laboratory at Forestry and gardening seedling Unit of Forestry and Gardening Office of Banten Province from April until December 2008. The research used Randomized Completely Design on MS base medium with different BAP concentration: (1) B1 = MS + Kinetin 0.1 ppm + BAP 1 ppm, (2), B2 = MS + Kinetin 0,1 ppm + BAP 2 ppm, (3) B3 = MS + Kinetin 0,1 ppm + BAP 3 ppm, (4) B4 = MS + Kinetin 0,1 ppm + BAP 4 ppm, (5) B5 = MS + Kinetin 0,1 ppm + BAP 5 ppm. Each treatment was replicated ten times. The data was analyzed and continued with Duncan Multiple Range Test (DMRT) 5 percent. The explant which grew in MS media with different BAP concentration showed radicle appearance. It tended to grow to be embryo, where it began with radicle length and was followed by bud formation. Higher BAP application for each treatment increased the germination. The best concentration of embryo germination which would be grown to be bud was 4 or 5 ppm BAP.

Abstract

The adaptation trial was applied to determine the benefits of genotype-environmental interaction, adaptability and stability of lines. The previous research successfully obtained 8 UB lines which had high yield and tolerant to aphids. These lines belong to plant breeding laboratory of Brawijaya University, which had stability and a high potential can be immediately released to the public. Research was conducted in 2010, dry and rainy season, on 3 locations of yardlong bean, namely Malang, Kediri and Jombang. Randomized Block Design was applied in these locations.Genotype-environment interaction was analyzed with combined analysis of nested design.The adaptability and stability were known from regression analysis based on the stability of Eberhart and Russel. There were 6 stabile lines, namely UB7070P1, UB24089X1, UB606572, UB61318, UB7023J44, and UB715, respectively. They were recommended to be released as new varieties which had pest tolerance and high yield. The UBPU was suitable to be developed in marginal land. The 6 new varieties had registered to Agriculture Department Republic of Indonesia, namely, Brawijaya 1, Brawijaya 3, Brawijaya 4, Bagong 2, Bagong 3 dan Bagong Ungu, respectively.
