Abstract

Efforts to improve soybean productivity in tidal land, including through land improvement (amelioration) as of lime, use of improved varieties and the fulfillment of plant nutrients. This study aims to determine the adaptation of some soybean varieties for high yield in the tidal land. Research activities conducted in tidal land Banyu Urip Village Subdistrict Tanjung Lago Banyuasin District from July to September 2013 design used is Split Split Plot Design consisting of 3 factors with 3 replications. Main plots were dose Dolomite (D0= 0 ton/ha dolomite, D1= 2 ton/ha dolomite), subplots were dose of urea (P1= 25 kg/ha urea, P2= 50 kg/ha urea, P2= 75 kg/ha urea) and the plot is children soybean varieties (V1= Argomulyo, V2= Anjasmoro, V3= Tanggamus). Variables measured were plant height 17 DAT, plant height 7 MST, leaf chlorophyll and number of branches. The results showed that the varieties that produce Argomulyo plant height, leaf chlorophyll content, and the number of branches is better than the soybean crop varieties Tanggamus and Anjosmoro. Thus soybean varieties are more adaptive Argomulyo planted in tidal land.

Abstract

The research was conducted in the village of Banyu Urip at Banyuasin district from March to June 2013. This study aimed to examine the effect of organic manure of fermented cow urine (liquid organic fertilizer/ POC) and combined with different doses of inorganic fertilizer on the growth and yield of corn land in the tidal area overflow type C. This study uses a randomized block design consisting of 5 treatment was repeated 5 times. Each treatment unit with a plot size of 1.5 m x 10 m. Treatment in this study are as follows: J0 = 100% recommended dose of inorganic fertilizer without POC cow urine; J1 = 75% recommended dose of inorganic fertilizer + POC cow urine; J2 = 50% recommended dose of inorganic fertilizer + POC cow urine; J3 = 25% recommended dose of inorganic fertilizer + POC cow urine, and J4 = 100 % POC cow urine without inorganic fertilizers. The results of fertilizer application treatments using organic and inorganic fertilizers on maize showed significant effect on all observed variables. Further test results show that the inorganic fertilizer treatment J2 = 50% of the recommended dose of cow urine + POC gives the highest yield for plant height (162.22 cm), number of leaves, corn with cornhusk weight (187.70 g), the weight of the corn without cornhusk (177.54 g), dry shelled weight (139.05 g), weight of 100 grains (30.87 g) and the number of seed rows per ear (16.60), as well as significantly different to the other treatments.

Abstract

Banyuasin district is one of the rice producing regions in South Sumatra which rely on sub-optimal land type with category tidal land to produce rice production. The statistical data showed that Banyuasin District is a region that produces the highest rice production of rice-producing areas in South Sumatra. However, the high level of production is not able to guarantee farmers' income is also high, and prices at the consumer level will be low. This is because rice prices received by farmers is still relatively quite low. The condition is the main attraction of researchers to conduct this research with the aim to analyze the pattern of marketing tidal swamp rice production through the analysis of marketing channels, marketing margins, marketing efficiency level and method of pricing of each institution tidal swamp rice marketing in the District Banyuasin This study was conducted in District Rambutan Banyuasin Regency, with time data collection in April-May 2014. The results showed that there are two groups of marketing channels tidal swamp rice production in the district which are both classified as Banyuasin indirect marketing channels. Pricing method of rice is determined by the merchant so that farmers are recipients of the price (price taker) while marketing agency is a price maker. The calculation of the value of marketing margins in both marketing channel marketing agency in each figure shows the range varies with Rp.400 per kg to Rp, 3,100, - per kg. The analysis shows that the pattern of marketing efficiency marketing tidal swamp rice production is already relatively efficient, with the highest levels of efficiency are the major traders.

Abstract

The research has been conducted at rainfield lowland of non tidal swamp in Kecamatan Rambutan Kabupaten Banyuasin in March to May 2014. Objection of research was to find the treatment for seed of rice before planting with application of Zn and nitrogen fertilizer. This factorial experiment was set by randomized block design with three replications. First factor was 6 rice varieties, second factor is two levels of Zn treatment (0 mM and 5,0 mM), and third factor is two level of N fertilizer (30 and 60 kg/ha). The 15-day seedlings, were submerged for 5 days. The parameters, dry weight of seedling, carbohydrate of stem, and chlorophyll of leaf, were measured on 10 days after submergence treatment. Carbohydrate and chlorophyll was measured according to the methode of Yoshida et al. (1976). Result of research showed that application of Zn and N increased dry weight, carbohydrate, and chlorophyll of seedling. Therefore rice seedling will be more tolerant in submergence stress.

Abstract

Manure enriched by rock phosphate (RP) and inoculated with biodecomposer very important to improve the upland fertility. Residual effects of applied manure can be used for the next growing season. The objective of the research was to investigate the residual effects of some kind of manure on sweet corn (Zea mays saccharata), dry matter (DM) and P production of stover on second growing season. A field experiment of completely randomized design with 7 treatments and four replicates. Level of P (RP), N (urea) and K (KCl) fertilizers was 66 kg P/ha, 200 kg N/ha, and 125 kg K/ha, respectively. All of manure application at 30 ton/ha and enriched with RP. The treatments at the first growing season were T0 (manure), T1 (manure +EM4), T2 (manure+starTmik), T3 (manure +stardec), T4 (manure granular+EM4), T5 (manure granular+starTmik), and T6 (manure granular+stardec). The sweet corn was harvested at 70 days, the stover was cut and measured for DM and P production. The result showed that effect of some kind of manure was not significantly different to sweet corn and DM production. Manure inoculated with biodecomposer resulted in signficantly higher of P production than without biodecomposer. Conclusion, all of manure resulted in similar on sweet corn and DM, except manure inoculated with biodecomposer resulted in higher of P production than without biodecomposer.

Abstract

Swamp land in Lampung area of 544,305 ha, which spread out in several districts, where a potential for planting rice paddy field area of 410,177 ha. The pattern cultivation especially fertilization also different from each other in each type of land swamp and a specific location, so have an effect on yield. This study had done by the method survey and interviews farmers by using a questioner. Location interview was in three districts that have land swamp area in Lampung, namely Tulang Bawang District (Sub District: Rawa Jitu Selatan, Rawa Pitu, and Penawar Aji); Mesuji District (Sub District: Mesuji Timur and Mesuji); and Lampung Selatan District (Sub District: Rawa Sragi). The number of respondents 15 farmers per sub-district, so the total respondents were 90 farmers. The data were obtained then tabulated and analyzed descriptively. Most of the farmers used these wetlands for rice farming, but only 50% can be used for double cropping of rice per year. The dose of fertilizer farmers applied both urea and NPK Ponska / SP-36 lower than recommended dosage according to Permentan Regulation No. 40 of 2007 (Urea 175 kg + 200 kg Ponska NPK + 25 kg SP-36 + 50 kg KCl). Average rice yield was obtained according to the results of interviews 4.34 t/ha in MT I and 2.5 t/ha in MT II.

Abstract

The objective of this study is to examine the morphological characteristics of the superior soybean varieties against sucking pod pests in drought stress conditions. The investigations have been carried out in June-August 2012 in the greenhouse of the Faculty of Agriculture, University of Mataram. Experiments have been designed by using completely randomized design with treatment consist of eight soybean varieties namely Anjasmoro, Panderman, Burangrang, Lawit, Argomulyo, Kaba, Tanggamus and Grobogan, with 3 replications. The parameters measured were: 1) Tickeness of pods skin, 2) trichome pods length; 3) trichome density of pods, 4) the attacks intensity; 6) plant resistance. Data analysis of the studies were performed using ANOVA on the significance level of 5 percent. The results showed that seven varieties of soybeas tested were tended to have the same length of pod trichome, and they did not have any strong correlation with attack intensity of pod sucking insect pest. In addition, the thickness of pod skin had a strong correlation with attack intensity, the ticker of pod skin, the lower of attack intensity. On the other hand, the density of pod trichome did not have any strong influence on attack intensity of pod sucking pest of soybean

Abstract

There are uncountable research activities and technology development efforts have been carried out in Indonesia; however, very limited economically and/or socially beneficial technologies have been created. Very few indigenous technologies have been used in producing goods and providing services, including in agricultural sector. This problem is rooted on facts that most of the technologies developed are not relevant to real needs and/or problems of domestic farmers. Even if the technologies are substantially relevant; in many cases, they are not finacially affordable by domestic farmers, do not significantly increase profit if used, and/or less competitive compared to similar available technologies in the market. Limited availability of resources, at present and even more scarse in the future, elevates expectation on technology to contribute in establishing inclusive, productive, and sustainable agricultural development. To assure that developed technology will be relevant to the needs and contribute to agricultural development, farmers ought to be play significant active roles during priority setting, planning, and developing the technology. The real issues at present are increase in food demand as consequence of population growth and conversion of arable lands for uses in other sectors. These trends have led to intensifying agricultural activities on suboptimal lands. Efforts to increase agricultural productivity in suboptimal lands should not jeopardize sustainable function of the ecosystem and participation of local farmers. Sustainability and inclusivity should be maintained while increasing productivity. Traditional knowledge and local wisdom have to be treated as reference for developing technology for establishing productive agriculture on suboptimal lands.

Abstract

Mining activities provide economic benefits and also cause environmental and land ecosystems damages. The damage caused by such top soil layer loss, drought, soil compaction, low water holding capacity, poor nutrient (macro nutrients), accumulation of toxic elements and highly acidic soil reaction. Mined land reclamation of coal with bio-fertilizer technology as arbuscular mycorrhizal fungi (AMF) indigenous is one of the technologies for revegetation of land with environmentally friendly systems. This study aims to get a AMF biofertilizers indigenous effective and adaptive for rubber seedlings planted in coal-mined soil. Research used a completely randomized design with one factor that the FMA indigenous derived from in coal-mined soil; A (without inoculation; B (inoculation of Glomus sp-5), C (inoculation of Glomus sp-6), D (inoculation of Glomus sp-7), E (inoculation of Glomus sp-12), F (inoculation of Glomus sp-15); G (inoculation Acaulospora sp-1), H (inoculation Acaulospora sp-2), I (inoculation Acaulospora sp-3), J (inoculation Acaulospora sp-4), K (a combination of all-Glomus sp), L (a combination of all Acaulospora sp), M (combined all-Glomus sp-sp and Acaulospora). Data were analyzed with a 5% level of variance followed by DMRT 5% level. parameters measured were AMF colonization, seedling height, dry weight, available P, pH and Al. Research results can be concluded that the inoculation of all AMF Glomus sp and Acaulospora sp gave the highest colonization 53.33%, increased soil pH 15%, decreased the Al 56% and increased the available P of 9.25%.

Abstract

Annisa, et al. Technologies for Mitigating Greenhouse Gas Emissions on Tidal Swamp Land. JLSO 5(2):178-188.Utilization of swamps for agricultural development is a strategic choice in an effort to offset the decrease in productive land in Java due to conversion of land functions from agriculture to non-agriculture. The properties of land in swamplands is a major limiting factor that causes low productivity of swamp land. The development of agriculture in swamplands often has a negative impact on land and environment, due to inappropriate landl management. One of the environmental impacts in swampland development is carbon emissions. Carbon emissions can be reduced through the use of appropriate soil ameliorant and water management within the swamp hydrological area. Both approaches are important not only to mitigate greenhouse gas emissions but also to increase swampland agriculture productivity.
