Water lettuce ( Pistia stratiotes ) is one of the important aquatic weeds because it can cause many problems for humans and the environment. In addition, the declining quality and quantity of water is also due to the invasion of water lettuce weeds covering the surface of waters, which can lead to the increasing transpiration and destruction of plankton making the balance of the ecosystem disrupted. This study was conducted in an attempt to control P. Stratiotes by utilizing the biological control agent Spodoptera pectinicornis with mass production and its releasing applications in South Kalimantan’s waters. The study was started by taking and collecting S. pectinicornis from several places/fields. The moths were then placed in trays of water and put in a gauze cage of 75 cm x 75 cm x 75 cm in order to keep the air circulation. They were nourished in the laboratory to produce groups of eggs. The groups of eggs were then transferred to rearing ponds. When a fair number of agents were obtained, the treatment of liquid fertilizer AB Mix was carried out. The results showed that the fertilization treatment to water lettuce weeds as the food for the biological control agent S. pectinicornis did not differ from the condition when there was no fertilization treatment either on the feeding ability, weight of larvae and pupae or fitness of imago. However, its destructive ability is high that it has a big potential as a biological control of water lettuce.

ABSTRACT Talas banana ( Musa paradisiaca var. sapientum L.) has a high economic value. However, because of slowly breeding, a quick way of propagation: i.e. in vitro is required.Peatlands inSouth Kalimantan are quite large and has potential to be used for planting area of Talas banana. The acclimatization of seedlings planted on the peatsrequires more fertilizers, considering the low nutrient content of the peats. This study aims to determine the chicken manure and nitrogen-phosphor-potassium (NPK) fertilizer on the growth of Talasbanana acclimatized in peatlands. This study applied a randomized block design (RBD) factorial: (1) the amount of chicken manure (K), namely: k 1 = 5 t ha -1 ; k 2 = 10 t ha -1 ; k 3 = 15 t ha -1 ; k 4 = 20 t ha -1 , and (2) the amount of NPK fertilizers (P), namely: p 1 = 200 kg ha -1 ; p 2 = 250 kg ha -1 ; p 3 = 300 kg ha -1 . Therefore, 12 treatments. DITAMBAHKAN TERDAPAT 12 PERLAKUAN. All treatments have 3 replicates. The results of the experiment showed that there was no interaction between doses of chicken manure with NPK. The amount of chicken manure 5 t ha -1 resulted in the highest increment of plant height observed at 2 nd , 4 th , 6 th , 8 th , 10 th and 12 th week after planting, increment of stem diameter, addition of leaf number, width and length of leaves.The results of experiment also revealed that the best increment of plant height observed at 8 th week after planting and stem diameter observed at 4 th week after planting was obtained by 250 kg ha -1 of NPK fertilizer application.

Several experiments have been carried out to elucidate the reduction in greenhouse gas emissions as effect of replacement of chemical fertilizer by biofertilizers on alluvial soils in Indonesia. Biofertilizers “Biotara” and “Biosure” were applied along with NPK fertilizer on alluvial soil cultivated with rice. Emissions of nitrous oxide (N 2 O), methane (CH 4 ) and carbon dioxide (CO 2 ) were monitored in biweekly basis up to the maximum vegetative growth of the rice plant. Oil palm empty fruit bunch (OP EFB) as well as grasses were composted with Bacillus brevis and Bacillus megaterium as activator. The composts were incorporated into alluvial soils cultivated to oil palm and the emissions of N 2 O, CH 4 and CO 2 were monitored in biweekly basis. The results showed that biofertilizer “Biotara” or “Biosure” combined with NPK fertilizer (¾ recommendation dose) could increase paddy growth with no significant effect on N 2 O, CH 4 and CO 2 emissions. The emissions of N 2 O, CH 4 and CO 2 exhibited seasonal changes as affected by inclusion of either OP EFB and weed compost along with NPK fertilizer. Global warming potentials of each treatment for NPK, OP EFB compost and weed compost were 5.6, -5.2 and -4.9 ton CO 2 equ m - 2 year -1 , respectively. It could be concluded that the replacements of synthetic fertilizer with biofertilizer or compost did not have negative impact on the environment which could be promoted.

Rudrasagar lake, a Ramsar site in India offers a variety of ecosystem services. The contribution of Rudrasagar lake to the society has not been estimated so far. The preliminary study aims to provide an economic valuation of the provisional and cultural services of the Rudrasagar lake. Official records of revenue collected by the Tourism Department of Tripura and a socio- economic survey was the source of information used in the economic valuation of the lake. The main provisional services provided by the lake are food (aquatic plants and fishes), fuel wood and timber whereas, the cultural services provided were boat raiding and tourism due to its historical importance. The provisioning and cultural services provided by the Rudrasagar lake are 40810 US$ and 33929.33 US$ per year respectively during the period of 2010-2015. The main threats to the wetland identified are increasing silt loads due to deforestation, expansion of agricultural land and land conversion due to population pressure. To alleviate the anthropogenic stress on the lake, better monitoring, planning and management are essential. By proper conservation and management it will be possible to enjoy the provisional and cultural services of the lake in a sustainable way.

Abstract: Barind tract of west Bengal is an uplifted old alluvial plain area where only <1 percent area is covered by wetland. Present paper concentrates on general understanding of wetland association with different geographical settings like geological, geomorphological lithological structure and altitudinal gradations. Detail investigation reveals that geological and morphological structure do not have deep influence on wetland formation and their distribution in particular favourable sub-region. But altitudinal control on wetland is noticeable. An irregular distribution of wetland is found throughout the region because of multi parametric influence on it. In recent decades wetlands in barind tract has been undergoing into rapid loss. Continuous encroachment of agricultural field and newly built-up area to wetland are considered as main causes of wetland loss in barind tract.

Peat land accumulates organic materials and emits greenhouse gas (GHG). Agricultural activities in peat land cause the subsidence of peat land surface and the loss of carbon in the form of GHG. Appropriate management of peat land for agriculture would reduce GHG emission. This research aims to understand the microorganism population dynamics and emission of GHG on the treatment of chicken manure application in peat land. The research was conducted in the GHG Laboratory of Indonesia Agricultural Environment Research Institute (IAERI) in 2012 using peat material taken from Jabiren, Central Kalimantan. The experiment was done by incubating peat soil for 2 months with the treatment of chicken manure application and without manure. The incubation experiment was conducted by using paralon PVC pipe. Parameters observed included pH, Eh, bacteria population and fungi, as well as GHG flux (CO 2 , CH 4 and N 2 O). GHG samples taking method was used a sealed containment. The research result showed at the peat given chicken manure treatment, bacteria population decreased at the end of incubation; fungi population, however, increased. The application of chicken manure on peat land planted rubber trees and pineapples would reduce GHG emission by 12.8% as compared without manure application.

The application of chicken manure on peat land planted rubber trees and pineapples would reduce GHG emission by 12.8% as compared without manure application.","PeriodicalId":30661,"journal":{"name":"Journal of Wetlands Environmental Management","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83601773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
ABSTRACT Shallot cultivation in peat land was constrained by the high production costs, especially fertilizer and lime costs (Abdullah, 2011). Therefore, improvement of shallot productivity in peat land was to use local resources so that the production costs would be reduced. Potential material to be used for that purpose was sea mud which abundantly available in West Kalimantan. The productivity of several shallot varieties in peat land had not reached their production potential. The research used Randomized Block Design (RBD) with the treatment of sea mud consisted of without the treatment of sea mud (L 0 ) and with the treatment of sea mud (L 1 ) and several shallot varieties such as Bima Variety (V1), Manjung Variety (V2) and Sumenep Variety (V3). The research result showed that the treatment of sea mud and varieties of shallot differed significantly in improving the growth and production of shallot. Bima, Manjung and Sumenep each produced 14.73 ton/ha, 12.84 ton/ha and 9.22 ton/ha respectively. Based on profit value and B/C ratio value, the utilization of sea mud in peat land was economically feasible to be applied by farmers in West Kalimantan.
