A study on the economic analysis of fish production using different feed types practiced in Dhanusha district was conducted in 2018. Out of 600 fish farmers, sixty fish farmers(10%) from the Fish Superzone region i.e. Janakpur sub-metropolitan city, Bideh municipality, Sahidnagar municipality, Kamala municipality, Hanspur municipality, Janaknandani rural municipality and Aaurahi  rural municipality, selected using simple random sampling, were surveyed using semi-structured questionnaire. The study revealed that locally formulated mash feed was commonly used feed type in which rice bran and mustard oil cake (RB+MOC) was the principle feed ingredient. 55% of the farmers used rice bran and mustard oil cake (RB+MOC), 20% used rice bran, mustard oil cake and soybean (RB+MOC+SOB), 10% used rice bran, mustard oil cake and fish meal (RB+MOC+FM) and 15% farmers mineral and vitamin (RB+MOC+MIN/VIT) in their feed formulation. The productivity of the fish production in feed type RB+MOC+SOB (3.41±1.02) was significantly higher than other feed type.  The total variable cost per ha (5.23±2.11) was found significantly(p<0.05) higher in feed type RB+MOC+SOB. Similarly, gross margin (4.44±2.74) received by farmers of feed type RB+MOC+SOB was also significantly high(p<0.05). The Benefit: Cost (B:C) ratio of the study area was found to be 1.69, high being of feed type RB+MOC+SOB(1.84) compared to others. The feed type RB+MOC+SOB is seen as a economically profitable one in the study area because of the high productivity, profit and B:C ratio. High feed cost was the major problem followed by the unavailability of feed. Fish farming can be a profitable business in Dhanusha with large opportunity to increase the fish production with increasing protein sources in the feed used. Farmers should be provided sufficient information, trainings and be encouraged to incorporate the protein rich sources like soybean and fish meal in the feed prepared to increase the productivity and ultimately return.

A field trial was conducted to examine effects of substrates on yield of carp and SIS at Sukranagar Village, Chitwan district for 210 days in farmer’s pond. The experiment was designed with four treatments: T1 (carp only), T2 (carp+SIS), T3 (carp+substrate) and T4 (carp+SIS+substrate) with four replicates. Ponds were stocked with fingerlings of six carp species at a rate of 20,000 fish/ha and two Small indigenous fish species at a rate of 50,000 fish/ha in 1:1 ratio. Prior to stocking of fish, split bamboo mats were fixed in substrate ponds covering 2% of pond surface area to enhance periphyton growth. Carp were fed with dough of rice bran and mustard oil cake (1:1) at the rate of 3% BW daily while Grass carp was fed with grass and banana leaves at 50% BW. Growth and yield of Rohu and Common carp, combined net fish yield and gross margin were found higher (p<0.05) in carp ponds with substrate.

Investigation was carried out from June to August 2009. A total of 40 fish farmers were selected from northwest two upazila namely Debigonj (n=20) and Boda (n=20) where both men and women were targeted. Focus group discussion (FGD) and cross-check interview were conducted to get an overview on carp farming. From 1991-1995, 1996-2000 and after 2000; 17.5%, 45% and 37.5% of fish farmers started carp farming respectively. Average 77.5% of farmers acquired training from NFEP project while 10% of them from government officials. There were 55% seasonal and 45% perennial ponds with average pond size 0.09 ha. After phase out of NFEP project, 92.5% of fish farmers followed polyculture systems, while only 7.5% of them followed monoculture ones. Farmers did not use any lime, organic and inorganic fertilizers in their ponds before association with NFEP project. They used lime, cow dung, urea and T.S.P during pond preparation at the rate of 247, 2562.68, 46.36 and 27.29 kg.ha-1.y-1 respectively where stocking density at the rate of 10,775 fry.ha-1 after phase out of the project. Feeding was at the rate of 3-5% body weight.fish-1.day-1. Rice bran, wheat bran and mustard oil cake used at the rate of 1920, 220 and 110 kg.ha-1.y-1 respectively by 85% of fish farmers but 15% of them did not used any feed. Before NFEP project, average pond production was 408.55 kg.ha-1 but after phase out the project, fish production was 2,861.08 kg.ha-1. Peak culture and harvesting period lied from April to December and from November to January. Average 92.5% of farmers improved their livelihood through carp farming. Fish farming was affected due to low water depth and drought conditions. Keywords: NFEP; Fish farming parameters; Pond production; Livelihood approach DOI: 10.3329/jbau.v8i2.7942 J. Bangladesh Agril.

Increase in soil degradation has negatively impacted on food production. This therefore necessitates sound land management practices. This study analyzed the economics of the land management practices among crop farmers in Osun State, Nigeria. Data were collected with the aid of structured interview schedule from 80 respondents in four Local Government Areas of the state using a three-stage sampling techniques. Budgetary and multiple regression analyses were the analytical tools employed. About 63% of the farmers were male and 78.4% of them were above 38 years. Seventy-two percent of the farmers had secondary sources of income. The average gross margin of the farms was N48,456.56k. The total value product increases by a value of N4.90K for every N1 increase in the total variable cost. The study concludes that land management practices such as fertilizer application, length of fallow on land and length of tillage on land have a positive effect on crop output in the study area. Therefore, extension services should be intensified to disseminate modern ideas and technology in crop farming for greater productivity. Activities that promote soil tillage for crop production should be encouraged as this would increase crop output. Keywords: Economic analysis, Land management, Fallowing, Crop output

A field trial was carried out to test performance of four locally available substrates (split bamboo, whole bamboo, banana midrib and plastic bottle) for periphyton enhancement in farmer's ponds at Seri and Nandapur in Nawalparasi district for 7 months. Six carp species were stocked at 15000 fish/hectare and SIS at unrecorded densities. Carp was fed with rice bran and mustard oil cake at 1.5% BW while grass carp was fed with grass and banana leaves at 50% BW. There was no significant effect of substrates on growth and production of carp. Combined NFY was 19% higher in plastic bottle ponds than control ponds, while NFY of SIS was 50% higher in banana midrib ponds than control and other substrate ponds. FCR was significantly better (P<0.05) in split bamboo ponds than control ponds. Banana midrib decayed fast and was replaced 3-4 times during experimental period while plastic bottles performed better in terms of production and profit.

In order to assess the effect of adding Dedhuwa (Esomus danricus), Mara (Amblyparyngodon mola) and Pothi (Puntius sophore) on Carp production, an experiment was carried out in farmers’ pond in Chitwan. The experiment included four treatments in triplicates: T1, (Carp: Silver carp, Hypophthalmychthys molitrix, Bighead carp, Aristichthys nobilis, Rohu, Labeo rohita and Mrigal, Cirrhinus mrigala), T2 (Carp+Dedhuwa), T3 (Carp+Mara), and T4 (Carp+Pothi). Fish were fed on dough of rice bran and mustard oil cake (1:1) at the rate of 3% of body weight. Results showed that Dedhuwa, Mara and Pothi did not differ significantly (P>0.05) in terms of production. Production of Silver carp and Bighead carp was found significantly higher (P<0.05) in T3 and T4 than control indicating no niche overlapping among these fish. Based on total production and profit T4 appeared to be best.DOI: http://dx.doi.org/10.3126/on.v9i1.5741

A model of sugarcane digestion was applied to indicate the suitability of various locally available supplements for enhancing milk production of Indian crossbred dairy cattle. Milk production was calculated according to simulated energy, lipogenic, glucogenic and aminogenic substrate availability. The model identified the most limiting substrate for milk production from different sugarcane-based diets. For sugarcane tops/urea fed alone, milk production was most limited by amino acid followed by long chain fatty acid availability. Among the protein-rich oil cake supplements at 100, 200 and 300 g supplement/kg total DM, cottonseed oil cake proved superior with a milk yield of 5·5, 7·3 and 8·3 kg/day, respectively. This was followed by mustard oil cake with 5·1, 6·5 and 7·6 kg/day, respectively. In the case of a protein-rich supplement (fish meal), milk yield was limited to 6·6 kg/day due to a shortage of long chain fatty acids. However, at 300 g of supplementation, energy became limiting, with a milk yield of 6·7 kg/day. Supplementation with rice bran and rice polishings at 100, 200 and 300 g restricted milk yield to 4·3, 4·9 and 5·5 and 4·5, 5·3 and 6·1 kg/day, respectively, and amino acids became the factor limiting milk production. The diet comprising basal sugarcane tops supplemented by leguminous fodder, dry fodder (e.g. rice or wheat straw) and concentrates at levels of 100, 200 and 300 g supplements/kg total diet DM proved to be the most balanced with a milk yield of 5·1, 6·7 and 9·0 kg/day, respectively.

The efficacy of seed treatment and foliar spray with fungicides in controlling black point incidence of wheat seeds was evaluated in the field. Two seed treating fungicides, namely Vitavax-200 and Homai-80WP were used @ 0.25% of dry seed weight and foliar spray with Tilt-250EC (0.05%) was applied in six different schedules. Untreated and unsprayed controls were also maintained. Seed treatment with either Vitavax-200 or Homai-80WP significantly increased plant population and grain yield, but none of them was found effective in reducing black point incidence. On the other hand, foliar sprays with Tilt-250EC under all the spray schedules except spraying at 70 and 90 DAS significantly minimized the disease severity over unsprayed control. Among the different spray schedules, spraying at 30, 40, 50, 60, 70, 80, and 90 DAS appeared to be most effective, which was similar to spraying at 30, 45, 60, 75, and 90 DAS in reducing black point incidence and increasing grain yield. Economic analysis on yield advantage showed that the highest additional gross margin of Tk. 6120/ha with BCR 2.57 was obtained from five sprays applied at 30, 45, 60, 75, and 90 DAS.
