A field study was conducted in the ‘haor’ areas of Sunamgonj district, Bangladesh, aimed to investigate the present irrigation practices to identify the related problems for ‘Boro’ rice cultivation. The primary field data were collected by interviewing 120 farmers (landless, small, medium, and large farmers) through survey. Most of the farmers used ‘beel’ (37.5%) as the main source of irrigation water. As water-lifting devices, they mostly used Low Lift Pumps (77.5%). The cost of irrigation was observed the lowest at Derai [Tk. 12,232 ($ 146.784) per season] and the highest was at Dakshin Sunamganj [Tk. 46109 ($ 553.31) per season], respectively. The highest benefit-cost ratio (BCR) was observed at Derai (2.48) and the lowest was at Dowarabazar (2.01). The financial problem, less water supply, lack of irrigation equipment, and knowledge about operating the equipment were identified as the main problems suffered by the farmers. These problems can be solved by distributing irrigation equipments at a reasonable price, and arranging training programs to develop the farmers’ skills.

The study assessed the determinants of coffee production and marketing on farmers’ farms in Kogi State. Two Local Government Areas (Ijumu and Kabba-Bunu Local Government Areas) were purposively sampled. These areas are known for the production and marketing of coffee. A total sample of eighty-four respondents was randomly selected from the two Local Government Areas. Structured interview schedules were used for data collection from respondents. The data collected were analyzed using inferential statistics analysis. Cobb-Douglas functional form regression model was chosen based on the value of the R2 and the number of significant variables. The result indicated that marital status, household size, educational level, variety of coffee planted, farm size and farming experience constituted the major factors that significantly determined coffee production and marketing in the study area. The study recommended that policies should be targeted at encouraging literacy among coffee farmers to have access to market information and as such will be able to sell the crop for more profits. Also, households with higher number of persons should be encouraged to use family labour effectively in coffee marketing than other economic ventures so as to improve the economy of the households in the study area.

A pot experiment was conducted to test the potential of different soil organic ameliorants in salt affected soils reclamation; to test the effect of soil organic ameliorants on the growth and yield of shallot onion (Allium ascalonicum L.) planted in salt affected soil; determine the most effective soil organic ameliorants on salt affected soil Treatments prepared were; T1- Control Salt affected soil (1.57 kg/pot-1), T2- Vermi-cast (197.40 g/pot-1) with CRH (30 grams/pot-1),T3- Guano dung (39.40 g pot-1 with CRH (30 grams/pot-1), T4- Dried Goat Manure (115.40 g/pot-1) with CRH (30 grams/pot-1), T5- Dried Chicken Dung (94.94 g pot-1) with CRH (30 grams/pot-1), T6- Dried Cattle Manure (214.30 g/pot-1) with CRH (30 grams/pot-1). The study was laid out using Randomized complete block design with treatments and three replications. All organic ameliorants applied to the salt affected soil significantly improved on   average bulb diameter, average height, average number of leaves, average bulb fresh weight, average number of tillers and average yield per hectare. It can be concluded that application of organic ameliorants is effective means to address the problem in saline affected soils.

Factors Affecting the Adoption Level of Good Agricultural Practices by Cucurbit Farmers in Anuradhapura District, Sri Lanka

Aims: The primary focus of this empirical study was to investigate the factors influencing the level of GAP adoption for cucurbit vegetable in the Anuradhapura district of Sri Lanka.

Study Design: Three-stage purposive and proportionate sampling 

Place and Duration of Study: The study was carried out in the Anuradhapura district, North Central Province of Sri Lanka in 2018. 

Methodology: Primary and secondary data were used in the study. The primary data were collected mainly through a field survey using a structured and pre-tested questionnaire. The total sample size was 120.  Key informant interviews (KII), and a focus group discussion (FGD) were conducted to triangulate data and information obtained from the questionnaire survey and to obtain additional qualitative information. Descriptive analytical techniques, analysis of variance (ANOVA) test, and the General Linear Model (GLM) were employed for the data analysis.  

Results: Results revealed that 40% of respondents are moderate level GAP adopters, whilst about 68% practiced more than half of the recommended GAPs. The results of ANOVA revealed that farmers who adopted a higher proportion of GAPs earned a higher farming income, than those who practiced a moderate or low proportion of GAPs. Similarly, when compared to moderate and poor level GAP adopters, the average cost of production of higher-level adopters decreased significantly (p < 0.05). The results of the regression analysis revealed that farmer awareness of GAPs, farmer education level, farming experience, farming income, and cost of cultivation have a significant (p < 0.05) effect on the level of GAP adoption by cucurbit farmers.

Conclusion: Awareness of GAPs, farmer education level, farming experience, and farming income significantly affect the adoption level of GAPs. Policy priority should be given to planning for a long-term farmer awareness program on GAPs through proper training and extension programs.

Soil-less system constitutes an efficient approach for the cultivation of tomato; however, organic liquid amendments are very limited under such systems. The current experiment aimed to evaluate the effects of Kurojiru (K), an organic liquid fertilizer and fulvic acid (FA) on the growth and production of tomato, Solanum lycopersicum L. cv. ‘Momotaro’. Recently, it is desirable to reduce the environmental impact and fertilizer cost by lowering the concentration of inorganic components in the culture medium. Therefore, we explored the effect of adding these organic fertilizers on the yield and quality of tomatoes by gradually reducing the phosphoric acid concentration in the culture medium (87, 58 and 29 mmol・pot-1・week-1). The whole experiment was conducted for 20 weeks (from seeding until harvesting). The plant biomass, tomato fruit weight and chlorophyll content were measured. The fresh weight (FW) of both root and shoot indicated a progress response according to phosphorus concentration in liquid media, in FA treatments. Total fresh weight was significantly higher in the treatment with K+FA than in the control. Additionally, the yield responded to the all treatments within the 58 mmol P. Especially, in this level of P the relative fruit weight was higher only under K application. The chlorophyll content responded K+FA treatment under a low P content (29 mmol), and to all of those in 58 mmol. These results indicate that Kurojiru has some positive effects on tomato growth in soil-less systems.
