Abstract:
The breeding and genetic peculiarities for kernel weight per plant in spring barley varieties of different origin (Ukraine, Western European countries, and Canada), purposes of usage (forage, malting, food) and botanical varieties (covered and naked, awned and awnless) under conditions of Ukrainian Forest-Steppe were revealed. In the diallel crossing scheme with only elite malting barley varieties accordance with the additive-dominant system and overdominance in loci were found. The manifestation of kernel weight per plant was reliably increased by the dominant effects. Accordingly to the indicator of the degree of phenotypic dominance, parameters of genetic variation, graphical regression analysis, effects of GCA and constants of SCA in the hybrid populations will be effective final selection for high kernel weight per plant in later generations, when dominant alleles become homozygous. When different botanical varieties were involved in crosses much more complex gene action for the trait manifestation with strong epistasis and multidirectional dominance were determined. Thus, it is theoretically possible to select plants with high productivity on recessive or dominant basis. The negative aspect is that it will require further extensive evaluation of the splitting generations. Awned spring barley varieties Datcha and MIP Myroslav, as well as awnless variety Kozyr can be used as an effective genetic source for involvement in crossings aimed to improving the kernel weight per plant. Naked spring barley varieties require more breeding improvement in plant productivity compare to covered ones.

Abstract:
The purpose of this study was to examine saltwater recreational anglers’ answers to the fifteen statements regarding the importance of fishing trips, and to classify groups exhibiting common patterns of responses from individuals’ recreational fishing motivations using the data extracted from the database collected from the 2013 National Saltwater Angler Survey. Using the factor analysis, the fifteen statements were reduced into five dimensions, named catch, information, site preferences, social, and management. Empirical results based on the k-means clustering analysis identified three different saltwater recreational angler groups, named catch and social, site choice, and fishing related groups. Results of the discriminant analysis indicated that cluster means were significantly different. The multilayer perceptron neural network model was utilized as a predictive model in deciding the classification of saltwater anglers based on recreational fishing motivations. From an architectural perspective, it showed a 15-9-3 neural network construction. This study may provide insight into the information about what types of saltwater recreational anger groups exist and identifying unknown groups in the data set for saltwater recreational fishing planning and management purposes.

Abstract:
Tea is a major plantation crop and the socioeconomic pillar of Terai region of West Bengal. Use of various inorganic fertilizers may have increased the crop production but affected the environment badly. Importance of biomass of different trees in accumulation of carbon had long been known but few studies on characterization of biomass accumulation are reported. So, selection of different species for getting the good amount of organic nutrients is important. In tea plantation, various leguminous trees are used as shade trees. This research, conducted in the tea plantation of University of North Bengal, has provided some approaches which could possibly reduce the application of inorganic fertilizers. Different tests on physicochemical parameters, micronutrients status, biomass etc. were conducted with the collected plant litters. The results of this comparative analysis suggested and validated the beneficial effects of each shade tree in organically maintaining nutrient profile of tea plantation soil.

Abstract:
This study was conducted to identify the socioeconomic characteristics of Transplant Aman (T. Aman) rice producers, compare the profitability of modern and traditional varieties and, analyze the factors affecting the production of modern and traditional T. Aman rice varieties. The multistage sampling procedure was used for selecting 60 farmers from Muktagacha, Ishworgonj and, Fulbaria Upazila under the Mymensingh district of Bangladesh. A semi-structured interview schedule was used for the purpose of collecting primary data. Tabular analysis, undiscounted BCR and, Cobb-Douglas production model were used for analyzing the data. The major findings of the study were that about 43.34% of the respondents belonged to the age between 46-65 years, 71.67% were male, 41.67% had primary education only, agriculture was the main occupation of 75% of the respondents and 53.33% had access to credit. The per acre average net return was Tk 16760.71 with a BCR of 1.47. The comparative analysis revealed that the per acre average net return and BCR of modern variety of T. Aman were Tk 23737.98 and 1.68 and of traditional variety of T. Aman were Tk 10601.58 and 1.27, respectively. The results of Cobb-Douglas production model showed that human labor cost, Urea cost, Boron cost, seed cost, pesticides cost, threshing and, drying cost had significant effects on the production of the modern variety. The findings of this study suggest that the production of the modern variety of T. Aman will be profitable which in turn will contribute to ensuring food security among the rural poor.

Abstract:
The study investigated the influence of fertilization treatments and tillage on the quality of soybean flour and milk samples. The fertilization treatments were as follows: 10t/h (4.5kg) organic; 5t/ha (2.25kg organic + 50%NPK 15:15:15); 15t/ha (6.75kg organic + 50% NPK 15:15:15); 10t/ha (4.5kg + 50% NPK 15:15:15); 100% NPK 15:15:15 and control (no treatment). These applications were made on tilled and non- tilled soils respectively and cumulated to sample codes T1, T2, T3, T4, T5, T6, NT1, NT2, NT3, NT4, NT5 and NT6. The soybean samples were milled and the samples were subjected to functional and chemical analyses. These samples were used to produce soymilk which was subjected to sensory evaluation. The functional properties results for bulk density, swelling capacity, water absorbing capacity (WAC), foaming capacity and pH ranged from 0.54-0.69%, 87-248%, 0.65-1.45%, 5.45-31.70% and 5.90-6.40 respectively. Proximate composition of the samples ranged from 6.32-11.33% moisture, 26.45-49.65% protein, 15.09 -18.65% fat, 4.69-8.22% ash, 5.05-13.73% crude fibre and19.95-32.40% carbohydrate. The mineral composition ranged from 32.30 – 49.56 mg/100g, 0.05 – 0.07 mg/100g and 0.04 - 0.35 mg/100g for calcium, iron and potassium respectively. The vitamin content ranged from 1.19 – 2.52mg/100g, 0.18-0.39mg/100g, 0.01 - 0.03mg/100g and 9.80-13.41 mg/100 for B1, B2, B12 and B6 respectively. The anti-nutrient result for phytate, trypsin inhibitor and heamaglutinin ranged from 0.11-0.20 mg/100g, 0.05-0.13 mg/100g and 0.56-1.44 Hu/gm respectively. Samples obtained from tilled soil showed best results. Sensory results of the soymilk showed improved attributes when compared to the control samples.

Abstract:
Sweet potato is a food and nutrition security crop in sub-Saharan Africa with low yields resulting from soil infertility. We examined the effects of nine fertilizer regimes on the growth performance of orange-fleshed (OFSP) and white-fleshed (WFSP) sweet potato varieties in two agro-ecological zones characterized by Andosol and Nitisol soils. The treatments were: NPK20-10-10, NPK6-15-28, rice husk biochar (RHB), fast compost (FC), Tithonia diversifolia leaf powder, poultry litter (PL), RHB/NPK20-10-10, FC/NPK20-10-10 and PL/NPK20-10-10. These were compared to a control of no fertilizer. The Andosol and Nitisol soils were acidic with significant differences (p < 0.05) in total nitrogen, organic carbon, C/N ratio, phosphorus, potassium, calcium and magnesium. Fertilizer effects were dominant on the adventitious root, total and marketable yields, moderately affecting main stem length and harvest index (HI) with weak effects on branch number, petiole length and leaf area index (LAI). Soil type and sweet potato variety strongly affected main stem length and HI. Variety × fertilizer strongly influenced adventitious root formation, while soil × variety × fertilizer affected total and marketable yields. LAI, primary branch number, dry biomass, total and marketable yields were best for the OFSP in the Andosol, while main stem length, petiole length, adventitious roots and HI were best for the WFSP in the Nitisol. Results of the study showed that FC, PL/NPK20-10-10 and RHB/NPK20-10-10 were the most promising soil fertility amendments to boost sweet potato productivity in the Nitisols and Andosols.

Abstract:
The main objective of this research article is to analyze the impact of the production of some major crops, namely rice, jute, wheat, sugarcane, and potato on the agriculture sector in Bangladesh. The agriculture sector is considered an important sector of the Bangladeshi economy, which supplies a significant proportion of the gross domestic product (GDP). Annual time-series data for the period 1988–2017 is used for the study. Several econometric techniques are employed to examine the data, including the augmented Dickey-Fuller (ADF) test, Johansen cointegration test, and ordinary least squares (OLS) method. To validate the model, some residual diagnostic tests, namely a normality test, heteroskedasticity test, serial correlation test, and stability diagnostic test are conducted. The findings of the study demonstrate that there are two cointegrating equations in the model. Furthermore, both wheat and jute production have a significant positive impact on the agriculture sector. Although the impacts of rice and potato production on the agriculture sector are positive, these are not significant at the 5 or 10 percent significance level. On the other hand, sugarcane production has a negative and significant impact on the agriculture sector, which was not expected. Based on the results, this paper recommends that the government of Bangladesh should focus on designing and implementing new funding policies and subsidies to improve the growth, production, and development of the sugarcane sector. Finally, the government should be concerned about climate change-related factors that negatively affect crop production in Bangladesh.

Abstract:
The experiment was conducted to evaluate the performance of dhap residue and nutrient sources on the growth and yield of red amaranth, radish and garlic during the period from October, 2013 to February 2014 and October, 2014 to February 2015 at Gopalganj district in Bangladesh. The single factor experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. There were eight treatments viz. control (without organic and inorganic fertilizer), cowdung, recommended dose of NPK, 50% cowdung + 50% recommended dose of NPK, dhap residue, dhap residue + cowdung, dhap residue + recommended dose of NPK, dhap residue +50% cowdung +50% recommended dose of NPK. Dhap residue significantly influences the growth and yield of all three crops i.e red amaranth, radish and garlic. In respect of red amaranth, the tallest plant (43.70 cm and 42.37 cm, respectively) and maximum number of leaves (33.00 and 33.33, respectively) per plant as well as yield (20.88 and 21.32 t ha-1, respectively) were observed from dhap residue + 50% cow dung + 50% recommended dose of NPK which was significantly similar to dhap residue + recommended dose of NPK in both the years. Similar results were also observed in radish for root growth and in bulb production of garlic. From economic consideration, the application of dhap residue + 50% cow dung + 50% recommended dose of NPK fertilizers were suitable for growth and yield as well as cost effective for red amaranth, radish and garlic production under the climatic conditions in Gopalganj district of Bangladesh.

Abstract:
A study was conducted to determine the effects of slope position and fertilizer type on soil properties and growth of maize (Zea mays) on Coastal Plain Sands of Akwa Ibom State, Nigeria. Results obtained showed that soils of lower slope (LS) had the highest contents of clay and silt compared with those of upper slope (US) position. Bulk density of the upper slope soil and that of the middle slope (MS) soils were significantly higher (P≤0.05) than that of LS soil and subsequently, total porosity and saturated hydraulic conductivity (Ksat) increased downslope. Bulk density of soils that received poultry manure (PM) and NPK+PM were significantly reduced compared to those of NPK and control while total porosity and Ksat of soils that received PM and NPK+PM were significantly higher (P≤0.05) than those of NPK and control. Soils of LS had highest pH, organic carbon, total nitrogen, available phosphorus, ECEC compared to those of MS and US. The application of poultry manure yielded increase in soil pH, soil organic carbon, total nitrogen, available phosphorus and ECEC when compared to soils of NPK and control. Growth of maize obtained with LS were consistently higher than those of the MS and US soils. Soils of LS that received NPK and NPK+PM had consistently similar maize growth, higher than other combinations of slope position and fertilizer type. The complementary application of poultry manure and NPK 15:15:15 can be the best option for increasing the fertility of soils with varying slope positions on Coastal Plain Sands.

Abstract:
Association of sustainability agriculture and farming practices is somehow closely connected. There are necessary different farming practices for both adjusted and unadjusted PFSI measurement. The study observes practices of paddy farming and if farmers are practicing agriculture sustainably by estimating PFSI in three villages of Gutudia union. The objective is to spot the present agricultural practices and accessible sustainable practices, to examine the sustainability degree at field beneath the present paddy farming systems using PFSI and additionally to identify recommendations. The unit of analysis is 50 farmers and measured on a scale of 0 to 100 and also through Saltiel, Bauder, and Palakovich (1994) index. The results discovers that the average sustainability level which is presumably quite unsustainable this shows the necessity for more extension of correct practices. Chi-square analysis shows that the level of farmers’ awareness toward sustainable agriculture and positive attitude are considerably different with the level of PFSI.
