The occurrence of soil loss is a continuous process and occurs spatially across the earth’s surface. The study of soil loss is a necessity for proper understanding of the processes and the rate of soil loss for conservational purpose. Landsat Thematic Mapper (TM)/Enhanced Thematic Mapper Plus (ETM+)/Operational Land Imager (OLI) image data was acquired for 1986, 2003 and 2020 were used to derive the C factor of the RUSLE model while other factors of the model were kept fixed for the years considering their inability to change easily. The RUSLE model was used to determine the trend of the soil loss on the alluvium geologic formation considering their land use/land cover changes for 1986, 2003 and 2020. The rainfall erosivity of the study area had an average of 8201.45MJmmha-1h-1yr-1. The soil erodibility index of the soils obtained from Alluvium had an average of 0.150tons MJ-1 hmm-1. The slope length and steepness factor of the study area range from 0 to 2.574. the crop cover factor of for 1986 range from 0.52 to 0.87, 2003 range from 0.52 to 0.87 and 2020 range from 0.62 to 0.92. No active field conservation was found out within the study area as described by Wischmeier and Smith. The results obtained show that 1986, 2003 and 2020 had a soil loss of 1966.3, 2167.85 and 3361.14 tonha-1yr-1 respectively. The results show that the study area is experiencing an increased trend of soil loss. This result can serve as guide into understanding the past and current rate of soil loss for soil resource planning and management

Sorghum (red and white) were germinated for 24, 48, 72, and 96 h to determine the effect of germination on some functional and engineering properties of sorghum flour. The bulk density results for the red and white germinated sorghum are 0.620-0.673 g/cm3 and 0.477-0.620 g/cm3, respectively. Water absorption capacity values for the two samples are 116.630-125.970% and 81.643-98.293% while the oil absorption capacity ranged from 62.917 to 85.750% and 44.933 to 61.980%, respectively for the two samples. The dispersibility test for the two samples gave 85.67-87.33% and 83.00-84.67%. The swelling power at 55 °C are 2.54-2.67 and 2.70-3.26, at 75 °C, 3.62-4.68 and 3.85-4.56, and at 90 °C, 2.98-4.79 and 6.29-7.23, respectively for the two samples. For the engineering properties, the specific heat capacity ranged from 0.14 to 0.45 kJ/kg K and 0.12 to 0.14 kJ/kg K, thermal conductivity, from 0.55 to 1.67 W/mK and 1.01 to 1.24 W/mK and thermal diffusivity from 0.13 to 0.82 m2/s and 0.11 to 0.12 m2/s, respectively for red and white germinated sorghum flours. It can be concluded from this study that increased the values of bulk density, WAC, OAC, and dispersibility test of the two samples with the increase in germination period with the optimum germination period of 72 h. Engineering properties results indicated that germination had a beneficial effect on the thermal conductivity of the germinated red sorghum and the thermal conductivity and specific heat capacity of the white germinated sorghum with 96 h having the best result for both samples.

The study on Multi-layer budding of oversized rubber seedling aimed at evaluating the success of multiple budding operation on single seedling of rubber tree species comprising of 4 to 7 budding layers per seedling. The experiment used randomized complete blocked design layout with 3 treatments such as 4, 5 and 7 layer budding in a single seedling replicated 4 times. Results revealed that the highest number of budding layers succeeded significantly higher as compared to 4 and 5 layers. The main survival percentage is about 79.17% for the 7 layers, 76.52% for the 5 layers and only about 55.36% for the 4 layers. Pure garden soil reported to have significant results on sprouting rate, sprout length, stalk diameter and number of leaves. This finding emphasized that budding of rejected oversized rubber seedlings grown in an abandoned nurseries can be reutilized for mass production of budded cuttings through multiple budding of 7 layers per seedlings to maximize planting materials derived from single seedlings.

The experiment was conducted at the farmer’s fields of three Charlands in Bangladesh during November 2019 to July 2020 for establishing new technologies for enhancement of productivity through innovative soil management practices. The experiments were established in a randomized complete block design using six treatments and three replications. Treatments of the experiments were T1 = FP (Farmers’ Practice) (Control), T2 = RF (Recommended Fertilizer) + Vermicompost (3t/ha), T3 = RF (Recommended Fertilizer) + Quick Compost (3t/ha), T4 = RF (Recommended Fertilizer) + Standard Organic Fertilizers (3t/ha), T5 = RF (Recommended Fertilizer) + Poultry Manure (3t/ha) and T6 = RF (Recommended Fertilizer) + Biochar (3t/ha). The soil status in all selected Charlands were very low to optimum. Results of the experiment showed that application of organic fertilizers along with inorganic fertilizers produced significant (p<0.05) variation in growth and yield parameters of the crops. The findings from the study showed that different organic fertilizers showed better performance compared to Farmer’s practice. The statistically maximum fruit yield (41.35t/ha) of pumpkin, grain yield (3.24t/ha) of millet and tuber yield (43.69t/ha) of sweet potato was recorded in biochar treated T6 treatment compared to other treatments. Besides, the statistically highest fresh fruit yield (29.50t/ha) of snake gourd, fresh fruit yield (20.80t/ha) of okra and yield (74.16t/ha) of Indian spinach were recorded in poultry manure treated T5 treatment compared to other treatments. Comparatively higher growth and yield of different crops were obtained from poultry manure along with inorganic fertilizers which was followed by biochar and quick compost application. It is recommended to the farmers to use organic fertilizers along with inorganic fertilizers.

The objective of this paper is to determine the factors that favour the granting of credit in the microfinance institution at the Local Bank of Mutual Agricultural Credit (LBMAC) the largest in BENIN in a rural area. In methodological terms, the estimation of a logistic regression model has been made. Several variables are collected to explain access to agricultural credit in the institution. The results of the estimates show that, having one person as a guarantor and the seniority in obtaining the loan influence the granting of credit. As a result, the LBMAC is very selective, greatly limiting the demand for credit from farmers. So, economic policies must offer favourable conditions for micro-finance in the agricultural sector to increase their numbers and also allow them to be less selective.
