Therefore, the objective of this study was to investigate effects of filter cake (FC) and bagasse ash (BA) application on soil acidity under greenhouse condition. The experiment was laid out in a completely randomised design with four replications. The FC and BA were investigated separately each with six levels (0, 20, 40, 60, 80, and 100) t/ha -1 . The acidic soil was collected from Imdibir area at a depth of 0-20 cm, air dried, ground and passed through 4 mm sieve. Each pot was received 4 kg of soil with respective treatment material after they were well homogenised. The laboratory analysis revealed that the soil had an initial pH of 5.1, while filter cake and bagasse ash had pH values of 8.0 and 10.2, respectively. Application of FC increased soil pH from 5.1 to 7.3, along with improvements in organic matter, nitrogen, phosphorus, sulphur, potassium, calcium, magnesium, and cation exchange capacity. Similarly, BA application raised pH from 5.1 to 7.4 and enhanced organic matter, nitrogen, phosphorus, sulphur, potassium, calcium, magnesium, and cation exchange capacity. The maximum effects for both FC and BA occurred at the highest application rate (100 t/ha -1 ), while iron and manganese content increased with BA application but decreased as rates increased, and copper and zinc levels were positively affected by both FC and BA applications. Overall, both FC and BA applications significantly improved soil pH and nutrient content. The findings of this study can provide practical and cost-effective solutions for improving soil fertility and crop production

Hence, to avoid soil and water loss, while using the Broad Bed and Furrow (BBF), slope and BBF length have to be considered. Field experiments were conducted on Vertisols having different slopes (1,2 and 3%) and BBF lengths (10,20 and 30m) using split-plot design. Slope gradients and BBF lengths were the main and sub-plot treatments, respectively. Results revealed the main and interaction effect of BBF lengths and slope gradients were significant on all parameters, except for tiller's number. Higher grain yield (5757kg ha-1), was obtained from plots of 10 m BBF length for 2% slope, while higher grain yield of 2148 and 3318kg ha-1 recorded from 20m of BBF for both 1% and 3% slopes, respectively. However, slope gradient and BBF lengths did not brought a significant effect on soil erosion and deposition. This could be due the slopes selected are under the same slope category. Therefore, further study is needed to estimate effects of BBF lengths and slopes on soil loss and crop yield using lands having large slope gradient or categories.

Filter cake application was found to better increase in nitrogen (N), sodium (Na), calcium (Ca), potassium (K), and magnesium (Mg) uptake and utilization efficiency while bagasse ash influenced zinc (Zn) and copper (Cu) uptake. Bagasse ash application also reduced the uptake of iron (Fe) and manganese (Mn) by wheat. Multiple regression analysis showed that the soil properties explained selected macronutrients and micronutrients uptake. Exchangeable acidity negatively explained some of the nutrient uptakes. In general, filter cake and bagasse ash were found effective in enhancing the nutrient uptake and utilization efficiency by wheat cultivated in acidic soils such as nitisol.

Methods Six levels of filter cake and bagasse ash each separately and control check were arranged in a completely randomized design with three replications. Results At 100 tons/ha, both inputs resulted in the highest values of all the investigated traits. It was also found that yield and yield components that were obtained from bagasse ash overwhelmed those from filter cake treatments, except in tillers, dry biomass, and straw yield. Linear regression analysis revealed a significant and positive relationship between grain yield with that of total N, P, K, S, Ca, Mg, Cu, and Zn uptake. A linear relationship between the grain yield with that of N and Zn uptake was found, while the association between grain yield with total P, K, S, Ca, Mg and Cu uptake was quadratic. Conclusion It can be concluded that filter cake and bagasse ash are good sources of nutrients to enhance wheat yield in acidic soil. To give a conclusive result, these inputs should be tested in field trials in different soil types.
