Performance Analysis of Sweet Pepper (Capsicum annuum L.) under Varied Farming Managements in Marginal Uplands |Chapter 6 | Agricultural Sciences: Techniques and Innovations Vol. 4

 

This study investigates the performance of sweet pepper (Capsicum annuum L.) under different farming management practices in marginal uplands. The results revealed that microbial-enriched organic fertiliser did not match the efficacy of inorganic fertilisers in enhancing sweet pepper yield and yield components. Specifically, Inorganic fertilizer significantly improved sweet pepper yield at 6,880.74 kg ha-1 (P<0.01). Additionally, cost and return analysis revealed that goat manure yielded the highest Return on Investment (ROI) at 860.79, followed closely by goat manure + IMO 3 with an ROI of 774.18. These findings provide valuable insights for optimizing farming practices to enhance sweet pepper production in marginal uplands while considering economic viability.

Experimental Study of White Layer Thickness and Hardness Reduction in EDM Using Flux Powder | Chapter 11 | Technological Innovation in Engineering Research Vol. 2

 Electrical Discharge Machining (EDM) is a very important machining method in the mould production industry. However, there is always a disserved white layer on the cut surface. To make it simpler to remove, the white coating has been thinned or softened in various ways. PM-EDM (Powder Mix EDM) is a method in which powder is mixed with a dielectric fluid. In this study, powder fluxes from welding electrodes with a range of organic and inorganic components were employed. A normal blender is then used to smash the flux flakes. The powder can be refined again and again until it achieves the appropriate grain diameter. By sieving with a 400 mesh filter, the powder is picked with a maximum diameter of 40 m. This filter will produce a powder with a diameter of 37 microns. The flux powder was then combined with kerosene dielectric fluid at concentrations of 0 g/l, 2 g/l, 4 g/l, 6 g/l, 8 g/l, 10 g/l, and 20 g/l. Furthermore, all machining parameters are kept constant with the anticipation that flux concentration will be the sole factor affecting the cutting outcome. The application of flux concentrations ranging from 2% to 8% resulted in a 42 percent reduction in the thickness of the white layer.
