Economic Appraisal of Farm Pond Investments and Their Impact on Wheat and Barley Cultivation in Jaipur District of Rajasthan, India | Chapter 8 | Agricultural Sciences: Techniques and Innovations Vol. 6

 

Farm ponds play a pivotal role in optimising land and water resources for agricultural purposes, considering both surface water and groundwater. They serve as critical assets in the efficient management and conservation of soil and water resources, offering multifaceted solutions to meet diverse agricultural needs. This study aimed to assess the economic feasibility of investing in farm ponds among farmers in Jaipur district, Rajasthan, India. Primary data for this study were taken from eighty farmers, including 40 beneficiaries of RKVY-PDMC and MKSY and 40 non-beneficiary farmers for the agricultural year 2021-22. The study's findings revealed the cost of cultivation analysis for wheat and barley. In the case of the wheat crop, farm pond farmers recorded higher yields and profitability, with net returns increasing by 37.19 per cent, returns over variable costs by 34.25 per cent, and the cost of production declining by 28.34 per cent relative to non-farm pond farmers. A similar pattern was observed in the barley crop, where net returns rose by 43.33 per cent, returns over variable costs improved by 37.73 per cent, and the cost of production decreased by 22.07 per cent under farm pond conditions. Across both crops, assured and timely irrigation from farm ponds contributed to reduced expenditure on key variable inputs, particularly irrigation, fertilisers, and plant protection chemicals-thereby enhancing input-use efficiency, stabilising yields, and significantly improving overall economic performance. The total costs for constructing plastic-lined farm ponds were ₹242,348.56 without subsidy and ₹137,348.56 with subsidy per pond. Cost component-wise, machinery, labour, and material costs accounted for the majority (95%) of the total establishment cost without subsidy. The economic evaluation indicators demonstrated favourable outcomes for farm pond investments. The net present worth of the investment was positive, the benefit-cost ratio exceeded one and was positive, the internal rate of return exceeded the prevailing interest rate, and the payback period was relatively short, both with and without subsidies. This suggests that the government should continue to increase subsidy support for plastic-lined farm pond construction to promote economic prosperity among farmers.

Economic Evaluation of Passive Solar Distillation System: A Recent Study | Chapter 9 | Technological Innovation in Engineering Research Vol. 5

An economic study of a passive solar distillation unit is presented in this chapter. The startup and ongoing costs, system life, and estimated costs per unit mass of distilled water were used to evaluate the net present worth (NPW), benefit-cost ratio, payback period (PP), and internal rate of return (IRR) of a solar distillation unit. One simple and affordable low-carbon method is solar distillation. According to calculations, the Net Present Value (NPW), Benefit-Cost Ratio (BCRR), Payback Period (PP), and Internal Rate of Return (IRR) are each Rs. 26945.72, 1.5632, 1.538 years, and 50%, respectively. This study demonstrated that one of the most alluring sources of energy for distilling water is solar energy.

How to Select and Design an Appropriate Mining Method: A Case Example of Baluba East Upper T-Block, Zambia| Chapter 6 | Recent Trends in Chemical and Material Sciences Vol.6

World over, in the history of mining, various mining method selection techniques such as qualitative and multi-criteria decisions approaches have been applied to choose an appropriate mining method. However, to date no single mining method selection technique has been universally adopted due to the variations and number of factors involved in the selection process which are usually mine site specific. In this study, we applied the University of British Columbia (UBC) technique for selecting and ranking the mining methods using Baluba Mine in Zambia as a case study. All the top three mining methods were designed using AutoCAD and the most appropriate method was selected based on preliminary economic evaluation of development costs. The selected mining method was further subjected to economic evaluation based on the amount of extracted ore and waste using the Net Present Value (NPV) and Payback Period to establish its viability.

Economic Evaluation of Weed Control and Herbicide Residues on Cassava (Manihot esculenta Crantz) in Ghana: Advanced Study | Chapter 3 | Research and Development in Agricultural Sciences Vol. 3

 

A study on economic evaluation of some weed management strategies and herbicide residues
analysis on roots of cassava (Manihot esculenta Crantz) was conducted during 2014 and 2015
cropping season in Kumasi, Ghana. Cost and benefits were computed from the use of two manual
weedings (hoeing and cutlassing), two pre-emergence herbicides (Butachlor 60% EC and Terbulor
500 EC) with two-supplementary hoe weeding, weed-free and weedy check. These were evaluated
using two varieties of cassava, Ampong (Early branching) and Dokuduade (Late branching). The
treatment was a factorial laid out in a randomized complete block design (RCBD) with four replicates.
Partial farm budgeting were used for economic analysis of data and herbicide residues analysis in
roots of cassava were determined using Gas Chromatography-Electron Capture Detector (GC-ECD).
Results showed that Terbulor 500 EC with two supplementary hoe weeding was more economical,
profitable and beneficial than those other treatments applied in the production of cassava. In addition,
the average concentration of Terbulor 500 EC (0.003 mg/kg) and Butachlor 60% EC (0.001 mg/kg)
residues in roots of cassava varieties were below the maximum residue limit (MRL) of 0.01 mg/kg set
by Ghana Standards Authority for cassava. In conclusion, Terbulor 500 EC with two supplementary
hoe weeding was more effective and financially rewarding and both herbicides had lower residual
effects on cassava.|
