Abstract Soil spatial variability is a primary contributor to within-field yield variation across farms. Spatio-temporal stability and can be assessed through multi-year monitor data geostatistical techniques. Our objective was delineate zones using coupled with gross margins plan precision conservation prescriptions. This study employed corn measurements from 2018, 2019, 2020 farm economics co...

PURPOSE To determine whether tissue visible light spectroscopy (VLS) used during radiofrequency (RF) ablation of liver tumors could aid in detecting when tissue becomes adequately ablated, locate grossly ablated regions long after temperature and hydration measures would no longer be reliable, and differentiate tumor from normal hepatic tissue based on VLS spectral characteristics. MATERIALS ...

this study considered the production economics of coffee in pakuwa village development committee of parbat district, nepal. household survey was done in june 2014. data collection was done using semi-structured pre-tested questionnaire administered on 40 coffee producers selected randomly. gross margin analysis, profitability index and the benefit-cost ratio was used to analyze the production e...

Inventory turnover varies widely across retailers and over time. This variation undermines the usefulness of inventory turnover in performance analysis, benchmarking and working capital management. We develop an empirical model using financial data for 311 public-listed retail firms for the years 1987-2000 to investigate the correlation of inventory turnover with gross margin, capital intensity...

The performance parameters, energetic characteristics and cost factors of direct drilling were evaluated by longterm trials carried out in Osztopán and Gödöllő regions. The effect of direct drilling, disking, ploughing, and soil loosening combined with disking and ploughing on the soil conditions, yields and cost factors was evaluated and based on the examination results. The economic compariso...

Traditional smallholder farming systems are characterized by low yields and high risks of crop failure and food insecurity. Through a biophysical model, PARCHED-THIRST and a socio-economic farming systems simulation model, OLYMPE, we evaluated the performance of farming practices based on maize yield, gross margin and total family balance over a 10-year period in semi-arid Olifants River Basin ...

This paper presents an application of a two and three stages difference in differences model to measure environmental and economic impacts of Farmer Field School on crop and pest management practices of rice in Thailand. Panel data from 241 farm households were collected three times over a period of four years in five rice-producing provinces of Thailand. Data included socio-economic data descr...

The present study was conducted to investigate the impact of breeding season on the productivity and profitability of Barki flock. Simulation technique was used based on technical coefficients derived from statistical analysis of the basic data. Basic data utilized in this study were obtained from the accumulated records collected over 34 successive breeding seasons from 1972 to 2005 of Barki s...

Real options analysis (ROA) is widely recognized as a superior method for valuing projects with managerial flexibilities. Yet, its adoption remains limited due to varied difficulties in its implementation. In this work, we propose a real options approach that utilizes managerial cashflow estimates to value early stage project investments. Our model is based on the assumption that managers can p...

The present study was designed to assess the comparative profitability of four winter vegetables namely cauliflower, cabbage, tomato and brinjal in five villages under Keranigonj Thana of Dhaka district. Four dominant winter vegetables in the study were considered. A simple purposive sampling technique was applied. Five villages were purposively selected for the collection of data. In all, 120 ...
