Nutrient management, water quality protection, and irrigation efficiency top the list of on-farm resource concerns indicating a need to address them through conservation strategies. A suite of Best Management Practices (BMPs) has been identified and recommended, through several outlets, to farmers to ameliorate these concerns. This research examines the adoption of strategies that ameliorate the resource concerns as a joint decision, using a bivariate model. data from the 2016 Nutrient Management Survey, conducted by the Louisiana Master Farmer Program, are used to examine the factors affecting adoption of these conservation practices. A bivariate probit regression found significant results for explanatory variables and emphasize the effect of perception regarding the role of on-farm practices, ownership of land, participation in conservation programs in the past, and producers educational attainment on the like-lihood of adopting the conservation practices. Implications for policy development and educational programs are discussed.

The aim of the present work is to evaluate proton exchange membrane(PEM) fuel cell performance with a modified serpentine flow field with right angle turn by numerical modeling. A 3-d PEM fuel cell model of size 50 cm^(2) active area is developed. A conventional serpentine flow field is modified and the same is considered for the supply of reactants. Computational fluid dynamics(CFd) based simulations were conducted to analyse the pressure drop, distribution of reactants(H_(2) and O_(2)), liquid water activity, current flux density and water content in the membrane. From the simulation results, polarization curve is drawn to validate the literature data of PEMFC with the conventional serpentine flow field. Comparison of simulated polarization curve with literature data revealed that modified serpentine flow field performance is better than conventional serpentine flow field as it offers better water exclusion and uniform sharing of reactants. From this study, it is concluded that model of flow field pattern influences the functioning of fuel cell and utmost care must take while selecting a pattern for flow field of PEM fuel cell.
