A Density-Ratio Model of Crop Yield Distributions
This paper proposes a density ratio estimator of crop yield distributions, wherein the number of observations for individual distributions is often quite small. The density ratio approach models individual densities as distortions from a common baseline density. We introduce a probability integral transformation to the density ratio method that simplifies the modeling of distortion functions. W...
متن کاملEconomies of Density versus Natural Advantage: Crop Choice on the Back Forty
We estimate the factors determining specialization of crop choice at the level of individual fields, distinguishing between the role of natural advantage (soil characteristics) and economies of density (scale economies achieved when farmers plant neighboring fields with the same crop). Using rich geographic data from North Dakota, including new data on crop choice collected by satellite, we est...
متن کاملCrop Yield and Plant Density under Diff erent Tillage Systems
To determine the optimal ploughing depth and to make tillage simpler and less costly, but also taking account of edaphic and climatic conditions as well as biological and agrotechnical requirements of crops grown, long-term investigations (1994-2009) have been carried out on Stagnic Luvisol of sloping terrains in central Croatia near Daruvar. Th e paper presents the results relating to plant de...
متن کاملEffect of plant density and different irrigation strategieson crop yield and canopy cover of red beans, Phaseolusvulgaris L. cv. Akhtar
ABSTRACT- In order to study the effects of different irrigation regimes and plant density on yield and yield components of bean, a split plot arrangement was conducted in complete randomized block design during two years. The foremost variable was four levels of irrigation: 60, 80, 100, and 120% of the potential evapotranspiration. The second variable was within the row spacing of 5 cm (D1), 10...
متن کاملMalaria, Adaptation and Crop Choice
This paper investigates how rural farm households adapt to the risk of disease. In the context of malaria, adaptation brings to mind mosquito nets, sprays and coils. However, adaptation may be more subtle. For instance, households living in malaria-endemic regions may alter their crop choice to reduce their exposure to disease and the associated likelihood of crop failure. Thus the risk of mala...
