Potassium (K) and phosphorus (P) application to sunflower (Helianthus annus L.) reduced cost of production, increased seed oil and protein concentration, yield and net returns on the K and P deficient soils in Northwest Pakistan. Field experiment was conducted at the New Developmental Research...

We use the concept of the product space to analyze the key features of the transformation process in Africa with a focus on the agricultural sector. Between 1962 and 2008, we find that both specialization and diversification occur for the overall economy and across sectors. Our findings also...

Recent trend depicts that tomatoes and tomatoes products rank 2nd most important vegetable crop in the United States after potatoes and potatoes products contributing 20 percent of total vegetable production. More-so, tomato is equally ranked 2nd in the United States in terms of production...

The parameters of yield response functions can vary by year. Past studies usually assume yield functions are nonstochastic or ‘limited’ stochastic. In this study, we estimate rye-ryegrass yield functions where all parameters are random. Optimal nitrogen rates are calculated for two yield...

Perennial crop production is inherently dynamic due to several salient physical characteristics including an establishment period of several years with low or no yields, long lives in commercial production (40 years or more), and path-dependence of yields on input use and other exogenous...

The U.S. government recruits immigrant workers through the H-2A program as a short-term solution to the agricultural sectors’ labor shortage problem. Although the sector insists hiring immigrant workers is essential for their survival, history has proven the socio-economic cost for doing so is...

This study uses an agricultural household model to examine the tradeoff between farm profitability and a household head’s desire for market work. The theoretical analysis is a comparative statics analysis relative to the two variables. Results show that the tradeoff can arise for...

The potential of agricultural biotechnology to produce seed traits that reduce yield risk generates widespread excitement. Hopes are high that in an era of tightening water constraints and climate change drought tolerant (DT) crop varieties will stabilize food production and allow for greater...
