EFFECTS OF HIGH AND LOW MANAGEMENT INTENSITY ON PROFITABILITY FOR THREE WATERMELON GENOTYPES AgEcon
Taylor, Merritt J.; Lu, Wenhua; Duthie, James A; Roberts, B. Warren; Edelson, Jonathan V..
A replicated, small plot study on watermelon [Citrullus lanatus (Thunberg) Matsumura and Nakai] in 1997, 1999, and 2000 revealed that production management intensity affected yields and profitability of watermelon, in Oklahoma. Management intensity was based on a combination of cultural practices and levels of use of production methods. Low intensity management (LM) consisted of use of soil fertilization and weed control. High intensity management (HM) included the same weed control and fertilization as LM but also included use of plastic mulch, drip irrigation, insect pest control, and plant disease control. Cost and return analyses were based on the range of actual prices during the cropping season and the range of yields during the three years....

Organic and Conventional Vegetable Production in Oklahoma AgEcon
Khanal, Kalpana; Henneberry, Shida Rastegari; Taylor, Merritt J.; Schatzer, Raymond Joe; Epplin, Francis M.; Roberts, B. Warren; Edelson, Jonathan V.; Shrefler, Jim.
This study compares he profitability and risk related to conventional and organic vegetable production systems A linear programming model was used to find the optimal mix of vegetables in both production systems. And a target MOTAD (minimization of total absolute deviation) model was used to perform risk analysis in both organic and conventional production systems
