Profitability Efficiency Analysis of Methyl Bromide Fumigants and Mulch Systems Alternatives for Pepper Production in Georgia AgEcon
Ferrer, Myra Clarisse R.; Fonsah, Esendugue Greg; Escalante, Cesar L.; Culpepper, Stanley.
With the goal of looking for the best fumigant substitute not only effective to production yield but more importantly to profitability and its excellent corresponding mulching option, this study used the complete factorial treatment analysis approach. Seven fumigant options and four mulching alternatives were included in the study and results showed that 1,3-dichloropropene plus chloropicrin and metam sodium (TELPICVAP) and smooth low density black on black polyethylene mulch (METAL) are the most profitable fumigant and mulch option.

Soil Water Potentials and Capsicum annuum L. under Salinity Rev. Bras. Ciênc. Solo
and,Heitor Henrique Félix Duarte; Souza,Edivan Rodrigues de.
ABSTRACT Investigations into water potentials in the soil-plant system are of great relevance in environments with abiotic stresses, such as salinity and drought. An experiment was developed using bell pepper in a Neossolo Flúvico (Fluvent) irrigated with water of six levels of electrical conductivity (0, 1, 3, 5, 7 and 9 dS m-1) by using exclusively NaCl and by simulating the actual condition (using a mixture of salts). The treatments were arranged in a randomized block design, in a 6 × 2 factorial arrangement, with four replicates. Soil matric (Ψm) and osmotic (Ψo) potentials were determined 70 days after transplanting (DAT). Soil total potential was considered as the sum of Ψm and Ψo. Leaf water (obtained with the Scholander Chamber) and osmotic...
