Research interests:  Development of sustainable organic production systems for vegetable, field and medicinal crops: Evaluation and development of production practices for introduction and establishment of new crops in a given environment; Agroforestry-forest farming with forest medicinal species; alley cropping with vegetable and medicinal herbs; Evaluation of genotypes using growth, radiation use efficiency, and yield component analyses.

Detailed Research Expertise:

Current research on medicinal plants with hypoglycemic/antihyperglycemic properties involves evaluation of germplasm lines, development of chemical profiles, and validation of their medicinal properties, primarily antidiabetic properties through collaborative research with other institutions. Develop best management practices for cover crop-based sustainable organic production systems for vegetable, field, and medicinal crops.  Evaluation and introduction of new crops in a given environment, evaluation of inputs and technologies for improving soil and crop productivity. Establishment of pigeonpea (Cajanus cajan) as a food and feed crop in Alabama. Providing guidance and help limited resource farmers in the black belt counties of Alabama achieve self sufficiency in sustainable organic production systems. 


Evaluation of genotypes using growth, radiation use efficiency, and yield component analyses. Screening germplasm and identification of physiological requirements for adaptation of crops to new environments. Working with breeders towards development of  improved cultivars with greater productivity. Conducting research to identify and develop environmentally friendly, sustainable crop production/management practices for improved crop productivity and profits to farmers.  Has several years of field and greenhouse research experience in agronomy and physiology of a variety of field/row and vegetable crops in diverse environments. 

Current Agronomic Research

Expertise and facilities for conducting cutting-edge agronomic/horticultural research on field, vegetable, and medicinal crops.

Sustainable Organic Production Systems:  Development of cover crop-based organic production systems for vegetable and medicinal crops.

Production and Demonstration of Ethnic Vegetable Crops.  Popular Hispanic, Indian, Chinese/Japanese/Korean vegetable crops in North Alabama.

Medicinal Plants Research:

Development of sustainable organic production systems for medicinal crops, basil, turmeric, and bitter melon.  Potential crops:  Aloe and Ashwagandha.

Validation of medicinal properties, identification of mode of action, identification, isolation, and characterization of bioactive compounds through collaborative research with other institutions.

Research on service berry (Amelanchier alnifolia):  Determination of mode of action of Antidiabetic activity and isolation and identification of bioactive compounds.

Research on Basil: 

Production practices- both conventional and organic systems.

Genotypic variation in growth and elemental chemical profiles of basil (Ocimum tenuiflorum) with and without nutrient stress.

Response of basil (Ocimum tenuiflorum) to four soil types of Alabama.

New crops for Alabama:

Pigeonpea (Cajanus cajan) as a potential vegetable and forage crop for small farms in Alabama.

Establishment of mungbean (Vigna radiata) as a cash crop in Alabama.


Crop Improvement in collaboration with West Virginia State University:

Determination of phenotypic and genotypic relationships in water melon, development of linkage map, and identification of QTLs associated with desirable fruit traits.
