Research History and Record

Conducted research that resulted in: 1) formulating and guiding the development of management strategies for the Early Soybean Production System (ESPS), which is a new and now dominant production concept in the midsouthern USA that was developed to avoid drought stress; 2) formulating and developing management systems that include crop rotation, soybean maturity group, stale seedbed technology, and tillage and weed control inputs to determine the most economical combinations for use in dryland and irrigated ESPS and conventional systems; 3) developing cost effective, water-conserving strategies for irrigation management in ESPS and conventional production systems in the southern US; and 4) identifying morphological traits for use in developing breeding strategies for earliness and canopy development. Personal expertise in agronomy, soil science, production economics, and soil-water-plant principles.

Personally formulated, initiated, coordinated, executed, and documented significant research to provide answers and solutions to production problems in the midsouthern USA. Carried out a unified program of field studies to specifically determine: 1) effects of soil water (or its lack) on soybean growth and development; 2) factors such as tillage, rotation, irrigation, weed management, and planting environment and time that can be manipulated and/or modified to optimize yield and reduce costs; 3) effect of soil and aboveground environment on growth and development of soybean and dominant pests; and 4) planting systems, irrigation management schemes, cropping schemes, and their interactions that can stabilize planting dates, yield, and economic return. Complex methods and concepts were required to complete the integrated research assignment, which was carried out individually and cooperatively with others at the location and across the region.

Developed the "Stale Seedbed Planting System" (conducting necessary seedbed preparation tillage in the fall, killing winter/spring weeds with a preplant, foliar-applied herbicide) for clay soils. The acceptance of this concept is documented by more than 18 known citations in popular press publications, and the decision by Monsanto Agricultural Co. to package and market Roundup D-Pak specifically for use in stale seedbed plantings. Ten invitations to speak about this concept and the above-mentioned popular press citations attest to individual's authority on the subject. Designed and oversaw construction of innovative equipment for pesticide application to randomized plots, and a bedder implement that can accomodate varying row spacings used in early soybean plantings on clay soil. Broad-based and in-depth irrigation research established individual as the authority in soybean irrigation management for midsouthern soybean. The value, significance, and importance of total irrigation research program and its authoritative findings are verified by 37 popular press articles citing the work, and 29 invitations to speak on the subject. Introduced the combination of the Stale Seedbed Planting System and the Early Soybean Production System (ESPS) for clay soils in the midsouthern USA, and conducted the first research using the combination of these concepts. Changed the paradigm for soybean production in the midsouthern US by evolving the Early Soybean Production System. This new concept was developed for drought avoidance, and requires using the stale seedbed planting system and seeding early-maturing cultivars in late March/April vs. traditional May and June seeding of later-maturing cultivars into a spring-tilled seedbed. Overcame resistance to this new concept by advising and working directly with producers who made large-scale ESPS plantings, by conducting economic analyses to show consistently greater profits, and by transferring this new technology through popular press articles and oral and electronic media presentations. The ESPS concept has now been adopted on several million acres in the region. The importance of this research and the resulting concept, and the individual's authoritative part in it, are verified by over 25 popular press articles citing the ESPS work, and 14 invitations to speak on the subject.

Major Accomplishments

Is a recognized authority in the fields of irrigation management, stale seedbed technology, cropping systems, and the ESPS (Early Soybean Production System). Was involved in independent and team research with ARS for over 29 years. Sole or senior author of 47 refereed journal papers, 12 technical research reports (experiment station and USDA publications), 17 invited proceedings papers, and 6 invited book chapters; junior author of 20 journal papers, 12 technical research reports, 2 invited proceedings papers, and 2 invited book chapters; senior editor of one book and one handbook; has presented papers at regional, national, and international professional meetings. 70+ invitations to present research findings at industry meetings, university seminars, research conferences, and radio and television farm programs attest to authority in areas of expertise.

Accomplishment: Documented the effect of two commonly occurring, widespread, and dissimilar soil types (loamy and clayey) common to the lower Mississippi River alluvial plain on emergence, vegetative growth, and development of soybean. Impact: Used in relating management decisions regarding soybean production to a knowledge of soil types and their inherent properties, and how these properties affect growth, development, and final seed yield of soybean in sometimes different fashion. Results of this work are used as a guide in field irrigation research, and are being used by plant breeders in the development of new breeding lines which have particular adaptability to one or the other but not necessarily both soil types.

Accomplishment: Established the importance of irrigation as an integral management component for soybeans grown on the millions of acres of clay soil in the midsouthern USA. Results of integrated studies demonstrated: 1) irrigation initiated before beginning bloom of monocropped soybean provides no significant yield advantage above that realized from irrigation applied only during reproductive development; 2) irrigation should be initiated at or near bloom in a dry year, and at any period of drought stress during reproductive development in a wet year; 3) regardless of planting date, row spacing was not as important a management consideration as was the alleviation of drought stress; 4) without irrigation, planting soybeans during the heretofore recommended optimum planting time provided no significant yield advantage over later-than-normal plantings; and 5) the flood duration period that is inherent in flood irrigation of soybean on the flat alluvial soils in the region should not exceed 48 hours for maximum yield increases from irrigation to be attained. Impact: Results from initial research have provided impetus for the application of proper irrigation management to about 33% of the soybean acreage in the region (3+ million acres) for a potential increase in income of over $360,000,000 per year (3 million acres x 20 bu/acre increase x $6/bu.).

Accomplishment: Demonstrated in extensive field experiments that the stale seedbed approach is the best management practice for planting soybeans on clay soils. Limited tillage that may be required between harvest and planting can be performed in the fall, late winter, or early spring with equal effect. Pre- and post-plant weeds can be controlled effectively with combinations of preplant foliar-applied and pre- and postemergence herbicides. Use of this minimum tillage concept virtually guarantees earlier planting, which results in higher yields and greater profits. Impact: This technology has been applied to millions of acres planted to all crops in the region, and the economic consequences (over $50,000,000 potential increase in yearly income for soybean) of this work are far-reaching.

Accomplishment: Established that soybean grown on clay soil should be irrigated during the full reproductive period and that surface irrigation could be terminated at about mid-seedfill for maximum yield and profit. This was the first economic analysis of soybean irrigation responses that was applicable to the millions of irrigated acres in the humid, subtropical, midsouthern USA, and it provides significant impetus for managing irrigation to increase economic return. Also established that irrigation should be used in seed production environments to ensure maximum germinability of seed in addition to maximum yield. Impact: These findings result in the savings of that amount of money ( $4/acre) and water ( 3 in./acre) that is associated with the one additional watering that was previously applied at the full seed or later stages of soybean grown on the approximately 3 million irrigated acres in the region. This information is being used by seed producers to obtain maximum yield of high-quality planting seed. Also, seed producers will realize maximum profit since irrigation will assure that the most seed of the highest quality will be produced for sale as higher-priced seed beans.

Accomplishment: Incumbent and co-workers demonstrated that soybean rotated with corn and sorghum on clay soil produced more seed yield and net returns than when grown in monoculture in nonirrigated and irrigated environments. Corn response to rotation with soybean was erratic, while sorghum did not respond to rotation with soybeans. Continuous doublecropping of soybean and wheat, and 2-yr. rotations of corn-wheat-soybean or sorghum-wheat-soybean were only marginally profitable when the summer crop was not irrigated, but highly profitable when the summer crop was irrigated. All cropping systems with sorghum were the most profitable when irrigation was not used, while all cropping systems with corn and/or wheat were the most profitable when irrigation was used. Impact: Results are being used by producers to make planting decisions for irrigated and nonirrigated production systems on the vast acreage of clay soils.

Accomplishment: Demonstrated that non-traditional April plantings (ESPS) of both MG IV and V soybean cultivars vs. traditional May or later plantings in the midsouthern USA result in significant yield increases and increased net returns when grown with or without irrigation. The increases were achieved with no extra input cost. These results indicate that the ESPS concept can be used to significantly and consistently increase soybean yield potential in the region. They are the first to demonstrate that success of the ESPS concept is dependent on early planting and use of cultivars in MGs IV and V. On the region's large clay-soil acreage, determined that the ESPS must be used in conjunction with the stale seedbed planting system. Impact: During the last 8 years, the ESPS has been used on an average of about 30% of the soybean acreage in the region. Use of the ESPS has resulted in more than $80,000,000 increase in income per year in the region (8 million acres x 30% ESPS x 6 bu/acre yield advantage x $6/bu.). From 1999 through 2004, 29, 24, 74, 50, 68, and 75% of Mississippi's acreage was planted using this concept. In Louisiana, the percentage planted by May 1 has increased to almost 50% in permitting years, while in Arkansas, the percentage has increased to ~25%. Requests for information pertaining to this concept have been received from South America and Asia.

Accomplishment: Technology Transfer: Lead editor of the 19-chapter book Soybean Production in the Midsouth (#96); Recipient of 2001 ARS Award for Superior Technology Transfer Achievement; 2002 Leader of the Year in Service to Miss. Agriculture Award presented by Progressive Farmer Magazine; 2004 Delta Council "Researcher of the Year". Impact: Book is a first of its kind, unique presentation, and a complete body of current knowledge pertaining to soybean production in the midsouthern US. Used by producers and colleagues in the region as an authoritative reference on important production practices. The Mississippi Soybean Promotion Board provided a $47,000 grant to purchase a copy of the book for each member of the Mississippi Soybean Association. Awards are for long-term research and dissemination of results to clients.
