About

Guy Collins is a Professor and Cotton Extension Specialist in the Department of Crop and Soil Sciences at NC State University. His research focuses on cotton production and management, including cotton growth, development, and yield, particularly under high thrips pressure. He is involved in extension activities related to cotton and other crops, providing expertise and guidance to improve crop management practices. Collins has contributed to the field through numerous publications on topics such as planting patterns, pest management, seed treatment, and fertilizer optimization, supporting sustainable and efficient crop production in North Carolina.

• Maximizing soybean yield by understanding planting date, maturity group, and seeding rate interactions in North Carolina

  Crop Science · 2021 · 39 citations

  Abstract Growers across theU.S. Southeast use a diversity of soybean [ Glycine max (L.) Merr.] planting dates, maturity groups, and seeding rates for soybean production depending on their rotational complexity. Studies were conducted across seven North Carolina environments in 2019 and 2020 to determine the effect of planting date (mid‐March through mid‐July), maturity group (MG 2–8), and seeding rate (185,329–432,434 seeds ha –1 ) on soybean emergence, stand, and yield. Across environments, soy…

  Pest Management Science · 2021 · 17 citations

  BACKGROUND: Helicoverpa zea (Boddie) damage to Bt cotton and maize has increased as a result of widespread Bt resistance across the USA Cotton Belt. Our objective was to link Bt crop production patterns to cotton damage through a series of spatial and temporal surveys of commercial fields to understand how Bt crop production relates to greater than expected H. zea damage to Bt cotton. To do this, we assembled longitudinal cotton damage data that spanned the Bt adoption period, collected cotton d…

• Response of agronomic crops to planting date and double‐cropping with wheat

  Agronomy Journal · 2020-02-03 · 11 citations

  article

  Abstract Planting date can affect crop yield and is an important management decision for practitioners. Although wheat ( Triticum aestivum L.) and soybean [ Glycine max (L.) Merr.] can be effectively double‐cropped in North Carolina, if commodity prices and projected economic returns are higher for crops other than soybean, growers might consider a nontraditional, double‐crop system. Direct comparisons of major agronomic crops with different planting dates or in a double‐crop system with wheat a…
