Program overview

The Crop Science concentration within the Integrative Plant Science MPS focuses on applying knowledge of crop plants to optimize crop use of light, water, mineral nutrients, and temperature, and to limit diseases, weeds, and insects. 

Crop Science is the study of crop systems for growing food, feed and fiber crops. Field crops represent the largest sector of plant-based agriculture, therefore, crop scientists can choose from a wide range of professional opportunities that involve identifying traits and environmental factors that need optimization, using latest technology for monitoring and interpreting crop development and performance, and managing crops in a productive and environmentally responsible way.

CALS MPS program details

Cornell’s College of Agriculture and Life Sciences (CALS) Master of Professional Studies (MPS) program is an accredited, course-based, one-year master’s degree program that emphasizes professional development and intellectual investigation in the areas of agriculture, life sciences and global development. (The Integrative Plant Science MPS program is STEM-designated degree program.)

Though similar to a Master of Science (M.S.) degree in its academic rigor, the MPS degree differs from a traditional M.S. degree in its structure and focus. An M.S. is research-based, with students building a thesis over the course of two or three years. In contrast, the MPS degree is a one-year, course-based program where students study the intricacies and in-depth questions of their field of study. Instead of a thesis or research project, MPS students complete a capstone project during their final semester. To understand this difference in greater detail, please visit our FAQ page.

MPS students are part of a community of diverse students and faculty who share common goals, connecting research and practice to solve complex problems. 

The Integrative Plant Science Master of Professional Studies program is a STEM-designated degree with coursework requirements that differ slightly from other MPS programs at Cornell.

Concentration Courses

12 credit minimum of Primary and Secondary with at least 5 credits from Primary.

  • PLSCI 6017 Cropping Systems Ecology (1 credit) - Crop ecology is the integrative study of biological, physical, social, and technological factors that govern the emergent properties arising from cropping systems at different spatial and temporal scales. It implicitly recognizes that achieving the goals for multi-functional (i.e. 'sustainable') agriculture cannot be achieved without understanding the functional interdependencies among these factors. This course serves as a graduate-level synthesis of 1) how crop and crop communities are influenced by the physical and chemical growth environment, 2) how the growth environment is modified by agronomy and, in turn, 3) how production processes are shaped by both managed and unmanaged factors. Readings and class discussions of key concepts compose the first half of the course, with the hands-on application of systems analysis tools emphasized in the second half.
  • PLSCI 5440/ENTOM 5440 Integrated Pest Management (4 credits) - Lectures integrate the principles of pest control, ecology, and economics in the management of pests across multiple systems. Labs consist of exercises to reinforce concepts presented in lecture and demonstrate pest monitoring techniques and the application of computer technology to management problems.
  • PLSCI 5210 Soil and Crop Management for Sustainability (3 credits) - Students learn about agronomy and recent advances in sustainable soil and crop management, and gain a lot of practical farming knowledge. Integrated perspectives on the physical, biological, and chemical aspects of soil management in the broader context of agroecosystems are explored. Soil and crop management practices and resulting interactions between soil, water, organisms, and organic and chemical inputs form the basis for discussions on diverse cropping systems, soil health, water quality and quantity, bioenergy, greenhouse gases, and sustainability.
  • PLSCI 5150 Weed Biology and Management (4 credits) - This course examines components of the biology, ecology, and management of weeds in crop and non-crop ecosystems, particularly in the Northeastern United States. The first part of the course focuses on biological/ecological factors that govern seed dormancy, plant growth, population dynamics, competitiveness, reproduction, and survival. Close attention is given to accurate identification of plants and to characteristics that make weeds competitive, undesirable, or both. The second part of the course examines strategies to control weeds, including their benefits and drawbacks. Aspects of chemical control, including classification, mode of action, selectivity, symptomotology, and resistance, are presented. Herbicide-tolerant crop (i.e., GMO) issues and health and environmental concerns of herbicide use are addressed. The use of integrated approaches to weed management is emphasized.
  • PLSCI 5140 Global Cropping Systems and Sustainable Development (3 credits) - With accelerating demands for food, feed, and fiber along with increasing recognition of the importance of agricultural systems to ecosystem services and rural livelihoods, the requirements of agricultural systems are simultaneously intensifying and diversifying. This course introduces foundational concepts that explain the distribution, productivity, and ecological impacts of the world’s major cropping systems from an interdisciplinary perspective, including soils, climate and water, markets, policies, and institutions. Through systems thinking and process-based agronomy, an emphasis is placed on assessing solutions for resolving core challenges to the sustainable development goals in the context of global change. Students gain insights into sustainable intensification technologies as well as the social process that support innovation. Evidence synthesis through a geographically-anchored case study and active participation in class discussions are required.
  • PLSCI 5110 Field Crop Systems (4 credits) - Principles of field-crop production of major crops used for food, feed, fiber and bioenergy. Includes introductory concepts of plant growth, development and maturation as they relate to crop performance and management, adaptation to soil, climatic and environmental conditions, tillage, mineral nutrition, pests, cropping sequences, management systems, and crop improvement. Grain, oilseed, biofuel and forage crops are emphasized. Laboratory includes field trips and demonstrations of the most important crop species, morphological and growth characteristics essential to environmental adaptation and response to management.
  • PLSCI 6420 Mineral Nutrition: From Plants to Humans (3 credits) - Plants provide almost all essential minerals for humans and therefore plants are critical components of the human diet. Plant biologists address challenges of meeting the nutritional needs of the increasing world’s population by studying plants’ ability to uptake, translocate and accumulate mineral nutrients in edible tissues. By integrating basic plant biology with molecular breeding and genomics approaches, fundamental discoveries are utilized to have the greatest impact on solving biofortification of plant-based foods. This team-taught course explores the mechanisms of acquisition of mineral nutrients from the soil, translocation and accumulation in plant tissues, strategies to prevent mineral element deficiencies while avoiding their overload, and toxicity of noxious metals. Selected lectures focus on the relation between the nutrient status of plants and human nutrition and health.
  • PLSCI 6140 Weed Ecology and Management (3 credits) - Examines plant ecological principles governing weed population dynamics and weed-crop competitive interactions in crop and non-crop ecosystems. Development of sustainable weed management strategies.
  • PLSCI 6030 Genetic Improvement of Crop Plants (3 credits) - Genetic enhancement of crop value to humans began with domestication and continues with farmers' variety development and scientifically trained plant breeders' applications of Mendelian, quantitative, and molecular genetics. This course examines crop genetic improvement methods by discussing the history and current practice of plant breeding, tools available to breeders, choices and modifications of those tools to meet specific objectives, and challenges plant breeders face in developing varieties for the future.
