Project Summary

This project is designed to better understand the interactions of two practices that showed to be a major soybean yield gaps (row spacing and planting date) and two input management strategies that showed to be non-profitable investments (high seeding rates and late season N fertilization). Nevertheless, conducting this research under irrigation will provide a valuable information to any farmer whose goal is to raise >80 bu/ac soybean. This research will also address farmers’ concerns regarding the impact of basic management practices on yield and yield components of dicamba-tolerant soybean.

Project Objectives

(1) Quantify the impact of planting date, seeding rate, row spacing, and nitrogen management on dicamba-tolerant soybean yield and yield quality in western NE.
(2) Develop scientific-based resources for growing irrigated soybean in a semi-arid environment, and ultimately,
(3) Increase adoption of soybeans in western Nebraska for a more sustainable agricultural production.

Project Deliverables

The short-term goal of this project is to get farmers attend our field demonstrations and start re-thinking and self-evaluating aforementioned management strategies in irrigated soybean. Intermediate goal would be to encourage farmers to increase the frequency of soybeans in their crop rotation, adopt best management practices, and have better yield and yield stability in the following 2-3 year periods. Ultimately, farmers in semi-arid climates will increase soybean acreage, enhance profitability, and implement environmental stewardship practices that benefit the soybean industry as a whole (long-term goal).

Benefit to Soybean Farmers

The proposed research is designed to primarily benefit soybean farmer in what is perceived to be a nontraditional soybean growing region (central and western part of Nebraska). Nevertheless, conducting this research under irrigation will provide a valuable information to any farmer whose goal is to raise >80 bu/ac soybean. This research will also address farmers’ concerns regarding the impact of basic management practices on yield and yield components of dicamba-tolerant soybean.
