Summary: Two soybean research trials were conducted near Scandia, KS, in both dryland and irrigated environments during the 2014 and 2015 growing seasons. The objective of this research was to study the contribution of different farming practices for developing efficient and high-yielding soybean production systems. Each experiments had five treatments: farmer practices (FP), comprehensive fertilization (CF), production intensity (PI), ecological intensification (EI = CF+PI) and advanced plus (AD). Yield gap, potential minus on-farm yields, is primarily defined by management practices (M) and their interactions with the environment (E). By selecting best management practices farmers can close on-farm yield gaps. This study evaluated the contribution of varying farming systems in developing efficient and high-yielding (yield and nutrient uptake) systems in corn-soybean cropping rotations.

Responsibility: United Soybean Board (USB) farmer-leaders develop and maintain partnerships with U.S. land grant universities and U.S. ag-focused research organizations such as the Plant Management Network to increase the transfer of checkoff-funded applied and practical production research information to U.S. soybean farmers. USB neither recommends nor discourages the implementation of any advice contained herein, and is not liable for the use or misuse of the information provided.
