Background

This exploratory project was initiated in the spring of 2022 to evaluate the feasibility of upland rice production in southern Alberta. Trials will use Seed Film Cultivation (SFC) technology to suppress weeds, increase soil temperature, and reduce evaporative moisture losses. Rice grown with SFC will be compared to direct seeded plots and transplanted rice seedlings. Irrigation will be provided by an overhead pivot system or by sub-surface drip irrigation. Plant growth parameters and yield will be assessed, and this work will inform future research required to establish a rice production industry in Alberta. Rice grown using SFC technology reduces the water demand for producing the crop, and perhaps more importantly, reduces the methane (greenhouse gas) associated with flood irrigated rice production.

Methods

2022

A fertilizer blend of 100 lbs/ac N (46-0-0) and 30 lbs/ac P (11-52-0) was broadcast immediately before planting. The rice was direct seeded at 80 kg/ha which is approximately 364 seeds/m2 (TSW = 22 g/1000 seeds). The transplants were spaced approx. 9” apart as recommended to allow for greater tillering and the seed film utilized a cluster of seeds at each opening of the film (approx. every 9”).
