Tillage of alfalfa is practiced in many areas of Montana to control weeds and stimulate alfalfa growth. Results from around the country have been variable. Three tillage methods were compared in this study: deep, one-pass with a field cultivator; shallow, one-pass; one-pass discing. Increased tillage did reduce stand densities, but yields were not greatly affected due to plant compensation. Under no circumstances did tillage of a young vigorous stand significantly increase alfalfa yields compared to the control. Tillage did increase N and P concentrations in alfalfa, particularly in early spring.

This paper reports the results of a four-year experiment in crop rotation and cultivation methods conducted at eleven stations in the Great Plains area. Some of the questions asked of this experiment were how can the largest average yields of corn, spring wheat, oats and barley be obtained, do moisture conservation methods pay where continuous cropping to the same crop is practiced, and can green manuring be profitably substituted for summer tillage? The results found that a 3-year rotation of corn, wheat and oats gave the most profitable returns. Continous cropping with moisture conservation methods of fall plowing and fall, winter and spring tillage did not give results to warrant its recommendation. The most highly recommended practice was that of green manuring. For greatest benefits to the soil, it was recommended to plow in a green manure crop in early season, with little summer tillage, until wheat planting time.

Chem fallow was compared to stubble mulch and reduced tillage in a spring wheat-fallow rotation. Average surface residue prior to planting was three and two times greater than reduced tillage for chem fallow and stubble mulch, respectively. Chem fallow plots stored more soil water, but this did not increase yield during the study. During years of crop stress resulting from limited soil water, chem fallow may produce higher yields than stubble mulch. Grain water use efficiency was greater for wheat grown on stubble mulch plots than on chem fallow plots.
