Seed Yield and Caryopsis Weight of Side-Oats Grama

Abstract

Insect control, row spacing, and nitrogen fertilization were studied. Insect control increased seed set and seed yields of side-oats grama. Seed set and seed yields per acre were higher but caryopsis weight was lower from plantings in solid stands than from spaced rows. Nitrogen fertilizer maintained seed quality and increased seed set and yields of cleaned seed. Cultural practices to obtain maximum development of caryopses, as well as large yields, should be utilized because of the great importance of seed quality in stand establishment.
