Johnsongrass (Sorghum halepense (L.) Pers.) seed yield and seasonal seed production pattern were studied in two maize crops, an oat crop stubble and an unsown field using periodic harvests from permanent quadrats. The rates of seed and panicle production were strongly dependent on season and system. Two main periods of seed and panicle production were observed: the first, in early summer, lasted ca. 10 days and produced approx. 60% of the total seed yield; the second, at the end of the summer—early autumn, lasted ca. 40 days. The number of seeds per panicle was larger in early summer than in late summer—early autumn in all the studied situations. Johnsongrass produced more panicles and seeds under the maize crops than in the other agricultural systems. The influence of climatic conditions and crop system on seed and panicle production patterns is discussed.
