Book Description
Efficient use of agricultural inputs involves correct decisions on what production systems would give optimum yields. Good management decisions can only be made by considering information provided by research on crop responses to management practices. Field studies were conducted to determine the influence of planting date, row spacing, cultivar, seed treatment, depressing plants with tractor tires, and planting patterns on yield, seed quality, and agronomic characteristics of soybeans (Glycine max (L.) Merr.). In Experiment 1 (1981 to 1982), treatments were five planting dates (May to July), row spacings (12,18, 38, and 76 cm), and cultivars ('Evans', 'Hodgson 78', and 'Corsoy 79'). The 18 cm plots were in pairs. One plot was planted with seed treated with Vitavax (5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide). 'Wells' was planted in Experiment 2 (1979 to 1980). Treatments were morning and afternoon, and growth stages when plants were depressed in 25 cm rows. In Experiment 3, four rippled canopies were compared with pure stands and blends of 'Wells II', 'SRF 200', and 'Gome' in 38 and76 cm row spacing in 1981 to 1982. In Experiment 4, six cultivars were planted in pairs in 38 cm rows, perpendicular to each other. In Experiment 5, seed from Experiment 1 was assayed for Diaporthe and Phomopsis infection and for germination. Delayed planting reduced yield. Narrow rows yield highest. Cultivars did not differ in yield. Yield in late planted narrow rows, with 'Evans' and 'Hodgson 78', was not reduced as much as in the 76 cm rows. Seed treatment did not influence yield or other characteristics. Morning and afternoon treatments were not different. Depressing plants did not reduce yield until flowering. Since most postemergence applications are done before flowering, yield reduction is compensated for by adjacent rows. Canopy designs were not different in yield. Light penetration was not affected by canopy designs. Crisscross planting did not affect yield. Direction of row changed competing ability of cultivars. Delayed planting reduced Phomopsis infection and improved germination. Seed quality in narrow rows was equal to or better than in wide rows. 'Evans' had more infection and lower germination than 'Corsoy 79'. Full season cultivars or delayed planting produced seed of good quality.
