They concluded that spacing also influenced the seed and oil content in sunflower. In 2 of the 4 years, total water use was greatest and average soybean yields were least Prom the 15-cm row width. • Drill seeds along the furrow at a spacing of 3-5 cm between seeds. Generally, the highest seed yield was determined at 25 cm row-spacing where it was on average 1.90 t ha . The sowing should be done at a spacing of 45-60 cm between rows and 5-10 cm between plants depending upon seed size and season. Field studies in 2001 and 2002 evaluated the effect of soybean seeding rate and row spacing on the emergence, growth, and competitiveness of eastern black nightshade (EBN) in soybean. It is recommended not to drill beans and use a tolerant variety to white mold if a specific field has a history of white mold. soymilk and tofu) where the potential for large price premiums exist. Reducing seeding rates in 19- or 76-cm row soybean below the optimum rate may reduce soybean competitiveness with weeds, and indirectly increase production costs to the grower. On an average over the genotypes, the row spacing of 30 cm showed the highest seed yield in soybean under Bangladesh conditions. It should be a surprise, that the majority of the farmers in Iowa still use 30 inch row spacing despite research across the Midwest that has shown an advantage of narrow row spacing. Ames, IA 50011-2031 In mixed cropping of maize and soybean, plant maize at 100 cm row spacing keeping plant to plant distance 10 cm and three rows of soybean in … Spacing is dependent on the method of planting used. Climate change, new varieties, better technological abilities, and increased demand for local resources provide significant reasons to introduce soybeans in northern regions, above the typical soybean distribution area in Europe. The general belief is that reducing row spacing affects the competitiveness of both crops and weeds. A fact sheet can be downloaded (pdf file) on soybean row spacing. Field studies of Wayne, Stein, Williams, and Gold Harvest soybean varieties were made in 1985. Combining winter wheat row spacing of 14 cm with soybean row spacing of 18 cm and soybean row spacing of 27 cm is a highly suitable planting system for the plains of Northern China. 2150 Beardshear Hall In Mississippi, a narrow row spacing of 15-inches (<40-cm) was important to optimize yields with indeterminate varieties as part of the Early Soybean Production Arif et al., (2012) carried out a field experiment on three different plant spacing (5,10 and 15 cm) and three different row spacing (10,20,30 cm) in white mustard. USA row spacings vary from 25 cm to 100 cm, depending on locations, seeding time and machinery available. The predicted drop in yield was 30 kg/ha for each degree Celsius over 35.6 o C For the 25-cm rows, soybean yield in the plots infested with Rhodes grass beyond 3 WAP was 30–36% less than under weed-free condition. Use seed rate of 25-30 kg for sowing in one acre land. There were vary significant inflence (p < 0.05) of row-spacing on seed yield. 888 0 obj <>/Filter/FlateDecode/ID[<3B22D1B5B88CC44AAFC428A822DC904D>]/Index[850 78]/Info 849 0 R/Length 155/Prev 325673/Root 851 0 R/Size 928/Type/XRef/W[1 3 1]>>stream (P = 0.05) 0.200 n.s. Poke holes into a cultivated bed or row to plant soybean seeds about 2 inches (5 cm) apart and one-half inch (1 cm) deep. In the present study, as row spacing decreased from 70 to 30 cm, the lowest pod height increased from 8.8 to 16.1 cm in double-cropped soybean. While sowing use row to row spacing of 45 cm and plant to plant spacing of 4-7 cm. c��8�ɓ��q ��\n#�����2��,ggx��Vwq{:cc$�J��� FG�'�����1�fx��1�1��,��7`�-�͌�n�\B��%���@� �a�e�R� ��1�@�K�+�*��@ڞ��?�Ϙ� X&�i�W �81�|��� ` �iq� Faster soil coverage was obtained with a high seeding rate or narrower row spacings. Generally, the highest seed yield was determined at 25 cm row-spacing where it was on average 1.90 t ha .
