Effects of Biozyme (Ascophyllum nodosum) Biostimulant on Growth and Development of Soybean [Glycine Max (L.) Merill]

摘要

Field experiment was conducted to investigate the effects of Biozyme(TM) on soybean. Application of Biozyme granule and crop-plus spray with half of recommended nitrogen, phosphorus, and potassium (NPK) showed significant effects on all the growth and yield parameters of soybean. The greatest value for the number of trifoliate leaves (29.95leavesplant(-1)), leaf area (1818.21cm2plant(-1)), leaf area index (5.946), total chlorophyll content (1.995mgg(-1) leaf fresh mass), number of nodules (35.086plants(-1)), fresh and dry weight of nodules (0.664 and 0.1592gplants(-1)), dry weight of root (8.564gplants(-1)), pods plant(-1) (69.0), seeds pods(-1) (3.25), straw yield (3.122tha(-1)), biological yield (6.349tha(-1)), and grain yield (3.277tha(-1)) was observed with Biozyme crop-plus spray at 500mLha(-1) plus half of recommended NPK and were significantly greater than control values. Biozyme crop-plus spray at 500mLha(-1) plus half of recommended NPK performed better compared to other treatments.
