Effects of different tillage management on the growth and yield of maize (Zea mays l.)

Effects of different tillage management on the growth and yield maize were studied from early June to September 2017. The experiment was set up with three treatments: traditional shallow moldboard plow straw removal (MT), sub-soiling/ /sub-soiling rotation mulch (ST) no-till/sub-soiling/no-till retention (NT). soil compaction layers, plant height, chlorophyll content, above-ground biomass determined through practices. Results showed that NT ST treatments helped reduce compaction, had a positive effect root development, height content compared MT treatment. value in period under increased by 31.8 24.6%, respectively, 20.2 15.9% MT, respectively. size order > ST, maximum at 20 cm treatment, which 1007 kPa. Meanwhile, also maize. Compared dry weight plants for significantly 24.3 15.7%, grain 11.9 14.9%, respectively (P < 0.05). are effective measures improve structure soil, contribute development thereby increase yield.
