Abstract:

In order to define different cultivation factors on the influence of board been in non-tillage rice field, orthogonal design of 4 factors, variety, planting density, sowing date and fertilizer, and 4 application amounts on yield and agronomic traits of board been were studied in no-tillage paddy field experiment. In this research, variety had greater effect on yield. The plant height was determined mainly by genetic factors and sowing date. The grain per plant was determined mainly by variety, density and fertilizer. The 100-seed weight was determined mainly by genetic factors. The optimum factor combination was SU-03021 applied with sown in October 22nd, calcium superphosphate 450 kg/hm2 and urea 75 kg/hm2 under the planting density of 1.27×105 hm2, in these conditions, the yield achieved 2725.2 kg/hm2.
