Establishment of a Rice Tiller Number Prediction Model Using Soil Compaction and Days after Transplanting

Soil compaction has a real effect on rice growth in the Mekong Delta. The correlation between soil and (tiller number plant height) paddy field An Giang province was evaluated 2020 Winter-Spring Summer-Autumn crops using Pearson's test. research results show that 0-20 cm from surface positive with tiller number, while height is non-significant. Therefore, prediction model for numbers constructed Curve Fitting application Matlab software. obtained models can effectively predict of tillers value layer at times under 40 DAT two studied crops. This study provides optimal (about 229.8 337.6 kPa these crops), which aid utilization tillage cultivation by farmers.
