| dc.description | Mathematical models were tested to correlate the leaf area index (LAI) of maize to the percentage of light intercepted by the canopy (% LIC) and this with the total dry matter of aerial parts (TDM), as well with the grain yield (GY). The experi ment was conducted in a randomized block design, with four replications. The treatments consisted of hybrid maize at five pl ant densities: 4.0, 2.66, 2.0, 1.6, and 1.3 plants per m 2 (pl m -2 ). At densities of 4.0 and 2.66 pl m -2 , the average LAI and TDM did not differ among themselves but were significantly higher than th ose presented at the densities of 2.0, 1.66 and 1.3 pl m -2 , which also did not differ among themselves . The number of corncobs per plant (cob pl -1 ) and GY behaved similarly. The LAI grew exponentially with the plant density. For all ages of plants, the exponential model fit well with the % LIC values according to the LAI and also fit we ll to the data of dry mass as a function of % LIC. GY depending on the density fit well to quadratic, exponential straight line and logarithm-modified equations, and the number of cobs per plant depending on the density fit well to hyperbolic and exponential-modified equations. | |
