Analysis of Principal Components for the Assessment of Silage Corn Hybrid Performance under Water Deficit

Corn is an important crop for animal production systems. Owing to climate change, it understand the behavior of commercial corn hybrids under low soil water availability. The objective this study was evaluate morphogenic characteristics and yields silage subjected different conditions using univariate multivariate analyses. experimental design randomized blocks in a 5 × 2 factorial scheme with four replications. (AGRI104, AGRI320, AGRI330, AGRI340, AGRI360) replacement levels (50% 100% evapotranspiration—ETc) were considered as factors. A level 50% ETc defined severe deficit that persisted 46 days from V7 until harvesting (R3). Plant height, stem diameter, leaf area, chlorophyll index, productivity, fresh dry mass, matter shoot root systems evaluated. An analysis variance mean test isolated variables carried out, perspective, through principal components performed. In general, changed morphophysiological plants; however, only possible classify analysis. best performing hybrids, regardless levels, AGRI340 AGRI360.
