Analysis of agronomic variables of Ocimum basilicum L. under alternative tillage systems and standard organic practices

摘要

Little is known about the patterns of growth and development of basil (Ocimum basilicum) in arid environments. Even less is known when growing this crop under organic standards and conservational alternative tillage systems. An experiment on a certified-organic-field with three different systems of tillage was conducted on the Mexican state of Baja California Sur (BCS), with prevailing arid condition. Growth traits and yield of seeds of one most-usedcultivar (Nuffar) of basil in BCS were analyzed by employing principal components analyses (PCA). PCA showed a significant positive interaction of yield of seeds and foliar dry weight. PCA also showed a negative interaction of foliar area (FA) and number of knots. By using Pearson correlations the same interactions were identified plus positive correlations of plant height (PH) with number of knots, PH with FA, and PH with number of inflorescences.
