Evaluation of quantitative and qualitative yield of maize under conventional, integrated and in conversion to organic production systems
Message:
Abstract:
This investigation was carried out to study the qualitative and quantitative performance of two varieties of forage maize under conventional, integrated and in conversion to organic production systems in summer of 2010 in Pishavar (in Varamin). The experimental design was split-plot, based on Randomized Complete Block Design (RCBD) with three replications. Treatments consisted of production systems (conventional, integrated and in conversion to organic) located in the main plots and two varieties (single cross 704 and single cross 260) arranged in the sub-plot. In conventional production system only chemical inputs were used. For integrated production system, chemical, organic and biologic nutrients were used together. But for organic production system, only biological organic inputs were applied. Results showed that maximum values ​​for dry forage yield, wet forage yield were respectively related to the integrated production systems and the highest plant height obtained from conventional production systems, respectively. The results showed that single cross 704 have maximum values for all measured traits than single cross 260, except for nitrogen content in the leaves.
