تأثير نظام الزراعة الحافظة في مؤشرات النمو و الإنتاجية بالمقارنة مع نظام الزراعة التقليدية لمحصولي القمح القاسي و الحمص

الملخص EN

In order to study the effect of conservation agriculture on growth parameters and productivity of durum wheat in rotation with chickpea crop comparing with conventional tillage system, field experiments were conducted in Izraa Research Station affiliated to the Arab Center for the Studies in Arid Zones and Dry Lands (ACSAD), during two consecutive growing seasons (2010/ 2011 and 2011/ 2012).

The experiments were laid out according to randomized complete block design (RCBD) with three replications.

The results of the study showed that there were no significant differences between conservation and conventional agriculture systems in the mean number of days for maturity and plant height of durum wheat plants.

However, for 1000-kernel weights, grain yield and biological yield, there were significant differences between the two farming systems.

Thus, under conservation agriculture system, the values for the mentioned parameters were (45.47 g, 2326.67 kg.ha-1 and 8033.33 kg.ha-1 respectively), and for the conventional agriculture, the values were (39.50 g, 1643.33 kg.ha-1 and 6333.33 kg.ha-1 respectively).

With respect to chickpea crop grown in rotation with wheat crop in the second season, the highest seed and biological yield were recorded under conservation agriculture system (802.13 kg.ha-1 and 2561.31 kg.ha-1 respectively) compared with conventional system (628.33 kg.ha-1 and 2199.67 kg.ha-1 respectively).

This highlights the importance of applying conservation agriculture system as integrated package of practices for improvement growth and productivity parameters of durum wheat crop grown in rotation with chickpea crop.
