| Abstract | ||
| Economical wheat yield increase had become urgently necessity with conservation of soil production. This is necessary so it is to apply many techniques such as regularization of agricultural machinery. Thus, this research study conducted to derive the growth and yield of five wheat cultivars over two tillage systems. Where the trial contained two factors, those are the first is cultivars viz. adena, azar, pura, cymto and Iraq, the second one is two tillage systems viz. tillage and non-tillage. The levels of two factors were subjected to randomized distribution using split block design in RCBD with three replicates. Results derived that Azar performance was the most superior in plant height of 96.34 cm, flag leaf area of 654.39 cm2, spike length of 12.67 cm and grains no of 57.83 grain spike-1. While Cymto was gave the biggest grain weight per spike of 3.02 g spike-1. Adena was superior in thousandth grain weight of 91.17 g and experimental unit yield of 770.20 g 4 m-2. Furthermore, tillage achieved the best plant height of 93.87 cm, flag leaf area of 544.50 cm-2, grain weight per spike of 2.41 g spike-1, thousandth grains weight of 62.53 g and experimental unit yield of 781.10 g. Moreover, interaction has significantly effect that Iraq cv was superior in plant height of 100.67 cm under till system, whereas Azar gave highest flag leaf area of 686.22 cm2 and spike length of 13.67 cm under no-till. Cymto was superior in grains weight per spike of 3.16 g spike-1 and experimental unit yield of 981.10 g 4 m-2 under till system. Adena was achieved the heaviest thousandth grains of 144.00 g under till system. | ||
