The effect of chlorocholin chloride in four wheat cultivars

Abstract

Field experiments were employed investigate the effect of three nitrogen levels (60, 90 and 120 kg/ha of N) in combination with four chlorocholin chloride (CCC) levels (0, 2, 3 and 4 kg/ha of active ingredient) in four different wheat cultivars (IAS 54, IAS 20-Iassul, IAS 50-Alvorada and Toropi). The chlorocholin chloride reduced the wheat plant hight, causing stem thickness and inter-node shortness. These effects resulted in a higher resistance to lodging, when higher levels of nitrogen fertilizer were used. The cultivars tested did not increase yields when levels of nitrogen higher than 60 kg/ha were applied. The application of chlorocholin chloride increased the wheat yields of the cultivars studied significantly.
