Influence of CMS as a biostimulant on cabbage production (Brassica oleracea var .capitata) under surface irrigation system

Abstract

At a private farm, Sayed Ramadan in Ayat, Giza governorate, Egypt, two field experiments were conducted in the winter of 2021-2022 and 2022–2023 to investigate the influence of CMS compound on the growth and yield characteristics of cabbage. The nutritional balance attained by spraying CMS compound often resulted in a physiological improvement in the cabbage crop (Brassica oleracea var .capitata)., as evidenced by the crop’s features when compared to the control on clay soil. The application of CMS, as a yeast by product, at a rate of 15 ml/l produced the greatest, head circumference (26.61%) and (22.88%), head weight (119.23%) and (126.45%), SPAD (45.72%) and (12.80%), yield ton/ feddan (39.36%) and (43.10%), N (99.87%) and (21.52%), P (43.33%) and (74.79%), K (81.14%) and (14.55%), Fe (7.19%) and (4.72%), Mn (14.81%) and (32.88%), Zn (25.93%) and (23.93%), in cabbage compared with control in both seasons, respectively. Economically, CMS compound at rate gave the net returns (45439 L.E. /fed) and (56864 L.E. /fed) in the both season respectively compared with control and other treatments.
