Aim: This study aimed to evaluate the effect of different levels of nitrogen and filter mud cake applications on vegetative growth and yield on tomato cultivar "Castle Rock".
Place and Duration of Study: Field experiments were conducted during two successive winter seasons 2015/2016 and 2016/2017 at the experimental farm, Faculty of Agriculture and Natural Resources, University of Bakht Alruda, Ed Duiem, Sudan.
Methodology: Treatments included three Nitrogen levels (0, 43 and 86 kg N/ ha) and three filter mud levels (0, 2 and 4 ton/ ha). Urea (46%N) was used as source of nitrogen and applied after fifteen days from sowing. Filter mud cake was applied one month before sowing. The treatments were arranged in a randomized complete block design with three replications.
Results: Results showed significant differences among N treatments in tomato vegetative growth, yield and yield components in the two seasons. The 86 kg N/ ha showed the highest vegetative growth yield and yield components compared to control. The filter mud application at both rates showed significant increase in the most vegetative growth parameters, yield and yield components compared to the control in the two seasons. The combination of N and filter mud resulted in significant increase in vegetative growth and yield components, the highest values were obtained by application of 86 kg/ha combined with 4 ton filter mud /ha.
Conclusion: Considering the present study it can be concluded that the application of 86 kg/ha combined with 4 ton filter mud /ha is the best level in terms of maximum vegetative growth, yield and yield components of Castle Rock tomato cultivar.
