This project evaluated the effects of soil amendments for the management of weeds and diseases complimenting other efforts including organic soil amendments with poultry refuse and mustard oil-cake which can effectively control soil-borne diseases.
To evaluate the effects of soil amendment practices on weed proliferation and their role as latent hosts of soil-borne diseases, and overall suppression of soil-borne diseases of vegetable crops through soil amendment.
On-farm trials in tomato showed that organic soil amendments with poultry refuse and mustard oil- cake did not induce weed proliferation, nor did they cause higher disease incidence when compared with the farmer practice. Two hand weedings at the early vegetative and flowering stages of the crop effectively controlled thepredominant weeds,andreduced weeding costs without reducing the yields. The farmers received better economic returns by using this practice.
