Dynamic role of organic matter and bioagent for the management of Meloidogyne incognita–Rhizoctonia solani disease complex on tomato in relation to some growth attributes

Figures & data

Figure 1. Soil application of N. indicum and T. harzianum on disease complex involving M. incognita and R. solani on growth parameters (Plant length, fresh weight, fruits/plant, dry weight) of tomato

Notes: NI = Nerium indicum, MI = Meloidogyne incognita, RS = Rhizoctonia solani, TH = Trichoderma harzianum; values followed by different letters are significantly different over control.
