TAILIEUCHUNG - Effect of different tree spacings of Grewia Optiva and combined doses of poultry manure and vermicompost on growth and yield of bell pepper under agrisilviculture system

A field trial was established to study the effect of four spacing (8m×1m, 8m×2m, 8m×3m and open . tree less area) of Grewia optiva trees, and eight manure doses treatment (T1 to T6 - 160 %, 140 %, 120 %, 100 %, 80 %, 60 % of recommended doses of nitrogen through vermicompost and poultry manure in 50-50 ratio respectively, T7- 100 % of recommended doses of NPK (chemical fertiliser) and T8- Control . no manures and fertilisers) on growth and yield of bell pepper under agrisilviculture system. The benefit cost ratio increased upto T3, and then after decreased depicting that 120 % of the recommended doses of nitrogen through vermicompost and poultry manure was the best treatment for the optimum yield of bell pepper, both under different spacings of agrisilviculture system and open condition. Agrisilviculture system integrating bell pepper with widely spaced Grewia optiva . 8m×3m was found to be economically superior to sole cropping of bell pepper in open condition. | Effect of different tree spacings of Grewia Optiva and combined doses of poultry manure and vermicompost on growth and yield of bell pepper under agrisilviculture system
