Effect of Organic and Inorganic Fertilizer on Growth of Linseed (Linum Usitatissimum L.) Under Poplar Based Agroforestry System.

A field experiment was conducted with linseed under Poplar during Rabi season of 2018 at crop Research Farm, Department of Silviculture and Agroforestry, SHUATS, Prayagraj, (U.P.). The treatment comprised of FYM 100%, NPK 100%, Control, VC 100%, NPK 50%, FYM 50%, VC 50%, NPK 75%, FYM 75%, VC 75%, NPK 125%, FYM 125%, VC 125% under Poplar based Agroforestry. The experiment was laid out in Randomized Block Design (RBD). The result Showed that maximum plant height (cm₂), plant diameter (cm) recorded at 30, 60, 90 and 120 DAT, capsule per plant, seed per capsule were recorded. The treatment (T₁₁) with application of (FYM 125%) showed the significant superiority in giving the maximum plant height (58.41cm at 120 days), plant diameter (4.43cm² at 120 days), capsule per plant (48.93 at 120 days), seed per capsule 9.33. The treatment (T₂) with application of (NPK 100%) showed the significant. These parameters were significantly influenced by different sources and doses of organic and inorganic fertilizer. However, Poplar based Agroforestry system could be rank based on economic performance of linseed also recorded in treatment T₁₁ (FYM 125%).
