Effect of different level of organic manures and inorganic fertilizers on growth, yield and quality of Spinach (Spinacia oleracea)

The present experiment was carried out during November, 2019 to January, 2020 in Research Field, Department of Horticulture, SHUATS, Prayagraj. The experiment was conducted in Randomized Block Design (RBD), with ten treatments replicated thrice with (FYM+Vermicompost+NPK) and variety on Hybrid palak. The treatments were T1 (RDF (NPK- 60:60:60 kg/ha) FYM (10 ton/ ha), T2 (NPK (45:45:45 kg/hac) + 2.5 ton FYM), T3 (NPK (45:45:45 kg/hac) +1.5 ton VC), T4 (NPK (45:45:45 kg/hac) + 1.5 ton FYM +0.75 VC), T5 (NPK (30:30:30 kg/hac) +5 ton FYM), T6 (NPK (30:30:30 kg/hac ) +2.5 tonVC), T7 (NPK (30:30:30 kg/hac) + 2.5 ton FYM +1.5 ton VC), T8 (NPK (15:15:15 kg/hac) +7.5 ton FYM) T9 (NPK (15:15:15 kg/hac) +3.5 ton VC) and T10 (NPK (15:15:15 kg/hac) + 4 ton FYM +2.25 ton VC). From the present investigation it is concluded that the treatment T5 (NPK (30:30:30) + 5 ton FYM) was best in growth, yield and quality parameters of Spinach, followed by treatment T6 (NPK (30:30:30) + 2.5 ton VC) and minimum growth, yield and quality was recorded in treatment T1 (NPK (60:60:60) + 10 ton FYM), in terms of economics treatment T5 was best with benefit cost ratio 2.43.
