Effect of Different Nitrogen Percentage Input On Soil Fertility, Plant Nutrients and Yield of Organic Spinach (Amaranthus Spp.)

Nitrogen (N) management is important to assess the N effect on soil and plant under organic farming system. With this in mind, a glasshouse experiment was conducted determine of various inputs selected chemical properties, nutrient content yield spinach (Amaranthus spp). The experimental treatments were focused different percentages input (2, 4 6% from sources) with alone as control. applied 14 days after seeding (14-DAS) at recommended rate 2 t/ha. study result found that 4-6% (with T3 T4) had improved parameters such pH, CEC, total N, available-P exchangeable-Ca. Further, (cultivated organically), well yield, significant. Study findings have shown within 4% promotes quality, nutrients (leafy vegetables), can be scaled up farm level sustain system productivity.
