Photosynthetic Activity, Nutrient Concentration, Yield and Soil Properties Altered by Long Term INM Practices of Knol-khol (Brassica oleracea var. gongylodes L.) under Acidic Inceptisols

A long-term field experiment was started in the campus of College Agriculture, OUAT, Bhubaneswar, Odisha since kharif 2010 a randomized block design with 08 treatments and three replications under cereal-vegetable-pulse cropping system. Different observations on plant soil parameters were taken during 2018 to evaluate performance test crop towards different package practices followed. The Knol-khol, 25th sequence. T1: Control, T2: Soil Test Dose (STD), T3: STD + Farm Yard Manure (F), T4: Vermicompost (VC), T5: F Biofertilizers (BFs), T6: VC BFs, T7: L T8: BFs which consisted combinations inorganic fertilizers, organic manures (FYM vermicompost), ameliorant (lime) biofertilizers. Knol-khol grown experimental plot fertilizers as per treatment plans. Leaf samples from collected at 45 days after planting (DAP). economic yield highest (3.44 t ha-1) supplied source nutrient lime (T7) par T8 (3.34 whereas significantly higher than rest other lowest obtained (1.45 ha-1). values 2.68%, 1.11mg g-1 fresh leaves 46.34 recorded for leaf nitrogen content, chlorophyll content SPAD value respectively T7 1.91%, 0.54 mg 21.81 T1. However, properties harvest found be better where vermicompost integrated fertilizer lime.
