Abstract:
A two year field experiment on basmati rice was conducted to investigate the impact of various organic, inorganic and integrated nutrient amendments on growth parameters i.e. plant height, leaf area index (LAI), leaf dry weight, shoot dry weight and total dry matter (TDM). Basmati rice was grown in completely randomized block design with four replications for each treatment. Six treatments i.e. T1 [100 kg N through green manure (GM) + 25kg N ha^-1 through vermicompost (VC)]; T2 [50% N GM + Beejamrit + Ghanjeevamrit @ 250 kg ha^-1 + Jeevamrit @ 500 L ha^-1/time]; T3 [50% NPK GM + 50% chemical fertilizer]; T4 [25% nutrients through organic + 25% nutrients through inorganic sources + Beejamrit + Ghanjeevamrit @250 kg ha^-1 + Jeevamrit @500 L ha^-1/time]; T5 [Recommended doses of NPK (120:60:40) kg ha^-1]; T6 [Recommended doses of NPK (120:60:40) kg ha^-1 + Farm yard manure (FYM) @ 5 t ha^-1] were applied. The results revealed that maximum plant height, LAI, leaf dry weight, shoot dry weight and total dry matter (TDM) was in T3 which was at par with T5. The values of all the growth parameters were lowest in organic treatments T2.
