Changes in amino nitrogen, protein and starch content of rice var. ADT 36 as influenced by application of integrated approaches and Bipolaris oryzae inoculation

Abstract

The Pot culture studies were undertaken to investigate the changes of amino nitrogen, protein and starch content in rice as influenced by application of Zinc sulphate and foliar application of salicylic acid and Potassium silicate and Brown spot pathogen Bipolaris oryzae inoculation. The results revealed that Soil application of Zinc sulphate @ 25 kg/ha along with foliar application of plant activator Salicylic acid @ 50 ppm on 15 days after transplanting and Foliar spray of silicon based nutrient potassium silicate @ 3% recorded the minimum disease incidence and maximum biometrics of rice. The same treatment recorded the minimum amount of amino nitrogen content whereas protein and starch content increased when compared to comparison fungicide and control treatments. Protein content increased up to the 14th day of sampling and then slightly reduced in all the treatments. The minimum protein content was recorded in control at final sampling
