EFFECT OF NITROGEN DOSE ON GROWTH, DEVELOPMENT, PRODUCTIVITY AND NUTRIENT USE EFFICIENCY IN RICE (ORYZA SATIVA L.) – A REVIEWPRAVAMANJARI GIRI, NIROJ KUMAR JENA, BRAJKISHOR PRAJAPATI, KAMALAKANTA BEHERA, AMITA RANI PATRA AND SWAGATIKA SAHUAbstract Rice is the staple food crop in most of the developing nations. Dry weight of the plant is primarily derived from nitrogenous compounds, which account for about 10% of their total weight. A component of protein, nucleic acid of nucleoproteins, chlorophyll pigment, hormones that regulate metabolism, and a respiratory-energy carrier. This nutrient is crucial for rice production and the building block of cell metabolism. Several workers have reported beneficial effect of applied nitrogen on rice (Kadiyala et al., 2012; Saha et al., 2017; Kumar et al., 2018; Jyothi et al., 2019). Consequently, different nitrogen levels affect rice growth and yield in profound ways. This review paper is an attempt to provide a brief summary of the work done. In this document, researchers discuss the effects of nitrogen dose on rice growth, development, productivity, and nutrient use efficiency. |
