Abstract

A pot culture experiment entitled “soil properties of medium land rice (Oryza sativa L.) in inorganic nitrogenous fertilizers on fym combination in yield.” was conducted at Institute of Agricultural Sciences farm of Siksha ‘O’ Anusandhan (Deemed to be University), Bhubaneswar Odisha on sandy loam soil during kharif 2018-2019. The experiment was planned in a Randomized Block Design with three replications and comprised eight treatment such as T1-Control, T2- 50% Recommended dose of fertilizer (RDF),T3-50% RDF + 5t FYM per ha-1, T4-75% RDF, T5-75% RDF + 5t FYM per ha-1, T6- 100%RDF ( NPK 80:40:40), T7-100% RDF + 5t FYM per ha1and T8-150% RDF. Similar inclination were observed on yields of grain, straw and values of different growth parameters at different level of nitrogen and their combination with 5t FYM per ha-1 but at 150 % RDF level, the values of different parameters including grain and straw yield were significantly low as compared to the treatment that received 100% RDF + 5t FYM per ha-1. Grain and straw analysis recorded higher N, P, K content by use of 100% RDF + 5t FYM per ha-1 as compared with 100% and 150% RDF alone. physio-chemical conditions of soil like bulk density, porosity, organic carbon, available macro nutrients (N, P,K) were improved with the joint application of 100% RDF as inorganic source with 5t FYM per ha-1as organic source. In this present study it can be resolved that in Odisha soil (sandy loam) joint application of 100 % mineral nitrogen and 5t FYM per ha-1 enhanced availability of macro nutrients, better physical environment and produced significantly low yields with application of 150% RDF as compared to treatment combinations with inorganic fertilizer and FYM and almost equal yield with the recommended dose of nitrogen (100% RDF) only in mineral form.

Summary

Introduction

Area wise India occupies first position for greater than 70% of the population of the (44.50 million ha) and production wise it is second world. In India rice is the most important staple 102.75 million tonnes as compared to China but it food, contributing 45% to the total food grain has very low productivity i.e. 2.20 tones haproduction. 67 billion by total area under food grain occupies 69% and 63%. Rice is cultivated in 4.18 million ha and the anual production is 7.58 million tonnes with average yield of 1815 kg ha-1 in Odisha. Nitrogen (N) is one of the main factors affecting rice yield and low nitrogen recovery by the crop under such problematic soils call for a sustainable approach of managing nitrogen for increasing the yield as well as improving its use efficiency. Rice plants depends upon the organic pool of the soil for its nitrogen but the organic pool contains very low amount of nitrogen.[1-7]
