Productivity Enhancement Through Nutrient Management in Khampti Lahi and Thailand Lahi Rice.
Introduction:
Rice (Oryza sativa L. 2n =24) is the most important staple food for a large proportion of
world’s population, especially in ASIA. Rice is the second most cultivated cereal after wheat.
It’s provides 20% of the per capita energy, and 13% of the protein consumed worldwide.
Rice is cultivated in about 154 M ha of land across the globe which produces 603 million
tons of grain with the productivity of 2110 kg/ha. It is the grain with second highest world-wide
production after maize in 2010. In Asia where approximately 90% of world’s rice is produced
and consumed (Khus 2004; Zeigler and Barely, 2008), presently rice is grown in 431.94 Lakh ha
areas with the production of about 110.15 million tons in India during 2010-2016.
Rice is the chief food crop in Arunachal Pradesh but having low productivity i.e. yield
below 1,000 kg/ha. That is the reason farmer income is too low. Farmer’s income can be
improved if productivity goes up, it can be possible if we have leverage technology, adopt
precision farming and ensure that farmers get correct and timely crop advisory and market
information. Introduction of promising rice productivity and live hood pattern as well as
enhancement of food security that will reduce poverty level in Namsai areas.
A number of traditional varieties or land races of rice varieties are cultivated by farmers
in Namsai district. The district characteristics are crop growth duration ,yield ,grain quality and
cooking quality of different varieties .The pest and diseases infestations mitigate the growth and
yield of rice crop .The environmental impact causes male sterility that reduce the yield in variety.
Among the traditional varieties khamti lahi is the most popular among the farmers, and recently
introduced variety Thailand lahi is also found promising. Scientific nutrient management is
essential to improve the productivity of these crops. Under these circumstances this project is
proposed with following objectives.
Objectives:
1. To find out the best organic manure suited to rice cultivation under Namsai conditions.
2. To determine response of Thailand Lahi and Khamti Lahi rice varieties to different
organic manures.
Review of Literature:
Aidy et al.(2000) studied the morphological characteristics of the grain, seedlings, tillers,
and adult plants of rice cultivars belonging to japonica, indica groups and suggested that each
group can be differentiated from others by characters such as 50 per cent flowering , leaf,
plant height ,1000 grain weight, grain length and width , phenol test.
Thimmanna et al.(2000) observed thst characters such as leaf length and width,
colour, leaf angle, ligules shape and colour, auricle colour, internodecolour, panicle type,
secondary branching, exertion, awning, seed length andwidth, 100 grains weight and
suggested the usefulness in differenting the parental lines of rice hybrids.
