Title : Nematodes and soil fertility Material Type: printed text Authors: P.R Panta, Author Pagination: 261-272 p. Languages : English (eng) Keywords: Bacteria, bio-indicators of fungi, nematodes, soil fertility, health. Abstract: Nematodes can be used as bio-indicators of soil health because they are ubiquitous and have diverse feeding behaviors. A handful of soil contains 50 different species of nematodes and millions of individual can occupy in 1 sq.m, The nematodes residing in soil that do not feed on higher plants some feed on fungi or bacteria; others are carnivorous or omnivorous. It is common belief that nematodes are pathogenic but most nematodes are non-pathogenic and a rich source of organic carbon in marine, freshwater and terrestrial agricultural practices; they eN hanced microbial activity in soil and play a pivotal role in decomposition of soil organic matter, mineralization of plant nutrients and nutrient cycle Bacterial feeding nematodes have a higher carbon: nitrogen (C: N) ratio and while preying bacteria they take N proportion excessively high than their body structure……………………….

Title : Efficacy of Azolla pinnata in Rice (Oriza sativa L.) production in the Central Region of Nepal Material Type: printed text Authors: B. H. Adhikary, Author ; Bajracharya S, Author ; R Adhikary, Author ; Bhurer, K.P., Author ; S.P Vista, Author Pagination: 273-280 p. Languages : English (eng) Keywords: Bacteria, bio-indicators of fungi, nematodes, soil fertility, health. Abstract: Azollapinnata, a floating water fern widely and wildly and found in both hills and tropical Terai of Nepal, has unique character of fixing di-nitrogen (N2)in association with Anabaena azollae that can be utilized as a nitrogen substitute or sometimes can replace chemical nitrogen required to rice crop. A number of past research evidences prove that Azolla has been found beneficial for increasing rice yields. Most recently, this species of Azolla has been collected from different parts of the country and maintained in the Soil Science Division, NARI, Khumaltar , Lalitpur district and Regional Agriculture Research Station (RARS), Parwanipur, Bara district of Nepal. Field experiments of Azolla on rice were carried-out during the year 2014/15 in Parwanipur, Bara and Khumaltar, Lalitpur with different rice varieties in two different agro-ecological zones to evaluate the effects of Azolla pinnata in rice production…………………….
