Title : Long term effect of organic manure and fertilizer on soil chemical properties Material Type: printed text Authors: SP Vista, Editor ; Thapa, Y.R., Author ; K.N Mishra, Author Publication Date: 2010 Pagination: 369-376 p. Keywords: FYM ; Fertilizer organic matter soil reaction Abstract: A long term (2001-2004) field experiment was conducted on sandy clay loam soil with acidic soil reaction to study the effect of
organic manure, chemical fertilizer and combination of both organic manure and fertilizer on soil chemical properties at South farm
(.Kholitar) of ARS Pakhribas, Dhankuta at an altitude of 1420 mas! under rice wheat cropping system with various treatment
combinations including FYM, chemical fertilizer, combination of FYM and fertilizer both at full and half doses. The soil reaction
was found buffered in the soil treated with organic manure at full dose and the soil turned more acidic when treated with chemical
fertilizer at full dose. Application of both organic manure and fertilizer at full dose showed higher organic matter content in the soil.
The nitrogen content in the surface soil was found high both in organic manure treated soil as well as combination of organic manure
and fertilizer at full dose. Application of full dose of nutrients through organic manure recorded significantly higher phosphorus
content in the surface soil. However, the potassium content in the surface soil was not found consistent throughout the period of
investigation.Link for e-copy: http://elibrary.narc.gov.np/?r=1038 Long term effect of organic manure and fertilizer on soil chemical properties [printed text] / SP Vista, Editor ; Thapa, Y.R., Author ; K.N Mishra, Author . - 2010 . - 369-376 p.

Title : Long-term soil fertility management in rice-wheat cropping pattern of wheat at mid-hill of eastern region (2063/064) Material Type: printed text Authors: SP Vista, Editor ; Thapa, Y.R., Author Publication Date: 2010 Pagination: 410-414 p. Abstract: Wheat is second staple crop grown in Tarai as well as river basin and mid hills ofNepal. A pennanent field experiment was established
since 1997 with three levels o ~ nutrients in seven treatments, two different sources of inorganic and organic manures and one without
external sources of nutrients on a sandy-loam soil. Rice-wheat crops were supplied 80:15:15 and 50:15:15 kg NPK ha-1 respectively, and
nitrogen only considered through organic sources. Rice-wheat crops were planted in the plots of 4m*4m were replicated four times. This
experiment had been conducted at south farm of Agricultural Research Station Pakhribas (ARSP), this experimental plots represent the
mid hills of Eastern Region (ER) where rice-wheat cropping pattern is followed. Deterioration of soil properties due to inadequate
nutrient management and adverse change in climatic parameters are considered. Soil productivity is closely linked with soil organic
matter (SOM) status. Annapurna variety was planted first week of October in both year of 2063 and 2064. The organic manure was
supplied theN fixed on the basis oflaboratory test value but P and K was not adjusted and in case inor3 .. nic sources all NPK adjusted as
levels fixed. During crop period highest temperature 24.15° centigrade was in September, where as minimum temperature 8.46°
centigrade was recorded in November. Total rainfall occur during crop period was 725.6 mm in 69 days. Soil samples were collected
periodically within 10 days after wheat harvest from the 0- to 15-cm soil depth using a tube auger. Nutrients status in case nitrogen
percent 0.04 to 0.27, phosphorus I 0.19 to 65.49 ppm and potassium mnges from 25.37 to 38.25 ppm and soil texture is sandy loam. Grain
yield and other agronomic parameters in 2062/06~ and 2063/064 were better in combination of organic and inorganic sources of
nutrients.Link for e-copy: http://elibrary.narc.gov.np/?r=1045 Long-term soil fertility management in rice-wheat cropping pattern of wheat at mid-hill of eastern region (2063/064) [printed text] / SP Vista, Editor ; Thapa, Y.R., Author . - 2010 . - 410-414 p.
