Title : Influence of soil ph and initial density of Root Lesion Nematodes (Pratylenchus spp.) on their multiplication in maize Material Type: printed text Authors: Baidya, S., Author Pagination: 78-85 p. Languages : English (eng) Keywords: Inoculation, maize, Pratylenchus penetrans, crenatus, soil pH Abstract: Pratylenchus penetrans and P.crenatus often occur together in the field. The damage potential of P. penetrans to several field crops is well known whereas the damage caused by P. crenatus on the field crops is said to be minor or nonexistent. An experiments was carried out in two different soil pH 5.5 and 6.5 to investigate the influence in the population of P. crenatus (Pc) and P. penetrans (Pp) when inoculated juveniles artificially in the following Pc:Pp ratios: 0:0, 100:00, 75:25, 50:50, 25:75, and 0:100 on maize in growth chamber at 20º C. The experiment was laid down in a RCBD with five treatments having eight replications……………….

Title : Preparation of VDC level land use, soil and land capability maps of Chaumala VDC,Kailali Material Type: printed text Authors: D.R Chalise, Author ; A Joshi, Author ; Chet R.B, Author ; B Twanabasu, Author ; N Rawal, Author ; S Amgai, Author Pagination: 345-357 p. Languages : English (eng) Keywords: Available potassium, land capability, use, soil pH and total nitrogen. Abstract: A research was conducted to characterize soils of different land uses to prepare VDC level land use map, soil and land capability maps in August, 2014 in Chaumala VDC of Kailali district. A total of 87 soil pits from different land uses were studied and soil samples from surface soils (0-20 cm soil depth) were analysed for different physico-chemical . Altogether seven land uses were found in the project VDC viz. agriculture, residential, commercial, industrial, forest, public services and others category with forest covering 66.53% and commercial area covering only 0.12% of total land use soil area. pH ranged from 6.2 (slightly acidic) to 7.8 (moderately alkaline). Total nitrogen ranged from 0.02% (very low) to 0.35% (low), whereas available phosphorus from 36 kg ha-1 (medium) to 751 kg ha-1 (very high). Available potassium was low (81 kg ha-1) to medium (349 kg ha-1). A total of thirteen land capability classes were observed in the project area with IAu/1 covering 26% and IIAu/1R covering only 0.07% of the area.
