Of Abstracts. Economic Growth Through Science, Technology and Innovation.Paper presented at the Sixth National Conference on Science and Technology (NAST), organized by Nepal Academy of Science and Technology (NAST) held at Hotel Everest, New Baneswor, Kathmandu, on September 25-27, 2012 (Aswin 9-11, 2069). Languages : English (eng) Keywords: fertilizer and manures; grain yield; maize genotypes significant effect. Abstract: The development of agronomic practices in terms of ‘maize genotypes and nutrient management’ is essential for enhancing maize productivity. In order to identify and evaluate suitable rates of fertilizers (NPK and farmyard manures) to different maize genotypes, field experiments were conducted at Rampur, Chitwan during the winter season of 2009/10 and 2010/011. Five levels of fertilization; (1) Control (zero fertilizer), (2) Farm yard manure (FYM) 10 t ha-1, (3); 60:30:20 N, P2O5 and K2O plus FYM 10 t ha-1; (4) 120: 60: 40 N, P2O5 and K2O plus FYM 10 t ha-1; (5) 180: 90: 60 N, P2O5 and K2O kg ha-1 plus FYM 10 t ha-1 and (6) 120: 60: 40 N, P2O5 and K2O kg ha-1 ) applied to four maize genotypes (Rampur Composite, Manakamana-4, Across9942 / Across 9944 and S99TLYQ-B) in the experiment. The experiment was laidout in a factorial RCB design with three replications. The plot size was 12 sq. m (4 m x 3 m) and the crop was planted in the month of October and harvested in April. The results revealed that most of the growth and yield parameters were found significantly increased with increased level of fertilizers (180:90:60 kg N, P2O5 and K2O plus 10 t of compostr ha-1) in Rampur Composite, Manakamana-4 and Across 9942 / Across 9944 where as these parameters were significantly increased in S99TLYQ-B variety with the fertilization level of 120: 60: 40 N, P2O5 and K2O plus FYM 10 t ha-1. Highest grain yield (6068 kg ha-1) was recorded in the year 2009/010 when fertilized by 180: 90: 60 N, P2O5 and K2O plus FYM 10 t ha-1 irrespective of the genotypes, and 4882 kg of grains produced by Rampur composite variety in this year irrespective of the fertilizer levels. Two years mean yield results revealed that varieties such as Manakamana-4, Rampur composite and Across 9942 / Across 9944 produced highest grain yield (5074 kg, 5195 and 5052 kg grains ha-1, respectively) with N, P2O5 and K2O at 180: 90: 60 kg ha-1 plus FYM 10 t ha-1.This paper discuss and highlights the results of fertilizer and manures application on different maize genotypes in detail.

Title : Soil fertility status of Nepal: Report from laboratory analysis of soil samples of five developmental regions Material Type: printed text Authors: Shree P Vista, Author ; Adhikary, Bishnu H., Author Pagination: 42-52 p. Languages : English (eng) Keywords: Acidic condition, organic matter, phosphorus and potash, soil fertility. Abstract: Soil Management Directorate along with Regional Soil Testing Laboratories in diferent Region under Government of Nepal has the mandate to test soil sample across the country. A report on soil fertility status of Nepal was prepared based on the result obtained from seven soil testing laboratories in the fiscal year 2070/71. In this FY, a total of 1700 soil samples were analyzed to determine the status of soil nitrogen (N), phosphorus (P2O5), potash (K2O), Organic Matter (OM) and pH. The results revealed that majority of the soil samples were found to be acidic (53%). Similarly, OM range from low to medium and majority of the samples have low content of soil nitrogen, phosphorus and potash. While comparing the soil fertility status of five development Regions of Nepal, soil pH was found to be dominated by acidic condition except for Far- Western Developmental Region. The organic matter content of the majority of the sample from Eastern Development and Far-Western Development Region was very low. While the OM content of other Region range from low to medium. The nitrogen results also range from low to medium across all the Regions. The status of phosphorus and potash is low in Eastern Region whereas low to high in other Regions. The paper also explored the average status of soil fertility of 38 districts which were mapped by Soil Management Directorate in coordination with respective District Agriculture Development Office. The status of soil nutrient content is declining throughout the nation but the rate of declining is higher in eastern part of Nepal. In this context the technologies to manage soil fertility status should be disseminated throughout the nation. The Government should facilitate to develop its manpower and appropriate technologies.

Title : Use of Fertilizers and Lime for Enhancing Productivity of Maize Genotypes in Western Hill of Nepal Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Krishna B. Karki, Author Publication Date: 2007 Article on page: 42-49 p Languages : English (eng) Keywords: Agriculture lime, farmer's practice, yield increase, Zea mays Abstract: Farmers’ field experiment was conducted at Outreach sites in Tanahun and Palpa districts of
Western Nepal with the objectives of evaluating the effects of fertilizers and agricultural
lime on grain production of the local and improved (Manakamana-1) maize varieties during
summer season of year 2003 and 2004. Farmer's practice (without fertilizers) and with
fertilizer 60: 30: 30 kg (N: P2O5: K2O) per hectare with or without agricultural lime (4 t ha-
1), were the treatments in experimental study that was conducted in factorial RCB design
with four farmers as replications. The results revealed that response of fertilizers and
agricultural lime was observed significant plant growth and kernels production including
varieties in both sites of Palpa and Tanahun districts. The highest grain yield of 5.1 t ha-1 was
produced by the local variety when the crop was supplied with 60:30:30 kg N, P2O5 and K2O
ha-1 along with 4 t ha-1 of agricultural lime in Tanahun. Manakamana-1 variety produced the
maximum grain yield (4.45 t ha-1) with the same level of fertilization. The two district mean
grain yield result indicated that the highest grain yield of 3.9 t ha-1 was produced when the
crop was supplied with 60: 30: 30 kg N, P2O5 and K2O ha-1 with agri-lime. Hence it is
suggested that to increase maize productivity in the hills irrespective of the maize variety
application of fertilizers (60: 30: 30) with agricultural lime (4 t ha-1) is needed.Link for e-copy: http://elibrary.narc.gov.np/?r=26

Summer crops Research in Nepal.Organized by Nepal Agricultural Research Council (NARC) held at National Maize Research Programme (NMRP), Rampur, Chitwan on 3-5 March, 2010 (19-21 falgoon, 2066). Languages : English (eng) Keywords: Agricultural lime; acid soils; maize productivity; significant effect sulphur levels; Zea mays Abstract: Field experiments were conducted during the winter seasons of the year 2007/08 and 2008/09 on an acid soils of the NMRP research farm. The objective of the study was to identify the appropriate doses of sulphur and agricultural lime on maize crop and their recommendation for its increased productivity. Three levels of sulphur (0, 20 and 40 kg S ha-1) and 4 levels of agricultural lime (0, 2.5, 3.75 and 5 t ha-1) were used in the study. A factorial RCB design with 3 replications was employed in the experiment. The variety used was Deutee and the plot size was 22.5 sq.m (5 m x 4.5 m). The crop was fertilized with 120:60:40 kg ha-1 of N, P2O5 and K2O, and 10 t ha-1 of compost, respectively. The highest grain yield (6.86 t ha-1) was recorded in the 1st year (2007/08) when 5 t ha-1 of agricultural lime and 40 kg of sulphur (S) was applied. In the following year (2008/09), the mean effect of S levels indicated a sharp response at only 20 kg ha-1 which produced an yield of 7.84 t of grains ha-1., whereas the mean effect of lime use revealed only the production of 7.55 t ha-1 of grains in the same year when the crop was supplied with 2.5 t ha-1 of agricultural lime. It is noticed that the response of sulphur and agricultural lime on maize grain production was found to be significant in both of the years. Farmers are suggested to apply at least 20 kg of sulpher along with 2.5 t ha-1 of agricultural lime on maize for increased grain production.
