Baral, Author Publication Date: 2010 General note: In: Proceedings of the 26th National Summer Crops Research Workshop.pp 344-350. 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: Combined  analysis;  maize  genotypes;  manures  and  fertilizers;  quality  protein  zea  mays. Abstract: Four improved maize varieties (Arun 1 EV, Manakamana-4, QPM/Posilo makai-1, and Rampur Composite were tested to study the response of different levels of NPK and manures on the grain production of different maize genotypes during the 2 consecutive years 2007/08 and 2008/09. The experiment was conducted in split plot design with 3 replications in the acidic soils (4.6 pH) of NMRP research farm, Rampur at the plot size of 12 sq.m..Manures and PK fertilizers were applied basally at the time of planting and nitrogen (N) was applied half as basal and the other half as topdressing. The crop was planted in the month of September for both years. Growth and yield parameters were analysed statistically following combined analysis. The results revealed a positive response of manures and fertilizers on the grain production of maize genotypes. Two years mean result indicated that the highest grain yield (7.42 t ha-1) was recorded in Rampur Composite variety when the crop was fertilized by 180:90: 60 kg N, P2O5 and K2O along with 10 t ha-1 of compost followed by Posilo makai-1 at 120:60:40 kg N, P2O5 and K2O plus 10 t ha-1 of compost. Arun 1 EV, an early maturing variety, seemed to be weak in grain production even at high levels of fertilization.
