Effect of Nitrogen on Inbred Maize Seed Production Planted at Varying Densities in the Acidic Soil at Rampur, Chitwan / Adhikary, Bishnu H.
Title : Effect of Nitrogen on Inbred Maize Seed Production Planted at Varying Densities in the Acidic Soil at Rampur, Chitwan Material Type: printed text Authors: Adhikary, Bishnu H., Author Publication Date: 2008 General note: In: Proceedings of the Abstracts. pp 19. Fifth National Conference of Science and Technology organized by Nepal Academy of Science and Technology (NAST) held on 10-12 November, 2008 (Kartik 25-27, 2065) at Kathmandu, Nepal (full paper 10 p). Languages : English (eng) Keywords: Grain and stover yield; maize inbred; nitrogen levels; plant density significant effect. Abstract: Attempts have been made to summarise and highlight research findings on the seed production of maize inbred through the use of different levels of nitrogen to the crop planted at varying densities. Series of experiments on NML-1 inbred were conducted in acidic soil (5.1 pH) during the year 2003 and 2004 at the farmland of NMRP, Rampur to evaluate the effect of nitrogen and plant densities on the grain production of maize inbred. A factorial RCBD with three replications was employed in the experiment for the two consecutive years. Nitrogen at 60, 120 and 180 kg N /ha was applied and plant densities at 55,555; 66,666 and 83,383 plants/ ha were maintained in the experiment. Crop growth and yield parameters were analyzed statistically. The results revealed that crop growth (plant and ear height) was observed to be non-significant by the effect of the crop density; however the effect of density and nitrogen on stover production was observed to be significantly affected. The highest stover yield (7.7 t / ha) was produced by the crop planted at the density of 66,666 plants/ha when the crop was supplied with 180 kg nitrogen /ha. The highest number of kernels per kernel row (24.3 kernels / row) was observed at this level of N and plant densities. The effect of nitrogen and density on thousand grain weight was also found to be significant. Two-years mean result revealed that highest seed yield (2.85 t/ha) was obtained when the crop was supplied with 180 kg nitrogen /ha and plant densities at 66,666 plants ha. Increased seed yield of NML-1 inbred could be obtained with increasing rate of nitrogen application upto the density of 83,383 plants/ ha.

Languages : English (eng) Keywords: rain production; hybrid maize; nitrogen levels; plant densities and significant effect. Abstract: Hybrid maize developed from RML-4 and NML-2 and Deutee, a OPV maize variety were tested for the study of response of 3 levels of nitrogen (60, 120 and 180 kg N ha-1) and 3 plant densities (55,555; 66,666 and 83,333 plants ha-1) in the years 2007/08 and 2008/09 in the acidic soil of NMRP research farm, Rampur, Chitwan. A factorial RCB design with 3 replications was employed in the experiment. The crops were fertilized with basal application of 10 t ha-1 of compost and 60 :40 kg ha-1 of P2O5 and K2O, respectively. Three levels of N were applied in the respective plots, half as basal and the remaining half as topdressing at knee high stage. The crops were planted in September at a spacing of 30 cm x 60 cm, 25 cm x 60 cm and 20 cm x 60 cm, and harvested in Janauary at the full maturity stage. The crops were sown in 18 sq.m. plot. The results showed positive effect of N on the grain production of the both varieties.This paper discuss and highlights the results of N application on Deutee and hybrid maize planted at varying densities.

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.
