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.

Title : Fertilizer use and maize genotype Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Babu R. Pandey, Author ; Khadka, Y.G, Author General note: In: IAAS Pl.Breeding J.(5): 34-41 Languages : English (eng) Keywords: Acid soil; crop growth and yield; Fertilizer nutrients; maize genotypes significant effect. Abstract: Fertilizers can help produce double or even triple crop yields. By applying the correct amounts of fertilizer nutrients, crop growth and yields are increased. The response of fertilizer nutrients to maize differs from variety to variety (genotypes) and soil fertility status of the area. To evaluate the effects of fertilizer nutrients on the maize genotypes, experiments were conducted in the farmland of NMRP, Rampur during the 3 consecutive years (2005 to 2007). Arun-4, Population -44 C10 (Shitala) , Uphar and ZM 621 (recently released in the name Deutee) were the varieties and six levels of fertilizer and manures were taken for the study. The results showed significant effects of fertilizer nutrients on the crop yield. The three years mean results revealed that highest grain yield of 6.42 t/ha was produced by the Uphar variety when the crop was supplied with 150 : 80 : 60 kg of N, P2O5 and K2O /ha which showed the highest yield increment of 167.5 % over Deutee variety at zero level of manures and fertilizer nutrients. This paper discuss and highlights the response of fertilizers and manures on crop growth characters and yield of different maize genotypes.

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.
