Title : Effects of micronutrients on growth and productivity of maize in acidic soil Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Shrestha, J., Author ; B.R. Baral, Author Publication Date: 2010 General note: In: International Research Journal of Applied and Basic Sciences. Vol., 1 (1), 8-15, 2010 Languages : English (eng) Keywords: Combined analysis; correlation; grain yield; significant effect; Zea mays L. Abstract: Micronutrients are trace elements which are needed by the maize crop in small amounts and play an active role in the plant metabolic functions in shortage of which show deficiency symptoms and crop yields are reduced, they are therefore to be added into the soil before crop planting or applied directly to the crop to increase maize productivity. In order to evaluate the effects of micronutrients (B, Zn, Mo, S and Mn) on the grain production of maize (var. Rampur Composite), series of field experiments were conducted during the winter season of three consecutive years (2007 to 2009) in the acidic soil condition (5.1 pH) at National maize Research Programme (NMRP), Rampur. Plant growth and yield parameters were studied. Results of the experiments revealed that the treatments had significant effect on studied parameters. Three years yield data following combined analysis indicated a sharp response of treatments on grain production and was observed to be highly significant, however, the response on the maize grain production among the micronutrient treated plots was observed small (5.43- 5.99 t/ha of grains) except with the crop that lacked sulphur nutrient (4.71 t/ha). The highest grain yield (5.99 t/ha) was recorded with the crop which was supplied with all micronutrients (B, Zn, S, Mn and Mo applied in combination with NPK fertilizers at 120:60 40 kg /ha which produced almost 171 % higher grain yield than those with control plot (2.21 t/ha) and 1.48 t/ha of additional grains over NPK treated crop. It is suggested to apply micronutrients along with recommended dose of fertilizers in the acidic soils of Chitwan.

Title : Enhancing Maize Productivity Through the Use of Manures and Fertilizers on the Grain Yield of Different Maize (Zea mays L.) Genotypes Under Acidic Condition Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Sheshraman Upadhyaya, Author ; Babu R. Pandey, Author ; Janmejaya Gaire, Author ; B.R. 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.
