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.

Enhancing maize productivity through the use of split application of phosphorus and potassium in the acid soils of Rampur, Chitawan / Adhikary, Bishnu H.
Title : Enhancing maize productivity through the use of split application of phosphorus and potassium in the acid soils of Rampur, Chitawan Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Babu R. Pandey, Author Publication Date: 2009 General note: In: IAAS Journal 2009, 30:57-62. Languages : English (eng) Keywords: Crop growth and yield parameters; phosphorus potassium application methods; significant effect; increment Zea mays. Abstract: Phosphorus (P) and potassium (K) are the major food elements for the crop growth and grain production of maize (Zea mays L.).Their response to crop production could vary with their application method and times. Split application of P and K increases the efficacy of the given nutrients and thus increased grain yield could be expected in acid soil condition. To evaluate the effects of methods of P and K application , series of experiments were conducted on maize for 3 consecutive years (2005, 2006 and 2007) in the acidic soils ( 4.77 – 5.09 pH) in the farmland of NMRP, Rampur. The experiments were conducted in RCB design with 3 replications in the plot size
of 12 sq.m. The crop was planted in the month of September and harvested in February. The crop growth and production parameters were studied and analyzed statistically. The results revealed that ear height and kernel rows were found statistically affected in the year 2005 and 2006. Similarly, ear length and kernel numbers were affected significantly in the year 2007. Thousand grain weight was also found significantly affected in all years. The highest 1000 grain weight of 457.66 g was recorded in the year 2007 when the crop was supplied with 40 kg P2O5 (half basal and half topdress) and 30 kg K2O (half basal and half top-dress) along with 10 t of compost and 100 kg /ha of nitrogen. Significant effect of treatments was also observed in straw production during the years 2005 and 2006. The highest straw yield (6.33 t /ha) was recorded in the year 2005 when the crop was fertilized by split application of P and basal dose of 30 kg K2O /ha along with 10 t /ha of compost and 100 kg N. The effects of treatments were observed highly significant on the grain production in all years. Three years mean result revealed that highest grain yield (6.16 t /ha) was recorded when the crop was fertilized by 10 t compost plus 100 kg N applied along with 40 kg P2O5 and 30 kg K2O which were applied half as basal and the other half as topdressing, respectively. The highest yield increment (205.5 %) over the control plot was recorded at this level of fertilization and method of P and K application. Farmers are suggested to apply P and K fertilizers half as basal dressing and the other half as topdress in acid soil condition of Chitwan.Enhancing maize productivity through the use of split application of phosphorus and potassium in the acid soils of Rampur, Chitawan [printed text] / Adhikary, Bishnu H., Author ; Babu R.

Title : Enhancing Maize Productivity Through the Use of Split Application of Nitrogen and Irrigation at Critical Stages in Sandy Soils of Rampur, Chitwan. Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Krishna B. Karki, Author Publication Date: 2008 General note: In: IAAS Plant Breeding Journal, 2008, vol 3:37-42. Languages : English (eng) Keywords: Basal and split application, critical stages, irrigation, topdressing, nitrogen use efficiency zea mays. Abstract: Split application of Fertilizer-N and subsequent irrigation on maize field at critical stages could help increase urea-N use efficiency in sandy soils of Chitwan and thus crop productivity increased. To evaluate the effects of split application of urea-N and irrigation at critical stages of crop growth, an experiment was conducted in the acidic sandy soils of NMRP farmland during the year 2005. Ten t/ha of compost and 60 :40 kg P2O5 and K2O, respectively, were applied basally in all the experimental plots. Some plots received only 50 ky Fertilizer-N and in some 100 kg/ha, which were applied either basally or splitted 2 or 3 times and crop was irrigated 1 or 2 times at the critical stages of crop growth and some crops were not irrigated. Crop was planted at the plot size of 12 sq.m in February and harvested in June. Variety used in the experiment was Arun-4. Crop growth and yield parameters were taken into study and analysed statistically. The crop growth parameters such as plant height, stem girth, straw yield,leaf numbers and number of nodes per plant were observed to be significantly affected by the treatments. Similarly, their effects on test weight (100 grains wt.) and grain yield were also found significantly affected. The highest test wt (341.33 g) was recorded when the crop was supplied with 100 kg N which was applied half as basal and half as topdressing at knee-high stage, followed by 2 irrigations, one at topdressing time and anotherin tasseling stage.Maximum grain yield(4.04 t/ha) was recorded at this level of N application and frequencies of irrigation which produced approximately 134 % higher grain yields as compared to that of non-treated crop followed by 3 split application of fertilizer-N (half basal, ¼ at knee high stage and ¼ at tasseling stage) provided with 2 irrigation, one at 1st topdressing and 2nd in 2nd topdressing time (3.86t/ha0. It is concluded that 3 split application of fertilizer-N with 2 subsequent irrigation at critical stages could help increase the urea-N efficiency and increase the crop productivity of winter maize in sandy soil condition of Chitwan.
