Title : Effects of Nitrogen Levels on the Plant Growth and Corn Yield of Taro Landraces (Colocasia esculenta Schott) in Acid Soils of Malepatan Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Babu R. Pandey, Author ; Joshi, M., Author Publication Date: 2007 General note: In: IAAS Journal of Plant breeding, 2007, vol (2):12-18. Languages : English (eng) Keywords: Colocasia esculenta; taro landraces; nitrogen levels and corm production. Abstract: Field experiments were conducted at ARS, Malepatan in acid soils (pH 4.36) during the years 2002 and 2003 to evaluate the effects of nitrogen levels on farmers named taro landraces. Split plot design with 3 replications was employed in the experiment. Five levels of nitrogen (0 kg N, 10 t/ha compost, 50 kg N, 100 kg N plus 10 t compost, 150 kg N/ha) and 6 taro landraces (Hattipau, Khari lamo, Thadomukhe,Seto panchamukhe, Khujure rato and Ratomukhe) were taken into study. P and K were applied basally in all plots at the rate of 50 and 100 kg , respectively. Plant growth and corm production parameters were studied. The results showed that plant growth (plant height, petiole production, leaf size)was not significantly affected by the N-levels; however, increased plant height of 70.2 cm was observed when the crop was fertilized only with 10 t /ha of compost. The crop produced 67.21 cm of plant height when it was fertilized with 50 kg urea-N alone. Mean results showed that increased petiole numbers (26.09) were produced by the Khujure rato taro landrace. The two years mean results indicated that the taro crop when fertilized with 10 t of compost along with 100 kg urea-N produced satisfactorily increased cormels (36.27 cormels /plant).In average, increased corm production (52.49 t/ha0 was obtained when the crop was fertilized with 10 t of compost applied along with 100 kg urea-N. Hattipau landrace of taro was found to be high yielding (49.7 t/ha) than other landraces tested.

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.

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 : 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.
