Title : Agro-morphological characterization fo promising lines of rice for mid-hill conditions of Nepal Material Type: printed text Authors: Jwala Bajracharya ; Pratima Pandey, Author ; Dev Bahadur Gurung, Author Pagination: 142-148 p. Languages : English (eng) Keywords: Oryza sativa L. ; genetic variability descriptors purity Abstract: Four promising varieties ofrice (Oryza sativa L.) included in FFT and CVT for bill condition
of Nepal were studied for their agro-morphological characterization and preparation of
descriptors using qualitative and quantitative agro -morphological traits. The experiment was
conducted in Khumaltar, Lalitpur, Nepal , us ing a randomized block design with three
replicates in agricultural season in 2010/ 11 and 20 11 / 12. Genetic vari ation was observed
among the qualitative and quantitative characters evaluated and sign ificant variations at the
least (p < 0.05) were observed for 15 of the 20 analysed quantitative traits. Genetic variance
among the lines was observed hi gher than the envirorunental variance, which ensured the
predominance of the genetic components in the differences observed among the rice
promising lines. Leaf measurement and its orientation, culm strength, panicle exertion length,
panicle type, panicle sterility and biomass related traits were found important distinguishing
traits of these rice varieties. Based on the observed variab ility the descriptors of these
promising varieties were prepared, which is hoped to be of great importance for breeding
programs and maintaining the genetic purityLink for e-copy: http://elibrary.narc.gov.np/?r=879 Agro-morphological characterization fo promising lines of rice for mid-hill conditions of Nepal [printed text] / Jwala Bajracharya ; Pratima Pandey, Author ; Dev Bahadur Gurung, Author . - [s.d.] . - 142-148 p.

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 : Management Study on Seed Potato Production Using Two Alternative Planting Materials under Greenhouse Condition Material Type: printed text Authors: Khatri, B.B., Author ; Z. N. Ganga, Author Publication Date: 1997 Article on page: 16-42 p. Languages : English (eng) Keywords: Degeneration, physiological age , potato, Solanum tuberosum L. Abstract: Z.N. GANGA Benguet State University, La Trinidad, Philippines ABSTRACT This study was conducted in response to the costly and often unavailable seed tubers for growing potatoes. Microtubers and minitubers were used as alternative planting materials of varieties `Granola' and `Monta��'. Results showed that the tuberlet size significantly affected plant height and canopy cover. Larger the tubers planted, the higher the percentage emergence and more number of main stems per plant counted. The number and weight of tuberlets produced were also highly dependent on the size of the micro- and minitubers planted. The bigger the tubers planted, the larger were the tuberlets produced. Higher number of tuberlets were obtained from closer spacings. Planting small tubers generally resulted in higher multiplication ratio of smaller tuberlets, but required careful management. Findings indicate that the minitubers rather than microtubers should be provided to the farmers as the basic planting material at least where the farmers need clean seed stock and cannot afford proper management of delicate materials. Tuberlet production under greenhouse condition is particularly more suitable and important as the planting materials than the microtubers and stem cuttings which are provided directly to the farmers. Minitubers produced may thus reduce the risk of poor crop establishment and favors better crop stand in the farmers' field. .
