Title : Effect of phosphorus and potash on intensity of spot blotch disease of wheat Material Type: printed text Authors: Bhandari, D., Author Pagination: 331-336 p. Languages : English (eng) Keywords: AUDPC, Interaction, Phosphorus, Potash, Spot blotch, Wheat Abstract: Spot blotch disease caused by Bipolaris sorokiniana (Sacc.) shoem. is the most serious diseases of wheat ( Triticum aestivum L.) in plain areas of Nepal. Nutrient management palpably influences the intensity of the disease. The experiment was conducted to evaluate the effects of various levels of phosphorus and potash, and their interactions on intensity of spot blotch disease of wheat. The experiment was carried out at National Wheat Research Program , Bhairahawa, Nepal in split-split plot design with three replications for two consecutive years...................

Title : Response of Seedling Tuber Size and Level of Potash on Growth and Yield of Clonal Progeny of True Potato Seed under Chitwan Condition Material Type: printed text Authors: K. Atreya, Author ; A. Srivastava, Author ; Shakya, S.M., Author ; Shrestha, S.M, Author Publication Date: 2012 Article on page: 69-78 p. Languages : English (eng) Keywords: Seedling tuber size, Level of potash, Clonal progeny potato Abstract: A field investigation was carried out during winter season of 2007/08 in the
upland of Horticulture Farm of Institute of the Agriculture and Animal Science,
Rampur, Chitwan, Nepal to evaluate the effect of seedling tuber size and level of
potash on ware potato production of a clonal progeny of hybrid TPS, HPS II/67.
The experiment was laid out in a completely randomized block design having two
factors with sixteen treatment combinations replicated thrice. The treatment
comprised of four seedling tuber size (<5 g, 5-10 g, 10-15 g and >15 g) and four
level of potash (30 kg K2O/ha, 60 kg K2O/ha, 90 kg K2O/ha and 120 kg K2O/ha).
Different sizes of seedling tuber and level of potash significantly affected
emergence, growth, yield and yield attributing characters. Growth parameters
like plant height, number of stem per hill, stem diameter, number of leaves per
plant were found to be influenced significantly due to variation in seedling tuber
size and level of potash. Most of the growth parameters increased with an
increase in seeding tuber size and level of potash. An increase in the level of
potash increases the crop's resistance power against late blight and also helps in
earlier tuber initiation. The highest tuber yield (1.36 kg) per plant was obtained
in treatment combination of >15g seedling tuber size and 120kg K2O/ha.
Increasing the size of seedling tuber and level of potash increases the yield of
different classes of tuber. However, potash is responsible for increasing the
tuber size. The maximum tuber yield was obtained when 10-15 g seedling tuber
was used as a planting material and 120 kg K2O/ha applied. Similarly, the
treatment in combination of 10-15 g seedling tuber size and 120 kg K2O/ha wasfound most effective that gave the highest potato yield (30.03 mt/ha).

Title : Soil fertility status of Nepal: Report from laboratory analysis of soil samples of five developmental regions Material Type: printed text Authors: Shree P Vista, Author ; Adhikary, Bishnu H., Author Pagination: 42-52 p. Languages : English (eng) Keywords: Acidic condition, organic matter, phosphorus and potash, soil fertility. Abstract: Soil Management Directorate along with Regional Soil Testing Laboratories in diferent Region under Government of Nepal has the mandate to test soil sample across the country. A report on soil fertility status of Nepal was prepared based on the result obtained from seven soil testing laboratories in the fiscal year 2070/71. In this FY, a total of 1700 soil samples were analyzed to determine the status of soil nitrogen (N), phosphorus (P2O5), potash (K2O), Organic Matter (OM) and pH. The results revealed that majority of the soil samples were found to be acidic (53%). Similarly, OM range from low to medium and majority of the samples have low content of soil nitrogen, phosphorus and potash. While comparing the soil fertility status of five development Regions of Nepal, soil pH was found to be dominated by acidic condition except for Far- Western Developmental Region. The organic matter content of the majority of the sample from Eastern Development and Far-Western Development Region was very low. While the OM content of other Region range from low to medium. The nitrogen results also range from low to medium across all the Regions. The status of phosphorus and potash is low in Eastern Region whereas low to high in other Regions. The paper also explored the average status of soil fertility of 38 districts which were mapped by Soil Management Directorate in coordination with respective District Agriculture Development Office. The status of soil nutrient content is declining throughout the nation but the rate of declining is higher in eastern part of Nepal. In this context the technologies to manage soil fertility status should be disseminated throughout the nation. The Government should facilitate to develop its manpower and appropriate technologies.

Title : Effect of Nitrogen and Potassium Fertilizers on Yield, Storability and Processing Qualities of Potato for the Chips Material Type: printed text Authors: J.P. Gautam, Author ; M.D Sharma, Author ; B.B Khatri, Author ; Thapa, R.B., Author ; K Shrestha, Author ; D.Chaudhary, Author Pagination: 100-112 p. Languages : English (eng) Keywords: Potato, nitrogen, potash, processing qualities for chips and yield. Abstract: Field and storage experiments were conducted to find out the main effects and interactions between
different levels of nitrogen and potassium fertilizers on total yield, yield of different size grade,
storability and better processing quality for chips of potato variety Kufri Jyoti at Hattiban farm
Khumaltar and storage house of Nationai Potato Research Program (NPRP) Khumaltar and at
Balaju cold store, respectively. After harvesting and curing of potato, 5 kg of tubers weight each
tuber more than 60 gram weight were used for the storage and processing qualitY determination.
The storage experiments were conducted in CRD design with 3 replications. Plastic racks and net
bags were used for storage of potato in dark room and cold storage house, respectively. Potato was
stored for 90 days in dark room and 120 days in cold house. Laboratory analyses were carried out
at National Academy of Science and Technology (NAS1) at Lalitpur before and after storage of
potato in ordinary conditions and before immediately after removing from cold store and 15 days
after re-conditioned. Observations were recorded on yield, storage losses, sprouting, chips quality
parameters like specific gravity (SG), dry matter (DM) and reducing sugar (RS). The storage loss
and sprouting percentage was recorded at 15 days intervals of dark sore potatoes and before
storage, immediately after removing from cold and 15 days after reconditioned of cold store
potatoes. The results showed a significant effoct of N and K20 and there interaction on yield,
sprouting, weight loss percentage and quality parameters. Based on the yield and quality
parameters the combination of 150:100:60 kg N: P20 5: K20 along with 20 tons compost I ha is
found suitable for storage and production of processing chips quality potato at Lalitpur and
