Title : Effect of Potassium on Potato Tuber Production in Acid Soils of Malepatan, Pokhara Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Krishna B. Karki, Author Publication Date: 2006 Article on page: 42-48 p Languages : English (eng) Keywords: Basal application, potassium levels, Solanum tuberosum, tuber production and topdressing Abstract: Soils of Pokhara valley, especially Malepatan, are fine textured silt loam, extremely acidic in
nature (3.7-4.0 pH) and are medium in soil potassium content. On-station experiments were
conducted to assess the response of potassium (K2O) and its application methods on potato tuber
yield in an extremely acid soil condition. Six potassium levels (0, 50, 75, 100 kg ha-1 as basal
application, 50 kg basal plus 50 kg top dressed, and 50 kg basal plus 50 kg foliar application)
were tested in the experiment for three consecutive years (2000, 2001 and 2002). A randomized
complete block design (RCBD) with 3 replications was employed. Variety used was MS 42.
Nitrogen (N), phosphorus (P2O5) and compost were applied as basal dose in each plots at the rate
of 100 kg, 50 kg and 20 t ha-1, respectively. Three years mean result on the plant growth
characters revealed that tallest plant height was recorded (33.22 cm) when 50 kg ha-1 potassium
was applied basally and 50 kg ha-1 top-dressed. The trend was quite similar in tillers production
(6.96 branches plant-1) and biomass production (168.66 g plant-1). Maximum of 473.33-g plant-1
of tubers was produced when 100 kg of potassium was applied basal single dose. Highest tuber
yield of 24.75 t ha-1 of tuber were produced when 50 kg potassium was applied basally and 50
kg top- dressed, a total of 100 kg ha-1. Highly significant response of potassium levels on tuber
production was observed in all the years. The results of this investigation suggested that
application of potassium (K2O) at the rate of 50 kg ha-1 basal and 50 kg ha-1 top-dressed in 45
days could increase potato tuber yield satisfactorily in extremely acid soil condition.Link for e-copy: http://elibrary.narc.gov.np/?r=45

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 : Study on optimum potassium requirement in rice under rice-wheat cropping system at Chitwan Valley Material Type: printed text Authors: S Srivastava, Editor ; Khadka, Y.G, Editor ; S Raut, Editor ; Shrestha, R., Editor Pagination: 1-5 p. Languages : English (eng) Keywords: Potassium ; Productivity Sustainable Rice-wheat system Abstract: The field experiments were conducted during the rice seasons of the three years (2064,
2065 and 2066) in Rampur, Chitwan to recommend optimal level of potassium for better
and sustainable rice grain production under Rice-Wheat cropping system. Randomized
complete block design (RCBD) was used with seven treatments of potassium levels (0, 15,
30, 45, 60, 75 and 90 kg K20 ha-l) with four replications. The plot size was laid out 12m2.
The Ram Dhan variety was selected for the study area of Chitwan valley. The highest rice
grain production (524lkg ha-l), plant height growth (104.5 em), number of tillers (267) and
straw weight (7067 kg ha-l) were recorded in treatment six (T6: 100:30:75: N: P205: K20
kg ha-l) in the first year (2064). Statistically, both grain and straw yield were found
significantly higher as compare to treatment two (T2: 100:30:15: N: P205: K20 kg ha-l).
In second year, the highest rice grain (3875kg ha-l) and straw (4376 kg ha-l) yield was
obtained from treatment five (T5: 100:30:60:N: P205: K20 kg ha-l). In three years
research period, the highest rice grain (4304 kg ha-l) was produced by the treatment five
(T5). Similarly, the highest straw yield (5106kg ha-l) was obtained by treatment six (T6).
Three years field experiment reveals 60 kg .K20 ha-l recommendation could be sustainable
rice production under rice wheat cropping system of light textured soil. The experimental
results also indicated a depleting trend of inherent soil potassium due to several factors such
as intensive cultivation, leaching losses ·and imbalance use of potassium containing
fertilizers in the cropping systems.Link for e-copy: http://elibrary.narc.gov.np/?r=924 Study on optimum potassium requirement in rice under rice-wheat cropping system at Chitwan Valley [printed text] / S Srivastava, Editor ; Khadka, Y.G, Editor ; S Raut, Editor ; Shrestha, R., Editor . - [s.d.] . - 1-5 p.
