Title : Effects of nitrogen levels and plant densities on the grain production of Maize (Zea mays var. Deutee) at the acid soils of Rampur, Chitwan Material Type: printed text Authors: B. H. Adhikary, Author ; B.R Pandey, Author Pagination: 73-77 p. Languages : English (eng) Keywords: Zea mays, nitrogen levels, plant densities Abstract: Requirement of nitrogen by maize crop depends on the plant population. The quantity of fertilizer- N applied to the maize crop determines the yield increase or decrease and hence, profitability of the crop. To evaluate the effects of nitrogen levels (60, 90 and 120 kg N/ha) on the maize planted at varying densities (55,555; 66,666 and 83,383 plants/ha), an experiment was carried out for two consecutive years (2006 and 2007) in the farmland of National Maize Research Program, Rampur in a RCB design with three replications. A constant dose of manures and fertilizers at 10 tons of compost and 40: 30 kg/ha of P2O5 and K2O was applied basally in all the experimental plots………………..

Title : Growth and Production of Pineapple (Ananas Comosus L. Merr.) as Affected by Manure and Fertilizer Levels Material Type: printed text Authors: B. H. Adhikary, Author ; C. Adhikary, Author ; S. P. Dahal, Author ; D. B. Ranabhat, Author ; M. Ghale, Author Pagination: 75-79 p. Languages : English (eng) Keywords: Ananas comosus, manure and fertilizer levels, fruit size Abstract: An experimellt on pineapple (Ananas comosus L Merr. ) was conducted at ARS, Malepatan in
acid soil condition ( 4.6-4.8 pH) during the years 1999 to 2003 to evaluate the response of
manure and fertilizers on the plant growth and pineapple production . The experiment was
laid out in a randomized complete block design and was replicated three times. Eigl!t different
levels of fertilizer (NPK) and compost were applied to evaluate their effects on the pineapple
production The results revealed that the manure and fertilizer levels influenced the growth
characters (plant height, leaf, crown and sucker numbers). Maximum suckers ( 1.69 /plant)
were produced wben the crop was supplied with 600: 400: 600 kg per hectare N, P20 5 and
K20 plus 20 ton per hectare of compost. Ma:'Cimum fruit length (10.59 em) and fruit
circumference (29.02 em) were observed at this level of manure and fertilizer application.
Maximum biomass (2.58 kg /plant) and fruit weight (513.33 g per plant) were produced when
the crop was fertilized with 20 ton per hectare of compost plus 600: 400: 600 kg N, P20 5, and
K20 per hectare and were found highly significantly different to other levels of fertilizer
application. The significant response of manure and fertilizers was observed on fruit weight
of pineapple. The minimum fruit weight of 5. 74 tlha which is equivalent toRs. 57,400 /ha, was
observed with the non-treated control crop, whereas the maximum fruit yieliof 11.41 t /ha
which is equivalent to Rs. 1,14, 100.0/ha (gross rerum) was obse1ved when the crop was
supplied with 20 ton per hectare of compost plus 600: 400: 600 kg N. P20 5 and K20 per
hectare where the cost of fertilizer and compost was calculated to be Rs. 75,538.0 /Ita and the
net retum was observed to be Rs 38,562.0 /ha, which was found to be higher than the nontreated
crop suggesting that fertilizer application alone at 200: 100: 200 kg N, P205 and
K20 per hectare could give the highest net- retum of Rs. 75,149.0 per hectare in acid soil
condition of Malepatan.Link for e-copy: http://elibrary.narc.gov.np/?r=466 Growth and Production of Pineapple (Ananas Comosus L. Merr.) as Affected by Manure and Fertilizer Levels [printed text] / B.

[article]
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 : Soil Physico-Bio-Chemical Properties under Poplar+ Indian Mustard Inter Cropping System Material Type: printed text Authors: Tara bahadur Ghimire, Author ; Om Prakash Singh Bana, Author Publication Date: 2015 Article on page: 14-20p. Languages : English (eng) Keywords: Fertility levels, pH. available Abstract: A field experiment was conducted during the winter seasons of 2008-10 at Agroforestry Research Centre, Pantnagar, India with aim to examine the effect of different levels of recommended Nitrogen (N): Phosphorus (P): Potassium (K) (NPK) on soil physico-bio-chemical properties under varying poplar tree densities with mustard introcropping. Lower soil bulk density was recorded under 1000 trees/ha density compared to sole crop in both the year. Soil bulk density (BD) decreased underneath trees. However, soil pH, available N and K were not influenced by tree density in both the years. Electrical conductivity (EC) and soil organic carbon (SOC) increased underneath trees of either tree density compared to sole crop in both the years. Significantly (P<0.05) higher available P was recorded under 1000 trees/ha density compared to 250 and 500 trees/ha densities including sole crop in 2008-09. Similarly, soil microbial biomass carbon (SMBC) increased with increasing the tree density and significantly (P<0.01) higher value was recorded under 1000 trees/ha density compared to sole crop and sparse density both the years except 2009-10, where 500 and 1000 trees/ha densities remain statistically at par. On the other hand, dehydrogenase activity (DA) was maximum under 500 trees/ha density compared to sole crop and 1000 trees/ha density in both the years. Among the fertility levels, the maximum SOC and available N were recorded with 75% compared to 50, 100 and 125% of recommended NPK in 2008-09, except available N with 100% of recommended NPK. But, available P was more with 100% of recommended NPK in 2008-09. Similarly, maximum SMBC were recorded with 75 % compared to higher doses of recommended NPK in both the years. Similarly, BD, EC, SOC, available N, P and K were recorded maximum and soil pH minimum in 0-15 cm soil layers compared deeper layers.
