Title : Biochar: Its role in soil management and potentiality in Nepalese Agriculture Material Type: printed text Authors: S.P Vista, Author ; A.G Ghimire, Author ; S.H Peter, Author ; S Shackley, Author ; B. H. Adhikary, Author Pagination: 174-177 p. Languages : English (eng) Keywords: Biochar, degraded and spoiled lands, Nepalese agriculture tremendous soilpotentiality management. Abstract: Biochar, the final product of pyrolysis of biomass, can be used as a soil amendment to increase plant growth, yield, improve water quality, increase soil moisture retention and availability to plants, reduce soil emissions of greenhouse gases (GHGs), reduce leaching of nutrients, reduce soil acidity, and reduce irrigation and fertilizer requirements. These properties of soil are very dependent on the properties of the biochar, and may depend on site specific ecological conditions including soil type, condition (depleted or healthy), temperature, and humidity. Biochar can be used in the reclamation of degraded and spoiled lands (acidic, alkaline, sodic and saline soils)…………………………..

Title : Effect of nitrogen on grain production of Hybrid Maize (RML-4/NML-2) in the acid soil of Rampur, Chitwan Material Type: printed text Authors: B. H. Adhikary, Author ; B.R. Baral, Author ; Shrestha, J., Author Pagination: 71-78 p. Languages : English (eng) Abstract: Hybrid maize (RML-4/NML-2) was evaluated for its grain production by the application of different levels of nitrogen (60, 120 and 180 kg N ha-1) at varying plant densities (55555, 66666 and 83383 plants ha-1) along with 60 kg P2O5 and 40 kg K2O ha-1 in the acidic soil (pH 5.3) of National Maize Research Program, Rampur, Chitwan during the years of 2008/09 and 2009/10. Factorial randomized complete block design (RCBD) with three replications was employed in the experiment. The crop was planted at the plot size of 18 m2 (3.6 × 5 m). The crop was planted in the month of September and harvested in February. The results showed a sharp response of nitrogen application to this crop whereas the effect of density was observed to be insignificant. Two years mean yield results showed that highest grain yield (11.10 t ha-1) was recorded when the crop was supplied with 180 kg nitrogen and with 83383 plants ha-1 followed by the crop supplied with 120 kg N ha-1 and 66,666 plant population (10.69 t ha-1). It is inferred that application of high dose of N (180 kg N ha-1) could help increase hybrid maize grain production in acidic soils.

Title : Effects of Different Levels of Agricultural-Lime on Brinjal (Solanum Melongena L) Production in Acid Soils Material Type: printed text Authors: B. H. Adhikary, Author ; C. Adhikary, Author Pagination: 316-320 p. Languages : English (eng) Keywords: agricultural-lime, brinjal fruit production. soil pH, Solanum melongena Abstract: Field experiment Oil brinjal (Solanum melongena L var. Pokhara Lurki) was conducted in
acid soils (4.13- 4.23 pH) during the years 2001 and 2002 at Malepatan, Pokhara to
evaluate the effects of agricultural-lime Oil the production of brinjal fruits and its effect Oil
soil pH. The experiment was designed in a randomized complete block design (RCBD) with
three replications. The plot size was 12 m2
• The fertilizer and manures were applied at the
rate of 100:75:75 N: PzO$: KzO kg/Ira and 25 tom per hectare of compost. Six levels of
agricultural-lime (0 tllra, 1 t, 2 t, 3 t, 5 t, and 10 tlha) were applied as the treatments in the
experiment. The results revealed that significant (P< 0.05) respollse of agricultural lime
was observed Oil fruit length and number of fruits per plant. The fruit circumference was
significantly (P<O.Ol) increased with tire incl'eased level of lime. The fruit yield production
due to different levels of lime was observed significantly contributed in both the years. The
mean yield results indicated a non-significant yield differences among 3t/lta (12.31 tlha),
5t/lra (12.1 t/ha) and JOt/Ira (13.06 t/lta), Soil test results revealed that mean soil pH value
before lime application was observed to be 4.13 pH, whereas the pH value after lime
application was obtained to be 5.34 pH which was almost 29% increased over that year
before lime application. On the basis of brinjal fruit yield alld quality, 3t/lra agricultural
lime is suggested for acid soil of Malepatan. If someone is interested to increase soil pH
without considering cost of agricultural lime, 51/Ira could be applied without affecting
brinjal yield.Link for e-copy: http://elibrary.narc.gov.np/?r=546 Effects of Different Levels of Agricultural-Lime on Brinjal (Solanum Melongena L) Production in Acid Soils [printed text] / B. H. Adhikary, Author ; C. Adhikary, Author . - [s.d.] . - 316-320 p.

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 : Efficacy of Azolla pinnata in Rice (Oriza sativa L.) production in the Central Region of Nepal Material Type: printed text Authors: B. H. Adhikary, Author ; Bajracharya S, Author ; R Adhikary, Author ; Bhurer, K.P., Author ; S.P Vista, Author Pagination: 273-280 p. Languages : English (eng) Keywords: Bacteria, bio-indicators of fungi, nematodes, soil fertility, health. Abstract: Azollapinnata, a floating water fern widely and wildly and found in both hills and tropical Terai of Nepal, has unique character of fixing di-nitrogen (N2)in association with Anabaena azollae that can be utilized as a nitrogen substitute or sometimes can replace chemical nitrogen required to rice crop. A number of past research evidences prove that Azolla has been found beneficial for increasing rice yields. Most recently, this species of Azolla has been collected from different parts of the country and maintained in the Soil Science Division, NARI, Khumaltar , Lalitpur district and Regional Agriculture Research Station (RARS), Parwanipur, Bara district of Nepal. Field experiments of Azolla on rice were carried-out during the year 2014/15 in Parwanipur, Bara and Khumaltar, Lalitpur with different rice varieties in two different agro-ecological zones to evaluate the effects of Azolla pinnata in rice production…………………….
