Title : Enhancing maize (Zea mays L.) productivity through soil acidity managment in Chitwan valley soils Material Type: printed text Authors: Bishnu Hari Adhikary ; Bandhu Raj Baral, Author ; Jeeban Shrestha, Author ; Chitra Bahadur Kunwar, Author ; Robinson Adhikary, Author Pagination: 260-265 p. Languages : English (eng) Keywords: Agriculture lime ; green-manuring oil-cakes soil acidification and zea mays Abstract: Acidification of so il is one of the major factors contributing soi l fertility decline in most of the
arable land in the hills and terai of Nepal. It does not only limit the nutri ent availabili ty but
also limit the maize (Zea mays L.) production and plant growth resulting low or reduced crop
y ields if not ameliorated. Soil acidity correction measures need to be employed for increased
maize productivity in the problem so il s. To evaluate the effects of different practices
employed in soi l ac idity correction, experiments were conducted during the years 20 I 0 and
2011 in NMRP, Ram pur on the hybrid maize (Across -9944 x Across- 9942 in) and Across-
9331 variety by us ing eight different treatments (control, agriculture-lime, compost , urea-N,
ammonium sulphate-N, poultry manu·re, ex-situ green- manuring and oil-cakes). The plot size
was 12sq.m . (4 m x 3 m). The experiment was la id-out in a randomized compl ete block
design (RCBD) with three replications. Soil samples were collected befo re crop pl anting and
after harvest for so il pH and nutrient analysis. Growth and yield parameters were recorded
and analysed statistica lly. The results revea led that high ly significant effect of treatments on
the crop yields were observed in both years . Highest grain y ield (6.57 t ha- 1
) in the 1 sr year
when the crop was fertilized by oil-cakes at I 0 t ha- 1 where as in the following year the
highest gra in yie ld (5.37 t ha- 1
) was produced by poultry manures at 10 t ha-1
• Appl ication of
oil-cakes at 1 t ha-1 in the 2"0 year produced only 3.84 t ha- 1 of gra ins . Two years mean grain
yield result indicated a sharp response of treatments on the grain production of maize over the
non-treated crop. The highest grain yie ld (5.2 t ha- 1
) was produced when the crop was
supplied with oil-cakes followed by poultry manures which produced the mean grain yield of
4.49 t ha-1
. Lowest grain yield (1.8 t ha- 1
) was produced by non-treated crop (control
plot).Application of agriculture-lime, compost, oil-cakes and green-manuring help decrease
the soil acidity to some extent. It can be concluded that farmers are suggested to apply organic
sources of fertilization along with agriculture-lime for increased maize productivity.This

Title : Use of Sulphur and Agricultural Lime for Enhanced Maize (Zea mays L.) Productivity in Acid Soils of Rampur, Chitwan Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Babu R. Pandey, Author ; B.R. Baral, Author Publication Date: 2010 General note: In: Proceedings of the 26th National Summer Crops Research Workshop.pp 307-312. Summer crops Research in Nepal.Organized by Nepal Agricultural Research Council (NARC) held at National Maize Research Programme (NMRP), Rampur, Chitwan on 3-5 March, 2010 (19-21 falgoon, 2066). Languages : English (eng) Keywords: Agricultural lime; acid soils; maize productivity; significant effect sulphur levels; Zea mays Abstract: Field experiments were conducted during the winter seasons of the year 2007/08 and 2008/09 on an acid soils of the NMRP research farm. The objective of the study was to identify the appropriate doses of sulphur and agricultural lime on maize crop and their recommendation for its increased productivity. Three levels of sulphur (0, 20 and 40 kg S ha-1) and 4 levels of agricultural lime (0, 2.5, 3.75 and 5 t ha-1) were used in the study. A factorial RCB design with 3 replications was employed in the experiment. The variety used was Deutee and the plot size was 22.5 sq.m (5 m x 4.5 m). The crop was fertilized with 120:60:40 kg ha-1 of N, P2O5 and K2O, and 10 t ha-1 of compost, respectively. The highest grain yield (6.86 t ha-1) was recorded in the 1st year (2007/08) when 5 t ha-1 of agricultural lime and 40 kg of sulphur (S) was applied. In the following year (2008/09), the mean effect of S levels indicated a sharp response at only 20 kg ha-1 which produced an yield of 7.84 t of grains ha-1., whereas the mean effect of lime use revealed only the production of 7.55 t ha-1 of grains in the same year when the crop was supplied with 2.5 t ha-1 of agricultural lime. It is noticed that the response of sulphur and agricultural lime on maize grain production was found to be significant in both of the years. Farmers are suggested to apply at least 20 kg of sulpher along with 2.5 t ha-1 of agricultural lime on maize for increased grain production.

Title : Yield Loss Assessment and Management of Violet Wood Sorrel Weed on Maize Material Type: printed text Authors: Govind K.C., Author Publication Date: 2007 Article on page: 38-41 p Languages : English (eng) Keywords: Chari Amilo, herbicide, Oxalis, violet wood sorrel, Zea mays Abstract: A field experiment was conducted during rainy season of 2003 and 2004 in
farmers' field of Dang district (650 masl) to assess the yield loss caused by
violet wood sorrel (Oxalis corymbosa Dc) for maize (Zea mays) and to work
out effective measure to control this weed. Violet wood sorrel (Chari Amilo)
infestation was observed in maize, ginger, and Toria fields of Dang and
Salyan districts as well as various mid hilly areas of Nepal. The weed once
introduced in uplands, spreads in large scale within few years. Six
treatments, comprising 2,4-D Na salt 2 kg/ha, Glyphosate 2 l/ha, Soil
digging, turning and expose to sun two months prior to maize sowing were
compared with weed free, weed free except Oxalis and weedy check plots.
The presence of violet wood sorrel (VWS) in maize field ranging from 38 to
352.3 per square meter in 2003 and 18.6 to 195.5 per square meter in 2004
one month after intercultural operation does not cause significant effect on
maize grain yield, 4297 to 4694 kg/ha in 2003 and 3751.4 to 4473.6 kg/ha in
2004 respectively. Thus significant loss in maize grain yield was not found
due to higher VWS weed population (352.3 and 195.5/m2) resulted in weedy
check treatment and lower weed population (38 and 18.6/m2) in herbicide
applied treatment. Repeated application of herbicides at 17 and 37 days after
maize sowing (DAMS) both 2,4-D and Glyphosate reduced the weed
population in maize field but could not eradicate as it appears in next year
but the population was significantly low (59.5 and 65.3/m2) in herbicide
applied plots compared to weedy check plot (322.6/m2) at 26 DAMS. It was
revealed that presence of violet wood sorrel weed in maize field does not
affect the grain yield in farmer's practice of weeding i.e. intercultural
operation at 20 to 30 DAMS.Link for e-copy: http://elibrary.narc.gov.np/?r=25

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 : Use of Fertilizers and Lime for Enhancing Productivity of Maize Genotypes in Western Hill of Nepal Material Type: printed text Authors: Adhikary, Bishnu H., Author ; Krishna B. Karki, Author Publication Date: 2007 Article on page: 42-49 p Languages : English (eng) Keywords: Agriculture lime, farmer's practice, yield increase, Zea mays Abstract: Farmers’ field experiment was conducted at Outreach sites in Tanahun and Palpa districts of
Western Nepal with the objectives of evaluating the effects of fertilizers and agricultural
lime on grain production of the local and improved (Manakamana-1) maize varieties during
summer season of year 2003 and 2004. Farmer's practice (without fertilizers) and with
fertilizer 60: 30: 30 kg (N: P2O5: K2O) per hectare with or without agricultural lime (4 t ha-
1), were the treatments in experimental study that was conducted in factorial RCB design
with four farmers as replications. The results revealed that response of fertilizers and
agricultural lime was observed significant plant growth and kernels production including
varieties in both sites of Palpa and Tanahun districts. The highest grain yield of 5.1 t ha-1 was
produced by the local variety when the crop was supplied with 60:30:30 kg N, P2O5 and K2O
ha-1 along with 4 t ha-1 of agricultural lime in Tanahun. Manakamana-1 variety produced the
maximum grain yield (4.45 t ha-1) with the same level of fertilization. The two district mean
grain yield result indicated that the highest grain yield of 3.9 t ha-1 was produced when the
crop was supplied with 60: 30: 30 kg N, P2O5 and K2O ha-1 with agri-lime. Hence it is
suggested that to increase maize productivity in the hills irrespective of the maize variety
application of fertilizers (60: 30: 30) with agricultural lime (4 t ha-1) is needed.Link for e-copy: http://elibrary.narc.gov.np/?r=26
