| 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
paper highlights and discuss the results of the soil acidity management practices in detail. |
