Soil salinity is one of the major productions limiting factor
saline soil. In Pakistan about 5.7 m ha have been deteriorated
partially or completely by salinity or sodicity. To alleviate the
adverse effects of salinity stress on plants in salt affected soil,
there are two approaches: one to reclaim these soils by applying
chemical amendments to make it suitable for good crop production
and other is the use of salt tolerant plant species. Tolerance of
crop to salinity varies not only among species but also among the
varieties of the same crop. The book in hand furnishes baseline
information on the subject for the researchers, agriculture
graduates and policy makers and allied stalk holders.
Wheat production in Pakistan can be divided into three distinct
periods: 1947-65, 1966-76 & 1976- todate. Wheat production
increased by 647% from 1948 to 2006 whereas area increased by 210%
in this period. Wheat worth of Rs. 220 b is produced year-1, where
in one percent gain/loss in wheat production would be equal to Rs.
2.20 b. During the last 11 years (1999-2009), production varied
from 18.223 to 23.40 m t with average yield of 2262 to 2585 Kg ha-
1. Wheat production is prime objective in agri. policies;
contributes 13.8% to the value added products in agri.& 3.2% to
the GDP. The wheat in arid zones often suffers a serious moisture
stress throughout its life cycle. Wheat yield improvement in the
rainfed areas would be the basis for eliminating hunger and to cope
with demands of population and indirectly upgrade the
socio-economic status of the farming community. The book in hand
provides baseline information on stability, adaptability and
genetic gain in wheat. It can furnish useful guide line for wheat
breeders, policy makers, agricultural graduates and should be in
every agriculture library.
