| Abstract: | Rice, the most important cereal and staple
carbohydrate source of Asia is cultivated in
diverse ecological conditions and many such agro-ecosystems are fragile and critically
endangered. Some such systems are very special in terms of their ecological
singularity and subsistence value and their conservation would invariably add
to availability of food and protection of genetic diversity. The present study
is an investigation in to a very unique rice farming system in Kerala state of India
in which rice is cultivated in the first crop season in saline wetlands that
are subjected to regular tidal action, taking advantage of the heavy South west
monsoon which results in flushing out the salt content from the farmland. In
Central Kerala the system is known as pokkali
and in North Kerala as kaipad. Kaipad system of
rice farming has been studied presently, based on specialities of the area,
soil and water conditions and the varieties used. The study showed that soil
salinity of the area in summer varied from 10.9 mmhos/cm to 19.9 mmhos/cm and
water salinity in summer varied
from 35.9 mmhos/cm to 49.9 mmhos/cm and in the month of July in the middle of
the South west monsoon it varied from 1.6 mmhos/cm to 4.7 mmhos/cm. Soil pH during April ranged from 4.9 to 6.6.
Water pH ranged between 6.71 and 7.45 in April and in July
it ranged from 6.15 to 6.71. Availability of NPK in the soil ranged as follows
in April: N: 1.12% to 2.0%; P: 7.2 kg/ha to 34.2 kg/ha; K: 480 kg/ha. The major
rice varieties cultivated in the area are the native cultivars Kuthiru, Orkazhama,
Kuttusan, Orthadiyan and Chovverian among which Kuthiru
is the most popular and the best performing. |
