hello Sir
Under SRI paddy fields are not flooded but kept moist during vegetative phase. Later only one inch water is maintained.. SRI requires only about half as much water as normally applied in irrigated rice.Over 1, 00, 000 farmers are experimenting with this system worldwide at present.
SRI Paddy Cultivation requires less water, involves less expenditure and gives more yields.
In SRI Paddy Cultivation Less quantity of seeds - 2 kg / acre - is required.
Hence fewer plants per unit area (25 x 25 cm) whereas in mainstream chemical intensive paddy cultivation requires 20 kg seed per acre. (1 acre= apprx 0.4 ha)
In SRI rice crop grows healthy in natural conditions and its root growth is massive. It receives nutrients from deeper layers of the soil.
SRI is initially labour intensive
* Needs 50% more man-days for transplanting and weeding.
* Mobilises labour to work for profit.
* It offers an alternative to the resource poor, who put in their family labour.
* Once the right skills are learnt and implemented, the labour costs will be lesser..
SRI encourages rice plant to grow healthy with
* Large root volume
* Profuse and strong tillers
* Non lodging
* Big panicles
* More and well filled grain panicles and higher grain weight
* Resists insects because it allows rice to absorb soil nutrients naturally
Maximum tillering (30 tillers/plant can be easily achieved; 50 tillers pen plant are quite attainable.) occurs concurrently with panicle initiation. Under excellent management even 100 fertile tillers per plant or even more can be achieved due todue to early transplanting and absence of die back of roots.
