Rainfed Lowland Ecologies in Orissa are categorized into
I. Shallow Deep Water Situation ( 0-30 CM)
II. Intermediate deep water situation (0-50 CM)
III. Semi-Deep Water Situation ( 0-100 CM)
IV. Deep Water Situation (>100 CM)
for lateritic soils : • intercropping rice+arhar (upas 120,icpl 87) in 4:1 ratio • rice + ground nut in 4:2 ratio • rice - tomato for alluvial soils: • rice - horsegram / blackgram / chickpea • rice - groundnut / sunflower • rice - mustard • rice - safflower / castor • rice - vegetables • rice - cluster bean • rice - pegion pea • rice - pea/ wheat/ tomato • rice - barley / linseed
• 60:40:40 kg/ha for semi-dwarfs
• 40:20:20 kg/ha for semi-talls
• fym @ 2 t/ha along with 20-40 p2o5 /ha and incubate it
Disease management :
• need based application of hinosan (@ 0.1%) at flowering under drought situation for blast,
• need based application of diathane m 45 (@2.5 g/l) for brown spot.
• One summer plouging and one just before or at the first rain shower to kill the weeds.
• Stale seed bed or combination of stale seed bed + butachlor @ 1.5-2 kg a.i./ha
• For alluvial soil- finger weeders
• For laterite soil- running narrow plough between rows
1. Using chloropyriphos @ 1 kg a.i./ 100 kg seed for termite control
2. Seedling root dipping in chloropyriphos before planting for controlling rice whorl maggot , stem borer etc. (in case of transplanted crop)
3. Row seeding, preferably dibbling, 20cm x 15 cm behind plough or seed-drill
Seeding time first fortnight of june for alluvial soils(sandy soil) & second fortnight of june for laterites(red soil)
• Soil amelioration : by using paper sludge @ 1/4 lime requirement(lr)
( approx. 1500 kg /ha)
• For 90 days duration: vandana, kalinga iii, banaprabha, dhala heera, heera and sneha
prabhat , turanta dhan , ghanteswari , ndr - 97
• For 115 days duration : annada, lalat, ratna, jajati, naveen, luit , kapilee

3. irrigated ecology
In some soil types it is desirable to develop a ‘hard pan’ or impermeable layer to stop deep percolation of water below the root zone of the crop. This hard layer is best achieved by using an implement that actually smears the soil during its normal mode of action. The rotovator is the best implement for this operation. High levels of wheelslip from tractors fitted with cage wheels will also give
1. This system requires ploughing to begin in the center of the field and works out to the edges.
2. It requires some measurement of the field to establish the center point and if done correctly leaves a level field with drainage channels on the edges.
3. This system can be used with all types of ploughs. In very large fields, a number of lands may be ploughed
1. The field is ploughed in runs parallel to each other.
2. It starts at one boundary of the field and ends at the opposite with turns being made on the headlands.
3. This system can only be used for tined implements, rotovators, harrows and reversible ploughs.
4. It is usually the most field efficient system and if equipment is correctly set up and operated should not leave furrows in the field.
