Crop Planning For Aberrant Weather

Crop production in dryland suffers from in stability due to aberrant weather condition from time to time. Delayed monsoon results in non sowing of traditional kharif crops which accounts for nearly 25 to 30% of the total area under crops. So also early withdrawal of monsoon interferes sowing of Rabi a crop which is main constraint of crop production in the region. Similarly, breaks in monsoon also after crop production adversely year 1972 was the lowest rainfall year which resulted in total failure of both Kharif and rabi crops under dry lands.
Mid - Season correction: Crop planning under aberrant weather condition in dry land.

Sr.No.

 Nature of rainfall

Crops to be grown

1.

Delayed on set of Monsoon

 

2.

Rains during July & sowing of kharif crops by end of July or early August.

Setaria (Arjun) Red gram (No. 148) Sunflower (EC 68414), caster () Horse gram (Mans, Sinha)

3.

Rains during August & Sowing up to end of August

Red gram (No. 148) Sunflower (EC 68414) Caster (Aruna)

4.

Rains during late August &
sowing up to Early Sept.

Castor (Aruna). Jowar for fodder

5.

Good onset of monsoon

Sowing of all kharif crops
Common situation usually one or
two dry spells are noticed

6.

If dry spell exceeds tow weeks

Corrective measures
a) Control of plant population
b) Checking weed growth
c) Increasing interculturing
serious situation in drought
prone area

7.

Early withdrawal of monsoon

a) Reducing of plant population from lakh to 50 thousand as in case of rabi Jowar in 35  -1 before grand growth.
b) Use of surface mulch
c) Protective irrigation 30 - 45 days drought.
d) Increase frequently of inter culturing
e) Stripping of leaves

8.

Extended monsoon

It is rarely experienced
a) Sowing of grown and wheat instead of rabi sorghum.
b) Double cropping would be possible in medium deep soils.
c) Postponement of sowing of rabi crops.
