About 45 % wheat is produced in cotton belt of Pak-Punjab province, so wheat-cotton is the major cropping pattern here. Wheat is often delay planted after cotton, sometimes as late as late December or early January. Yields are, therefore, low. So relay planting of wheat was undertaken jointly with Dir/cotton in Cotton Res. area. Wheat was broadcast sown in standing cotton in November in submerged cotton beds. Relay wheat yielded higher than the TP wheat by a .4t/ha margin. Wheat was followed by 0-til cotton in May on previous cotton crop beds after reshaping to test the possibility of 0-til cotton planting. Germination was good (see pic. below) despite odds proving possibility of cotton planting through 0-til method. Parallel with this cotton was also planted 0-til in cotton-cotton system. Feb/March planting of cotton is gaining ground due to its high yield and rising cotton international prices. March planted 0-til cotton was a success too.
Dir/Cotton is very satisfied with the results despite their initial hesitation (See the pic above) and is a forceful advocate of 0-til planting in cotton now. There are certain hick ups in the way to materialize it, however. Cotton is hill planted manually on beds and relay wheat planting in cotton on beds require machinery. Availability and acceptance of machinery are both a stumbling block in Pakistan situation. So CSISA, Pakistan is working on a two pronged strategy; machinery based and manual. Starting next wheat season we are planning to try 0-til wheat sowing by broadcast after rice to enable 0-til benefits to vast majority of farmers who don’t own 0-til drills. Broadcast DSR is already more popular than drill planted. Handling drills and their calibrations are something farmers don’t relish. So a cheap alternative seems necessary for the interim period until drills availability and use become popular.
