The company’s coffee crop for 1998-99 totalled 8079 tonnes, an all time record. The increase over the previous year’s production of 5830 tonnes was 38.58%. The previous highest crop was 6089 tonnes in 1970-71. The company had fixed a target of 8000 tonnes to be realized by the year 2000-01, and this had been achieved two years earlier, thanks to the emphasis laid on the key areas of irrigation, replacement of unproductive coffee bushes, intensive refilling and improved agricultural practices. It is now our endeavour to reach the target of 10000 tonnes in the year 2001-02.
Which of the following would contribute most to making the target of 10,000 tonnes in 2001-02 unrealistic?
