 PART I. SUGARCANE STUBBLE REPLACEMENT ANALYSIS
 Introduction

 Each year sugarcane producers face the problem of deciding which cane
should be allowed to ratoon again or should be removed. If the stubble is
replaced costs.for-land preparation and replanting are incurred. Further-

more, if cane is not successively planted or the land is not used for other

purposes, the cost of one season's lost income while the land is fallow must

be included. On the positive side,once the replanted cane is harvested,

revenues are generally higher due. to increased tonnage yields.

 The returns from ratoon crops are less than those from replanted cane,
but the returns may be realized sooner. Land preparation and replanting costs

are also avoided with ratoon crops. The calculations involved in deter-

mining the most profitable decision for a particular field are tedious. In
addition, the methodology involved in making the decision is rather complex.

The"Sugarcane Stubble Replacement Analysis"is designed to overcome both of
these difficulties.

 Sample Run

 The"Sugarcane Stubble Replacement Analysis"asks users to enter certain

information which is used to calculate expected returns from both ratoon and
replant decisions. The first two questions relate to. cost accountingpractices

and the crop cycle on that field. The next six questions concern the user's

expectations if the stubble is not replaced. The underlined numbers which

appear below are sample entries.
