Determining Comparative Economics of Some New Planting Pattern of Sugarcane
Sugarcane is an important cash crop of Pakistan. it is mainly grown for sugar and jaggary production. It is an important source of income and employment for the farming community. It also forms basis for many important industries like sugar, beverages, chipboard, paper, confectionary etc. and provides raw materials to mainly other industries such as chemicals, plastics, paints, synthetics, fibre, insecticides, detergents, etc.
Sugarcane production in Pakistan has increased over time, however this increase has mainly resulted from an expansion in area, whereas yields have increased only slightly. Area, production and yield over the period of 1947-88 grew at an average annual rate of 3.79%, 4.53 and 0.74 per cent respectively (5). in 1988-89, the area under sugar cane was 877 thousand hectares which increased to 885 thousand hectares in 1992-93 and sugarcane production increased from 36976 thousand tons in 1988-89 to 38059 thousand tons in 1992-93. Thus during the same period cane yield increased from 42.2 tons to 43.0 tons per hectare (1) It shows that despite expansion in production over the years, increase in the productivity per unit of area has been very low in Pakistan.
The average sugarcane yields in Pakistan have remained between 4045 tons per hectare, which are considerably less than those obtained in many other countries. Average yield of sugarcane in the world is around 60 metric tons per hectare, while India and Egypt are obtaining 65 tons and 103 tons per hectare respectively, (2) Thus Egypt with highest cane yield in the world is getting about 140 per cent higher yield than Pakistan. India with almost similar soil and climatic conditions is obtaining about 51 per cent higher cane yield than Pakistan.
Within Pakistan, even there exists a large yield gap between yield obtained by the progressive farmers and that of national average. Moreover, much higher production potential has been exhibited at the research stations.
It has been observed that conventional planting methods and low plant population were responsible for low yields (4).
Most recently some new patterns of planting sugarcane have been developed at research stations which not only facilitate doing some essential operations freely and conveniently, but also help establish appropriate plant population per unit of area and thus increase production. The main objective of these experiments has been to carry out experiments to see the effects of various plantation techniques on yield of sugarcane. A lot of data were available with these research stations which could be put to economic analysis to assess the benefits and costs of alternative planting methods.
The present study is directed to assess and compare gross and net benefits of the use of various sugarcane planting methods and to suggest the most appropriate planting pattern. It can help growers of sugarcane to increase their cane yields at the lowest possible cost.
Materials and Methods
The present study was based on Experimental data of different planting patterns of sugarcane collected from experiments conducted in 1989-91 at Post-Graduate Agricultural Research Station (PARS), University of Agriculture, Faisalabad.
Following planting techniques of sugarcane were compared.
PT1 = 90 cm spaced double row strips.
PT2 = 100 cm spaced 100x100 cm pits.
PT3 = 75 cm spaced 100x100 cm pits.
PT4 = 90 cm spaced 90x90 cm pits.
PT5 = 75 cm spaced 90x90 cm pits.
The data were analysed by using partial budgeting technique described by CIMMYT (1988). Partial budgeting technique is mostly used to compare new technologies with current farmer practices, to judge the possibility of adoption by the farmers. It is simply a part of an enterprise budget or crop rotation or farming systems budget. Basically, it involves selecting out only those costs that vary with the particular planting technique being analysed. …
