ESTATE CROPS NEWS – Increasing productivity of sugarcane would give a direct impact on increasing farmer income, as well as farmer motivation. Case study in dry land sugarcane plantation at Lambur vilagge, Mrebet district of Purbalingga region was aimed to show the effect of intensive, semi intensive dan non intensive cultivation to economic value of sugar cane.
Result of this study showed that intensive planting cane cultivation of sugarcane by applicating cow manure 5 ton per ha, sufficient irrigation, with overlapping planting system, and old leaves detrashing, as well as implemented extensification aid program, was achieving approximately 150 ton productivity of Bululawang sugarcane variety, with rendement level of 7.16%. This was giving farmer income 32.38 million rups per ha. While semi-intensive cultivation of sugarcane (without cow manure) was yielding 100 ton sugarcane, by the same level of rendement and was giving 16.45 million rups per ha. However, non-intensive sugarcane (without irrigation, without cow manure, end to end planting system) only achieved 45–75 ton sugarcane per ha. The last implementation also showed that the use of an-organic fertilizer without organic ferlizer was not an optimal productivity of dry land sugarcane at this area. Besides, the 45 ton yield of sugarcane would cause detriment of 2.78 million rups per ha. B/C ratio of intensive, semi intensive, non – intensive1 and non-intensive 2 cultivations, were 1,68; 1,44; 1,25; and 0,89 respectively.
To implement the use of organic fertilizer on farmers fields are suggested for group of farmers, where their plantation is closed from sugar manufacture, to have cooperation and collaboration in using organic waste material as “blothong” of the manufacture for fertilizing their farms. Meanwhile for those that are far from the sugar manufacture, are suggested to rear cow and using the cow manure for ferlize their plantation.
