ESTATE CROPS INFO –

The period of using plastic mulch on white grubs population and productivity of sugar cane at white grubs endemic area was conducted in Banyuputih Village, Situbondo on planting season of 2014/2015. Treatment consisted of 5 plastic mulch period (1) Before raining (SBH), (2) One day after rainfall, 14 mm (1 HSH), (3) Seven days after raining (7 HSH), (4) 14 days after raining (14 HSH), (5) 21 days after raining (21 HSH) and Control (without mulching plastic). Research using Randomized Block Design was repeated 5 times. Parameters observed in white grubs and adult (beetle), percentage of plant damage, productivity of sugar cane and sugar and rainfall data. The results showed that all plastic mulch period treatments significantly reduced white grubs population and crop damage compared with controls. Treatment of plastic mulch period of one and seven days after raining provides a difference in productivity of sugar cane of 83 tons/ha (7.7 tons/ha) and 96 tons/ha (sugar 7.8 tons/ha) above the control and both treatments can be recommended. This research needs to be continued especially to find out the efficiency of using plastic mulch in endemic white grubs area.
