Pineapple residue in Malaysia is usually burnt. The need for sustainable agriculture development coupled with the recent haze problem in Southeast Asia has led a the proposal for zero burning. A study was conducted at Simpang Renggam Pineapple Estate Johor to quantify P and K uptake in pineapple parts and to also compare the efficiency of P and K uptake for burnt and unburnt practices. At maturity plants were sampled from each treatment and partitioned into roots stem leaves fruit peduncle and crown their dry weight and their P and K concentrations determined. Irrespective of the treatment difference p uptake was the highest in the fruit followed by the leaves stem crown peduncle and roots. The order for K was fruit leaves stem peduncle crown and roots. Between 66 - 58 of the total P and K taken up is recycled while the rest 42 - 34 is lost through harvest. Except in roots addition of ash for burnt practice fertilized condition did not significantly increase P and K uptake. For the burnt practice unfertilized condition K uptake in the root was significantly improved. Major difference in P efficiency for burnt 51.60 and unburnt 53.21 practices under fertilized condition was not observed. Burning seems to be essential for reducing cost production as less tillage operation is required and diseases and pests are controlled.

Abstract

Pineapple residue in Malaysia is usually burnt. The need for sustainable agriculture development coupled with the recent haze problem in Southeast Asia has led a the proposal for zero burning. A study was conducted at Simpang Renggam Pineapple Estate Johor to quantify P and K uptake in pineapple parts and to also compare the efficiency of P and K uptake for burnt and unburnt practices. At maturity plants were sampled from each treatment and partitioned into roots stem leaves fruit peduncle and crown their dry weight and their P and K concentrations determined. Irrespective of the treatment difference p uptake was the highest in the fruit followed by the leaves stem crown peduncle and roots. The order for K was fruit leaves stem peduncle crown and roots. Between 66 - 58 of the total P and K taken up is recycled while the rest 42 - 34 is lost through harvest. Except in roots addition of ash for burnt practice fertilized condition did not significantly increase P and K uptake. For the burnt practice unfertilized condition K uptake in the root was significantly improved. Major difference in P efficiency for burnt 51.60 and unburnt 53.21 practices under fertilized condition was not observed. Burning seems to be essential for reducing cost production as less tillage operation is required and diseases and pests are controlled.
