| Summary: | An increasing demand for pineapple cv. MD2 has led to the intensification of the crop
cultivation. A field study was conducted to determine the effects of different carriers of
Trichoderma formulations on growth performance; concentration and nutrient content
status and inoculant availability in soil. Treatments were applied before planting with T1
(Trichoderma+molasses), T2 (Trichoderma+molasses+compost) and T3 (uninoculated
plant). Chemical fertilizers was applied as recommended by MPIB. Plant (D leaf) and soil
analysis were determined using the D leaf samples at 16, 24 and 64 weeks after planting
(WAP). Combination of Trichoderma with both molasses and compost produced the
highest average total dry mass production of pineapple (1107.85g), followed by
Trichoderma with molasses (1016.04g) and control (975.32g) during final harvesting. Dry
mass of D leaf also showed significant difference of plant treated with Trichoderma (T1 -
22.3g and T2 - 25.7g) with control (15.9g). T2 produced the highest amount of dry mass
production for each plant part compared to T1 and T3. Application of both treatment with
Trichoderma produced highest average plant height with respectively 56cm at 20WAP.
The highest number of leaves and stem diameter were recorded from T1; obtained 35
leaves and 63cm diameter respectively. No significant difference observed in yield
production (fruit fresh weight) and total soluble sugars. T2 produced the highest average
fruit weight and total soluble sugars (2.35kg & 16.53 0brix) followed by T1 (2.24kg &
16.12 0brix ) and T3 (2.04kg & 16.10 0brix). Similar trend was observed in N
concentration of pineapple D leaf and root. T2 recorded the highest N concentration in
both D leaf and root (1.62% & 0.64%) followed by T1 (1.52% & 0.63%) and T3 (1.36%
& 0.54%). The incorporation of Trichoderma with molasses and compost gained more
inoculant population compared to the single-use molasses. Present study indicated that
combination of Trichoderma with molasses and compost produced better growth
performance, enhanced plant nutrient concentration and produced more inoculant
population in soil for pineapple cv. MD2. Therefore, the study suggested that the
combination of both molasses and compost with Trichoderma spp. can be used by
farmers for gaining good quality of pineapple cv. MD2. |
