The study was initiated to evaluate the early performance of rambutan (Nephelium lappaceum) vegetative planted on marginal sandy tin-tailing soil. The experiment was carried out for one year in a plot of 4-year-old rambutan cultivar at MARDI Kundang, Rawang, Selangor, Malaysia. Varieties of Mutiara Merah and Mutiara Wangi were used. Data from the plants as a measurement of vegetative growth was recorded. Mutiara Merah proved that it can be well-grown and cultivated on sandy tin-tailing soil. The plant height of Mutiara Merah indicated the highest significant reading. The parameter of canopy width showed the same variety contributed to the highest record. Nevertheless, Mutiara Merah contributed to the highest significant reading on stem diameter and perimeter respectively. Chlorophyll content in leaves of the plant of the same variety recorded the highest SPAD reading. Further field evaluations are needed to determine the relationship of fertilizer level with the different varieties in inducing the growth and yield of rambutan planted in marginal soil.

The study was started to assess the early performance of rambutan yield characteristics planted on marginal sandy tin-tailing soil. The experiment was carried out for one year in a plot of 4-year-old rambutan cultivar at MARDI Kundang, Rawang, Selangor, Malaysia. Varieties of Mutiara Merah were used. Data from the plants as a measurement of yield characteristics was recorded. Mutiara Merah proved that it can be well-yield and cultivated on sandy tin-tailing soil. Mutiara Merah showed that it can be planted and farmed effectively on sandy tin-tailing soil, according to the results of the previous research. It can grow and be useful in boosting rambutan yield. Taking into account the fruit yield parameters as well as yield character components parameters such as fruit weight, seed weight, fruit diameter, flesh thickness, brix, and flesh weight, it can be concluded that rambutan cultivation in marginal tin-tailing soil was found promising for producing higher yields. More field studies are needed to standardize agro-techniques and establish the fertilizer requirements of chemical and organic fertilizers for higher yield in other marginal soils such as peat, bris, and acid sulphate soil, as well as create various value-added products to utilize excess produce.
