The influence of soil conditions using the 'least-disturbed soil' sample technique on growth of rubber was studied. Tjir 1 seedlings grown on friable clayey soils with good physical properties produced the highest dry matter. The Oxisols (Kuantan Munchong Segamat Malacca and Holyrood series) produced more dry matter than the Ultisols (Serdang Rengam Chat Durian and Harimau series). The Entisols (Linau and Briah series) when drained were average in dry matter productivity. The Entisol associated with a high water-table (Linau under flooded conditions) yielded very poorly. The least productive soil was the Histosol (peat) irrespective of whether it was well-drained or flooded. Soils could be grouped according to texture favourability of soil conditions for growth and fertility. A higher dry matter production was obtained on clayey soils than on sandier soils. The over-riding importance of a good soil physical conditions over that of a high soil fertility status in encouraging dry matter production was demonstrated. Rubber was shown to be tolerant of loose lateritic clayey soil conditions. Rubber was very sensitive to flooded soil conditions and to peat with resultant very low dry matter yields. It also responded positively to fertiliser applications and yielded poorer at lower sub-surface soil horizons.

Abstract

The influence of soil conditions using the 'least-disturbed soil' sample technique on growth of rubber was studied. Tjir 1 seedlings grown on friable clayey soils with good physical properties produced the highest dry matter. The Oxisols (Kuantan Munchong Segamat Malacca and Holyrood series) produced more dry matter than the Ultisols (Serdang Rengam Chat Durian and Harimau series). The Entisols (Linau and Briah series) when drained were average in dry matter productivity. The Entisol associated with a high water-table (Linau under flooded conditions) yielded very poorly. The least productive soil was the Histosol (peat) irrespective of whether it was well-drained or flooded. Soils could be grouped according to texture favourability of soil conditions for growth and fertility. A higher dry matter production was obtained on clayey soils than on sandier soils. The over-riding importance of a good soil physical conditions over that of a high soil fertility status in encouraging dry matter production was demonstrated. Rubber was shown to be tolerant of loose lateritic clayey soil conditions. Rubber was very sensitive to flooded soil conditions and to peat with resultant very low dry matter yields. It also responded positively to fertiliser applications and yielded poorer at lower sub-surface soil horizons.
