AB  - The increasing importation of starch in Malaysia for poultry 
  and bio-processing industries is a call for concern. The development and released 
  of improved cassava genotype (Sri Pontian) in 2003 by the Malaysian Agricultural 
  Research and Development (MARDI) was a good step to enhance cassava productivity. 
  Sri Pontian was reported to show higher yield than those of Manihot Mardi 92 
  and Sri Medan (the popular table variety). Such claim has not been verify in 
  East Malaysia. This research was carried out to verify the aforementioned claim 
  by comparing selected yields attributes of Manihot Mardi 92, Sri Medan and Sri 
  Pontian at Bintulu, Sarawak, East Malaysia. This study was conducted at experimental 
  field of University Putra Malaysia Bintulu Campus Sarawak from July to December, 
  2011. The experimental design was a randomized complete block with three replications. 
  The three varieties evaluated were: Manihot Mardi 92, Sri Medanand Sri Pontian. 
  These varieties were planted on ridges with three planting methods: Vertical 
  planting (forming 90° angle to the ridges), incline planting (forming 45-60° 
  angle to the ridges) and horizontal planting (forming 180° to the ridges). 
  Variations among the varieties were observed for number of shoots retained per 
  plant, leaf longevity, leaf area index, number of storage roots formation and 
  fresh storage roots yield. Significant interaction effect between variety and 
  planting method was observed for all the variables tested, except for number 
  of shoots retained per plant and number of storage roots per plant. All varieties 
  showed similar number of shoots per plant regardless of planting method except 
  for Sri Pontian which had lowest effect with respect to number of storage roots 
  formation per plant in incline planting. Similarly, leaf longevity in Sri Pontian 
  was the lowest regardless of planting method. Sri Medan showed the greatest 
  leaf area index, number of storage roots formation per plantand fresh storage 
  roots yield. The effect of Manihot Mardi 92 in terms of leaf area index, number 
  of storage roots formation per plantand total storage roots yield in vertical 
  planting was comparable to that of Sri Medan. Sri Pontian had the lowest storage 
  roots yield. This study showed in East Malaysia, Sri Medan was identified as 
  the best genotype with good agronomic attributes. This variety has the potential 
  to increase cassava productivity over a wide range of environmental conditions.
