Abstract

Cashew (Anacardium occidentale Linn) is among the leading export crops in Indonesia. It is also animportant smallholder crop mainly grown in the eastern parts of Indonesia. Its expansion of growing the crop, it is however n ot followed by significant increases in yields, being low ranging of 200 – 350 kg/ha. Many factors believed affect yields achieved, begun from environment, cultivatedvarieties, up to poor management of cashew orchard. As the cashew trees are mostly developed in marginal lands, role of ferti lizer uses may become exeedingly important effort in improving the productivity of the crops. In addition, there are many evidences that the crops adequately managed may give better in yields. However, most farmers do not use fertilizers for the crops or if any, added in very small amounts obviously addressed for annual crops like maize, bean or rice usually planted among the cashew trees. As results, the cashew trees are not able to achieve opti mum yields even though the planting materials used might have high in yield potential. The fertilizers that may be used both in form of organic and inorganic ones. They should be added in such way, so the soils on which the crops are planted be able to grow and develop well, in turn, their yields increase significantly.

Abstract

Cashew growing in Indonesia is mainly addressed to economic reasons rather than soil and waterconservations of some degraded soils. Main producing areas of the crop are Southeast Sulawesi, South Sulawesi, East Java, Cen tral of Java, East Nusa Tenggara and West Nusa Tenggara provinces covering about 500.000 ha or about 90% of Indonesian cashew. In general, mean yields of the crop is much lower than those of other producing countries like India and Vietnam. Many factors believed affect low in yields of the crop. Increasing in composition of damaged cashew trees to those of the health ones may bring about steadily declining production of Indonesian cashew. In turn, meanyields of the crop achieved are low. Rehabilitation programs of cashew orchard at field levels are therefore needed, mainly to the main growing areas of cashew trees. Field actions that might be implemented for the purposes are pruning, thinning and replanting with high yielding varieties or clones of cashew. To accelerate of recovering of cashew trees, other orchard managements like fertilizing and controlling of some im portant pest and diseases of the crop should be accomplished in better ways.

Abstract

The objective was to find out the response of mycorrhizal cashew to the decreasing doses of NPK fertilizer in the green house. Experiment  was carried out in the green house of Cikampek research garden at Indonesian Spices and Industrial Crops Research Institute, and ecofisiology,s laboratory at Indonesian Medicinal and Aromatic Crops Research Institute, Bogor for 6 months.  The research was arranged factorially, in completelly randomized design, with 2 factors, 8 combinations and 4 replications.  The first factor was AMF inoculation : control and 300 spores of AMF/plant, and the second factor consisted of 4 rates of NPK fertilizer : full dose (8 g Urea, 8 g SP-36, and 6 g KCl per pot), 3/4 dose, 1/2 dose, and ¼ dose.  The observation parameters were plant growth parameter, the uptake of N, P, K and chlorophyll content.  The result indicated that AMF inoculation positively effected the growth variable of cashew.  AMF significantly increased leaf dry weight (19,8%) compared to without AMF, besides it also increased the content of chlorophyll a, b and total chlorophyll at low level of NPK (1/4 and ½ doses of NPK).  The uptake of NPK of mycorhizal cashew leaf increased about 43,8%, 53% and 49% compared to without AMF.  The decreasing level of NPK to ½ NPK at mycorrhizal cashew (5 months after planting) resulted good performance of plant growth.
