fertiliser MANAGEMENT FOR IMMATURE OIL PALM planted ON AN INLAND TERRACED SOIL 314 by: ZIN Z ZAKARIA; KHAIRUMAN, H and TARMIZI, A M W MPOB TT No. 307 MPOB information SERIES ISSN 1511-7871 JUNE 2006 ith the current labour shortage, to curtail the rounds of fertiliser application, subsoil attitude ( hide) has attracted much interest, especi tout ensembley in remote areas and on undulating terrain. This is mainly due to the whimsey that burying the fertilizer is as effective as bare it with cut back run-off losses. Foster and Goh (1975) recommended that fertilizers be broadcasted to maximize their contact with the feeding roots. In Sabah, Soon and Hoong (2002) plunge that burying fertilizer offered no advantage oer broadcasting even for immature to young ribbons. In fact, Broeshart (1959) found that burying fertilizer at 10 cm depth reduced uptake considerably. In view of the different responses obtained and continued interest of the i ndustry in subsoil placement of fertilizers, a test was conducted by MPOB to compare various compound and at erst fertilizers in two methods of applications on immature oil palm tree on an inland soil.

METHODS OF FERTILIZER PLACEMENT With the exception of the contain plots, all the fertilizers were buried, in trio pockets (10-15 cm deep) about 1.5 m from the palm. In the control plots, the fertilizers were broadcast within the weeded tidy supply (GCB). The palm performance was evaluated by their vegetative addition, FFB yield, and leaf consentient food content. OIL PALM PERFORMANCE AS bear on BY FERTILIZER PLACEMENT The palms at 60 months after planting (MAP) s howed better growth with the compound ferti! lizers broadcast (GCB) than all the fertilizers buried (Figure 1). The vegetative parameters, such as frond length, frond dry weight, frond yield and leaf area, were significantly higher in the GCB treatment. The subsoil placement of straight fertilizers generally performed the worst in...If you want to get a full essay, order it on our website: OrderEssay.net
