Abstract

Effect of application of alang-alang compost and source of phosphorus fertilizers on growth and yield of peanut on critical land was studied during 1997/98 fiscal year. The experiment was conducted at farrner field in Subarang village, Solok district. Six treatments with three replica- tion rvere arranged in Randomized Complete Block De- sign. The objectives of the experiment were to investigate the elfect of application of alang-alang compost combined with source of phosphorous fertilizers on growth and yield of peanut on critical land. The treatments were combina- tion of organic matter and source of phosphorous fertilizers i.e: 1) SP-36 100 g/ha without organic manure; 2) rock phosphate I t/ha without organic manure; 3) alang-alang compost 5 t/ha + 100 kg/ha SP-36; 4) alang- alang compost 5 t/ha + 1 t/ha rock phosphate; 5) organic manure 5 t/ha + 100 kg/ha SP-36; and 6) organic manure 5 t/ha + I t/ha rock phosphate. Basal fertilizers was applied 50 kg/ha Urea and 100 kg/ha KCl. Peanut variety was Trenggiling with planting space 40 cm x 15 cm. The result of experiment showed that: 1) application of organic mat- ter such as alang-alang compost and organic manure increased yield of peanut around 750 kg/ha dry pod com- pare to without organic matter treatments; and 2) treat- ment combination of alang-alang compost with rock phos- phate tend to increase yield of peanut 1,1 t/ha dry pod compare to without organic matter treatments. Key word : alang-alang compost, critical land, rock phos- phate.
