Abstract

Fertilization efficiency which could enhance soil productivity is determined by type, application method and appropriate dose of fertilizers.  A green house experiment to study effect of different maturity level of ela  sago bokashi and some dosage of  SP-36 fertilizer on P-uptake and growth of maize (zea mays l.) on ultisols has been performed. The experiment was set up in three-replicates factorial Randomized Block Design. The treatments were  three maturity level of ela sago bokashi i.e. 2, 3 and 4 weeks; and four dosages of SP-36 fertilizer i.e. 0, 2, 4 and 6 g/10 kg of soil. The results showed that application of bokashi regardless of their maturity at the same time with each  doses of SP-36  increased P uptake, plant height and stem diameter of maize. Giving four-week ela sago bokashi with 6 gr/10 kg of soil of SP-36 was the best treatment to improve P uptake, plant height and stem diameter of corn crop up to  0.15%, 140, 60 cm and 1.64 mm respectively.

Abstract

The study was conducted to quantify the land use changes that have occurred in the watershed Batugajah and evaluate the impact of changes in land use to changes in surface flow, inter flow and base flow. The results showed that the change in land use in the watershed Batugajah of the year 1998-2010 as follows: The decline occurred from 215.70 ha forest area to forest area 58.88 ha or 28.73% decrease, increasing the wide use of residential land of 25 ha to 183.62 ha, an increase of 29.06%; vast improvement hamlet of 155, 65 ha to 221.78 ha, an increase of 12.12%. The impact of land use changes as follows: Runoff increased from 2288.35 mm to 2291.35 mm; annual runoff  increased from 2525.81 mm to 2646.70 mm; interflo) increased from 103.382 mm to 244.99 mm; Water yield increased from 210.48 mm to 220.56 mm and the base flow  dropped 141.07 mm to 110.35 mm.
