Abstract

Maluku in general and Ambon municipality in particular is a region with the lowest peanut production as compared to its national production. Cambisol is one of soil type that has good soil physical properties, but it is low in N and P contents and has an acidic reaction that inhibit the growth of peanut plants.  The research was conducted in a plastic house in Halong Village, Teluk Ambon Baguala Subdistrict, from April to Juli 2012. This research used a Completely Randomized Design with two factors, i.e. factor 1 with three levels of dolomite fertilization, consisting of D0 (without dolomite), D1 (0.3g dolomite per pot), D2 (0.6 g dolomite per pot), and factor 2 with three levels of phosphate fertilization consisting of P0 (without phosphate fertilizer), P1 (0.7 g SP-36 per pot) and P2 (1.4 SP-36 per pot). The results showed that the application of SP-36 increased the number of root nodules and yield of peanut. Response was even better if accompanied by the application of dolomite. Leaf N uptake could be enhanced by application SP-36, but it was independ from the application of dolomite. The highest peanut yield of 41.83 g per pot was achieved with the fertilizer combination of D1P2  (0.3 g dolomite per pot and  1.4 g SP36 per pot)

Abstract

Nitrogen is a major nutrient for plant growth. Nitrogen function to increase vegetative growth, increase the number of tillers and increase the number of grains/clusters and increase the size of rice grain. The purpose of research was to analyze the availability of N in the soil and plant N content, and calculating fertilizer needs to increase rice productivity. Research was conducted using survey methods with an area sampling approach, conducted in October 2012 - January 2013. The research area was 590.6 ha. The soil total N ranged from very low (KP3 and 5 at 0.06% and 0.09% respectively), until low (KP 1, 2, 4, 6 and 7 at 0.14%, 0.15%, 0.13% 0.17% and 0.14% respectively. Meanwhile, the plant N sampled from the start of grain filling until harvest were low, ranged from 1% - 1.31%. The doses of fertilizer needed to sustain 5 ton ha-1 rice for the next planting season by adding Urea were as much as KP 1 (224.3 kg ha-1), KP 2 (224.25 kg ha-1), KP 3 (224.7 kg ha-1), KP 4 (224.35 kg ha-1), KP 5 (224.55 kg ha-1), KP 6 (224.15 kg ha-1) and KP 7 (224.3 kg ha-1).

Abstract

Dams irrigation system is important facility to ensure the water availability during rice cultivation. The aim of this study was to verify the condition of Way Bini irrigation system in providing irrigation water and water distribution system to meet the needs of rice cultivation in Savana Jaya Village, Waeapo Subdistrict, Buru District. The research used survey method. The results showed that the irrigation water debit required for appropriate rice cultivtion was 677.16 L/sec (0.68 m3/sec) which was smaller than that of the Way Bini dam; 750 L / s (0.75 m3 / s), while the efficiency of the irrigation water requirement was 70% which was categorized as good to excellent.

Abstract

The experiment was conducted to determine and map the land suitability of  lychee plant in Naku village. The results showed land units that belong to the class of land suitability (S1)  were GD1 and GD2 covering  4.6 ha (2.42%). Land units that included the class of  marginally suitable land (S3) was GD4 covering 1.9 ha (1.0%). The limiting factor was the slope of 15-30% and  depth of solum 50-75 cm. Not suitable land (N) were the land units GD3, GD5, GD6, GK1, GK2, GK3, GK4 and A1 covering 184.1 ha (96.58%)   Limiting factor on the land unit GD3 was depth of solum <50 cm, on GD5 was 30-45% slope, and solum depth of 50 cm, on GD6 was a slope > 45%, on GK1 - GK4 was coarse/very coarse texture, on GK5 was the slope of 30-45 % as well as coarse texture, on GK6 was slope > 45% and very coarse texture, and the limiting factor for the A1 unit was a very coarse texture. The potential land capacity for Lychee plants in  Naku Village was area of 6.5 ha or 3.41% of the land area in the Naku village.

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.
