Abstract

Irigasi pada tanaman nanas sangat penting karena mempengaruhi pertumbuhan dan produksi terutama di daerah tropika basah, namun biaya untuk irigasi sangat mahal. Penelitian bertujuan untuk mengetahui pengaruh irigasi dan mulsa organik terhadap pertumbuhan tanaman nanas di daerah tropika basah. Penelitian dilakukan dengan rancangan perlakuan faktorial (5 x 2) dalam rancangan acak kelompok dengan 3 kali ulangan. Faktor pertama adalah lama irigasi (I) yang terdiri dari 5 lama irigasi yaitu tanpa irigasi (I0), diirigasi 1 bulan (I1), diirigasi 2 bulan (I2), diirigasi 3 bulan (I3), dan diirigasi 4 bulan (I4). Faktor yang kedua adalah dosis mulsa kulit singkong terdiri dari 2 taraf yaitu 0 t ha-1 (M0) dan 50 t ha-1 (M1). Data pertumbuhan tanaman dianalisis ragam dan dilanjutkan dengan uji BNT pada taraf 5%. Tinggi tanaman 6 BST perlakuan yang irigasi 4 bulan bermulsa dan tidak bermulsa tidak berbeda nyata, dengan tinggi tanaman tertinggi pada perlakuan I4M1 yaitu 80,39 cm. Berat basah tanaman 4 BST yang irigasi 4 bulan bermulsa, irigasi 4 bulan tanpa mulsa dan irigasi 3 bulan bermulsa tidak berbeda nyata. Terjadi pemulihan keragaan tanaman terutama berat basah setelah memasuki musim hujan dimana kadar air tanah maksimum.

Abstract

Differences in productivity were observed in various land units on pineapple plantation in Central Lampung even with the same land and fertilization management. The nature of soil chemical and physical variability were thought to be the cause of these differences. The study was aimed to compare chemical and physical soil properties in land units with different pineapple productivity. Soil samples were taken from 6 units of land with low and 3 units of land with high productivity. The soil chemical properties meazured include available P and K, potential P and K, total N, pH, organic C, exchangeable cations, and available micro nutrients. The soil physical properties determined include bulk density, soil texture, and penetration resistance. The data was analyzed using T-test and correlation. The T-test revealed that the high productivity soils were significantly lower in available P, potential P, total N, and available Zn compared to the productivity soils. Furthermore, the high productivity soils were significantly lower in bulk density and penetration resistances both vertically and horizontally. There were significantly negative correlations between pineapple yields with potential P, available Zn, bulk density, and penetration resistance both vertically and horizontally. Overall analyses indicating that the physical properties were more as productivity determinant, particularly bulk density and penetration resistance, compared to the chemical properties. The chemical properties were more as residual conditions after nutrient absorption process to support pineapple productivity. In order to increase the productivity, it is necessary to manage the soil to lower bulk density and penetration resistance. Keywords: Crop management, nutrient management, penetration
