Abstract

The Cilembu sweet potato is the popular food crop from specific location in Sumedang, West Java. Sweetness degree is one of key indicators for this commodity. Sweetness degree relate to sugar content. Currently, Cilembu sweet potato variety was grown by farmers is Rancing. They were local culture on cultivation and storage of Cilembu sweet potato. Study of Cilembu sweet potato based on land characteristics on cultivation location and sweetness quality along storage periods between different cultivation locations is limited. The objectives of this study were to determined influence of land characteristics of cultivation locations and storage periods on sweetness quality of Cilembu sweet potato. Samples were taken from harvested tubers from Cilembu, Rancakalong, Sukasari, Cicalengka, and Jalaksana cultivation location using purposive sampling method. Sweetness degree was measured by total sugar content using luff schoorl method. The experiment design was used split plot design. The experiment room controlled at the same condition. The storage periods was observed at 0, 1, 2, 3, and 4 weeks after harvest. The role of land characteristics on the sweetness quality of Cilembu sweet potato was used analysis of regression and t test for equality of means. The result showed that storage periods was significantly affect the sweetness quality of Cilembu sweet potato, while the cultivation locations did not significant influence on sweetness quality. They were not interaction between both factors. The chemical and physical soil properties, elevation and climate properties affect differences of sweetness quality of Cilembu sweet potato on different cultivation locations.

Abstract

Respirasi tanah terdiri atas respirasi autotrof dan heterotrof. Pada lahan gambut, respirasi heterotrof setara dengan laju dekomposisi bahan gambut. Penelitian ini bertujuan mengembangkan model potensial redoks (Eh) tanah sebagai penduga respirasi heterotrof dari perkebunan kelapa sawit pada lahan gambut tropika. Respirasi tanah diukur menggunakan metode sungkup tertutup pada plot close-to-tree (berjarak 2 m dari pohon) dan far-from-tree (4.5 m dari pohon), sedangkan untuk respirasi heterotrof pada plot root-cut (4.5m dari pohon) yang disiapkan dengan pemotongan akar hingga kedalaman 80 cm dan diinkubasi selama 8 bulan. Respirasi tanah pada lokasi penelitian 40.81 ton CO2 ha-1.th-1, 50.53% darinya berasal dari respirasi komponen heterotrof (RKH). Respirasi heterotrof berkorelasi positif dengan Eh tanah pada pH 7 di kedalaman -30 dan -90 cm (Eh7~30 and Eh7~90) dan berkorelasi negatif dengan tinggi muka air tanah. Nilai koefisien korelasi linier sederhana yang signifikan, r= 0.84 dan 0.87; n= 12, dengan RKH masing-masing ditunjukkan oleh Eh7~30 and Eh7~90. Oleh sebab itu, kedua faktor tersebut dapat disarankan sebagai penduga RKH dengan persamaan: RKH (ton CO2 ha-1.th-1) = 18.2 + 0.029 Eh7~30 + 0.037 Eh7~90 (Eh dalam mV).

Abstract

One of the management challenges in pineapple cultivation at plantation scale is the still occurrence of disparity in land productivity across the cultivated area although the cropping practices have been implemented for many years. In the case of a pineapple plantation in Central Lampung Regency, contribution of soil biochemical properties in terms of various soil enzyme activities as a determinant factor of land productivity has never been elaborated. This research was aimed to study the relationships among biochemical and other soil properties with land productivity or pineapple yield at plantation scale. Rhizosphere soil-composite samples were taken purposively from 4 stations at the largest Indonesian pineapple plantation representing blocks with high and low yield and growth at vegetative and generative phase. Relationships amongst the studied parameters were evaluated using PCA and linear multiple regression analysis. The results showed significant contributions of the rhizosphere soil properties on the pineapple yield according to equation: Yield = 64.895 – 6.546 PCA1 +13.057 PCA2 – 7.722 PCA4 (R2= 0.612), where PCA1 consisted of soil available-P, available-K, and CEC; PCA2 was of soil base saturation, total microbe population, enzyme activities of cellulase and invertase, while PCA4 was of soil organic C, silt fraction, and phosphatase activities.
