Abstract

This study was aimed to identify the distribution of productivity and quality of Temanggung tobacco, identify relationships between soil erodibility with soil compaction and productivity quality of Temanggung tobacco, and identify relationships between soil erodibility index with productivity and quality of Temanggung tobacco. The study was conducted by field survey method with the object of study was tobacco fields in Temanggung Regency, Central Java. Based on the data obtained, two maps i.e. map of productivity distribution and map of Temanggung tobacco quality. The results showed that the soil compaction affected the value of erodibility index. The higher of the soil compaction, the lower was the value of soil erodibility. It was because the compaction of the soil influenced one aspect of erodibility. The soil compaction affected the productivity but did not affect to the quality of Temanggung tobacco. The more compact the soil, the lower the productivity of the land, it was because root development was hampered by the dense soil, thus affecting the development of other plants (leaves). While erodibility did not affect productivity, it affected the quality of tobacco. The higher erodibility indicated the lower quality tobacco. This was because the high soil erodibility increased soil sensitivity to erosion.

Abstract

Temanggung is known as best quality tobacco producer. The potential production of Temanggung tobacco ranges from 900 to 1200 kg ha-1, but the present tobacco production is still low at 703 kg ha-1. The type of tobacco that is widely cultivated in Temanggung is Kemloko tobacco, which is known as the best local tobacco variety. This study was aimed to explore the relationship of Ca, Mg and Na availability for production and quality of Kemloko Tobacco in Temanggung Regency, Central Java. Soil samples were collected from field at 0-20 cm depth. The chemical analysis results showed that the distribution of Ca availability was low to high (2-20 me 100 g-1), availability of Mg was high to very high (2.1 to> 8 me 100 g-1), availability of Na was low to medium (0.1-0.4 me 100 g-1). The results of correlation analysis were as flows: Ca and production was 0.1520, Ca and quality index was 0.0660, Mg and production was -0.0676, Mg with quality index was (-0.0419), Na and production was -0.2304, Na and quality index was -0.1023. All correlation coefficients were weak. The average yield of moderate tobacco production was 311-609 kg ha-1 with the result of the average quality index entering into the very low class of 20-48.

Abstract

One of the tobacco producing centers in Indonesia is Temanggung District, Central Java. Varieties that are commonly grown in Temanggung Regency is Kemloko varieties that produce the best quality (srinthil) with high nicotine and used as raw material for making kretek cigarettes. This study was aimed to analys the relevance of nutrient status of N, P, K in soil on production and quality index in Temanggung, and arranging distribution map of N, P, K in Temanggung. The study was conducted by field survey. Results showed that there was no significant correlation between N, P, K on productivity and quality of tobacco  Kemloko varieties in Temanggung regency, Central Java. N, P, K correlation value to productivity that -0.1125, 0.2247, -0.1856. N, P, K correlation to quality index -0.0002, 0.2354, 0.0836. There was no significant correlation between N, P, K with productivity and tobacco quality index on 2016 planted season  due to high rainfall occurring throughout 2016. Distribution of N-total  in tobacco producing centers in Temanggung was low (0.14%), to moderate (0.35%), P-distriburtion is very high (23.15 ppm P-50.88 ppm P) and K distribution was average (0.48 me 100 g-1) to very high (1.57 me 100 g-1).

Abstract

This study aimed to analyze the effect of soil chemical consisting of pH, C-organic, CEC, and base saturation on the production and quality index of Kemloko tobacco varieties, and to identify distribution map of soil chemical properties. The study was conducted by field survey and analysis spatial was used Inverse Distance Weighted interpolation method. The results showed that distribution of soil chemical properties in Tobacco Centers at the Temangung Regency consisting of acidic pH value with a range of values 3,96-6,97, soil C-organic ranges low with a range of values 0,19-6,79%, soil CEC ranges from high to very high with a range of values 10,98-67,84 me/100g-1, and low base saturation categories with a range of values 13,24-82,77%. Correlation coefficient obtained between the soil chemical properties and tobacco’s production; each of them is sequential, i.e., 0,112, -0,204, 0,005, -0,027 in the weak to very weak category. While the level of coefficient correlation between soil chemical properties and tobacco quality index, each of them is sequential, i.e. -0,001, -0,141, -0,175, 0,165 in the very weak category. This was because productivity and quality index of Kemloko tobacco varieties in Tobacco Centers at the Temanggung Regency on 2016 planted season due to high rainfall occurring throughout 2016 on the tobacco processing phase.
