Abstract

Central Lampung is one of the areas that produce a lot of pineapple. Pineapple plants require potassium and magnesium nutrients to produce optimal fruit. The apparent appearance of chlorotic symptoms due to nutrient deficiency of potassium and magnesium makes it possible to be detected using aerial photographs. This study aimed to compare between Green Normalized Difference Vegetation Index (GNDVI), Normalized Difference Vegetation Index (NDVI) and spectral values for predicting potassium and magnesium contents in pineapple plants. The result of regression test showed that GNDVI had the best relationship than NDVI and spectral values. The equation for predicting the potassium nutrient in pineapple plant was with the formula: K=3,342-1,501(GNDVI) with RMSE value 0,1634. The Estimation magnesium in pineapple plants, NDVI had a better relationship with magnesium than with GNDVI and spectral values. The equations for magnesium estimation in plants with NDVI were obtained by using the regression test, i.e.: Mg=0,083+0,288(NDVI) with RMSE of 0,0342. Paired T-test values of GNDVI with potassium (-1,007) and NDVI with magnesium (-1,048) showed that t count was smaller than t table (2,015) and the significance value of both was greater than alpha (α = 0,05). So it can be said that the value of estimation with the actual value in the field has no difference that significant.

Abstract

To establish suitable lands for sugar cane plantation,  evaluation and suitability of existing land can be made using integration between Geographic Information System (GIS) and Land Suitability Assessment System (SPKL). This study was aimed to obtain the level of land suitability class in Garut regency, and arrange the direction of sugar cane plant development in Garut regency, West Java. The research activity was conducted in Geospatial Information and System Analysis Laboratory at Agricultural Land Resources Center Bogor and Garut Regency. All activities were carried out from April to August 2017. The research stages started from the preparation stage, data processing, field verification, determination of the land management and sugar cane cultivation development. Observation points were determined using purposive sample method based on the difference of limiting factors and accessibility. Results of SPKL program running and data merging on ArcGIS software showed that on sugar cane field in Garut Regency there are three results of land suitability evaluation according to moderately suitable (S2) marginally suitable (S3) and not suitable (N). The results of land suitability evaluation on sugar cane showed that the main limiting factor of growth were five types, i.e. drainage class (rc1), base  saturation (nr2), slope (eh1), average temperature (tc1), and soil depth (rc4). A total number of moderately suitable (S2) land for sugar cane in Garut is 131.558 ha, 514.633 ha for marginally suitable (S3) and 318.387 ha for not suitable (N).

Abstract

In Selorejo village, one of the centers of citrus-production in Indonesia, there are differences fruit productivity in between citrus-farmers. The high productivity citrus gardens produced 55.6 t ha-1 year-1 and in the garden with low productivity produced 26,7 t ha-1 year-1. Differences in these fruit productivity are due to differences in application of fertilizer and crop-management systems. This research was conducted by field survey and laboratory analysis. There were two observation sites as samples of the high productivity gardens (KPT) and the low productivity gardens (KPR). Soil samples taken from each garden were analyzed of soil-CEC, soil C-organic, Base saturation, soil texture, and pH to evaluate suitability of soil at each locations. Results showed that nutrient was not a dominant factor affecting fruit productivity. It is known that almost all soil characteristics suggest the same criteria.The difference was in the C-organic value that was at KPT only 0.78, whereas in KPR C-organic value reached 1,0. The actual land suitability of KPT is S3ehnr and of KPR is S3eh. Based on results of this study can be concluded that soil C-organic, land-slope and crop-management determined productivity of citrus garden.

Abstract

Mount Kelud is one of the most active volcanoes in Indonesia. Ash volcanic that released by Mount Kelud has some nutrients needed for plant, but requires a weathering process so as to provide nutrients in the soil. The soil that affected by Mount Kelud was given the addition of compost and urea fertilizer has residual effect for the next plant growth. This research was conducted in greenhouse of Agriculture Faculty, Brawijaya University from January until June 2017. This research used a completely randomized design with 5 treatments and 3 replications. The treatment consisted of A1: 2/3 soil residue (100% urea) + 1/3 goat manure compost; A2: 2/3 soil residue (100% chicken manure compost) + 1/3 goat manure compost; A3: 2/3 soil residue (100% cow manure compost) + 1/3 goat manure compost; A4: 2/3 soil residue (50% urea + 50% chicken manure compost) + 1/3 goat manure compost; A5: 2/3 soil residue (50% urea + 50% cow manure compost) + 1/3 goat manure compost. Variables of the observation were availability and uptake of NPK, plant height, number of leaves, number of pods, yield, and dry weight plant of okra. The results showed that compost residue and urea in the application of goat manure compost with ratio 2:1 had no effect in NPK availability on soil affected by Mount Kelud eruption. In plant’s parameter, there were effects on number of leaves at observation 12 weeks and P uptake, but no effect on N and K uptake, and okra’s yield.

Abstract

The purpose of this research was to analyze the effect of mycorrhiza based biofertilizer on the availability of P on acid soils and pineapple plant growth. The research was conducted in green hause owned by PT. Great Giant Pineapple, Central Lampung District. The treatments were four doses of Rhizagold biological fertilizer (10, 30, 50, and 70 g / seeds), and 1 control (without Rhizagold biological fertilizer). Five treatments were arranged in a completely randomized design with three replications. Observations were done destructively five times to produce 75 units of experiments. The results showed that the application of mycorrhizal based biochemical fertilizers did not give significant effect on all pineapple plant growth parameters and did not give significant effect on soil pH parameter, P-total, only gave significant effect on P-available. A dose of 30 g seedlings-1 showed the best dose to increase P availability on soil.
