Abstract

This research was aimed to determine the effect of the PGR 2.4-D (Dichlorophenoxy Acetid Acid) in various concentrations on induceing callus of Dombu potato (Solanum tuberosum L.). This research was performed based on Completely Randomized Design (RAL) with 6 treatments and 3 times repetation, so there were 18 experiment units. Each experiment used 3 explants so as there were 54 explants. The combination of concentration of the tested PGR in the culture media were T1 = MS0+ 2.4-D 0 ppm (control), T2 = MS0+ 2.4-D 0.5 ppm, T3 = MS0+ 2.4-D 1 ppm, T4= MS0+ 2.4-D 1.5 ppm, T5 = MS0+ 2.4-D 2 ppm and T6 = MS0+ 2.4-D 2.5 ppm. The results showed that callus induction was appeared in the concentration of 1.0, 1.5, 2.0, and 2.5 ppm. Callus was generally formed on the Day-8 after plantation. Callus color was mostly greenish transparent, callus texture was mostly crumb type, and callus formation percentage was almost 100%. The best media for inducing the callus was in treatment T4 (1.5 ppm 2.4-D), it referred to the formed callus biomass

Abstract

Cyperus rotundus L. and Ageratum conyzoides L. are commonly found in tomato field as weeds species. Weed compete with the crop for nutrient, water and light. In addition, weed released allelopathy that inhibited the growth of crop. The aim of this study was to compare the ability of allelopathy from C. rotundus L. and Ageratum conyzoides L. root extract to inhibit tomato plant growth. The study was conducted in Completey Randomized Design with two factors. The first factor was root extract from either C. rotundus L. and A. conyzoides L. as allelopathy. The second factor was concentration of root extract from both weeds (100, 300 and 500 g/ml). Each treatment combination was repeated four times. The results showed that A. conyzoides L. root extract had higher inhibition to growth of tomato plant than C. rotundus L. root extract. Increasing root extract concentration from both weeds increased inhibition of tomato plant growth.

Abstract

Weeds such as Cyperus rotundus L. dan Ageratum conyzoides L. release allelopatic compounds which can inhibit the growth of crops. The aim of this study was to compare the inhibition of allelopatic compounds contained C. rotundus L. and A. conyzoides root exctract to Brassica rapa L. growth. This study was conducted in a greenhouse and was based on Completely Randomized Design with two factors. The first factor was type of root extracts (extract from either C. rotundus root or A. conyzoides root) and the second factor was concentration of root extract. Root extract concentrations added to growth medium of B. rapa L. 10 days after planting were 0, 100, 300 and 500 g/L respectifely. The addition of root extract was repeated every week until crop harvested. The results showed that there was not significantly different between C. rotundus and A. conyzoides roots extract to inhibit B. rapa growth. Increassing of root extract concentrations from both roots increased inhibition of B. rapa growth.

Abstract

Liquid organic ferilizer is fertilizer produced from organic materials, such as weathering food scraps, animals and human organic waste that has been processed, can be solid or liquid. Liquid organic fertilizer contains carbon at 7,1% and a nitrogen content of 3,3%. This studi aims to determine the effect of the horizontal “soil organic” planting system through the application of mustard plants (B. rapa L.) and find out at what dosage the optimum liquid organic fertilizer for the of mustard plants. This studi was designed in a randomized block design with 11 treatments and 3 replication. Treatment arrangement: P0 (whitout fertilizer), P1 (1 mil liquid organic fertilizer), P2 (2 mil), P3 (3 mil), P4 (4 mil), P5 (5 mil), P6 (6 mil), P7 (7 mil), P8 (8 mil), P9 (9 mil) and P10 (10 mil). The result of the study showed the best growth for plant height in P2 with a value of 11,78, for the number of leaves in P2 with a value of 11,20, for the fresh weight of roots in P0 with a value of 2,45, for root dry weight at P6 with a value of 1,1, for plant wet weight in P5 with a value of 15.36 and for plant dry weight in P5 with a value of 1,65.

Abstract

Potato (Solanum tuberosum L.) is one of crops which cultivated by farmers in Central Sulawesi. These potatoes are traditionally cultivated without going through the breeding process, so they have high variations. This study aims to obtain information on genetic diversity, heritability, and correlation between the characterics of potatoes from farmers in Napu who are still cultivating potato crops. Design used in this study was a randomized block design with two replications. The results showed that tuber color and harvest age had a small coefficient of genetic diversity. The heritability values ​​of tuber color are include in the small category, Diameter of stem, number of leaves, leaf length, leaf width, leaf color, tuber length, tuber diameter, tuber weight, number of tuber and harvest age in this study are include in the high category. So that, these characteristics can be derived and selection can be made. In Napu potatoes, the number of tubers was genetically positively (medium) correlated between plant height and stem diameters, plant height with leaf width, leaf length with leaf width, leaf length with tuber diameters and tuber diameters with the number of tubers. While the positive correlation was very significant (strong) between plant height and leaf length, and very significant (strong) negative correlation between leaf color and tuber length, so can be used as a selection criteria for increasing potato crops.

Abstract

Study of composition and community structure of zooplankton in Talaga Lake was conducted from February to March 2019. The aimed of this research was to know the composition and structure of zooplankton in Talaga lake, Central Sulawesi. Samples were collected at four station by using purposive sampling method. The identification results have found 4 genus of zooplankton with each composition 71 % of Cyclops, 22 % of Daphnia, 0,34 % of Paramecium and 6,64 % of Chaoborus. The zooplankton abundance is around 11.6-17.2 ind/l. Community structure of zooplankton in Talaga Lake is unstable which shows by the low value of diversity index (0.68 to 0.8) and uniformity index (0,49-0,57). The value of dominance index which is in range 0.51-0.58 has also shown that there is dominant type of zooplankton.

Abstract

The research "Primary Productivity of Lake Sibili of Tawaeli District, Palu City, Central Sulawesi" was carried out from January to February 2019. This study aims to determine the primary productivity of waters and the physical and chemical parameters of Lake Sibili and as a first step in the use of Lake Sibili sustainable. This study was carried out using the method of oxygen light bottles and dark bottles. The results of the research have shown that station III has the highest net photosynthesis with a value of 1.875.0 mgC/m3/day (Table 2) this is caused by the temperature and pH of the station is relatively high which has an average temperature of 30.3 oC and average pH - 7.6 so that this can increase the rate of photosynthetic activity by phytoplankton while the lowest net photosynthetic value is at station I with a value of 812.4 mgC/m3/day which has a relatively lower temperature and pH compared to other stations which have an average temperature average of 28.9 oC and average pH 7. so that based on primary productivity values obtained during the study, the waters of the lake Sibili can be categorized as Eutrophic waters.
