This study aimed to findthe method that can determine the right amount of nitrogen need using either a conventional technique or a leaf color chart and to determine the rate of nitrogen better for rice plant growth and yield. The study used a two factorial experimental design. Those factors were three rates of fertilizers and two kinds of fertilizer applications. The rate of fertilizer needed by the plant was either 200 kg ha-1 as suggested by the leaf color method or 250 kg ha-1 as shown by the conventional method. Based on the plant height and percent of empty grain, the leaf color chart method is better in determining the amount of nitrogen needed by the plant. The addition of 250 kg ha-1 nitrogen tends to decrease the percent of empty grains. Keywords: Leaf color chart, Nitrogen, and Rice.

The need for soybean increasing every year causes soybean imports to be done continually, so an effort to increase the production must be done to reduce dependency on imported soybean. This study aims to determine the characters that can be used as an indicator of selection to increase soybean yields. The study was conducted in the village of Sa'atu, Coastal Poso Subdistrict, Poso Regency, Central Celebes Province, from January to April 2011. Using a randomized block design (RBD) with 30 genotypes (varieties) as the treatments that were repeated 3 times, so it obtained 90 units of experimental plots. The observed variables were plant height at harvesting time, flowering age, harvesting age, number of pods per plant, number of seeds per pod, number of productive branches per plant, total weight of pods per plot, weight of 100 seeds and yield of seeds. The results showed that plant height at harvesting time, harvesting age and number of seeds per pod have genetic variability coefficients that were moderate while the other traits were high. The number of pods per clump and the number of seeds per pod have moderate heritability values while the other traits were high enough. Harvesting age has a significant negative genetic correlation with the yield while the number of productive branches, total weight of pods per plot and weight of 100 seeds have significant positive genetic correlations with soybean yields. Weight of pods per plot is a trait that has high direct effect on and significant positive correlation with the yields so it can be used as an indicator of trait selection to improve soybean yields.

Cacao is one of important plantation crops grouped in the Sterculiaceae family. Sulawesi is the main area of cacao production and has a number of superior clones, such as Sulawesi 1 and Sulawesi 2. Based on data in 2012/2014 cacao production to consumption reached 174,000 tons, while in 2013/2014 was projected a deficit of 115,000 tonnes. Nonetheless, cacao agribusiness in Indonesia is still facing complex problems, among others gardener productivity is still low due to borer attacks cacao, the quality of products and the number is still low and still not optimal development of cacao products and providing superior amount of cacao seedlings. The primary problem of cacao production recently is low productivity. The main cause of low cacao productivity in Central Sulawesi is the use of inferior clones. To enhance cacao productivity, it is crucial to use cacao clones having high genetic potential via tissue culture or micropropagation techniques. The aim of this experiment was to assess the effect of different concentrations of 2,4-D and coconut water on the growth of cacao callus via in vitro culture. This experiment used Completely Randomozed Block Design in factorial patteren with treatments tested namely 2,4-D and coconut water concentrations. The concentrations of 2,4-D tested including 1 ppm, 2 ppm and 3 ppm, whilst coconut water concentrations tested consisting of 10%, 15% and 20%, and therefore there were 3 x 3 = 9 treatment combinations. Each treatment utilized 4 replications; and each unit combination used 5 explants (staminodia). Results of this experiment indicated that the addition of 3 ppm 2,4-D and 10% coconut water had a highly significant effect on the callus color 4 weeks after culture. The addition of 3 ppm 2,4-D in culture media showed a significant effect on callus color 4 weeks after culture, but had an insignificant effect on the callus formation, callus color 8 weeks after culture an callus texture. Supplementation of 20% coconut water had a significant effect on callus texture 8 weeks after culture, whilst the addition of 10% coconut water showed a significant effect on callus color 4 weeks after culture.

Nickel (Ni) and associated minerals (Cr and Mn) are naturally occurring substances in ultramafic laterites soil. It may be found in our vegetables and grains when agriculture is grown in ultramafic laterites. This study aimed to assess the contamination of Ni in edible crops affected by soil volume in mono- and mixed cropping on limonitic laterite soil. The investigation was conducted on Peanut (Arachis hypogaea L.) and Choy Sum (Brassica rapa var. parachinensis) in three different pots sizes-representing soil volume to support root growth, which was filled with 0.5 kg (small), 1.0 kg (medium), and 1.5 kg (big) of limonitic laterite soil, respectively. The limonitic soil has a 7.884 mg kg-1 Ni concentration. The experiment shows that Ni concentration in peanut and Choy Sum shoots of mono-cropping in small, medium, and big pots achieve 20, 90, 120 mg kg-1 and 51, 67, and 95 mg kg-1, respectively. Meanwhile, in mixed cropping, Ni concentration in small, medium, and big pots of peanut and Choy Sum shoots are lower only by 33, 50, and 51 mg kg-1 and 15, 52, and 63 mg kg-1, respectively. Contamination of Ni in Peanut and Choy Sum shoots increases with the increasing soil volume, and mixed cropping is a potential strategy to reduce the acquisition of Ni.
