This study aims to determine the effect of giving T. asperellum and compost on the growth and yield of shallots of the Palu Valley variety. This research was conducted on July to September 2019 in Oloboju Village, Sigi Biromaru District, Sigi Regency, Central Sulawesi Province. This research is a kind of experimental research that is designed by using a Randomized Group Design with grouping based on watering time. The treatments tested consisted of: P0 = Control (without treatment), P1 = T. asperellum 48g + 12 liters of water, P2 = T. asperellum 48g + 12kg compost and P3 = 12kg compost. To determine the effect of the treatment being tried, a diversity test was conducted. If the diversity test results show a real influence, then proceed with the Honestly Significant Difference test (BNJ) α = 0.05 to find out the differences between treatments. Treatment of various combinations of T. asperellum and compost significantly affected plant height at ages 15 and 25 HST, but had no significant effect on the number of leaves, leaf fresh weight, root fresh weight, leaf dry weight, root dry weight, number of tubers per clump, fresh tuber weight per clump, fresh tuber weight per plot and fresh tuber weight per hectare. The compost treatment gives a better effect on the height of plants aged 15 HST (average 15.09cm) and 25 HST (average 19.86cm).

This study aims to determine the right planting time to obtain optimal sweet corn results in intercropping systems with peanut plants. This research was conducted in the Agricultural Land of Petobo Village, South Palu Village, Palu City, Central Sulawesi for 3 months starting from September to November 2017. The research was carried out using a one-factor Randomized Block Design (RBD), by grouping based on water sources. The treatments that were tried were the intercropping system (TS) planting time, as follows: TS0 = Sweet corn grown together with peanuts; TS1 = Sweet corn planted with 2 WAP peanuts; TS2 = Sweet corn planted with 4 WAP of peanut; TS3 = Sweet corn monoculture. Each treatment consisted of 3 replications so that there were 12 test unit plots. The results showed that the planting time treatment significantly affected the growth and yield of sweet corn on intercropping systems with peanuts. The treatment of planting time together between peanuts and sweet corn gave better growth than other treatments, but the sweet corn monoculture (TS3) treatment gave better results compared to other treatments. Good growth and yield of both plants is recommended at the same time between peanuts and sweet corn in intercropping systems

Root and soil interactions will alter the biochemical status of the rhizosphere, the acquisition of nutrients and impacted to plant growth. The biochemical of the rhizosphere is strongly influenced by the agriculture input e.g. fertilizer, herbicides and farm management system. Application of fertilizers, their effects are robust and difficult tobe quantified. The effect of fertilizer on the biochemical status rhizosphere and plant growth is different depending on the type of fertilizers, growth media, plant species, and also the environment condition, while the effect on plants will be specific to each plant. This research investigated on the effect of N inorganic fertilizer inputs from two sources namely Urea (CO(NH2)2) and Ammonium Sulfate or ZA ((NH4)2.SO4), and different fertilization method (homogenous and localized). Experiments showed application of N-Urea and N-ZA fertilizers reduced the rhizosphere pH until 1,4 point. However, acidity of the rhizosphere reduced microorganism colonies and respiration rate.

This study aims to determine the factors that influence production and the magnitude of the factors that affect the production of Pepper in Kongkomos Village, Basidondo District, Tolitoli Regency. The time of research and data collection was carried out from October to November 2018. The determination of the purpose and location was determined intentionally, based on the consideration that Kongkomos Village had the highest production in Tolidoli, Basidondo Regency. The results showed that the factors influencing Pepper Farming Production were variable land area (X1), pesticides (X2), urea fertilizer (X3) and labor (X4). Variable X (land area, pesticides, urea fertilizer and labor) simultaneously has a significant effect on the Y variable (pepper production) with a value of R2 = 0.97, which explains that the contribution of variable X (land area, perticide, urea fertilizer, labor) ) to increase the fall of the variable Y (pepper production) by 97% while the remaining 3% is caused by other factors outside the production function model analyzed. From the results of the persial test it was revealed that the variables X1 (land area) 2,968, X2 (pesticides) 2,817, X3 (urea fertilizer) 4,488 and X4 (labor) 3,104 were greater than the value of t-table 2.78 which meant that the variable X1 (area land)), X2 (pesticides), X3 (urea fertilizer) and X4 (labor) have a significant effect on pepper production.

This study aims to determine the amount of production and business acceptance of clove nurseries CV. Nurhafiza in Pulias village ogodeide district tolitoli regency. The time of the study was conducted in November to December 2018. The determination of the data collection method was derived from primary data and secondary data and the analysis used was the break even point (BEP). The result showed that the principal return point value was reached during the production of 3,922 trees . this means that the production of 3,922 clove nursery business CV. Nurhafiza in pulias village, Ogodeide Tolitoli Regency, was not profitable and did not lose or TR=TC. Break even point revenue is Rp. 15.689.990, which means that at Rp. 15. 689.990, CV. Nurhafiza in Pulias Village , Ogodeide Tolitoli Regency, was not profitable and did not lose or TR=TC.

One area that has oil palm plantations is Makmur Jaya Village, Tikke Raya District, Pasangkayu Regency (formerly called North Mamuju Regency), West Sulawesi Province. One of the problems in the cultivation of oil palm is weeds. This study aims to determine the types of puzzle weeds in the oil palm plantation in Makmur Jaya Village, Tikke Raya District, Pasangkayu Regency, West Sulawesi Province. Based on the research, there were 3 types of puzzle weeds in the Makmur Jaya Village oil palm plantation, namely Cyperus compressus, C.rotundus, and Fimbristylis milliacea. Riddle weeds have leaves similar to narrow-leaf weeds, but have a mendong stem (consisting of only one long segment) and are also triangular in shape. Riddle weeds have allelopathic compounds which make it difficult for palm oil plants to grow.

The purposes of this research the examine the effectiveness various concentrations neem leaf ekstract on the intensity of attack Liriomyza spp on shallot Lembah Palu variety . Field research was carried out in Guntarano Village, Tanantovea Subdistrict, Donggala Regency, Central Sulawesi. This research conducted from February to April 2016 .The experiment was done using Randomized Complete Block Design with three replications, consists of six treatments, i.e. P0 : control (without aplication neem leaf ekstract); P1: neem leaf ekstract 10 gr /litre; P2 : neem leaf ekstract 20 gr / litre; P3 : neem leaf ekstract 30 gr / litre; P4 : neem leaf ekstract 40 gr / litre; P5 : neem leaf ekstract 50 gr / litre. To find out the effect of threatment, the analysis of variance, and the real influence is continued with the standard ά = 0.05 BNT test. The results showed that use of seed and leaf extracts of neem plant can control Liriomyza spp attack, only 3,04 percent of attack rate and shallot Lembah Palu variety productivity is 3,02/area.
