The aim is to know the potential of chilli production in sub obtimal soil and to know the effect of organic and inorganic fertilizers on the growth and production of chilli plants. The method used in this study was in the form of a field experiment arranged in a Randomized Block Design (RCBD) with a 2 x 4 Factorial experiment with 4 replications. The first factor is organic fertilizer consisting of: B0: without manure Bk: 500 grams / staple. The second factor is inorganic fertilizer consisting of: P0: 10 g urea (Control), P1: 10 g urea + 10 g SP-36 + 10 g Kcl, P2: 10 g urea + 15 g SP-36 + 15 g Kcl, P3: 10 g urea + 20 g SP-36 + 20 g Kcl. The results showed that organic fertilizer treatment significantly affected the growth of height, diameter, number of branches, age of flowering, and the number of fruit of cayenne pepper. Inorganic fertilizer treatment (SP-36 and KCL) had no significant effect on the growth and production of cayenne plants. The best interaction is the combination of B0P1 fertilizer (urea + SP-36 + KCL) and BKP0 (urea + manure) treatment. The application of organic and inorganic fertilizers separately is stronger than when applied together. Damage to plants caused by curly diseases in the rainy season due to poor drainage (sub-optimal) land conditions. Application of organic and inorganic fertilizers to be applied separately. Optimal land management is needed by making good drainage to reduce the level of attack of critical diseases, especially in the rainy season.

Low soil fertility rates and not yet intensive crop cultivation have an impact on the declining trend on tomato production in the eastern multiplication. Low productivity of tomatoes due to low quality of seedlings and pest and disease attacks. Efforts to increase tomato production have been carried out, among others, by improving cultivation techniques, namely by improving the physical properties of the soil by adding organic materials and adding nutrients using inorganic fertilizers. The design of this study is; Complete randomized design with factorial analysis 2 x 4 and repetition as much as 3 times. In the first factor, the media mixture consists of 2 levels, namely T0 = Soil, T1 = Mixture of soil, manure, and chaff (2:1:1). The second factor is the combination of fertilizer K and P consists of 4 stages, namely: P0 = without fertilizer, P1 = 5gram KCL and 15grams SP-36, P2 = 10 grams KCL and 15 grams SP-36; P3 = 15 grams KCL and 15 grams SP-36. The number of polybags in the study is 24 with a per polybag size of 30 x 40 cm. The results showed the addition of manure and chaff gave clear results to the growth and production of tomatoes. The application of KCl and SP-36 fertilizers affect the high growth of plants but does not affect the production of tomato plants. Recommendations for the use of organic materials and KCL fertilizers, SP-36 is applied separately

Palm oil is one of the plantation commodities that contributes as a reliable contributor to foreign exchange. The raw materials produced from oil palm trees include palm oil, palm kernel oil, and palm kernel pulp. Each product has a commercial value, but of the three products that currently have potential is palm oil, better known as CPO (Crude Palm Oil). The ever-increasing world consumption of palm oil makes companies or plantations that cultivate palm oil have to work hard to meet the needs of palm oil. The increase in oil palm production was due to the expansion of oil palm plantation areas. oil palm results in lost opportunities to achieve yields that meet crop productivity standards. The productivity of oil palm plants varies greatly according to environmental conditions (climate, land conditions), genetic conditions (plant material and plant age), and the interaction between the two in the technical form of culture implementation. This study aims to determine the production of fresh fruit bunches (FFB), the average weight of bunches (BJR), and the number of bunches per TPH on that type of soil. This research was conducted in the oil palm plantation of PT. Mitra Proud Utama is located in Anggana District, Kutai Kartanegara Regency. Based on the results of the research on the potential production of fresh fruit bunches on three types of soil, it was shown that soil type did not affect the number of bunches and flowers. The production of the best number of bunches and flowers was on entisol soil of 10.00 bunches/tree, spodosol soil of 9.98 bunches/tree, and ultisol of 8.85 bunches/tree. Soil type has a significant effect on the average bunch weight and the best BTR on 10.77 kg ultisol soils, 9.79 kg on spodosol soils, and 9.17 kg on entisol soils and has not reached the S3 land class standard. Potential Number of bunches per The best TPH was on ultisol soil (yellow) 23.7 bunches/TPH.

Gebi Hiskia Anggraini, Faculty of Agriculture, Widya Gama Mahakam University Samarinda 2020, " The Effect Of Urea, Kcl, Sp-36 Fertilizer On Production At Some Age Of Natural Rubber Plant (Hevea Brasiliensis Mull.Arg)" under the guidance of Mahdalena and Akhmad Sopian. The purpose of this study was to determine the correct dosage of fertilizer to increase the production of natural rubber plants, to determine the effect of rubber plant age and the combination of Urea, KCl, SP-36 fertilizers on increased production,this research was conducted for 3 months, from March 2020 to July 2020. The research location was in a rubber plantation located in Tondoh Village The study used a divided plot design or divided plot consisting of 2 factors with 3 replications, the main plot factor was the age of the rubber plant which consisted of 2 levels of age 8 years and 10 years, the second factor of the sub-plots was Fertilizer consisting of 5 levels, namely: P0 = Without fertilizer, P1 = Urea fertilizer 350 g, KCl 300 g, SP36 260 g / tree, P2 = KCl fertilizer 300 g, SP36 260 g / tree, P3 = Urea fertilizer 350 g, SP36 260 g / tree, P4 = Urea fertilizer 350 g, KCl 300 g / tree The results showed that the application of Urea, KCl, SP-36 fertilizers had a significant effect on latex productivity, latex wet weight, and latex dry weight on the production of rubber (Hevea brasiliensis Muell. Agr). At the age of 8 years and 10 years with the combination of Urea, KCl, SP-36 Fertilizer treatment did not manifest a significant effect on the results of Production, Wet Weight, Dry Weight, and Dry Rubber Content Dry Rubber Content Natural rubber (Hevea brasiliensis Muell. Agr) belongs to quality II which has a low Dry Rubber content that means that the water content in the latex is relatively high Key words: Latex and Inorganic

Suboptimal soil conditions can lead to reduced latex production and quality. One of the main factors influencing latex production is soil fertility, where fertile soil with adequate nutrient content can enhance latex yield. One of the efforts to improve production is through proper fertilization, where the dosage and timing of phosphorus (P) and potassium (K) application must align with the needs of the rubber plant and the condition of the soil. By using appropriate P and K fertilizers, rubber farmers can increase both latex yield and quality. This research was conducted using a factorial experiment with a randomized complete block design (RCBD) and three replications. The first factor was the amount of TSP fertilizer, divided into four categories: P0 = without TSP application per tree, P1 = 175 g per tree, P2 = 200 g per tree, and P3 = 225 g per tree. The second factor was the dose of KCl fertilizer, consisting of four categories: K0 = control, K1 = 200 g per tree, K2 = 250 g per tree, and K3 = 300 g per tree. The findings indicated that TSP fertilizer application had a significant effect on dry rubber content, while KCl doses did not show a significant effect on latex volume, wet latex weight, dry latex weight, or dry rubber content. Keywords: Hevea brasiliensis, latex production, phosphorus, potassium
