Abstract

Rice husk biochar applied to ultisol soil can increase soil fertility physically and chemically. The research aims to determine the role of rice husk biochar in increasing plant phosphorus uptake and its implications for hybrid corn productivity in ultisol soil. The research was conducted in Singkawang City, West Kalimantan, from July to November 2023. The research method was prepared using a one-factor randomized block design, namely without rice husk biochar, application of 6 tons ha-1 of rice husk biochar, and 10 tons ha-1 of rice husk biochar application. Each treatment was repeated 9 times. The results showed that the use of various doses of rice husk biochar on hybrid corn plants played a role in influencing the plant's ability to absorb phosphorus nutrients, increasing plant dry weight and root volume, with the best dose being 10 tons ha-1, but for variable plant yields the use of various doses Rice husk biochar obtained the same results.

Abstract

Sorghum is a cereal crop that can grow in hot and dry climates. Sorghum plants have varying stem heights depending on the variety. The growth of plant height can be inhibited by engineering by administering growth inhibitors (retardants). The growth inhibitor that is often used is paclobutrazol. The aim of this research is to obtain the best concentration of paclobutrazol that can inhibit growth, but can increase the yield of sorghum plants in peat soil. This research was carried out in Pontianak City, with a research duration of approximately 4 months starting from March to June 2023. This research used a Randomized Group Design consisting of 5 treatment levels, namely; s1 = 0 ppm (without paclobutrazol), s2 = 300 ppm, s3 = 600 ppm, s4 = 900 ppm, s5 = 1200 ppm. The variables observed in this study were plant height, stem diameter, leaf area, plant dry weight, root volume, panicle length, number of seeds per panicle, dry weight of seeds per panicle, seed weight per plot, and dry weight of 1000 seeds. The results of the research showed that giving paclobutrazol at a concentration of 1200 ppm was the best in inhibiting growth in terms of leaf area, plant dry weight and root volume parameters, but was not able to increase the yield of sorghum plants on peat soil. Keywords:  paclobutrazol, peat, sorghum INTISARISorgum merupakan tanaman serealia yang dapat tumbuh di daerah yang beriklim panas dan kering. Tanaman sorgum memiliki tinggi batang yang bervariasi tergantung dari varietasnya. Pertumbuhan tinggi tanaman dapat dihambat dengan dilakukannya rekayasa melalui pemberian zat penghambat tumbuh (retardant). Zat penghambat tumbuh yang sering digunakan adalah paclobutrazol. Tujuan penelitian ini adalah untuk mendapatkan konsentrasi paclobutrazol terbaik yang dapat menghambat pertumbuhan, namun dapat meningkatkan hasil tanaman sorgum di tanah gambut. Penelitian ini dilaksanakan di Kota Pontianak, dengan lama penelitian kurang lebih 4 bulan dimulai pada bulan Maret sampai Juni 2023. Penelitian ini menggunakan Rancangan Acak Kelompok  yang terdiri dari 5 taraf perlakuan, yaitu; s1 = 0 ppm (tanpa paclobutrazol), s2 = 300 ppm, s3 = 600 ppm, s4 = 900 ppm, s5 = 1200 ppm. Variabel yang diamati dalam penelitian ini adalah tinggi tanaman, diameter batang, luas daun, berat kering tanaman, volume akar, panjang malai, jumlah biji per malai, berat kering biji per malai, berat biji per petak, dan berat kering 1000 biji. Hasil penelitian menunjukkan bahwa pemberian paclobutrazol dengan kosentrasi 1200 ppm terbaik dalam menghambat pertumbuhan dilihat dari parameter luas daun, berat kering tanaman, dan volume akar, namun belum dapat meningkatkan hasil tanaman sorgum pada tanah gambut.Kata kunci : gambut,  paclobutrazol, sorgum

Abstract

Arumba Inpari is a superior rice variety highly sought after by the community due to its red- colored rice with high nutritional content in the form of phenolic compounds, serving as antioxidants that help counteract free radicals and prevent diseases in the human body. Microbial consortium is an organic fertilizer containing superior microorganisms (Azotobacter sp., Azospirillum sp., Bacillus sp., Pseudomonas sp., and Chytopaga sp.) that enhance soil fertility more effectively than single strains. This study aims to determine the optimal dosage of N, P, K fertilizers when applied in conjunction with a microbial consortium at a concentration of 40 ml/L water. This research was conducted in the Agricultural Land of Jalan Sepakat 2 Ujung, Bansir Darat, Southeast Pontianak, starting from August to December 2023. The study utilized a Completely Randomized Design consisting of 6 treatment levels of N, P, K fertilizers (%) and microbial consortium (ml/L); m0 = (100 + 0), m1 = (100 + 40), m2 = (75+ 40), m3 = (50 + 40), m4 = (25 + 40), and m5 = (0 + 40). The variables observed in this study consist of plant height, total number of tillers, root volume, plant dry weight, panicle length, total productive tillers, number of filled grains per panicle, 1000-grain weight, and grain weight per hill. The research results indicate that reducing the dosage of N, P, and K fertilizers starting from a 25% level can decrease plant growth. However, reducing the dosage of N, P, and K from 50% to 75%, accompanied by the application of a microbial consortium, yields similar results to the application of 100% N, P, and K with respect to the crop yield variables in rice plants.

Abstract

Oil palm farming in Pelepat Ilir District, Bungo Regency has two farming patterns, namely plasma and independent oil palm. Differences in farming patterns affect the income and expenses earned by farmers. This study aims to determine: (1) comparison of plasma and self-help farming income, (2) comparison of the feasibility level of plasma and self-help oil palm farming. The sampling technique used purposive sampling with 30 respondents. The data used were primary data (questionnaires, interviews, observations, and documentation) and secondary data (related agencies). The analysis techniques used are R/C Ratio, Price BEP, Production BEP, and T Test. The results showed that plasma oil palm farming income was IDR 6.466.945 while self-help was higher with a value of IDR 7.871.897. The results of the T test of plasma and self-help income show Sig 0.013 or there is a difference. The R/C ratio value of plasma oil palm is 1.31 and self- help is greater with a value of 1.37, both are feasible because > 1. The BEP price of plasma oil palm business amounted to IDR 1.538/kg/ha < IDR 2.023/kg/ha and self-help of IDR 1.48/kg/ha < IDR2.031/kg/ha, which means both are feasible to run. The BEP value of plasma oil palm farming production is 10.158 kg/ha < 13.356 kg/ha and independent of 10.507 kg/ha < 14.383 kg/ha, so both are feasible because the production value is greater than the BEP value.

Abstract

Public demand for cayenne pepper is high, so it is necessary to improve the quantitative characteristics of chilies, one of which is by selecting. This research aims to obtain information regarding the mean and interval values of several quantitative characters, inbreeding depression, heritability values, and selection progress from five generations resulting from crossing two cayenne pepper parents. The genetic material used consisted of two chili parents, namely the genotype IPB C321 (female parent), and IPB C290 (male parent) along with the results of crossing the two in the F2, F3, F4, and F5 generations with a total of 580 individual plants. The research results showed that based on the mean value between the F2 to F5 generations, there was an increase in the observed characters except at harvest age. The observed characters did not experience inbreeding depression. The heritability value in the narrow sense shows the high criteria for fruit length characters in the observed generation, fruit weight per plant and weight per fruit in the F2 generation, number of fruit per plant in the F2 and F3 generations, and fruit diameter in the F3 and F4 generations. Other generations have heritability values in the narrow sense of low and medium criteria. In general, the progress of selection for quantitative characters in the five chili generations studied showed a decline, although there were decreases and increases in the generations and characters observed.
