AbstractCorn, an important crop in Indonesia still has a low productivity, thus many efforts are required to fulfill its national demand. One of the solutions to improve corn yield is by applying biostimulant containing chitosan as an active ingredient. Chitosan has been proved to increase plant growth and resistance against diseases. The objective of this research was to study the effects of several chitosan formulas on the yield and diseases occurance in sweet corn (Zea mays var. Bonanza). The chitosan formulas tested were soluble liquid(SL), wettable powder (WP), nano chitosan (NN), and unformulated chitosan (CH). The experiment was arranged using a randomized block design with three replications. All chitosan formulas were applied by seeds soaking for 20 minutes, followed by foliar spraying on corn plants at three weeks after planting (WAP), with the concentration of 500 ppm (400 L/ha spray volume), every threeweeks until 9 WAP. Parameters observed were brix value, weight of corn cobs, weight of corn biomass, and plant diseases including downy leaves, leafblight and leaf rust. The results showed that NN formula increased the brix value up to 7%, the corn cob weight up to 49% and the biomass weight upto 34% compared to the control; whereas SL formula reduced the incidence of downy mildew by 53% at 3 WAP and leaf blight disease by 51% at 6 WAP. In addition, the incidence of corn leaf rust reduced 59-71% in corn plant subjected to all chitosan formulas. Based on the results, application of chitosan in NN formula was best in increasing yield, while in SL formula was best in reducing the incidence of important corn diseases.[Keywords: downy mildew, chitosan formula, seed treatment]AbstrakJagung sebagai salah satu komoditas pangan penting di Indonesia masih memiliki produktivitas yang rendah sehingga diperlukan usaha untuk memenuhi kebutuhan jagung nasional. Salah satu cara untuk meningkatkan hasil jagung adalah dengan aplikasi biostimulan yang mengandung bahan aktif kitosan. Kitosan telah terbukti mampu meningkatkan pertumbuhan dan daya tahantanaman terhadap penyakit. Penelitian ini bertujuan mempelajari pengaruh beberapa formula kitosan terhadap hasil dan kejadian penyakit pada tanaman jagung manis (Zea mays var. Bonanza). Formula kitosan yang diuji adalah cairan yang dapat larut (soluble liquid, SL), tepung yang dapat dibasahi (wettable powder, WP), nano kitosan (nano chitosan, NN), dan kitosan non formulasi (unformulated chitosan, CH). Percobaan dilakukan menggunakan rancangan acak kelompok (RAK) dengan tiga ulangan. Masingmasing formula kitosan tersebut diaplikasikan melalui perendaman benih selama 20 menit yangdiikuti dengan penyemprotan daun pada tanaman jagung berumur tiga minggu dengan konsentrasi 500 ppm (volume semprot 400 L/ha) yang dilakukan setiap tiga minggu sampai tanaman berumur sembilan minggu. Parameter yangdiamati adalah nilai brix, bobot tongkol jagung, bobot biomassa jagung, dan penekanan kejadian beberapa penyakit tanaman meliputi bulai, hawardaun, dan karat daun. Hasil penelitian menunjukkan bahwa aplikasi kitosan NNmeningkatkan nilai brix jagung manis hingga 7%, bobot tongkol jagung hingga 49% dan bobot biomassa hingga 34% dibandingkan dengan kontrol. Sementara itu, aplikasi kitosan SL dapat menekan kejadian penyakit bulai hingga 53% padaumur tanaman 3 minggu setelah tanam (MST) dan penyakit hawar daun hingga 51% pada umur 6 MST. Selain itu, kejadian penyakit karat daun jagung juga dapat ditekan 59-71% pada aplikasi keempat formula kitosan. Berdasarkan hasiltersebut, aplikasi kitosan NN paling optimal dalam meningkatkan hasil panen jagung manis, sedangkan aplikasi kitosan SL paling optimal dalam menekan kejadian beberapa penyakit pada tanaman jagung.[Kata Kunci: bulai, formula kitosan, perlakuan benih]

The growth and production of sweet corn (Zea mays saccharata Sturt) are strongly influenced by good genetics and environmental factors, including how to cultivate the soil so that the availability of nutrients is quite balanced. The long-term goal of this research is to determine the effectiveness of a combination of palm oil mill effluent (LCPKS) and cow dung waste (LKTS) with EM4 bio-activator applied to sweet corn (Zea mays saccharata Sturt). This study used a factorial randomized block design (RBD) consisting of 2 factors with 12 treatment combinations and 3 replications to obtain 36 research plots. The factors studied are the formulation factor of a mixture of palm oil mill effluent with cow dung waste, which is denoted by (A) consisting of A1 = 70% palm oil mill waste and 30% cow dung, A2 = 50% effluent palm oil mill and 50% cow dung waste, A3 = 30% palm oil mill waste and 70% cow dung waste. The dose factor with the symbol (D) consists of, D0 = control, D1 = 1.5 kg per plot, D2 = 3 kg per plot, D3 = 4.5 kg per plot. The parameters observed were plant height (cm), biomass samples (grams), sample production (grams) and plot production (kg). The results showed that different waste mix formulations and administration of different doses did not significantly influence plant height parameters because compost maturity must be assessed by measuring two or more compost parameters to prevent phytotoxicity. Therefore, quality assurance must be carried out on compost to determine the factors that cause phytotoxicity and also research must be intensified in determining lines that will be able to degrade waste faster, more efficiently and also produce non-toxic compost that mixes the soil produced in plant growth. In addition, care must be taken in selecting raw materials for composting. The results showed that the mixed waste formulations significantly affected the biomass of the sample, where the highest average was obtained in processing A3 (30% of palm oil mill waste and 70% of cow dung waste. The research results also showed that dosing had a very significant effect on biomass parameter sample, sample production and plot production where the highest average is in the D3 treatment (4.5 kg per plot).

This study aimed to examine Organonitrofos Plus fertilizer (OP) on sweet corn (Zea mays Saccharata L.) and its effect on changes in soil chemical properties of Ultisols. Organonitrofos Plus fertilizer is an enhancement of Organonitrofos fertilizer enriched with microbes at the beginning of the manufacturing process. Research was conducted in the greenhouse of Integrated Agricultural Laboratory of Lampung University. Treatment applied was a factorial of 4 × 2 × 3 with three replications in a randomized block design. The first factor was the dose of OP fertilizer (0, 10, 20, 30 Mg ha-1), the second factor was the dose of inorganic fertilizers (without inorganic fertilizers, and with inorganic fertilizers, namely Urea 0.44, 0.28 SP-36 and KCl 0.16 Mg ha-1), and the third factor was the dose of biochar (0, 10, 20 Mg ha-1). By a single OP fertilizers, inorganic fertilizers, and the interaction between the OP and the inorganic fertilizers increased the weight of dry stover, cob length, cob diameter, cob with husk and cob without husk of corn. OP fertilizers which are applied in Ultisols can improve soil fertility and increase corn production so that OP fertilizer can lessen the use of inorganic fertilizer and can be used as a substitute for inorganic fertilizer. RAE values were highest in treatment of O4K2B2 (30 Mg OP ha-1, with inorganic fertilizer, 10 Mg biochar ha-1) that was equal to 181%, followed by O2K2B3 (10 Mg OP ha-1, with inorganic fertilizer, 20 Mg biochar ha-1 ) with the difference in RAE value of 0.5%.
