Low productivity of corn can be overcome by using fertilizer regularly. Regular fertilization has several benefits, including increasing production and yield quality. Fertilization is divided into organic fertilizers and inorganic fertilizers. Organic fertilizers are fertilizers composed of biological material, one of which is chicken manure. Inorganic fertilizers are fertilizers designed by the fertilizer industry by mixing several high-value inorganic chemicals, one of which is urea. The objectives of research to decide the right combination of doses of chicken manure and frequency of application of urea fertilizer to obtain optimal growth and yield of corn plants. The research was conducted at INSTIPER KP2, Maguwoharjo Village, Depok District, Sleman Regency, Yogyakarta, from August to November 2022. The research design used was factorial which consisted of two factors and organized in a completely randomized design (CRD) with three replications. The first factor was the dose of chicken manure which consisted of three levels, namely control, 87 gram and 174 gram. The second factor was the frequency of application of urea fertilizer which consists of three levels, namely two times fertilization, three times fertilization and four times fertilization. Research data were analysis of variance (Anova) at a significant level of 5%. The research result showed that there was a significant interaction among the application of chicken manure 174 gram and the frequency of application of urea fertilizer four times the fertilization on the parameters of plant height and leaf area. The dose of chicken manure 174 gram significantly increased the growth parameters of plant dry weight and yield parameters of cob weight, cob diameter, weight of 100 large seeds and seed weight. The frequency of application of urea fertilizer four times of fertilization significantly increased the growth parameters of plant dry weight and yield parameters of cob weight, cob diameter, weight of 100 large seeds and seed weight.

The growth of tomato plant height can be inhibited by administering paclobutrazol and increasing fruit ovulation using GA3. This research aims to determine the application of gibberellin (GA3) and paclobutrazol on tomato growth and yield. This research uses the Split Plot Design field trial method. The main plot, namely GA3, consists of concentrations of 30 ppm, 60 ppm, and 90 ppm. The subplots consisted of concentrations of 0 ppm, 150 ppm, 300 ppm, and 450 ppm. Data were analyzed using a 5% level of variance. followed by the Duncan Multiple Range Test (DMRT) with a level of 5%. There was an interaction between GA3 and paclobutrazol treatment on plant height and length of stem segments at 40, 50, and 60 HST, total fruit weight per plot, and sweetness level. GA3 concentration of 90 ppm gave the best results in terms of fruit bunch parameters, total fruit weight per plant, hardness level, and shelf life. The paclobutrazol concentration of 300 ppm gave the best results on the parameters of number of branches at 30 DAP, fruit bunches, number of fruit, and storage time.

The increasing pattern of use of synthetic pesticides and the unwise use of synthetic pesticides can cause various further problems such as air, water and soil pollution which will affect the environment and the health of farmers. The papaya plant (Carica papaya L.) belongs to the Caricaceae family which has been widely used in traditional medicines. This research was carried out with the aim of determining the effect of administering C. papaya methanol extract on various biological aspects of Spodoptera frugiperda and to determine the compound content contained in the extract. This research will be carried out from June to August 2022 at the Agrotechnology Laboratory of the Tasikmalaya University of Perjuangan. The design used was a non-factorial Completely Randomized Design (CRD) with 5 treatment levels including 0%, 1%, 2%, 3% and 4% papaya extract. Each treatment was repeated 4 times so that there were 20 experimental units. The results of the study showed that 2% methanol extract of C. papaya leaves had a significant effect on inhibiting the growth of S. frugiperda from instar II to instar III but had no significant effect on the development of larvae from instar IV to imago. The research results showed that the methanol extract of C. papaya was not effective in inhibiting the formation of pupae and imago. Application of C. papaya leaf extract at a concentration of 1% can reduce the fecundity level of female imago of S. frugiperda but does not affect the fertility of the eggs produced.

Perbanyakan Fungi Mikoriza Arbuskula (FMA) Indigenous Pohon Mangga Lokal Indramayu Dari Berbagai Sumber Dan Dosis Inokulum Pada Tanaman Inang Pueraria javanica

Mango fruit (Mangifera indica L.) is one of the fruits that is popular with Indonesian people because it contains quite complete vitamins and is affordable. Development of mango cultivation in Indramayu is carried out throughout the year, but mango production fluctuates at each harvest time. One of the reasons for this is alternate bearing, namely the uncertain condition of the mango harvest every year due to internal or climatic factors. One effort that can be made to control this phenomenon is by using biological fertilizers such as Arbuscular Mycorrhizal Fungi (FMA). The host plant used for AMF propagation is Pueraria javanica because it is more resistant to humidity and low temperatures compared to sorghum. This research aims to obtain a source of AMF inoculum that is suitable for vegetative growth of Pueraria javanica and the highest number of spores and to obtain the right dose for the development of AMF and growth of the Pueraria javanica host. This research used a factorial Randomized Block Design with 2 factors where the first factor was AMF Inoculum Source which consisted of three types ( Lohbener Village mango trees, Jatisawit Village mango trees, Krasak Village mango trees). The second factor is the dose of the AMF inoculum source which consists of three levels of spore number (60 g, 80 g, 100 g). The results of the study showed that there was no interaction between the inoculum source and the dose on the growth of the host plant Pueraria javanica. The inoculum source of mango trees in Krasak Village had the best influence on the number of leaves of the host plant Pueraria javanica.

Sweet corn is a vegetable that people like. One of the problems in sweet corn cultivation is weeds, because it became competitors for getting nutrients, water, light, and hosts of disease. The usage of herbicides for weed control is widely used by farmers. This research aims to determine the effect of herbicides in weeds controlling on the physiology of sweet corn. The experimental design used is Randomized Block Design with 4 replications. Treatments tested included: no weed control; manual weeding; paraquat; glyphosate; paraquat, atrazine, mesotrione; glyphosate, atrazine, mesotrione; paraquat, atrazine, mesotrione, nicosulfuron; and glyphosate, atrazine, mesotrione, nicosulfuron. The variables observed are herbicide phototoxicity on corn plants, leaf area, leaf area index, net assimilation rate, plant growth rate, leaf chlorophyll content, and plant dry weight. Data were analyzed using ANOVA, if there are significant differences then continued with Duncan Multiple Range Test at 95% confidence level. The results of show that weed controlling using various herbicide active ingredients has effect on the physiology of sweet corn. The best treatment was shown by combination of paraquat, atrazine and mesotrione which shows the highest values at variables leaf area, leaf area index, plant dry weight, leaf chlorophyll content, net assimilation rate and plant growth rate of sweet corn.
