Plant media and nutrition are key faktors in plant growth, including pakchoy microgreens. This research aims to determine the effect of the type of planting media and the dose of cow urine liquid organic fertilizer on the growth of pachoy microgreens. This research was structured using a factorial Randomized Group Design (RGD). The first factor is that the planting media consists of 3 levels, namely: cocopeat (M1), husk charcoal (M2) and cocopeat + husk charcoal (M3). The second factor is the dose of liquid organic fertilizer from cow urine cinsisting of 2 levels, namely a doses of 25 ml/L (D1), 50 ml/L (D2) and a control using water (D0). The research results show that media treatment and liquid organic fertilizer had a significant effect on the fresh weight to microgreens, but had No. significant effect on germination time, emergence of cotyledons and 100% germination. The use of cocopeat media without the applicaation of liquid organic ferlitizwer gave a better response compared to the application of liquid organic fertilizer. Husk charcoal medai, mixed media of husk charcoal and cocopeat with the aplication of 25 ml/L liquid organic fertilizer gave a better response than without the application of liquid organic fertilizer. The use of cocopeat media shoud not be accompanied by the application of liquid organic fertilizer.

Pakcoy plants need nutrients like POC and organic growing media such as charcoal, cocopeat and sawdust to grow well. This research aims to determine the response of pakcoy plants (Brassica rapa L.) to various planting media with bamboo shoot POC at different concentrations, as well as the interaction between the two. This research was structured using a randomized block design (RAK) in factorial form, with the first factor being planting media using husk charcoal (M1), sawdust (M2) and cocopeat (M3), while the second factor was POC treatment which consisted of 4 doses, namely; 0 ml POC/100 ml water (D0), 20 ml POC/100 ml water (D1), 40 ml POC/100 ml water (D2), and 60 ml POC/100ml water (D3). Pakcoy plant variables observed were plant height, number of leaves, leaf area index, fresh weight of stover, wet weight of roots, and root length. The data analysis used was analysis of variance (ANOVA) with a confidence level of 95% (α 0.05) and α 0.01). If p ≥ α 0.05, then the BNJ 0.05 further test is carried out (5% confidence level). The results of the study showed that the interaction between the planting medium used and the POC dose of bamboo shoots only had a significant effect on the root length of pak choy plants in the combination of sawdust planting medium and POC 60 ml/100 ml water (M3D3), while the other parameters did not have a real impact. Partially, 99% of the best response of pakchoy plants was using charcoal husk planting medium (M1), while using POC bamboo shoots showed the best response was shown when using a POC dose of 60 ml/100 ml water.

Sengon (Falcataria moluccana Miq.) is a pioneer tree species that is widely developed in industrial plantation forests and community forests because of its fast growing species. The properties of sengon seeds which are classified as orthodox can decrease their viability and vigor during storage. The colchicine hormone is expected to increase the acceleration of plant growth so that it can increase the success of sengon seed growth. The aim of this research was to see the effect of colchicine treatment on the accelerated growth of sengon seeds. This research was carried out using a Completely Randomized Design (CRD) with one factor, namely colchicine concentration. The concentrations used are: 0 (control), 0.5 ppm, 1.0 ppm, 1.5 ppm, 2.0 ppm. The effect of the treatment was seen through variance testing using SAS 9.0 portable software. The variance results showed that soaking in colchicine solution had a very significant effect on the maximum growth potential, germination capacity and germination value, while the colchicine solution soaking treatment had no real effect on growth speed.

Rhizoctonia solani Khun, is one of the fungi that causes important diseases in rice plants which can reduce rice production with a severity level of 6-52%. The aim of this research is to analyze the effectiveness of fungicide active ingredients in suppressing the development of R. solani disease. The research was carried out in March-July 2022. The method used was a Completely Randomized Design (CRD), in vitro testing was carried out with 10 treatments and 10 replications and in vivo testing was carried out in 9 treatments with 3 replications. Active fungicide treatments used: T1: Propinab 70%, T2: Trifloxystrobin 25% + Tebuconazole 50%, T3: Difenoconazole 250 g/l, T4: Azoxystrobin 200 g + Difenoconazole 125 g, T5: Difenoconazole 250 g, T6: Azoxystrobin 200 g + Difenoconazole 125 g/l, T7: Azoxystrobin 250 g/l + Difenoconazole 150 g/l, T8: Propiconazole 125% + Tricyclazole 400%, T9: Piraclostrobin 133 g/l + Epoxiconazole 50 g/l and T0= control without treatment. The parameters observed were calculating the mycelium diameter at 2 days after application (HSA) up to 14, calculating the percentage of attacks at 7 HSA1, 7 HSA2 and 14 HSA3. The results of the efficacy test showed that several fungicide active ingredients in controlling rice sheath blight (R. solani) in rice showed significant differences between treatments of fungicide active ingredients on the development of the pathogen. T2 active ingredient treatment: Trifloxystrobin 25% + Tebuconazole 50% provides the best efficacy test results in vitro and in vivo.

One of the problems with companies engaged in seed production is that many seeds produced are not sold quickly and expire, resulting in a decrease in physiological quality. The purpose of this study was to determine the increase in the physiological quality and growth of expired cayenne pepper (Capsicum frutescens) seeds through the invigoration technique using young corn extract (Zea mays). The research was conducted using the Non-Factorial Completely Randomized Design (CRD) with the concentration of young corn extract (K) as the treatment factor. Data were analyzed using ANOVA and followed by DMRT level of 5%. The K factor consists of 5 levels; K0 (without soaking in young corn extract), K1 (20% of young corn extract), K2 (25% of young corn extract), K3 (30% of young corn extract), and K4 (35% of young corn extract ). The results showed that the use of young corn extract for invigoration of expired cayenne pepper seed had a significantly different effect on the parameters of growth synchrony and vigor index, and had a very significant effect on the parameters of germination power, maximum growth potential, and growth speed, compared to the control treatment. These results indicate that young corn extract is capable of acting as a bio-invigorator in improving the physiological quality of expired seeds

Trichoderma sp and cow manure as biofertilation that supports the growth and production of horticultural and food crops. The aim of the research is to determine the application time of Trichoderma sp on purple eggplant plants, to determine the interaction between the Trichoderma sp fungus and which dose of manure provides the best growth and production on purple eggplant plants. This research method was prepared based on a split plot design (SPD), with 12 treatment combinations, each treatment repeated 3 times so that there were 36 experimental units. The main plot is the dose of cow manure (p), consisting of 3 levels, namely, p1 (cow manure dose 500 g/polybag), p2 (cow manure dose 750 g/polybag), p3 (cow manure dose 1000 g/ polybag). The subplot is the application time of Trichoderma sp (a), consisting of 4 application times, namely, t0 (without Trichoderma sp), t1 (1 week before planting), t2 (at planting time), t3 (1 week after planting). The treatment of Trichoderma sp application time has no effect on the growth and production of purple eggplant plants due to the dose of Trichoderma sp is not optimal, giving a dose of manure 1000g.polybag is more effective than 750g.polybag and 500g.polybag on production (length and weight of fruit/plant) purple eggplant. The interaction between the dose of manure 500g.polybag with Trichoderma sp application time 1 week before planting gave the best effect on the growth of crown weight, root weight and production (length of fruit/plant) of purple eggplant

The increase in coffee production in Indonesia has resulted in an increase in by products in the form of coffee skin waste, which can be processed into organic fertilizer. The purpose of this study was to determine the formulation of organic fertilizer that gives the best effect on the growth of robusta coffee seedlings. This study used a Randomized Group Design (RDB) with the treatment of various formulations of coffee skin waste organic fertilizer with the addition of nitrogen producing plants, namely without coffee skin waste organic fertilizer (soil) or control (P0), coffee skin waste organic fertilizer without the addition of nitrogen-producing plants (P1), coffee skin waste organic fertilizer with the addition of babadotan plants (P2), coffee skin waste organic fertilizer with the addition of mucuna plants (P3) and coffee skin waste organic fertilizer with the addition of lamtoro plants (P4). The dose given per polybag was 300 grams/polybag. The nutrient content of the organic fertilizer formulation with the addition of lamtoro plants produced the highest nutrient content compared to the addition of mucuna and babadotan leaves, namely N by 1.88%, P by 0.50% and K by 3.14%. In the observed variables, namely plant height and stem diameter, the formulation treatment with the addition of lamtoro produced the highest plant height and largest plant diameter, but was not significantly different from the other treatments. The organic fertilizer treatment with the addition of lamtoro plants also produced the highest number of leaves and was significantly different from the soil treatment (control) and treatment with the addition of babadotan plants, but not significantly different from the formulation treatment with the addition of mucuna and treatment without the addition of nitrogen producing plants.
