Abstract

Leonardite is a common mineral that contains a lot of organic matter. It may have a beneficial influence on plant growth and nutritional content. The objective of the present study was to determine the effect of four different leonardite doses (0, 20, 35, and 50 g kg-1), three different phosphor rates (0, 50, 100, and 150 mg kg-1P), on plant growth, and nutrient uptake of Cucumber (Cucumis sativusL.). plants. The experiment was conducted in a plastic house. Increasing the leonardite dose statistically increased the concentrations of N, P, K, Mg, Cu, and Mn in the cucumber leaves, but Zn content (34.711 a) mg kg-1of the leaves was significantly higher only with the (20 gm) of leonardite. The highest phosphor application (150 mg kg-1) increased leaf N, P, K, Ca, Mg, and Mn concentrations compared with the other three doses and also the leaf Zn levels statistically did not increase as the P applications increased from (control to 150 mg kg-1). Based on the number of fruits per plant, the best interaction among leonardite doses and phosphor rate were a combination of the (35gm×100 mg kg-1) increasing the numbers of cucumber per plant (48.000a).

Abstract

Jatropha is a pioneer plant that can easily grow even on marginal lands and has high potential as an oil-producing plant for renewable fuels. This plant is an annual plant that can grow until the age of 50 years, in the form of a bush and begins to produce at 6 months after planting with a productivity varying from 0.5 to 12 tons/ha/year with an oil yield of 25-30% and maximum production will be achieved after planting. Plants 4-6 years old. Jatropha has the potential to become an alternative energy source and become a biofuel with renewable energy sourcesor renewable green energy; in addition to other benefits in traditional medicine for various types of diseases. The purpose of this study was to determine the increase in the initial growth of Jatropha cuttings by giving organic growth regulators. Based on the results of the study, it can be concluded as follows: There was no significant interaction in the treatment combination between the concentration of organic growth regulators and the factor of internode location on all dependent variables observed in the early growth of Jatropha stem cuttings. The internode location factor showed a significant effect on the variable number of leaves, shoot length, root length, number of roots, root wet weight, root dry weight, and the location of the 12th internode (R2) gave better results than the 10th internode location. (R1). The concentration factor of organic growth regulators also showed a significant effect on the variables of leaf number, shoot length, root length, root number, root wet weight, root dry weight and K2 treatment (5 ml per liter of water) gave better and more efficient results. compared to other treatments.

Abstract

Alcohol factory waste which still contains a number of nutrients when enriched with manure is good enough to increase the growth and yield of chili. This research was conducted in Jengglong, Jatisobo Village, Polokarto District, Sukoharjo Regency which took place from September 2019 to January 2020. This study used a completely randomized design with two factors and three replications. The first factor consists of 3 levels of Liquid Organic Fertilizer: waste alcohol + EM4, waste alcohol + EM4 + goat manure, alcohol waste + EM4 + a combination of 3 manure (chicken, goat, cow). The second factor dosage of liquid organic fertilizer consists of 4 levels: 0, 1000, 2000, 3000 l/ha. The results of the study showed that the kind and dosage of liquid organic fertilizer enriched with manure did not significantly affect the growth and yield of chili, but the interaction of the two treatments had a significant effect on the yield of chili. The highest weight of red chili was obtained in the treatment of waste alcohol + EM4 + a combination of 3 manure (chicken, goat, cow) with a dose of 3000 l/ha. In conclusion, the use of alcohol waste for fertilization, especially chili plants, should be combined with manure in order to obtain maximum results. The implication of this research is that for fertilizing chili plants, it is better to use alcohol waste, EM4 and a combination of chicken, goat and cow manure at a dosage of 3000 l/ha.
