Abstract

Tomatoes are important vegetable commodities and have high nutritional value. Until now, tomato productivity was still quite low at 16.09 - 18.63 tonnes/ha from 2015 to 2019 when compared to its potential which could reach 20-30 tonnes/ha. One of the ways to increase the productivity of tomato plants is to improve cultivation techniques, especially the use of suitable planting media and pest control by utilizing natural materials. The composition of the media that was suitable for tomato plants needs to be known to produce high-quality and high-yielding tomatoes. Bio-pesticide application using several plants with the appropriate dosage can be an alternative to reduce the use of chemicals. This study aimed to determine the composition of the plant media and the effectiveness of biopesticides to increase the production of tomato plants. The study used Completely Randomized Design (CRD) two factors, where the first factor is the composition of the growing media and the second factor is the dosage of vegetable biopesticides. The first factor is the composition of the growing media consisting of 4 levels, namely K0 (without bokashi), K1 (Soil: Bokashi = 11: 1 (W/W) per polybag, K2 (Soil: Bokashi = 5: 1 (W/W) per polybag), K3 (Soil: Bokashi = 3: 1 (W/W) per polybag. The second factor is the dosage of vegetable biopesticides consisting of 4 levels, namely A0 (control), A1 (20 ml per polybag), A2 (40 ml per polybag), A3 (60 ml per polybag). Each treatment consisted of 4 levels of treatment and was repeated 4 times so that there are 64 experimental units. The data were analyzed using analysis of variance, and the real effect then tested further using Least Significance Different at 5% level. The results showed that there was an interaction between the treatment of the composition of the planting medium and the biopesticide on the parameters of plant height, number of leaves, leaf area, number of fruits, fruit weight, and production. The composition of the soil growing media composition: bokashi (5:1) and 40 ml biopesticide (K2B2) produced the highest number of fruit which was 255.53 fruit, the largest fruit weight was 7.67 kg per plant and produce 10.22 tonnes/ha. The use of biopesticides is effectively applied to tomato plants so that it can reduce the number of plants affected by fusarium wilt disease. the ones with the highest number of healthy plants were in A2 treatment with a pesticide dose of 40 ml per plant at 81.25%.

Abstract

The regular application of synthetic fertilizers in every rice planting season has the potency to be a pollutant on the environment. Therefore, it is necessary to apply a rice cultivation system that is more environmentally friendly by utilizing organic fertilizers and biological agents as substitutes for synthetic fertilizers with the System of Rice Intensification (SRI) method. The objective of this study was to determine the growth and yield of rice by the SRI method during the dry season with the application of organic fertilizers and biofertilizers. The study was conducted in Banjaranyar Village, Sokaraja District, Banyumas Regency. The study used a divided plot design with main plots of rice varieties namely Situ Bagendit and IR 64, and types of fertilizers, namely NPK fertilizer (urea, SP36, KCl), organic fertilizers, and biofertilizer as subplots with three replications. The variables observed included plant height, number of productive tillers, leaf area, shoot dry weight, panicle length, number of filled grains per hill, grain weight per hill, effective grain weight per plot, 1000 grains weight, grain weight per hectare, and harvest index. The data were analyzed by using the F test and if it showed a significant difference, then continued with the LSD test with a confidence level of 95% to determine the effect of each treatment tested on the observed variables. The results showed that the Situ Bagendit variety gained a higher number of productive tillers and larger leaf area than the IR 64 variety, but both varieties gave equivalent yields in yield components ranged 1.5-1.6 t/ha. Organic fertilizers and biofertilizers were able to reduce the use of synthetic fertilizers due to provide equivalent yield in both varieties.

Abstract

The kidney bean plants in East Nusa Tenggara (NTT) are generally cultivated in the highlands, whereas the areas in NTT are dominated by lowlands with extensive dryland agro-climatic conditions. Kidney beans are suitable for planting in areas with wet climates with varying altitudes. The suitable altitude is 1000-1500 hasl. However, it turns out that several research results showed that kidney beans can be grown in dryland or lowland ricefields with low production. During the growth of kidney bean plants, apart from the micro-climate that affects plant growth, the elements of production field management are also very important to support plant growth, such as balanced nutrient management. One of the technologies studied to increase production is NPK Phonska fertilization and Amazing Bio Growth biostimulant. The purpose of this study was to examine the dosage of NPK Phonska fertilizer and the best Amazing Bio Growth biostimulant concentration on the growth and yield of Inerie kidney bean seeds in the lowlands. The factors studied were the NPK Phonska (N) dose consisting of 3 levels, namely: N1: 300 kg / ha; N2: 250 kg / ha; N3: 200 kg / ha. And the concentration factor of ABG (B) biostimulant consisted of 4 levels, namely: B1: 2 cc/liter of water; B2: 4 cc/liter of water; B3: 6 cc/liter of water; and B4: 8 cc/liter of water. The results of the study informed that the dose of 250 kg/ha NPK Phonska gave the best 2 MST plant height (26.20 cm), 2 and 4 WAP stem diameter (3.64 mm and 5.85 mm), and the number of filled pods (15.52). pod). The concentration of ABG biostimulant 8 ml / l of water gave the best 4 WAP plant diameter (5.61 mm). The interaction between the NPK Phonska dose of 250 kg/ha and the concentration of ABG biostimulant 6 ml / l of water gave the best response to the number of filled pods (16.50), number of grains (48.63 grains), and grain weight (18.30 g).

Abstract

Coconut Kopyor is an abnormal fruit, the ordinary coconut flesh is attached to the shell and separated from coconut water while Coconut Kopyor, fruit flesh is not attached to the shell but is mixed with coconut water. Kopyor coconut cannot be used as a seed (seed). The growth of kopyor coconut embryos can only be done in a laboratory with embryo culture technology. Embryo culture is the only way to produce true to type coconut kopyor seeds that can produce 80% kopyor coconut in one kopyor coconut plant, kopyor coconut seedlings produced can support government programs in increasing the productivity of kopyor coconut through the provision of quality seeds. Research on kopyor coconut embryo culture was carried out at the Laboratory of Tissue Culture at Lampung State Polytechnic. The experiment was carried out using a RAL, with 15 treatment combinations of BA media formulations (0, 2, and 4) with coconut water (0 ml / l, 100, 150, 200, 250 ml / l). The observed variables were the percentage of embryos sprouting, when the shoot appeared, shoot height, number of roots, and number of leaves. The results showed that the use of BA 4 mg / l without the addition of coconut water increased the percentage of sprouts, faster time for shoots, and highest shoot height.
