Abstract

The research aimed to study the influence of the application of NAA concentration, the addition of organic materials and a combination of both on media Knudson C towards the growth of orchid plantlet (♀) Dendrobium liniale >< (♂) Dendrobium biggibum. The purpose of using media Knudson C in culture in vitro is to optimize the growth of orchid plantlet Dendrobium liniale and Dendrobium biggibum. The experiments were carried out in the Laboratory of Plant Physiology and Biotechnology Faculty of Agriculture, Sebelas Maret University Surakarta. The research used Complete Randomized Design (CRD) with 2 treatment factors, factor I was the concentration of NAA (0 ppm, 1 ppm, 3 ppm and 5 ppm); and factor II was the organic materials (coconut water, banana, potatoes and sweet potatoes). In total there were 20 treatment combinations . Each combination was repeated four times. The results showed that the combination of sweet potato and NAA 5 ppm produced the following characteristics: the fastest root growth, most root length, and the largest number of leaves; while the combination of banana extracts and NAA 5 ppm produced a number of roots, the shoots appear most rapidly, and the highest number of shootsKeywords: genetic diversity; tissue culture; medium;

Abstract

Dendrobium nandia anindhita orchid is a favored hybrid of orchid because it flowers easyly and has high variety of flower colors. The aim of this study was to determine the effect of the application of Rhizoctonia mycorrhizaee on seedling Dendrobium hybrid orchids. It is expected that the seedling will have the characteristics of the Dendrobium orchid species. The research was carried out in a green house and laboratory of the Faculty of Agriculture, Tunas Pembangunan University. The design used was a completely randomized design with one variable and 25 seedling samples each. The results showed: (1) Microscopically, Rhizoctonia mycorrhizaee had the following characteristics: Fungal hyphae growing on PDA media were white, branches of Rhizoctonia mycorrhizaee hyphae formed elbows and had septa; (2) The application treatment of Rhizoctonia mycorrhizaee (M) had a significant effect on the parameters of plant height, number of leaves, number of roots, root length and plant fresh weight, treatment (M) had no significant effect on parameters of leaf length; (3) Morphological observations showed that the orchid plants that were applied to Rhizcotonia mycorrhizae had greener leaf colors, more leaves, and longer roots than those without Rhizcotonia mycorrhizae.

Abstract

Mentik Wangi is one of Indonesia's most popular rice germplasm sources due to its delicate, fluffy texture and arom aroma. Farmers switch to better varieties with high yields due to field challenges in cultivating fragrant rice. The plants are quite tall, harvest time is long, and yield is low; therefore farmers switch to superior varieties with high yields. The purpose of this research was to obtain information on how much yield of 14 mutant rice lines produce and to find mutant lines with short stems and high yields that could be developed to new varieties. The research was conducted at the Tegalgondo Rice Seed Garden Agricultural Land between June to October 2020. This study used a Completely Randomized Block Design (CRBD) with a single factor. Each treatment was repeated three times. The data obtained analyzed with analysis of variance and followed with Duncan Multiple Range Test at 5% level if any significant influences were obtained. The results of this research showed that 14 Mentik Wangi rice lines yields were ranging from 6.70 to  8.21 tons ha-1.Stems from 9 lines with high yields were M6-MW3-G10-14-2, M6-MW3- G12-1-17,  M6-MW3-G5-21-3,  M6-MW3-G5-21-14,  M6-MW3-G6-17-14-4,  M5-MW3-G6-20-9-16,  M6-MW3-G1-1-2  M5-MW3-G1-5-47,  M6-MW3-G6-10-9-26.  These lines were potential candidates for new high-yielding varieties, which would then considered to be evaluated for higher yields or multilocation tests before becoming an official new varieties.Keywords: mentik wangi; mutations; short stem; yield potential;

Abstract

Certified organic agriculture is a product that has competitiveness and opportunities for export. This study aims to determine and analyze the characteristics of farmers, the total cost and revenue and income of organic rice, ze the level of efficiency, and BEP (Break-Even Point) of certified organic rice farming. The sampling method used in this study was simple random sampling with a sample of 40 farmers calculated using the Slovin formula. The analysis used is: (1) the analysis of the mean score for the characteristics of the farmers, (2) the method of analyzing costs and revenues and farm income, and (3) the analysis of the efficiency of the farming business using the R/C (Return Cost Ratio) analysis method. The research location was determined purposively, namely Dlingo Village, Mojosongo District, Boyolali Regency. The results of the study concluded that: (1) The characteristics of organic farmers were that men are more involved than women, the age of organic farming business practicioners were above 50 years old, most of the farmers in Dlingo village have lived for more than 30 years, the main livelihood farmers in the agricultural sector. (2) Based on the total average cost for organic farming, the certified group has an average of Rp.20,495,000,- and The average revenue was Rp. 35,000,000,-. The income per planting season is Rp. 14.505.000,-. Organic certified farmer groups get an R/C ratio value of 1.7;  the R/C > 1 means that farming with certified organic systems is efficient. Rice farming with a certified organic system is profitable because the BEP value of production volume was 2,927 < farmers' production, while the BEP value for production price was 4,099 < selling price at the farmer level.Keywords: organic rice; income; efficiency;

Abstract

Black rice contains higher levels of anthocyanin, fiber, and protein compared to local white rice. The price of black rice is higher compared to local white rice, it is one of prove that black rice has functional and economical values. The main obstacles in the cultivation of black rice are the long harvest age, high plant height, and lack of productivity. One way that can be applied to overcome this dissadvantageis with the utilization of gamma ray irradiation. The purpose of this research is to get the early-season rice, short stem, and higher productivity. This research was conducted in Tempel, Gatak, Sukoharjo District, by planting M3 seed (gamma ray irradiation of 300 Gray dosage on M2). The results of black rice from gamma ray irradiation of 300 gray dosage are M-CI-03-239, M-CI-03-244, M-CI-03-246, M-CI-03-346, M- CI-03-350, M-CI-03-234, M-CI-03-346, M-CI-03-350, M-CI-03-250, M-CI- 03-346, M-CI-03-CI-03-262, M-CI-03-265, M-CI-03-270, M-CI-03-283, and M-CI-03-311 with the agronomical properties of early age, i.e 2 weeks faster (64 days) with control (80 days). There are 125 short-postured plants of gamma ray irradiation result with  99.2% percentage. There are 12 individual plants in the M3 strain (M-CI-03-240, M-CI-03-251, and M-CI-03-261) of gamma ray irradiation with the maturation category, short stems, and high productivity compared with control. The difference of productivity of irradiated crops with control is 57,91%.

Abstract

This study aims at identifying the use of organic and anorganic mulch of the zucchini plants appropriate elephant manure inyorder to obtain optimal growth and yield. The study has been on, Boyolali Regency with an altitude of 170 m above sea level.Thishresearch method is an experiment using a factorial treatment Randomized Completed Block Design (RCBD) with 3 times. There are two kinds of treatment under the study that is dose of elephant manure and kind of  mulch, elephant manure dose treatment factor (G), there are 3 levels of treatment, namely (G1) Elephant manure dose 5 tons / ha, (G2) Elephant manure dose 10 tons / ha, (G3) The dose of elephant manure is 15 tons / ha, the treatment factor is mulch (M), there are 3 types of treatment, namely (M0) without mulch (M1) Silver mulch (M2) mulch straw.Therresults of this study show that treatment for the dose of elephant manure (G) showed no significant different to all observed parameters, the mulch type treatment (M) show highly significant to fruituweightoperlplantmand fruit diameter, show significant to fruit length, and biomassyfreshpweight per plant, while biomasydry weight per plant showed no significant effect. The interaction between elephant manure dose and mulch type (GxM) showed no significant to all observed parameters. The highest fruit weight yield was (478.84 g) in the treatment combination and the lowest was obtained in the treatment combination (253.05 g).
