Abstract

Cucumber (Cucumis sativus L.) is type of fruit vegetable that is widely consumed by the people of Indonesia. Cucumber cultivation is still not intensive, that is many farmers do not do pruning and use inappropriate doses of fertilizers, so it is necessary to improve cultivation techniques through proper pruning and fertilization. This purpose of this study is to determine the effect of pruning time and dose of potassium fertilizers on cucumber crop yields. The research was carried out from January 9 to March 18, 2022 in Ngencek, Kalikuto, Grabag, Magelang, with an altitude of 510 m asl. The method of the research was factorial arranged in a completely randomized complete block design (RCBD) with two factors. The first factor is pruning time of 21 hst and 28 hst. The second factor is the dose of potassium fertilizers consisting of 0 kg/ha, 80 kg/ha, 160 kg/ha, and 240 kg/ha. The results showed that the pruning time of 21 days after planting had a significant effect on the flowering age of cucumber plants. Different doses of potassium fertilizers had no effect on plant length, flowering age, number of fruit per plant, weight per fruit, fruit weight per plant, fruit length, fruit diameter, and fruit volume. There was no interaction between pruning time and the dose of potassium fertilizers given.Keywords: Cucumis sativus L., doses, potassium fertilizers, pruning time.

Abstract

Grafted cutting is a method for vegetative Ninel vine propagation. The purpose of thisstudy was to ascertain the impact of several grapevine rootstock species and planting media types on the development of Ninel grape seeds propagated through grafted cutting. The study was conducted in Kebonrejo village, Salaman district, Magelang regency (290 m asl) from April 2 to May 24, 2022, using a randomized complete block design (RCBD) consist of 2 treatment factors with 3 blocks. The rootstock species of grapevines, such us Vitis vinifera, Vitis labrusca, and Vitis riparia are the first factor. Planting media types classified as second factor include blends of topsoil + husk charcoal, topsoil + cocopeat, and topsoil + sand. The datas were anylized by Anova and continued with the Least Significant Difference (LSD) test and Duncan's Multiple Range Test (DMRT). The findings demonstrated that the grafted cutting method with rootstock from the Vitis riparia species on the scion of Vitis vinifera of the Ninel variety had the maximum yield in terms of shoot length, shoot diameter, leaf area and grafting success. Topsoil + husk charcoal and topsoil + sand were the types of planting medium that had the greatest effectiveness at grafted cutting.Keywords : planting medium, rootstock species, grafted cutting, Ninel vine

Abstract

ABSTRACTTomatoes is one type of fruit vegetables annuals that may be planted in the lowlands and high. The coconut water as a natural growth regulator by concentration of the certain and long immersion could increase yield of tomatoes. Research on the influence the coconut water and long immersion cuttings of the results of tomato plants have been conducted by 2022 on 14 July until 20 September 2022. Research carried out in Bojong Hamlet, Maduretno Village, Kaliangkrik District, Magelang Regency with an altitude place 763 m above sea level. Research methodology used experiment factorials ( 4x3 ) arranged in the complete random design ( rakl ) two factors in treatment by three as a block. The first factor was the concentration of coconut water, namely 25%, 50%, 75% and 100%. The second factor was long immersion cuttings, namely 4 hours, 8 hours and 12 hours. Date were analyzed using variance and tested using orthogonal polynomials. The concentration of 25% coconut water gave the fastest age of flowering and the concentration of 100% coconut water produced the largest volume of fruit. Long immersion cuttings offer the same result height of plant, age of flowering, number of fruit per plant, weight of fruit per plant, volume of fruit and percentage of plants attacked by the virus. The concentration and long immersion cuttings gave a same result to the all parameters observation.Keywords: coconut water, concentration, long immersion, tomato.

Abstract

Research on the response of wheat plants to the application of mycorrhizae and K fertilizer was carried out from October 16, 2021 to January 25, 2022. The study was conducted in Selopampang Village, Selopampang District, Temanggung Regency with an altitude of 670 m above sea level. The research method used a factorial experiment (4 x 3) arranged in a Completely Randomized Block Design (RAKL) with two treatment factors and repeated three times. The first factor was the dose of mycorrhizae 2,5 g/plant, 5 g/plant, 7,5 g/plant and 10 g/plant. The second factor was the dose of potassium 17,5 kg/ha, 35 kg/ha and 52,5 kg/ha. Data were analyzed by means of variance. The influential results were further tested using orthogonal polynomials. The results showed that the high of mycorrhizae dose increase the dry weight of seed per clump. Potassium fertilizer with a dose of 52,5 kg/ha gave the highest yield on  the dry weight of seed per clump. Mycorrhizae 10 g/plant and K fertilizer 52,5 kg/ gave the highest yield on the dry weight of seed per clump.
