Abstract

ABSTRACT  The purpose of the research was to study the effect of various sprouts extracts and various types of manure on the composition of the growing media on the growth of Mulberry cuttings. The research was carried out at Screen House in Kalisidi Village, West Ungaran, Semarang Regency and Diponegoro University Physiology and Plant Breeding laboratory. The research design used was a Completely Randomized Design (CRD) 5x3 factorial pattern and repeated 3 times. The first factor was soaking cuttings on sprout extract, without treatment (K0), giving synthetic growth regulator (K1), soaking soybean sprout extract (K2), soaking peanut sprout extract (K3), soaking mung bean sprout extract (K4). The second factor is the type of manure in the composition of the growing media with 3 types of fertilizers namely cow manure (P1), chicken manure (P2), goat manure (P3). The results showed that the treatment of soaking cuttings with sprout extract had a significant effect on the number of roots, and the treatment of manure types on the composition of the growing media had a significant effect on all parameters of observation.Keywords: sprouts extract, root number, planting media, Mulberry, cutting. ABSTRAK  Tujuan dari penelitian adalah untuk mengkaji pengaruh pemberian berbagai ekstrak kecambah dan berbagai jenis pupuk kandang pada komposisi media tanam terhadap pertumbuhan vegetatif stek murbei.

Abstract

ABSTRACT  The purpose of this research was to to examine the interaction effect between the different concentration of onion extract and immersion time on growth responsesofIxora coccinea cutting. This research used a completely randomized factorial design. The first factor was the concentration of onion extract (K0 = 0%; K1 = 80%; K2 = 90%; and K3 = 100%). The second factor was the immersion time of onion extract (P1 = 3 hours; P2 = 4 hours; and P3 = 5 hours). The parameters were number of shoots, shoot length, shoot time appear, longest root length, primary roots, wet root weight, dry root weight, wet shoot weight, and dry shoot weight. The data were analyzed by variance analysis and continued by Duncan's Multiple Range Test. The results showed that the different concentration of onion extract increased number of shoots, shoot length, shoot time appear, longest root length, primary roots, wet root weight, dry root weight, fresh shoot weight, and dry shoot weight. Submersion period take effect to number of shoots, longest root length, primary roots, wet root weight, adn dry root weight, but there was no effect to shoot time appear, fresh shoot weight, dry shoot weight, and shoot length. Key Words: Cutting, Growth Response, Onion Extract, Ixora coccinea ABSTRAK  Penelitian ini bertujuan untuk mengkaji pengaruh interaksi antara perbedaan dosis ekstrak bawang merah dan lama perendaman terhadap respon pertumbuhan stek tanaman Soka Mini. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola faktorial. Faktor pertama adalah konsentrasi ekstrak bawang merah (K0 = 0% K1 = 80% K2 = 90% dan K3 = 100%). Faktor kedua adalah lama perendaman masing-masing bahan (P1 = 3 jam P2 = 4 jam dan P3 = 5 jam). Variabel yang diamati meliputi jumlah tunas, panjang tunas, waktu muncul tunas, panjang akar terpanjang, banyak akar primer, berat basah akar, berat kering akar, berat basah tunas, dan berat kering tunas. Data yang diperoleh dianalisis dengan anova dan dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan pemberian konsentrasi yang berbeda dapat meningkatkan jumlah tunas, panjang tunas, waktu muncul tunas, panjang akar terpanjang, banyak akar primer, berat basah akar, berat kering akar, berat basah tunas, dan berat kering tunas. Lama perendaman berpengaruh terhadap jumlah tunas, panjang akar terpanjang, banyak akar primer, berat basah akar, dan berat kering akar, namun tidak berpengaruh pada waktu muncul tunas, berat basah tunas, berat kering tunas, dan panjang tunas.

Abstract

ABSTRACT  This research aimed to identify the effect of cow urine concentration on the growth and yield of red betel simplicia (Piper crocatum) on different composition of planting media. The research used 3 x 5 factorials experiment with Completely Randomized Design (CRD) consisting of 3 replications. The main factor is composition of planting media (soil:husk charcoal) based on volume (M) which consists of 3 levels treatment namely M1= 1:3, M2 = 1:1, M3 = 3:1. The second factor is the concentration of cow urine consist of 5 levels treatment namely K0 = 0%, K1 = 7,5%, K2 = 15%, K3 = 22,5% dan K4 = 30%. The observed parameters were shoot length, number of leave, the wet weight shoot, the dry weight shoot, and number of roots. The result showed that there was an interaction between the treatment of composition of the planting media and concentration of cow urine had a significant effect (P<0,05) on the shoot length, number of leaves, the wet weight shoot, and number of roots. Treatment of cow urine concentration of 22,5% gave the best result on shoot length, number of leaves, the wet weight shoot, the dry weight shoot and number of roots. Treatment composition of soil:husk charcoal (1:1) and 22,5% cow urine concentration gave the best results onshoot length, number of leaves, and wet weight shoot.
