Combination of Urea 400 kg/ha with chicken manure 20 ton/ha gave the highestyield in sweet corn with the the results of 9,153 kg/4,5m2 or equal to 20,340 tonnes/ha compared with a combination of urea 100 kg/ha with manure chicken 10 tons/ha is 7,321 kg/4,5m2, equivalent to 16,269 tonnes/ha, meaning that the difference has a 4,071 ton/ha (20,01%)

Aplikasi Kompos Tandan Kosong Kelapa Sawit dan Mikoriza Arbuskula untuk Meningkatkan Pertumbuhan Bibit Manggis (Garcinia Mangostana L.)

Abstrac Mangosteen (Garcinia mangostana L.) is one of the most Indonesian favored fruit, because the ripe fruit (ripe) has a distinctive taste, sweet, sour and fresh. The main problem encountered in the cultivation of mangosteen is to provide theseeds. Weak mangosteen plant roots decrease growth level. This study aims to determine the interaction of palm oil empty bunches compost with Arbuscular Mycorrhiza on the seed growth of mangosteen and get the best dose. This research was conductet AgricultureFaculty, University of Riau campus Bina Widya Tampan, Pekanbaru lastedOctober 2012 until January 2013. The results of shows that by using TKKS compost with a dose of 150 g/polybag and the use of mycorrhizae 15g/polybag is better than giving 150 g/polybag and mhycorrizhal 20 g/polybag because the results are not significantly different. To get the combination use of empty fruit bunches of oil palm compost and mycorrhizal needs to be done in a long time , to get more tangible results

Pemberian Pupuk Tricho Kompos Jerami Jagung terhadap Pertumbuhan dan Produksi Bawang Merah (Allium Ascalonicum L.)

Onion is one of the important commodity in Indonesia, onion is also a much-needed spice vegetables society. Onion crop growth is affected by the level of fertility of growing media and other environmental factors. Fertilization is vital to the growth and yield of onion for proper fertilization can increase the fertility of growing media. One effort to improve soil fertility mineral that is with organic matter. Organic materials that can be used is corn straw which has been decomposed with the help of the fungus Trichoderma sp. This study was conducted over three months from December 2014 to February 2015. The study was conducted experimentally with 5 treatment using a Completely Randomized Design (CRD), each treatment was repeated 4 times so that there are 20 experimental units. , Parameters measured were the number of leaves, number of tubers, tuber dry weight of the shelf, and wrap the tubers. Data were analyzed statistically and followed by Duncan's test at 5% level. The results showed that administration of tricho compost with a dose of 15 tonnes / ha gave the best results on the number of leaves, number of tubers and tuber dry weight of the shelf

Pertumbuhan Bibit Buah Naga (Hylocereus Costaricensis) dengan Perbedaan Panjang Stek dan Konsentrasi Zat Pengatur Tumbuh

Dragon fruit (Hylocereus costaricensis) is one of fruit trees that grow well in Indonesia, so it has a great chance to be developed. These opportunities must be balanced with the supply of seed. Cuttings material and Growth Regulator Substance (GRS) concentration a factor that must be considered in the cultivation of seedlings because it will affect the growth of it in the field. The research was conducted at dragon fruit plantation Tameran village Bengkalis regency. The time used in this research lasted from August to December 2012. The design used was a Completely Randomized Design (CRD) 3 x 3 factorial with 3 replication. The first factor is the length cuttings, which is 20 cm, 25 cm and 30 cm. While the second factor is the GRS concentration, which is 6 g/10 ml, 9 g/10 ml and 12 g/10 ml. The parameters measured were the time appeared root, root length, number of roots, root volume, time appeared shoot, shoot length, number of shoots seedling fresh weight gain and dry weight of seedlings. Data were analyzed statistically using analysis of variance (ANOVA) and further tested by further testing (DNMRT) level of 5%. Results shows of the best dragon fruit seedlings growing on a combination between the 30 cm long cuttings with 9g/10 ml GRS concentration
