Pertumbuhan dan Produksi Beberapa Galur dan Varietas Tomat (Lycopersicum Esculentum Mill.) di Dataran Rendah

One of exfort to increase tomato productivity is considering the cultivation aspect and using high yield variety which can adapt finely on it recent invironment. The other ways to increase the productivity is though plant breeding whis is the aim is to find and create new variety from certain population. The research aim to get tomatoes genotype that have fine growth and productivity at the low land which eventually can be created as new variety. The research held for 5 months. The research arranged experimentally using Randomined Block Design (RBD) consist of 24 plant and 10 samples. Treatment are Ratna Variety, Intan Variety, IPB T3-8-10, IPB T57-3, IPB T65-6-2012 and IPB T30-4-4. Parameters are plant height, stim girth, fruith longth, flowering date, harvesting date, fruit girth, weight per fruit and total yield per plant. Result shows that genotype of IPB T3-8-10 and IPB T-30-44 Had yield better than Ratna variety and Intan. A highest total of fruit weight per plant on genotype IPB T3-8-10 (1144 g), IPB T3-44 (796 g), IPB T57-3 (734.6 g) and IPB T65-6-2012 (605.6 g)

Pengaruh Pemberian Urine Sapi Dan Pupuk Npk Terhadap Komponen Produksi Tanaman Jagung Manis(zea Mayssaccharata Sturt)di Lahan Gambut

This study aimed to determine the effect of cow urine and NPK fertilizers, as well as getting the best dose on production component of sweet corn on peatlands. The research was conducted on peat types sapric in Experimental Farm, Faculty of Agriculture Rimbo Panjang TambangDistrict of Kampar Regency and conducted over three months starting in December 2015 to March 2016. The study was conducted using a factorial RAL consisting of two factors with the first factor is giving of cow urine U1: cow urine concentration of 150 ml/l, U2: cow urine concentration of 300 ml/l, U3: cow urine concentration of 450 ml/l and U4: cow urine concentration of 600 ml/l. The second factor is the NPK fertilizer is P0: without fertilizer NPK, P1: award NPK 150 kg/ha and P2: award NPK 300 kg/ha. Data were analyzed statistically using analysis of variance followed by Duncan's multiple range test at 5% level. Parameters measured were plant growth rate, production per plot, weight per cob without husk, cob without husk lengthand diameter cob without husk.The results showed interaction NPK fertilizer of cow urine and cow urine as well as single factor effect is not real to each parameter of observation. Giving a single factor NPK showed an increased rate of plant growth, production per plot, weight per cob without husk, without husk cob lengthand cob diameter without husk. Increased production of sweet corn is highest at a dose of 300 ml of cow urine treatment with NPK fertilizer 150 kg/ha of 6,53 kg/5,25 m2 (equivalent to 5,0 tons/ha), increased 83% compared with no fertilizer NPK and 150 ml cow urine

Pemberian Abu Sekam Padi Dengan Pupuk Npk Terhadap Pertumbuhan Dan Produksi Tanaman Jagung Manis (Zea Mays Saccharata Sturt) Pada Tanah Gambut

This research aimed to study the giving effect of rice husk ash with good NPK fertilizer towards the growth and production of sweet corn in peat soil. This experiment was conducted at the experimental farm of the Agriculture Faculty, Rimbo Panjang, Kampar and carried out in Juni until September 2014. This research was carried out experimentally using randomized block design (RBD) non factorial consisted of 6 treatments with 4 repetitions which resulting 24 experimental plots. Each experimental unit consisted of 24 plants and 6 plants as samples. The treatments were: AN1: without rice husk ash with NPK 300 kg/ha (135 g/plot), AN2: rice husk ash 3 ton/ha (1350 g/plot) with NPK 300 kg/ha (135 g/plot), AN3: rice husk ash 6 ton/ha (2700 g/plot) with NPK 300 kg/ha (135 g/plot), AN4: without rice husk ash with NPK 600 kg/ha (270 g/plot), AN5: rice husk ash 3 ton/ha (1350 g/plot) with NPK 600 kg/ha (270 g/plot), AN6: rice husk ash 6 ton/ha (2700 g/plot) with NPK 600 kg/ha (270 g/plot). The results of experiment that was obtained using analysis of variance were tested further with DNMRT (Duncan\u27s New Multiple Range Test) at the level 5%. Based on the results of this research, the recommended doses are rice husk ash 3 ton/ha (1350 g/plot) and NPK 600 kg/ha (270 g/plot)

Campuran Kompos Tandan Kosong Kelapa Sawit Dengan Kompos Lcc Dan Pupuk Fosfor Terhadap Pertumbuhan Dan Hasil Sorgum (Sorghum Bicolor (L.))

This research is aimed to determine the effect of oil palm empty fruit bunches compost mixed with leguminosa cover crop compost and phosphorus fertilizers at some compositions and to get the best mixed toward growth and result of sorghum. This research was conducted at the experiment land of Agriculture Faculty of Riau University, Pekanbaru, from December 2013 to April 2014. This research used factorial completely randomized design (CRD) consisted of two factors and three replications. As for the treatment is: factor 1 is oil palm empty fruit bunches compost mixed with leguminosa cover crop compost (K) consist of four level, K1= 5 ton/ha oil palm empty fruit bunches compost, K2= 3,75 ton/ha oil palm empty fruit bunches compost + 1,25 ton/ha leguminosa cover crop compost, K3= 2,5 ton/ha oil palm empty fruit bunches compost + 2,5 ton/ha leguminosa cover crop compost, K4= 1,25 ton/ha oil palm empty fruit bunches compost + 3,75 ton/ha leguminosa cover crop compost. Factor 2 is phosphorus fertilizers (P) consist of three level, P0= without TSP, P1= 30 kg/ha TSP, P2= 60 kg/ha TSP. The results of this research showed that 1,25 ton/ha oil palm empty fruit bunches compost mixed with 3,75 ton/ha leguminosa cover crop compost and 60 kg/ha phosphorus fertilizers provide the best results for 245,20 g/m2(2,45 ton/ha) increased by 18,27% compared without P and is significant for the parameters of plant height, dry weight of plants, result per m2 and sorghum biomass

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
