Abstract

Pupuk kascing merupakan salah satu pupuk organik yang dapat memperbaiki sifat fisik, kimia dan biologi tanah, disamping itu penambahan pupuk NPK dapat membuat unsur hara lebih tersedia untuk pertumbuhan bibit kopi arabika (Coffea arabica L.). Tujuan penelitian ini untuk mengetahui pengaruh faktor tunggal pupuk kascing dan pupuk NPK, interaksi pupuk kascing dan pupuk NPK serta untuk mendapatkan dosis yang terbaik terhadap pertumbuhan bibit kopi arabika. Penelitian  dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Riau, Pekanbaru. Penelitian dilaksanakan dari bulan Desember 2017 sampai Maret 2018, Penelitian  menggunakan Rancangan Acak Lengkap (RAL) Faktorial terdiri 2 faktor, faktor pertama adalah  pemberian pupuk kascing yang terdiri dari empat taraf dosis yaitu : K0 (0 g per polybag), K1 (12,5 g per polybag), K2 (25 g per polybag), K3 (37,5 g per polybag). Faktor kedua adalah pemberian pupuk NPK dengan tiga taraf dosis yaitu : N1 (7,5 g per polybag), N2 (15 g per polybag), N3 (22,5 g per polybag). Dari kedua faktor diperoleh 12 kombinasi dengan 3 ulangan, terdapat 36 unit percobaan. Parameter yang diamati pertambahan tinggi tanaman, pertambahan jumlah daun tanaman, volume akar, rasio tajuk akar dan berat kering tanaman. Hasil penelitian menunjukkan interaksi pemberian pupuk kascing 25 g per polybag dan pupuk NPK 22,5 g per polybag memberikan hasil terbaik pada parameter pertambahan tinggi tanaman, pertambahan jumlah daun tanaman, volume akar, rasio tajuk akar dan berat kering tanaman. Kata Kunci : Kopi Arabika (Coffea arabica L.),  Pupuk Kascing, Pupuk NPK,           Pertumbuhan bibit.

Abstract

This study attempt to determine the impact of liquid foliar fertilizer (LFF) application to several soybean varieties on cropgrowth and yield components. This experiment was conducted in the Experimental Farm of the Agriculture Faculty, the University of Riau from March 2018 to May 2018 in a split-plot design with three replications. Three rates of foliar fertilizer; ie, without LFF, LFF with a concentration of 2 g.l-1of water, and LFF withconcentration of 4 g.l-1of waterwere  assigned as the main plot.  Five soybean varieties, namely Anjasmoro, Burangrang, Dena 1, Dega 1 and Detam 1 were used as subplot.Parameters observed were plant height, flowering date, harvesting date, dry seed weight after 15, 22  days after pollination,seed dry weight at harvest, seed growth accumulation rate, effective filling period, number of  filled pods per plant, number of seeds per plant, weight of 100 seeds, and seed weight per m2. Data were analyzed by the analysis of variance then followed by Duncan's multiple range test at a level of 5% probability. The results showed a variation of several soybean varieties. There is a tendency of an increase in some yield components due to application of LFF and between low to compare higher concentration of LFF.Application of LFF as supplementary fertilizer has significant effect on plant height, flowering date, and seed weight per m2 but has no effect on other parameters. Interaction between varieties with LFF affected significantly plant hight and flowering dates in which application of LFF tended to shortened time to flower and resulted taller plant height.This indicates the important use of foliar fertilizer to improve yield and yield components of soybean varieties. Keywords : folliar fertilizer, soybean varieties, crop growth, yield components

Abstract

This study aims to determine the effect of the interaction of soil treatment methods and tofu liquid waste fertilizer on the growth and yield of soybean plants and get the best combination of treatments. This research was carried out at the University of Riau's Faculty of Agriculture's Technical Implementation Unit (UPT) for 4 months from April to July 2018. The study was conducted experimentally in a 3 x 4 factorial form arranged according to a completely randomized design (RAL). The first factor is the method of tillage consisting of three levels: no tillage (TOT), minimum tillage and perfect tillage. The second factor is the dose of tofu liquid waste consists of four levels: 0 ml.2m-2, 250ml.2m-2, 500 ml.2m-2 and 750 ml.2m-2. The parameters observed were plant height, flowering age, harvest age, number of pods per plant, number of pithy pods per plant, weight of 100 seeds and dry seed production. Soil processing can accelerate flowering age and harvest age, increase the number of pithy pods per plant and dry seed production of soybean plants. Tofu wastewater fertilizer can increase plant height, accelerate flowering age and weight of 100 soybean seeds. Keywords: tillage, tofu liquid waste, soybeans

Abstract

The aim of the study was to obtain the better growth oil palm seedlings by providing trichocompos from basic ingredients and different doses. This study uses a cluster randomized design method (CRD) in 9 treatments and 3 replications.Observed including: seedling height, number of leaves, stem diameter, root canopy ratio, seedling dry weight and seedling quality index. The results showed that only the height of the oil palm seedlings was better given by the composision corn waste, market waste and cattle rumen trichocompos in 10-20 ton.ha-1 doses. Height of oil palm seedlings was increased by giving trichokompos based on corn waste or cattle rumen at doses of 15 and 20 ton.ha-1. Increased root canopy ratio increased by trichokompos based on corn waste and cattle rumen as much as 50 g.polybag-1.Keywords: Palm oil seedling, composision of basic materil and doses trichokompos

Abstract

The research aims to study the growth and yield of green beans from the provision of cow manure. The research was conducted at the Experimental Station of the Faculty of Agriculture, University of Riau, Pekanbaru from February to April 2018. Completely Randomized Design (CRD) was used in this experiment, with three replications. The cow manure treatment consists of five levels A = No Cow Manure, B = 5 tons. ha-1, C = 10 ton. ha-1, D = 15 tons. ha-1 and E = 20 ton. ha-1. The parameters observed were planted height, number of primary branches, age of flowering plants, harvest age, the number of plant pods, percentage of pithy pods, seed weight per m2 and weight of 1000 seeds. The results showed that green bean plants did not respond to the cow manure application and the nutrient requirements have been fulfilled from the application of Urea, TSPand KCl fertilizer. Keywords: cow manure, green bean,growth and yield.
