Abstract

The aim of this study was to determine the effect of palm oil fruit bunch ash, N fertilizer and interaction between palm oil fruit bunch ash and Nfertilizer on the growth and yield  of sweet corn. The research was carried out in the experiment station and the Plant Ecofisilogy Laboratory of the Faculty of Agriculture, University of Riau. This study used factorial randomized block design (RBD) consisting of two factors and 3 replications. The first factor was palm oil fruit bunch ash which consists of four levels: K0: 0 t.ha-1, K1: 1.5 t.ha-1 (0.9 kg. 6m-2), K2: 2 t.ha-1 (1.2 kg. 6m-2), K3: 2.5 t.ha-1 (1.5 kg. 6m-2). The second factor was N fertilizer which consists of two levels, namely: P1: N 115 kg.ha-1 (69 g. 6m-2) P2: Urea 138 kg. Ha-1 (82.8 g. 6m-2). The results showed that the increase in palm oil fruit bunch ash increased the plant height, number of leaves, and number of cobs harvested. Increasing the N dose only increases plant height. The interaction of palm oil bins and N fertilizers only increases plant height.Keywords: Sweet corn, palm oil bare ash, N fertilizer

Abstract

Cocoa (Theobroma cacao L.) is one of the large plantations after oil palm. The increase in cocoa nursery can be accompanied by the utilization of waste derived from palm oil, namely oil palm empty fruit bunches (OPEFB). OPEFB can be useful as organic fertilizer because it can improve soil physical, chemical and biological properties. The use of OPEFB as organic fertilizer will also reduce excessive use of NPK. Utilization of OPEFB into organic fertilizer can be in the form of compost or raw OPEFB organic matter plus cellulolytic and lignolytic microbes. This study aims to determine the effect of NPK fertilizer and OPEFB compost on the growth of cocoa seedlings. This research was conducted experimentally using a completely randomized design (CRD) consisting of 9 treatments and 3 replications. Parameters of observation were plant height, stem diameter, number of leaves, root canopy ratio, dry weight of seedlings and age of planting. The results showed that the provision of 100 g/polybag OPEFB compost plus 50% NPK fertilizer (2 g / polybag) could provide good growth in cocoa seeds (Theobroma cacao L.).Keyword : Cocoa, compost, cellulolytic bacteria, lignolytic bacteria, OPEFB

Abstract

This research aims to determine the effect and get the best combination of organic mulch congongrass and chicken manure on the growth and production of onion (Allium ascalonicum L.) The research was conducted in experimental garden of the Faculty of Agriculture, University of Riau on Campus Bina widya Km 12.5 Kelurahan Simpang Baru Kecamatan Tampan Pekanbaru from April to June 2017. The research was conducted in a randomized complete design (RAL). The treatment was done by doing a combination between organic mulch with chicken manure. The parameters in this observation were plant height, number of leaves, number of tubers, percentage of tubers, tuber weight and tuber weight of storage. The results obtained were analyzed statistically using variance analysis and continued with a 5% DNMRT advanced test. The results showed that combination treatment without organic mulch congongrass and chicken manure 13,890 kg/ha can increase plant height, leaf number, tuber weight, fresh weight of tuber and tuber weight is saving but no effect on the number of onion crop tubers. Combination treatment without the application of organic mulch congongrass and chicken manure 13,890 kg/ha can increase fresh weight of onion plant as much as 112,74% and save weight of onion plant as much as 250% compared with mulching and without chicken manure. Keyword: Combination, organic mulch congongrass, chicken manure

Abstract

The low productivity of paddy in Langsat Permai Village, Bunga Raya District, Siak Regency, one of them is causes the unavailability of sufficient water for crop cultivation, so it is necessary to do water management by making canal blocking to be used on rice plants in the area. This is done to meet the water needs of rice plants during the dry season. Therefore, assistance is provided through water management in Langsat Permai Village, Bunga Raya District, Siak Regency. Mentoring strategies are carried out by discussing directly with farmer groups about the impact of making canal blocking. Through this activity, the availability of water for rice plants during the dry season is fulfilled. Production of 1 Ha of rice before the blocking canal produced 4-5 tons/harvest to 6-7.8 tons/harvest after the canal blocking.

Abstract

This study aims to determine the interaction of rice straw compost and P fertilizer on the growth and yield of soybean plants (Glycine max (L.) Merril). This research was conducted in the experimental station of the Faculty of Agriculture, Riau University, starting from June to October 2017. This study used a Randomized Block Design (RBD) consisting of 2 factors and 3 replications. The first factor was the dose of rice straw compost (K) consisting of K0: without the provision of rice straw compost, K1: Compost rice straw with a dose of 5 tons. Ha-1, K2: Compost rice straw with a dose of 10 tons. Ha-1, K3 : Compost Rice straw with a dose of 15 tons. Ha-1. The second factor is the dose of TSP fertilizer (P) which consists of P1: TSP 300 kg. Ha-1, P2: TSP 326 kg. Ha-1. The results of this study indicate that rice straw compost increases the growth and yield of soybean plants. Compost of rice straw can increase plant height, number of rice pods, total number of pods, yield per plot and weight of 100 seeds. Application of P fertilizer does not increase the growth and yield of soybean plants. The interaction of rice straw compost and P fertilizer did not increase the growth and yield of soybean plants. Keywords: Soybeans, rice straw compost, TSP fertilizer

Abstract

This study aims to determine the effect of concentration and fermentation durationand the best concentration at each fermentation time of fruit and vegetable waste to rose varieties baby rose, conducted inthe Facultyof Agricultur, Riau University from April to July 2017. This research using a randomized block design (RAK) consisting of two factors and three replications. The first factor was the concentration of fermented fruit and vegetable waste with five levels, i.e. 0 ml.l-1 water,  5 ml.l-1 water, 10 ml.l-1 water, 15 ml. l-1 water and 20 ml. l-1 water. The second factor was the duration of fermentation fruit and vegetable waste with of three levels, namely 10 days of fermentation, 20 days fermentation and 30 days of fermentation. Parameters measured were the number of crop shoots, shoot length, when the first flowers appear, flower stem length, petal number and the number of florets crop planting. The results showed that the concentration wastes fermented fruits and vegetables can increase the number of shoots per plant, shoot length, when the first flowers appear, flower stem length, diameter flowers bloom, petal number per florets and the number of buds per plant. Treatment concentrations of 5-20 ml.l-1 water better than the treatment 0 ml.l-1 water. Treatment of 5ml.l-1water is the best treatment to increase the number of florets per plant, while the fermentation treatment does not give effect to all parameters. Treatment concentrations of 5 ml.l-1 water on a long fermentation 10, 20 and 30 days is the best treatment to increase the number of florets per plant. Keywords: roses, concentration, fermentation
