Abstract

use of vine stem cuttings seeds has the advantage of providing more number of seeds and later new plants which will have properties such as the parent, grapes are already known as one of the classy fruits in the world, both fresh consumed and processed products, processed grape products which is known as wine is able to penetrate the price of Rp5.7 billion per bottle is famously expensive in subtropical countries. This study aims to determine the duration of soaking and concentration of liquid organic fertilizer (POC) of cow urine on the initial growth of grape cuttings. The study was conducted in the Experimental Garden Faculty of Agriculture, Merdeka University, Surabaya Jl. Ketintang Madya VII / 2 Surabaya, with a height of ± 5 meters above sea level. This study uses a randomized block design (RBD) arranged according to factorial patterns with two (2) factors, namely factor I = duration of immersion consisting of 4 levels, including: L0 = 0 minutes (control), L1 = cuttings of grapes soaked for 15 minute, L2 = cuttings of grapes soaked for 30 minutes, L3 = cuttings of grapes soaked for 45 minutes, while factor II = concentration of organic ZPT consists of 3 levels, including P0: 0 ml / liter (water), P1: 10 ml cow urine per liter of water, P2: 20 ml cow urine per liter of water, P3: 30 ml cow urine per liter of water, P4: 40 ml cow urine per liter of water, based on the results of the study, conclusions can be drawn. There was a significant interaction at the F5% test level on the variables studied, namely the length of the vine cuttings at 42 days after planting and was best achieved by a combination of P3L2 treatment compared to other treatments, although it was not significantly different from the combination of P2L3 and P4L2 treatments. significant from both the POC concentration factor and the immersion length factor under study, mainly in the shoot length variable at 42 days after planting. Statistically, a better value for all of these variables is achieved by the P3 treatment that is 30% ml / liter of water and the L2 treatment that is 30 minutes.

Abstract

The area of rainfed lowland rice in Indonesia was 3,292,578 ha or 24% of the total area of rice, but the used is still very small, so that opportunities are still open for the development of rice plants. The main constraints on rainfed lowland are drought stress and inefficient use of nitrogen (N) and phosphorus (P) nutrients. The purpose of this study was to determine the effect of mycorrhizal fungi on the efficient use of nitrogen and phosphorus in rice planted in rainfed lowland. This research was conducted in rainfed lowland in April to July 2019 in the village of Demangan, Sambi, Boyolali, Central Java. The research method was a randomized completely block design. Factor 1: Doses of nitrogen fertilizer (N) 0; 45; 90; 135 kg/ha. Factor 2: phosphorus dose (P) 0; 25; 50; 75 kg/ha. Observations included the number of total tillers, number of productive tillers, panicle number, panicle length, 1000 grain weight, and grain weight per plot. Data Analysis was analysis of variance. If there was a difference between treatments then it was tested further by using Duncan's New Multiple Range Test at 5% level. To know the relationship of direct and indirect influence, regression and correlation analysis were done. Data were analyzed by computer using SAS for window 9.0 programs. The results showed that the application of VAM could save the use of nitrogen fertilizer and eliminate the use of phosphorus fertilizer.

Abstract

One of the environmentally friendly ways to increase soybean production was to use organic fertilizers and mycorrhiza. This study aimed to determine the effect of cow manure dose and a dose of mycorrhiza on the growth and yield of soybean varieties Devon I. The study was conducted in April to September 2019 in Teguhan village, Sragen Regency, altitude 86 masl, with the grumosol soil type. This study used a randomized block design Complete by a factor of two treatments, the first factor dose of cow manure consists of four levels ie K0 = 0 tonnes / ha, K1 = 5 tonnes / ha, K2 = 10 tonnes / ha, K3 = 15 ton / ha and a dose of mycorrhiza consists of three levels ie M0 = 0 g, M1 = 3 g, M2 = 6 g per plant. The use of fertilizer was reduced by half a dose recommendation. The results showed that the dose of cow manure significantly affected the growth and yield of soybean, the mycorrhiza dose had no significant effect on the growth and yield of soybean. The lowest productivity in this study in the treatment without cow manure (1.158 tonnes/ha) and the highest productivity in the treatment of cow manure is 15 tonnes/ha (1, 46 tonnes/ha).

Abstract

This study aimed abundance for brown plant hopper (bph) in rice plants against the presence in natural enemies to maintain productivity in rice plants. The study was conducted in the villages in Gempolsari, Penatar sewu and Sentul, Tanggulangin district, Sidoarjo, East Java in May 2019 to October 2019. The research was conducted using survey methods. The research location was selected using by purposive sampling method, which is the area with the highest percentage of attacks, has been attacked at least 3 times the growing season, Ciherang rice varieties, and was reported as brown plant hopper endemic area in 3 villages of Tanggulangin District, Sidoarjo. The results showed population abundance, percentage of attack rates, lowest intensity of brown plant hopper attacks occurred in Gempolsari village and the highest in Sentul village while the composition and abundance of natural enemies of brown plant hopper were dominated by odonata family then followed by families Salticidae, Tetragnathidae and Coccinellidae (Coccinela repanda).

Abstract

Urban vegetable cultivation using the aquaponic system can be considered as a future agricultural consideration because fish manure and fish food residues can become nutrients for plants after being decomposed by micro-organisms in pond water. The study aims to determine the availability of nutrients and dissolved salts in catfish ponds for 5 weeks before harvest and the growth of water spinach plants (Ipomoea aquatica) in aquaponic cultivation systems. The study was conducted at the Greenhouse UPN Veteran in East Java using 4 catfish ponds as a test given EM4 probiotic solution. Probiotics EM4 given as much as 20 ml per pool as a decomposer. Control is done by planting water spinach on soil media. Observations are carried out every week. The results showed 1). Water spinach plants planted with aquaponic systems have poor growth compared to those planted using soil media. 2). Nutrient concentration and salt content in pool water always increase during the study.

Abstract

purpose of this study was to determine the extent of the effect of the provision of GH growth regulators on growth and yield in onion plants. This research was conducted in the Research Field of the Faculty of Agriculture, Merdeka University, Surabaya from April to June 2019. This study used a Randomized Block Design (RBD) consisting of six treatments of GHOS, with three replications and using two sample plants. Use of ZPT Ghost fertilizer at doses Z = without fertilizer / control, Z1 = 1 ml / l / plant, Z2 = 2 ml / l / plant, Z30 = 3 ml / l / plant, Z = 4 ml / l / plant, and Z = 5 ml / l / plant. Observations made consisted of plant length, number of leaves, plant wet weight, plant tuber weight, and number of plant tuber. The results showed that the treatment of GHOS ZPT dose significantly affected all observed variables, namely plant length, number of leaves, number of tubers, plant wet weight and tuber weight of onion (Allium ascalonicum L.). The treatment of GHOS dose of 5ml per liter of water showed the highest growth and yield with a plant length of 30.16 cm, number of leaves 46.00, plant wet weight 68.33 grams, plant tuber weight 49.00 grams, and number of plant tubers 10 , 00 although statistically not significantly different from the ZPT GHOS fertilizer treatment using a dose of 1ml per liter of water with a plant length of 29.00 cm, number of leaves 34.83, plant wet weight 58.16 grams, plant tuber weight 38.56 grams and number of plant tubers 8,16.
