Abstract

This study aims to determine how far a combination of manure and urea fertilizer influence on the growth and yield of kale land. Percobahan do in the garden percobahan Merdeka University Faculty of Agriculture, Surabaya, in the village of the District Karah Jambangan Surabaya. This research method using Randomized Trial group (RAK) factorial arranged, composed of two factors, namely: manure with 3 levels of treatment and the provision of nitrogen fertilizer (urea) with three levels of treatment. Maing each treatment was repeated 3 times and each combination treatment consisting of two plants. The results show there is no interaction on manure and nitrogen fertilizer dosage in all parameters of both observation plant leaf number, plant height and fresh weight pertanaman.begitu also manure does not provide real pengarruh against all plant nitrogen fertilizer dosing significant effect on parameter above the number of leaves, plant height, fresh weight per plant.

Abstract

Indonesia is one of the countries with the largest number of smokers in the world after China, the United States and Russia.

Abstract

The lettuce is a leafy vegetable that comes from the (state) temperate. Historically, this plant has been cultivated since 2500 years ago. Lettuce plants came from the Americas. This is evidenced by Christopher Columbus in 1493 that found the plant lettuce in the western Hemisphere and the Bahamas (Rukmana, 1994). This study aims to determine the effect of growing media on growth factors, the influence of the concentration of liquid organic fertilizer (POC), the interaction effect of these two factors and yield of lettuce. The results showed There is a very real effect of growing media composition in all parameters studied were long observation of plants, number of leaves and fresh weight per plant. The best results were achieved by treatment K2 is 2 kg of manure per plant. There is a very real effect of concentrated liquid fertilizer (POC) "Supermer" on all parameters studied were long observation of plants, number of leaves and fresh weight per plant. The best results are achieved by P4 treatment The concentration POC 2 ml / liter of water. There is no real interaction due to a combination treatment of the media composition and concentration of liquid organic fertilizer (POC) "Supermes".

Abstract

Crab (crab) is one of the fishery products that is generally perishable. This is likely due to poor handling that decreases the quality. This research aims to determine factors that can affect the quality of crab and recommend a priority strategy most appropriate to apply quality control on crab handling at PT Tonga Tiur Putra in expanding its business. The present research uses AHP (Analytical Hierarchy Process) method. Three decision-makers in PT. Tonga Tiur Putra were taken as respondents. Analysis factor reveals that factor affecting the quality of crab meat is transportation. The proper alternative to control the quality of crab is human resource training.

Abstract

The aim of this research was to identify the influence of giberellin hormone concentration and its application frequency on the growth and the yield of tomato fruit. This research had been undertaken at Agrotechnopark, the University of Jember 6 November 2017 - 10 February 2018. The experiment using randomized complete block design (RCBD) with two factors namely the concentration of giberellin hormone consisted of 4 levels (0 ppm, 50 ppm, 75 ppm, 100 ppm) and the second was its frequency application consisted of three levels (spraying once every 7 days, 14 days, and 21 days). Reviews These were arranged in a factorial design and each combination was repeated by three times. The results Showed that (1) siqnificantly influenced concentrations of hormone on the growth and the yield of tomatoes. (2) the frequency of its application on the number affected siqnificantly productive branches, the number and weight of fruit, the weight of the tomato fruit. (3) there was no interaction of giberellin and its aplication on all paramters. (4) the best treatment is G3F3, the gibereellin concentration of 100 ppm and the frequency of 21 days once.

Abstract

Liquid organic fertilizer Tambsil is a complete liquid organic fertilizer, which is formulated to meet the needs and challenges of the farmers or entrepreneurs in agriculture and plantations in order to get results or harvest prime. Where the liquid organic fertilizer contains a complete nutrient, both elements of macro and micro elements essential for soil fertility and plant growth. A liquid that can be absorbed by plants through leaf stomata or mouth. Functioning as a stimulator and is very safe for human and animal health as well as a very friendly environment (Anonymous, 2017). The purpose of this study to determine the extent of the effect of the use of urea fertilizer on the growth and yield of Green Spinach (Amaranthus tricolorL.).Research conducted at the Faculty of Agriculture Experimental Station Freedom Surabaya, on the road Ketintang Madya VII-2 Surabaya. This study uses a randomized block design (RAK) consists of six (6) treatment without liquid organic fertilizer (control) and liquid organic fertilizer dose 2,5cc; 5,0cc; 7,5cc; 10,0cc; 12,5cc per liter of water with three (3) replicates and two (2) samples of plants. The results of the study are as follows: a. There is a very real effect on the observation variables plant height, leaf number and fresh weight per plant and plant fresh weight per polybag. b. The treatment dosing liquid organic fertilizer Tambsil 12.5 cc per liter of water to produce growth and yields the highest (maximum dose) kale crop land, although it was not statistically significantly different from the dosage of liquid organic fertilizer Tambsil 10.0 cc per liter of water (Dose The optimum or effective dose).
