Abstract

The purpose of this research is to determine the influence of interaction between organic growth regulator concentration and immersion duration time, as well as the influence of each of these factors on germination sugarcane (Saccharum officinarum L)cuttings. This study uses a randomized group design (RAK) with two factors, immersion duration (P)in 4 levels of P1 (1 minute), P2 (2 min), P 3 (3minutes), and P4 (4 minutes) and two levels of organic plant growth regulator (K), 4 cc/ liter, and 5 cc per liter of water, each treatment is repeated 3 times to obtain 24 treatments. The results reveals that a)There is a significant interaction effect due to immersion duration and concentrations of organic growth regulator to the observed variables: number of roots per plant, root length per plant, gross weight per plant and net weight per plant at the end of the observation b). Each factor of both immersion and concentration of organic plant growth provide significant influence on all the variables studied. 0). The highest value on all the variables observed is achieved by K2P4 treatment with concentration of 5 cc/liter and 4 minutes immersion; yet statistically, the optimum value is achieved by treatment K2P3 or influence of K2 and P3treatment.

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).

Abstract

The number of clumps per hectare is influenced by the percentage of germination of kinds of seeds used (Tamelsilva, 2006). Increasing the production of sugar cane as a raw material for sugar is absolutely necessary. One of the causes of the decline in sugarcane productivity is the problem in the use of seeds, such as sugarcane seeds used by farmers who are less qualified (Iskandar, 2005). The study was conducted at the Experimental Garden of the Faculty of Agriculture, Merdeka University, Surabaya, in March-April 2017. Using a Randomized Block Design (RBD) consisting of six treatment combinations with three replications and two sample plants. As for the combination treatment, as follows: A (Variety LPS-864 and Buds Buds section 20); B (Variant LPS-864 and Mata Tunas Middle-segment-14); C (Variety of LPS-864 and Mata Tunas at the base of Section-08); D (Variety of LPS-891 and Buds section of Section-20); E (Variant LPS-891 and Mata Tunas Middle-segment-14); F (Variety of LPS-891 and Mata Tunas at the base of segment-08). The results showed that the treatment of the combination of the location of the buds and varieties significantly affected the observation of the number of leaves, but the effect was very significant on the variable of germination speed and length of the plant and the wet weight of the plant. Combination treatment of bud location on segment-20 (shoots) on the sugar cane varieties LPS-891 and cane varieties LPS-864 showed the best results on all observational variables, although the highest results always indicated the location of bud-section 20 buds (shoots) on sugarcane varieties LPS-891, but statistically not significantly different.

Abstract

The research objective was to determine the effect of NPK compound fertilizer dosage on the growth and yield of purple eggplant (Solanum melongena L). The research was carried out at the Nursery, Agribusiness Sub-Terminal, Food Security and Agriculture Service of Surabaya City, on Jl. Ketintang Madya VII Surabaya, East Java with an altitude of ± 5 m above sea level. Conducted from April to June 2018. his study used a randomized block design (RBD) consisting of six dose treatments with three replications and two sample plants. The NPK compound fertilizer dosage treatment included: D0 = without NPK (Control); D1 = NPK 100 kg / Ha; D2 = NPK dose of 200 kg / ha; D3 = NPK dose of 300 kg / ha; D4 = NPK dosage 400 kg / ha; D5 = NPK dose of 500 kg / ha.The conclusion of the study, namely the NPK dose treatment had a very significant effect on plant height, number of leaves, number of fruits and wet weight per plant of purple eggplant (Solanum melongena L). Treatment with NPK dose of 500 kg / Ha showed the highest growth and yield, although statistically it was not significantly different from the NPK treatment dose of 400 kg / Ha and the NPK treatment dose of 300 kg / Ha (optimum dose).

Abstract

Tobacco as one of the plantation crop commodities can contribute to state income, but on the other hand there are many things that become obstacles for farmers in increasing production and business income, there is no government support in controlling tobacco marketing patterns, there is no cooperative relationship between farmers and tobacco companies that mutual benefits, as well as some problems in tobacco farmer institutions. Research purposes To find out the current condition of East Java tobacco farmers, model for the tobacco area based on farmers' corporations in East Java and program in realizing a model for developing tobacco plantation areas based on smallholder corporations in East Java. The research objectives are: (1) to determine the current condition of tobacco farmers in East Java, (2) to develop an institutional model for tobacco plantations based on farmers' corporations, and (3) to develop programs to realize a model for developing tobacco plantation areas based on farmers' corporations. The data analysis method used in this study is trend analysis, description analysis. Research Results: Program implementation requires coordination and cooperation of various parties related to tobacco. Furthermore, at each stage of implementation, it is necessary to carry out periodic evaluations to find out the shortcomings so that adjustments and improvements can be made at the next stage and it is necessary to follow the rules that have been agreed upon in the memorandum of agreement.
