Abstract

Watermelon cultivation has problems of seed germination. Seeds of watermelon that immediately sowing will slow in germinating, not even germinate at all. This is caused by the dormancy period of seeds, which is wrapped in seed institutions by the skin layer. Currently there has been considerable effort to improve seed viability, one using scarification techniques and soaking treatment of growth regulators. Based on the description above, the research is conducted to find out the influence of seed cutting and the effect of the old Atonic immersion on seed viability and growth of watermelon seed (Citrullus vulgaris, Schard). The method used in this research is Randomized Block Design (RAK). The first factor was no breaking (P1) and with the breaking of the seed shell (P2), the second factor was 4 long Atonic immersion (J1 = 0 min, J2 = 45 min, J3 = 90 min, and J4 = 135 min) with 3 repetitions. The Atonic concentration used is 1 ml / l of water. So there are 8 treatment combinations and 24 experimental units. Based on the results of the research, the following conclusions can be obtained: 1) there is the best combination between watermelon seedlings and duration of immersion of Auksin on viability and growth of non-seedled watermelon plants (Citrullus vulgaris), 2) Scarification combination and immersion time Auksin 45 minutes (P2J2) watermelon non seeds showed a very significant effect on seed viability and other observation variables up to 35 hst. 3) combination of scarification and duration of immersion of 45 to 90 minutes with 1 ml of perliter concentration potentially increase the viability and growth of seed seedling watermelon.

Abstract

The flower cabbage (Brassica oleraceea L.) is a type of vegetable plant belonging to the family of cabbage plants (Cruciferae). Flower cabbage often called "cauliflower" has many benefits to consume, because it contains calories, protein, carbohydrates, calcium, and vitamins A, B1 and C. Farming is very much affected by the state of agricultural land, a problem that often occurs due to lack of elemental content nutrients in the soil that affect the inflorescence and flower cabbage growth. Therefore, to increase the yield of cabbage flowers offered the method of land optimization with the addition of nutrients in the form of phosphorous soil and also the addition of gibberellin hormone that has a role to flowering cabbage plants. The research was conducted by using Randomized Block Design (RBD) in divided plots with 2 treatments, Phosphorus (P) as the main plot with 3 treatment levels P1 (100 kg / ha), P2 (125 kg / ha) and P3 150 kg/ha then the concentration of Giberelin (K) as a subplot with 3 levels of treatment K1 (75 mg / L), K2 (100 mg / L) and K3 (125 mg / L)). From the result of the combination of the two treatments were 9 treatment combinations, repeated 3 times to obtain 27 units combination of treatments, each experimental plot consisted of 15 plants. Parameters observed include plant height, number of leaves, number of flowering plants, flower diameter and flower weight. The result of the research showed no significant interaction in all plant variables but the dosage of phosphorus fertilizer gave significant effect on the height variable of the 10 hst plant on the P1 (100 kg/ha) treatment, the leaf number variant showed significant effect at age 40 hst on P3 treatment (150 kg / ha), the number of flowering plant variables showed significant effect of 60 hst on P3 treatment (150 kg / ha), flower diameter variables showed significant differences in P3 treatment (150 kg / ha). The best treatment is P3 treatment (150 kg / ha). Gibberellin concentrations did not have a real effect on all plant variants.

Abstract

Objective of the study was to know the effect of application of phosphate fertilizer and cow manure on the growth and yield of sesame. The experiment was conducted from February to May 2017 at field Rembang Village, Kesamben district, Blitar Regency. This research is factorial randomized block design consisting two factor with three replication following the treatments of phosphate fertilizer P1= 100 kg ha-1, P2= 150 kg ha-1, P3= 200 kg ha-1 and cow manure dose O1 = 5 ton ha-1, O2= 7,5 ton ha, S3= 10 ton ha-1 were test. The results showed that there ’s no interaction between dose of phosphate fertilizer treatments and dose of cow manure treatments. The dose 100 kg ha-1 of phosphate fertilizer is the best treatment on growth and yield of sesame. The dose 10 ton ha of cow manure is best treatment on growth and yield of sesame.

Abstract

The purpose of this research is to understanding the effect of organic matter on BPS activity in reducing sulfate. Research carried out in batch culture using erlenmeyer, and using a completely randomized design (CRD). The treatment given is organic matter amounted to 308 mg / L, 617 mg / L and 1.234 mg / L and control. Each treatment was repeated 3 times. The parameters observed in this study is SO4- concentration. Using Duncan New Multiple Range Test (DNMRT) at 5% level for data analysis. The results showed that the molecular concentration of 617 mg / L was able to decrease the sulfate concentration at the fastest, then consecutively the concentration of molasses 1.234 mg / L, and control. Based on the Anova test the significant value is less than 0.05. Thus it can be stated that there is an effect of addition molasses to decrease sulfate concentration by sulfate reducing bacteria consortium.

Abstract

Lettuce vegetables (Lactuca sativa L.) much needed by the community to meet the nutritional needs, but lettuce production is still low because of low productivity. Increasing the quality and quantity of vegetables grown on polybags is by fertilizing and arranging the composition of the planting medium. Provision of fertilizer aims to increase the supply of nutrients needed plants to boost the production and quality of crops. Fertilizer is to provide or add nutrients that plants need. However, fertilizer will tend to cause high production value and less appropriate with vegetable planting at home, therefore more optimized setting the composition of planting media. Planting media should be able to provide nutrients needed by plants. Farmers use plant residual organic materials such as rice husk as and cockpit for vegetable cultivation. The rice husk is the outermost part of the grain. The rice husk ash usually contains N 0.32%, P 0.15%, K 0.31%, Ca 0.96%, Fe 180 ppm, Mn 80.4 ppm Zn 14.10 ppm and pH 6, 8 which is expected to meet the needs of plant nutrients. The study was prepared using a complete randomized design with one factor that is the addition of planting media in the form of rice husk ash with the proportion of top soil and rice husk ash as follows: M1 (3: 1), M2 (2: 2), and M3 (1: 3). The observed variables were stem height, crown dry weight, and root dry weight. Data analysis used F Test 5% and continued with Duncan Multiple Range Test (DMRT) 5%. The results obtained at plant height of M3 (1: 3) gave the best result where there was a plant height increase of 40 cm from the first day of planting until the third day, the addition of rice husk ash did not affect the addition of root dry weight and dry weight of crown.
