Abstract

The purpose of this research is to determine interaction between composition of growing medium, PGR concentration to growth, influence of composition of growing medium toward growth and harvest of pakchoy. The present study uses factorial randomized group design consisting of two factors with three replicates and 2 sample plants. Factor I is growing medium composition of 3 levels while factor II is a level 3 PGR concentration. The composition of these factors is factor I: M 3 garden soil: 1 manure, M 2 = 2 garden soil: 2 Manure, M 3 = 1 = 1 garden soil: 3 manure. Factor II consists of: K = 2 ml/liter of water, K 2 = 4 ml/liter of water, K = 6 ml / liter of water. Results from this study indicate that the combined treatment of manure and PGR concentration has significant effect on observation of plant length at 28 days of age. However, it does not give real interaction to variables of number of leaves, plant length, and gross at all ages of observation. The use of manure has significant effect on all observation variables. The highest average plant length, leaf number, and highest gross were obtained at the treatment of M 2 3 (2 garden soil: 2 manure). Treatment of PGR concentration had significant effect on all observation variables. Average length of plants, number of leaves, and highest gross were obtained at treatment of K 2 ml / ltr water.

Abstract

The average production of sugar is 2.26 million tons per year, while consumption is about 5.10 million tons per year. This is what causes the number of production and consumption of sugar shows a fairly high gap. Extensification approach in increasing sugar cane production to achieve sugar self sufficiency target is quite difficult to achieve, so intensification program is one of the efforts that can be done through evaluation and optimization phase of germination and plant growth with application of growth regulator (Fitohormon). If this is done then to obtain a sugar cane plant that has the productivity and optimal yield is likely to be achieved (Ahmad Khuluq and Ruly Hamida, 2014). The experiment was conducted at Experimental Garden of Agriculture Faculty, Merdeka University, April-June 2017. Using Randomized Block Design with 3 replications. and 8 doses of Hormax growing growth regulator, among others: 0 ml/l water (Control); 1 ml/l water; 2 ml/l water; 3 ml/l water; 4 ml/l water; 5 ml/l water; 6 ml/l water; 7 ml/l water. In conclusion, the use of Hormax significantly affected the germination rate, the number of leaves, the number of roots, the wet weight and the dry weight per cane plant. Increased dose of Hormax followed by an increase in all variables of sugar cane observation. The highest results were shown dose of Hormax 7 ml/l water), but statistically not significantly different from the treatment dose of Hormax 6 ml/l water) and dose of Hormax 5 ml/l water. It is recommended that to assist the germination and early growth of sugar cane using a dose of Hormax 5 ml/l water.

Abstract

One important factor in cultivation that supports the success of plant life is the problem of fertilization. A common problem that occurs in fertilization is the low efficiency of nutrient uptake by plants. The efficiency of fertilizing nitrogen (N) and potassium (K) is relatively low, ranging from 30-40%. The efficiency of phosphorus (P) fertilization by plants is also low, around 15-20% (Rukmana, 2002). Efforts to improve the efficiency of fertilizer use can be pursued through the principle of the right type, the right dose, the right way, the right time of application and balanced according to the needs of plants (Syafruddin et al, 2009). The purpose of this study was to determine the extent to which the effectiveness (appropriate) use of urea fertilizer (nitrogen sources) on plant growth and yield Baby Kailan (Brassica alboglabra L.). The study was conducted in the Experimental Garden of the Faculty of Agriculture, Merdeka University Surabaya, on Jalan Ketintang Madya VII-2 Surabaya, East Java with a height of ± 5 m above sea level, carried out from March to April 2019. This study used a Randomized Group Design (RBD) consisting six (6) treatments with three (3) replications and two (2) sample plants. As for the treatment given, namely the dose of urea fertilizer consisting of six (6) doses, namely: A = No Urea Fertilizer (Control); B = 75 kg / ha Urea Fertilizer (0.15 gram per plant); C = Urea fertilizer 150 kg / ha (0.30 gram per plant); D = Urea Fertilizer 225 kg / Ha (0.45 gram per plant); E = Urea fertilizer 300 kg / ha (0.60 gram per plant); F = Urea Fertilizer 375 kg / Ha (0.75 gram per plant) The results of the study show that the use of urea fertilizer has a very significant effect on the variable plant length, number of leaves and the wet weight of baby kailan plants. Effective (appropriate) dosage in the use of urea fertilizer during growth and yield of baby kailan plants tends to be achieved with urea fertilizer dosages of 300 kg per hectare (0.60 gram per plant), although the highest growth and yield tends to be indicated by urea fertilizer dosages 375 kg per hectares (0.75 grams per plant), because statistically (LSD 5%) between the two treatments the dose of urea fertilizer was not significantly different.

Abstract

This study aims to determine the effect of combined treatment plant extracts bintaro and giving the extract concentration on the mortality of armyworm pests. While the research method used factorial experiments conducted with a completely randomized design (CRD). Treatment Factor I was the Bintaro plant organs extracted consisting of 4 levels consisting of 4 combinations of Bintaro organs and 5 combinations of extract concentrations so that there were 20 combinations and 1 control (without giving the extract) so that a total of 21 treatments were repeated 3 times, a total of 63 units. trial. The experimental unit was using a jar with a height of 6 cm, a diameter of 12.5 cm with 8 instar 1 tails, so it needed 504 instar 1 caterpillars. Caterpillar feed is sunflower leaves that are added / replaced every day. The results showed that there was an insignificant effect of the combination of the treatment of Bintaro plant organ extracts and the concentration of Bintaro plant organ extracts with the mortality rate (%) of armyworms, where observations on days 4, 8, 12 and 16 showed a significant value> 0, 05 with the highest R Square achievement on the 16th day of observation of 0.0675 (6.75%), meaning that only a 6.75% mortality rate (%) of armyworms was affected by the combination of the above treatments. The insignificant effect at all levels of treatment factors was the concentration of Bintaro plant's organ extract (K), but the K5 treatment (12.5% extract concentration) showed a tendency to be better than the K1, K2, K3, and K4 treatments with an R Square value of 0, 418370978 (41.84%) means a number of 41.85% mortality (%) armyworms due to K5 treatment (12.5% extract concentration), the remaining 58.15% due to external factors and insignificant influence at all factor levels treatment of Bintaro plant organ extract (B), but treatment B1 (leaf organ extract) showed a better tendency than treatment B2, B3, and B4 with a significant value of F (0.264002509> 0.05) and R Square of 0.296443348 ( 29.64%).
