Abstract

The purpose of this study is to determine the effect of IBA plant growth regulators (Indole Butyric Acid)on germination of sugarcane cuttings (Saccharwn o_mcinarum L). The experimental materials include PSJT 941 variety of sugarcane cuttings, soil and manure as medium with 2: 1 ratio. IBA and 50% alcohol is used as treatment. Pest and disease controls used Basudin 60 EC and Dithane M-45. This study uses Randomized Block Design (RAK) with three replicates and each replicate consisted of 2 sample plants. The treatment is as follows: Ko: without treatment, K1: 500 ppm, K2: 1000 ppm, K3: 1500 ppm, K4: 2000 ppm. The study reveals that treatment of K4 IBA solution (2000 ppm)has very significant effect on variables of germination speed, shoot length, number of leaves and number of roots, and significantly different at root length. Administration of IBA solution at concentration of 1500 ppm accelerated germination time of sugar cane cuttings, occurred on the fourth day (fourth). Administration of IBA solution at 2000 ppm gave the highest result which was not different with 1500 ppm concentration on shoot length, leaf number, root length and root number. The higher the concentration of IBA, the higher the shoot length, the number of leaves, the length of the roots and the number of roots of sugar cane produced.

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

The purpose of this study is to examine the effect of the dose and time of NPK fertilizer application on the growth and yield of tomato plants (Lycopersicum esculentum Mill). The study was conducted from April to July 2018 at the Experimental Garden of the Faculty of Agriculture, Merdeka University Surabaya, on Ketintang Madya VII-2 Street Surabaya, East Java with altitude of ± 5 m above sea level. The study used Factorial Randomized Block Design (RBD) consisting of two factors with three replications and two sample plants. The first factor was NPK fertilizer doses (N1 = NPK 2 gr / plant; N2 = NPK 4 gr / plant; N3 = NPK 6 gr / plant) and the second factor was the time of NPK application (W1 = day 0; W2 = day 0-14; W3 = day 0-14-28). The results shows that the combination treatment of dose and application time of NPK has a very significant effect on plant height, number of leaves, total fruit number and total fruit weight of tomato plants. The combination treatment of N3W3 (NPK 6 gr / plant and day 0-14-28) appears to produce the highest growth and yield of tomato plants though, statistically (BNT 5%), this was not significantly different from the combination treatment of N2W3 (NPK 4 gr / plants and 0-14-28 days).

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.
