Abstract

Soybean consumption here in Indonesia continues to increase each year that is notaccompanied by an increase in soybean production. One way to increase soybeanproduction by using improved varieties. The purpose of this study were (1) Estimating thevalue of the diversity of phenotypes soy F6 generations from crosses between Wilis x Mlg2521,(2) Estimating the heritability estimates soybean F6 generations from crosses Wilis x Mlg2521,(3) Know the numbers expectation of F6 generation crosses Wilis x Mlg2521. The researchwas conducted from March 2014 until June 2014 at the Land Lab Lampung StatePolytechnic and observations made in Laboratory of Seed and Plant Breeding, University ofLampung. Soybean seeds used were F6 generation zuriat from Wilis x Mlg2521, Wilis andMlg2521. The treatment laid out in a randomized block design, 2 replications. The resultsshowed that (1) The diversity of phenotypes population F6 for characters date of flowering,harvesting age, plant height, number of productive branches, total number of pods plant,weight of 100 grains, grain weight plant and number of seeds plant including all the broadcriteria, (2) The value of heritability estimates the population F6 for characters date offlowering, harvesting age, plant height, number of productive branches, total number ofpods plant, weight of 100 grains, grain weight per plant and number of seeds plantbelonging to the high criteria, (3) Number expectations of the population F6 is 7-64-1-8 and7-64-1-3.Keywords: heritability, phenotypic variance, soybean

Abstract

The research was conducted in February to June 2015 in the District of Rajabasa Raya, Bandar Lampung. Research used design of randomized perfect group design with five dosages of compound NPK fertilizer (16:16:16), i.e., 0, 25, 50, 75 and 100 kg/ha applied at R1 (early Flowering) and repeated three times. Homogeneity was tested with Bartlet and the addition data was tested with Tukey, and analysis of kind (if applicable). Mean separation test used orthogonal polynomial on the level of confident 5%. The results showed that application of compound fertilizer NPK 16:16:16 increases soybean yield (t/ha) and nutrient efficiency. However, NPK applications have no effect on plant height, plant dry weight, number of total branches, number of productive branches, total number of pods, and weight of 100 grains of soybean seeds. Dosing up to 100 kg/ha of NPK compound increase soybean yield but still shows a linear graph Keywords: soybean, early flowering (R1), NPK fertilizer, NPK dose.

Abstract

Gladiolus is a potential ornamental plant to be widely developed because its high aesthetic value. Generally, gladiolus is propagated vegetatively by using tuber that called corm. There are some problems in gladiolus vegetative propagation, which is corm has a dormancy period and produces only one to two corms for each gladiolus plant. The effort that can be done to solve these problems is to provide benzyladenine to gladiolus corm. This study aims to determine the response of four varieties of gladiolus (Gladiolus hybridus L.) that soak to benzyladenine in increasing the growth of shoot and corm production. This research was conducted in Bandar Lampung in 2017. The treatment was designed factorially (4 x 4) using Randomized Block Design. The first factor was the varieties of gladiolus ie Anisa, Clara, Nabila, and Nurlaela. The second factor was the 100 ppm concentration of benzyladenine in repeating ie first, second, third, and fourth soaking. Data analysis was tested by Least Significant Difference (LSD) test at 5% level. The results showed that (1) from four gladiolus corm varieties, Nabila produced the highest number of shoots at 10,34 shoots, while the variety that produces the highest number of corm was Clara at 5,71 corms, (2) the benzyladenine that used up to four times for soaking the corm resulted the same response in increasing growth of shoot and corm production of four gladiolus varieties, (3) the response of each gladiolus varieties didn’t depend on how many times that benzyladenine used to soak the corm in increasing the growth of shoot and corm production of four gladiolus varieties.
