[EFFICIENCY OF LAND USE IN MULTIPLE CROPPING SYSTEM WITH VARIOUS CORN PLANT AND MUNG BEAN VARIETIES]. This study aims to find out the precise planting distance of corn with mung bean varieties that are suitable for increasing the efficiency of land use in terms of ecology and agronomy. Research has been carried out in the agricultural land in September 2018-January 2019 using a split-plot design. The main plot of planting spacing of corn which is 60 cm x 30 cm, 90 cm x 30 cm, and 120 cm x 30 cm, subplots ie mung bean varieties (Kutilang, Vima-1, Vima-2, Vima-3). As a comparison of intercropping systems, monocultures are cultivated by corn and mung beans. The results showed that in general intercropping of maize and mung bean NKL> 1, ecologically and agronomically efficient. However, this efficient level can be distinguished based on the spacing of corn and mung bean varieties. The best ecological efficiency at 120 cm x 30 cm corn spacing, while the best agronomic efficiency in Virna-3 mung bean varieties.

Genetic variability is a measure of the variation in plant performance caused by genetic factors. if the variability of plant character is attributable to genetic roles then the variability will be inherited in the next generation. Heritability is a genetic parameter used to measure the ability of a genotype in plant population to transmit its character. Heritability in a broad sense is defined as the ratio between genotype variance and phenotype variance. This study aimed to estimate the values of genetic variability and heritability of growth and yield of 26 plant genotypes tomato. The experiment was conducted from August to December 2016 in Wirehouse, Faculty of Agriculture, University of Bengkulu. The design used in this study was Randomized Complete Block Design (RCBD) with one factor which were 26 tomato genotypes and were repeated three times. Each plant was observed according to the variability and heritability guidelines for the observation variables. The results showed that the growth component of tomato plants that have wide genetic variability and high heritability of the broad sense was found in the characters of plant height, whereas the yield component were found on fruit diameter , crack fruit, and nonmarketable fruit. Selection of tomato plants should be directed to the characters of plant height, fruit diameter, the number of crack fruit, and non-marketable fruit. Akta

Tomato is a high nutritional value fruit vegetables. Genetic variation is valuable plant breeding material which can be measured in terms of yield potential. This study aimed to compare the growth and yield components of 16 tomato genotypes in the lowlands. The experiment was conducted in Medan Baru Experimental Station of, Faculty of Agriculture, University of Bengkulu, with the elevation of 10 m above sea level. This was performed from September 2013 to January 2014. The experiment was set in a completely randomized design with a single factor of 16 tomato genotypes with 3 replications acounting to 48 experimental units, each of which consisted of 2 plants. The sixteen genotypes tested were Mirah, Berlian, CIN 06, SU, Kudamati 3, Lombok 3, Lombok 4, Makassar, Aceh 3, Aceh 5, Ranti Situbondo, Ranti, Situbondo Gelombang, Situbondo, Kemir, Meranti 2, Gondol Lonjong. There were significant differences in plant height, stem diameter, number of leaves, stomatal density, flowering age, harvest age, fruit diameter, fruit sweetness, fruit hardness, total fruit weight, fresh weight, and dry weight. Based on total fruit weight. The genotypes potentially cultivated in the lowlands are Ranti, Situbondo Gelombang, Kudamati 3, Situbondo, and Makassar.

Soybeans are the third most important commodity after rice and corn. Soybeans are also a commodity rich in protein. Soy serves as a very important source of vegetable protein to improve people's nutrition because in addition to being safe for health is also relatively cheap compared to animal protein sources. Ultisol has a wide distribution but has constraints to be used as a medium of cultivation plants. The addition of some types of ameliorating or soil reformers such as chicken manure, cow manure, and composting oil palm bunches (OPB) is expected to overcome ultisol fertility. The purpose of this study was to compare the influence of varieties on the growth and component of soybean crop yields in Ultisol, compare the influence of ameliorating type on the growth and component of soybean crop yields in Ultisol, and get the interaction between the type of varieties with the type of amelioration to the growth and components of soybean crop yields in Ultisol. The research was conducted from February to May 2019 in the experimental garden of Integrated Agricultural Zone of the Faculty of Agriculture UNIB Medan Baru, Bengkulu City. This study used a Complete Randomized Design (CRD) that was compiled factorially with 3 times. The first factor is the variety type Anjasmoro and Gepak Kuning, the second factor of amelioration type is control (without amelioration), chicken manure 15 tons ha-1, cow manure 15 tons ha-1, husks burn 15 tons ha-1, and compost oil palm bunches (OPB) 15 tons ha-1. The results showed that the Gepak Kuning variety showed better growth than the Anjasmoro variety while the Anjasmoro variety showed better results than the Gepak Kuning variety. Chicken manure is the best type of amelioration compared to cow manure, rice husks, and compost OPB against the growth and component of soybean yields in Ultisol, and there is interaction in the Gepak Kuning variety with chicken manure amelioration and compost OPB.

This research was conducted in Beringin Raya Sungai Hitam Village, Muara Bangkahulu Subdistrict, Bengkulu City from January to April 2016.  The research aims to compare the growth and yield of 9 lines of soybean expectation with 2 varieties of comparison (Tanggamus and Demas 1) on sandy land. The design used in this study was Completely Randomized Block Design (RAKL) using a single treatment factor of 11 soybean genotypes consisting of 9 lines of expectation (G4AB, G2BB, G1DB, 13 ED, 14 DD, 19 BE, 25 EC, G511H / Anj-2-10, and G511H / Anj-1-3) and 2 varieties of comparison (Tanggamus and Demas 1), each treatment was repeated four times to obtain 44 experimental units. Variables that significantly affect the F test at 5% level, followed by cluster analysis of Scott-Knott at 5% level. Of the 9 lines of expectation tested only 13 ED lines, 14 DD, and 25 EC had a number of comparable books comparable to the comparison varieties (Tanggamus and Demas 1). The comparative varieties had moderate flowering, deep harvest age, highest plant height, number of productive branches and the largest number of fertile books compared to the 9 tested lines. Density 13 ED, 14 DD, 25 EC has a number of pods of content comparable to the comparison varieties. The G511H / Anj-2-10 strain has more number of seeds per pod than the comparable strain / variety tested. The ED 13 line has a seed weight per plot proportional to the comparison varieties (Tanggamus and Demas 1), but is higher than the expected line of test. While the 19 BE strain has a weight of 100 seeds higher than the other strains / varieties tested
