Sari. Jagung adalah serealia penting di Indonesia yang bernilai ekonomis dan strategis untuk dikembangkan sebagai bahan baku pangan (food), pakan (feed), dan minyak (fuel). Varietas jagung yang toleran terhadap intensitas naungan merupakan solusi tepat untuk meningkatkan produksi jagung melalui pemanfaatan lahan agroforestri. GGE biplot adalah model untuk visualisasi dan interpretasi data hasil pengujian genotipe pada lingkungan berbeda. Visualisasi aspek genotipe (G) dan lingkungan (E), dan hubungan keduanya (GXE) digambarkan sebagai biplot. Tujuan adalah untuk seleksi genotipe jagung toleran naungan pada sistem agroforestri. Penelitian dilaksanakan pada Maret-Agustus 2014 di Kebun Percobaan Cimalaka Sumedang menggunakan Split Plot Design diulang 2 kali. Data dianalisis menggunakan metode GGE biplot.  Berdasarkan analisis scatter plot DR-21 menunjukkan galur yang memiliki umur berbunga tergenjah di lingkungan tanpa naungan; sementara pada lingkungan naungan adalah M6DR 4.7.2. Pada bobot pipil, DR-14 memiliki bobot tertinggi pada kondisi tanpa naungan, dan mutan M6DR 5.5.1 memiliki bobot tertinggi pada kondisi naungan, mutan M6DR 16.5.15 merupakan genotipe yang memiliki nilai terendah pada lingkungan naungan dan tanpa naungan. Berdasarkan analisis rangking plot menunjukkan bobot tongkol,  genotip DR 10, dan DR 4 merupakan genotipe yang memiliki nilai tertinggi pada lingkungan naungan dan tanpa naungan, mutan M6BR-153.10.2 merupakan genotipe yang memiliki nilai terendah.  Pada umur berbunga mutan M6DR 14.2.1, M6DR 5.4.1, M6DR 14.3.11 dan  M6DR 7.1.7 merupakan genotipe yang memiliki umur berbunga tergenjah pada kedua lingkungan.Kata kunci: jagung, toleran naungan, model GGE biplot, sistem agroforestri, albizia  Abstract. Corn is an important cereal in Indonesia that is of economic and strategic value to be developed as a food ingredient, feed and fuel. Corn varieties that are tolerant of shade intensity is the right solution to increase corn production through the use of agroforestry. GGE biplot is a model for visualizing and interpreting data from genotype testing in different environments. Visualization of aspects of G x E and their relationship are described as biplot. The aim was to select corn tolerant in agroforestry. The study was conducted in March-August 2014 in the Experimental Field Cimalaka Sumedang, used Split Plot Design and repeated 2 times. Data were analyzed using the GGE biplot. Based on a scatter plot analysis showed that DR-21 have flowering at shorter time in a non-shade environment; while in the shade environment was M6DR 4.7.2. On grain weights, DR-14 line has the highest weight in non-shade conditions, and M6DR 5.5.1 mutant has the highest weight in shade conditions, while M6DR 16.5.15 is the genotype which has the lowest value in shade and without shade. Based on the ranking plot analysis showed cob weight, DR 10, and DR 4 were genotypes that have the highest values in two conditions, while M6BR-153.10.2 mutants were genotypes which have the lowest value in two conditions. On  flowering, M6DR 14.2.1, M6DR 5.4.1, M6DR 14.3.11 and M6DR 7.1.7 were genotypes that have shorter time in both environments. Keywords: corn, shade tolerant, GGE biplot, agroforestry, albizia.

Malapari (Pongamia pinnata) is a potential plant for biodiesel and has the ability to grow on marginal land. Malapari cultivation has not yet been carried out due to low economic value. Agroforestry crop patterns are expected to provide intermediate results so that people would be interested in planting malapari. Planting on coastal land requires the right technology to produce optimal growth. This study aims to determine the effect of malapari cropping patterns and evaluate biological fertilizer application in the seedling phase after planting in the field. The research uses a split plot design (Split Plot Design) with the main factors that are the pattern of malapari planting and sub-plots that are the type of application of biofertilizer. The results obtained from the study showed that the interaction of cropping pattern treatment and biofertilizer application did not give significant growth to malapari; the combination of the application of organic manure, Trichoderma spp and mycorrhiza bio-fertilizers in the nursery yielded the largest malapari diameter growth after planting in the field at the age of 3 years.

Java turmeric (Curcuma xanthorrhiza Roxb.) is cultivated as a secondary crop, resulting in variable rhizome quality which can be increased by suitable cultivation methods. This study investigated the effect of different cultivation methods on the rhizome yield of Java turmeric. Different fertilizer treatments(none, organic, inorganic, and semi-organic fertilizer), three groups of rhizome seed size (small (50–80 g), medium (100–150 g), and large (200–250 g)) and three groups of harvesting age (eight, ten, and twelve months after planting) were evaluated in a split plot design experiment. Results show that large rhizome seed size together with organic fertilizer treatment increased secondary rhizome production, yielding the highest number, weight and diameter. As high levels of starch in the primary rhizome are crucial for growth of the plant, the use of large rhizomes for propagation is indicated in Java turmeric cultivation. The highest weight and number of primary rhizomes were yielded when plants were harvested twelve months after planting.

[UTILIZATION OF MICROBE TO INCREASE GROWTH AND YIELDS OF SOYBEAN IN COASTAL LAND. This study aims to obtain the right combination of varieties and biofertilizers to increase soybean productivity on Bengkulu coastal land. The research was conducted from March to July 2017, located in Beringin Raya Village, Muara Bangkahulu Sub-District, Bengkulu. The study was conducted with a split-plot design which was repeated three times. The main plot is two soybean varieties (Grobogan and Wilis). The subplots are two types of biological fertilizers, arbuscular mycorrhizal fungi, and phosphate solvent fungi. The results showed that the results of the seed weight of the Grobogan variety (equivalent to 3.38 tons/ha) were significantly higher than the Wilis variety (equivalent to 2.72 tons/ha). However, the Wilis variety showed an increase in seed weight (equivalent to 1.12 tons/ha) higher than the Grobogan variety (equivalent to 0.61 tons/ha) according to the description of each variety. The combination of arbuscular mycorrhizal fungi and phosphate solvent fungi showed superior performance than arbuscular mycorrhizal fungi fertilizer or phosphate solvent fungi. The interaction of Grobogan varieties with a combination of arbuscular mycorrhizal fungi and phosphate solvent fungi produced the highest seed weight (equivalent to 3.52 tons/ha) which was statistically similar to the interaction of Grobogan varieties and arbuscular mycorrhizal fungi (equivalent to 3.45 tons/ha). The economics of resources using arbuscular mycorrhizal fungi are not required to be combined with phosphate solvent fungi.

Split-plot design is a very popular experimental design in analyzing factorial treatments in horticultural experiments. Two different sizes or types of experimental units are assigned to main plot and the split-plot treatments. The SAS procedure GLM with the TEST option is commonly used to analyze the split-plot data by assigning the correct error term to test the main plot factor. In SAS GLM, no option is available to compare the two main factors within a split-plot factor. The CONTRAST tests and LSMEAN comparisons are valid only for comparing split-plot factors within a main plot treatment. The main factor standard error provided by the LSMEAN option is also incorrect. The new PROC MIXED procedure available in SAS 8.08 or above can be used to correct these problems in split-plot analysis. The analysis of split-plot experiments using the PROC MIXED is presented here.

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during July to November 2016 to investigate the performance of separated tillers of hybrid rice variety Dhani Gold. The experiment comprised three times of tiller transplantation viz. 3, 4 and 5 week aged tiller seedlings and four levels of number of tiller seedlings transplanted hill-1 viz. 2, 3, 4 and 5 tiller seedlings hill-1 laid out in a split plot design with 3 replications. The highest plant height was obtained when 3-week aged tiller seedlings were transplanted at the rate of 3 tiller seedlings hill-1. The highest number of total tillers hill-1 and number of effective tillers hill-1 were found when 3-week aged tiller seedlings were transplanted with 5 tiller seedlings hill-1. The highest grains panicle-1 was obtained when 4-week aged tiller seedlings were transplanted with 5 tiller seedlings hill-1. The highest grain yield was found when 3-week aged tiller seedlings were transplanted with 5 tiller seedlings hill-1. The lowest grain yield was found when 5-week aged tiller seedlings were transplanted with 2 tiller seedlings hill-1 in hybrid rice variety Dhani Gold. Based on the findings of the present study it may be concluded that 3-week old tiller seedlings of Dhani Gold should be transplanted at the rate of 4 or 5 tiller seedlings hill-1 for higher yield. Thus present study confirms the potentiality of growing hybrid rice from separated tillers in case of unavailability of seedlings or to minimize the seed cost of high value hybrid rice seeds.
