Respons on growth and yield of soybean by giving mycorrhiza and use of seeds size in saline soil. Grobogan variety has advantages advantages flourescent, large pods and pod maturity simultaneously. Mycorrhiza is an association between certain fungi with the roots of the plant by forming a complex tangle of interactions. Saline soil is soil containing soluble salts are large enough for the growth of most plants such as hydrochloric or sulfuric. The aim of this research was to know response on growth and yield of soybean by giving mycorrhiza and use of seeds size in saline soil. Research conducted at the field experiment of Tanjung Rejo village Percut Sei Tuan, Deli Serdang on March-August 2012, using a randomized block design factorial with two factors and six replications. The first factor was grobogan variety seeds size, large seeds (13-17 g/100 seeds) and small seeds (8-11g/100 seeds). The second factor was Mycorrhiza (0 and 10 g/plant). The results showed that seed size were significantly different to plant height, number of branches, flower initiation, degree of infection, harvesting age, number of fill pods per plant and seed production per plant. Mycorrhiza were significantly different to number of branches, degree of infection. Interaction between the seeds size and mycorrhiza did not give significant effect for all parameters. Keywords: soybean, mycorrhiza, saline soil

The use of Central Composite Rotatable Design (CCRD) to determine the response surfaceyield at maize not yet a lot of checked, for that an research have been conducted in UPT BBITanjung Selamat, Regency of Deli Serdang, Province of North Sumatra with the land height ± 25 mabove sea level, at May 2012 - August 2012.The design was used is randomized block design withtwo factors, the first factor is two varieties (Bisma and SHS-4) and the second factor is fertilizerNK (the dose of NK determined from CCRD). Parameters measured were: plant height, the numberof leaf, the number of leaf above cob, the time of tasselling, the time of silking, the time ofharvesting, the rate seed filling, cob lenght, cob diameter, the number of lines per cob, the numberof seeds per cob, weight of 100 seeds and production of dry seeds. The results showed that thevarieties significantly on plant height, the number of leafs, the time of harvesting and dry seedsproduction. Fertilizer sigificantly on production of dry seeds. Interaction of varieties and fertilizerNK significantly on production of dry seeds.

attempts to do that is the use of high yielding varieties. This study aimed to determine the effect of four doses of Trichoderma extent on the growth and production of some onion varieties, which have been implemented in Simalingkar, excl. Tuntungan Field from May to August 2012. This study used a randomized block design factors ie double dose Trichodema first factor with 4 levels, namely 0 g (control), 1 g , 2 g , 3 g dose. The second factor is that varieties: Medan, Bali Karet, Maja. The data obtained were analyzed using analysis of variance, followed by Test Honestly Significant Difference The results of data analysis showed that the varieties differ significantly in plant height, number of leaves, number of cloves per sample, cloves per bulb diameter. Dose Trichoderma significantly different height and dry weight of plants per plot. Interaction between Trichoderma doses and varieties have significantly influenced all parameters. Keywords: Onion, Trichoderma dose, varieties

EVALUASI KARAKTERISTIK BEBERAPA VARIETAS KEDELAI (Glycine max L.Merill) HASIL MUTASI KOLKISIN M2 PADA KONDISI NAUNGAN Fitra Ramadhani Fitra Ramadhani; Lollie Agustina P.Putri; Hasmawi Hasyim

Many potential field is able to be cultivated, which is under the canopy of the plantationand one of the breeding program that can be used obtaining cultivars or varieties are mostlydone by the tecknical breeding mutation. F that,an experiment had been conducted in or hefield of research USU, Medan (+ 25 m asl.) In February-June 2012th by using non-factorialrandomized block design. The results of experimental study that the action plan in severalvarieties had significant effect on flower age, harvesting time, 100 seed weight, theproduction per sample and the production per plot. Value estimate of heritability range from0.12-1. The coefficient of genotypes variations are about 4.64-38.5 and coefficient ofphenotypic variation are about 6.93-38.89. No significant correlation values for allparameters.
