Abstrak.  Penelitian ini bertujuan untuk mengetahui pengaruh jenis mikoriza dan populasi tanaman terhadap pertumbuhan dan hasil jagung manis, serta interaksi antara jenis mikoriza dengan populasi tanaman terhadap pertumbuhan dan hasil jagung manis. Penelitian ini dilaksanakan pada bulan November 2017 sampai Januari 2018 di Desa Blang Krueng, Kecamatan Baitussalam, Kabupaten Aceh Besar. Rancangan Penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) pola faktorial 3 x 2 dengan  3 ulangan. Faktor yang diteliti yaitu jenis mikoriza dan populasi tanaman. Faktor jenis mikoirza terdiri dari 3 taraf yaitu ; mikoriza glomus mosseae, gigaspora dan campuran. Faktor populasi tanman terdiri atas 2 taraf yaitu : satu benih dan dua benih. Hasil penelitian menunjukkan penggunaan jenis mikoriza campuran secara umum menghasilkan pertumbuhan dan  hasil  tanaman jagung yang lebih baik. Sedangkan populasi tamanan yang terbaik adalah satu tamanan. Selanjutnya Interaksi yang lebih baik terdapat  pada jenis mikoriza campuran dengan  populasi tamanan pada parameter diameter batang 15 HST dan 30 HST, berat basah akar dan berat buah berkelobot, diameter tongkol,berat buah tampa kelobot dan potensi hasil per hektar. The effect of Mycoriza Types and Number of Crop Populations on Growth and Yield of Sweet CornAbstractThis research purposes to know the effect of mycoriza types and the population of  the plants toward the growth and yield of sweet corn and the interaction between mycoriza types and the population of  the plants to the growth and yield of sweet corn. This research was carried out in November 2017 until Januari 2018 at Blang Krueng village, Baitussalam sub-district, Aceh Besar Regency and Physiology Laboratory, faculty of Agriculture, Syiah Kuala University. This research was conducted Randomized Block Design factorial pattern 3 x 2 with 3 replications. The factors studied in this research are mycoriza types and the population of  the plants. 3 types of mycoriza types are glomus mosseae mycoriza, gigaspora and the mixture of glomus mosseae and gigaspora. and 2 types of the population of  the plants are using one seed and two seed. The result of this research pointed out that the using of the mixture mycoriza type generally increased the growth and yield of sweet corn.  Whereas, the using of the population  of  the plants with one seed had showed the best result. And the better interaction is obtained in the mixture mycoriza with the population of  the plants in there after a good interaction is present in mixed mycorrhizae species with plan population on the diameter of tehstem 15 HST and 30 HST, the weight of the root base and the weight of the weighted fruit, the diameter of the cob weight of the without any weight fruit and the potential yield per hactare.

Pyroxasulfone is an experimental herbicide for use in field corn (Zea mays L.) and soybean that may have potential for weed management in sweet corn. Tolerance of eight sweet corn hybrids to pyroxasulfone applied preemergence (PRE) at rates of 0, 209, and 418 g·ha−1 a.i. were studied at two Ontario locations in 2005 and 2006. Pyroxasulfone applied PRE at 209 and 418 g·ha−1 caused minimal (less than 3%) injury in Harvest Gold, GH2041, GH9589, GSS9299, GG214, GG446, GG763, and GG447 sweet corn hybrids at 7, 14, and 28 days after emergence. Pyroxasulfone applied PRE did not reduce plant height, cob size, or yield of any of the sweet corn hybrids tested in this study. Based on these results, pyroxasulfone applied PRE at the rates evaluated can be safely used for weed management in Harvest Gold, GH2041, GH9589, GSS9299, GG214, GG446, GG763, and GG447 sweet corn.

Three agrotechnical factors (sowing time, fertilization, plant density) and the effect of two different genotypes on the yields of sweet corn was studied, in the dry and warm crop-year of 2009 on a chernozem soil in the County of Hajdúság. The experiments were carried out on the Látókép Research Station of Debrecen University. The experiment involved two sowing times (21 of April and 19 of May), six fertilizer levels (control, N30+PK, N60+PK, N90+PK, N120+PK, N150+PK) and two genotypes (Jumbo, Enterprise). Four plant density levels, 45 thousand ha-1, 55 thousand ha-1, 65 thousand ha-1 and 75 thousand ha-1 were used. In the early sowing time the highest yield was obtained with 65 thousand ha-1 plant density level and N120+PK treatment of Jumbo (18169 kg ha-1), while the maximum yield of Enterprise was 17818 kg ha-1 with 75 thousand ha-1 plant density level and N90+PK dose. In case of the late sowing time both hybrids gave the highest yield with 75 thousand ha-1 plant density level and N30 +PKtreatment, with a crop yield of 13143 kg ha-1 (Jumbo) and 14324 kg ha-1, ( Enterprise).

Topramezone is a newly introduced herbicide for use in field corn (Zea mays L.) that may have potential for weed management in sweet corn. Tolerance of eight sweet corn hybrids to topramezone applied postemergence (POST) at 0, 50, 75, 100, 150, and 300 g a.i. ha− 1 were studied at one Ontario location in 2000 and two locations in 2001 and 2002. Topramezone applied POST at 50, 75, 100, and 150 g·ha− 1 did not cause any visual injury in Calico Belle, CNS 710, Delmonte 2038, FTF 222, FTF 246, GH 2684, Reveille, and Rival sweet corn hybrids at 7 days after treatment (DAT) and caused minimal injury (less than 5%) at 300 g·ha− 1 in all hybrids. The initial sensitivity observed in these hybrids was minimal and transient with no effect on visual injury at 14 and 28 DAT. Topramezone applied POST did not reduce plant height, cob size, or marketable yield of the sweet corn hybrids included in this study. Based on these results, topramezone applied POST at the rates evaluated can be safely applied to Calico Belle, CNS 710, Delmonte 2038, FTF 222, FTF 246, GH 2684, Reveille, and Rival sweet corn.

Qualitative Characteristics

Sweet corn (Zea mays L.) belongs to the Gramineae family, var. rugosa (Bonof) convar. Saccharate (Sturt.) and can be distinguished from normal corn by presence of one or more mutant genes that affect carbohydrate metabolism in endosperm. Purpose of this research is to compare behavior of sweet corn hybrids created at SCDA Turda, but also foreign hybrids, in terms of quality elements and chemical composition, in conditions of Transylvania plateau, in two localities: Turda and Viişoara. As biological material following domestic sweet corn hybrids were chosen: ‘Prima’, ‘Estival’, ‘Deliciul verii’, ‘Dulcin’, ‘Delicios’, ‘Estival M’ and foreign hybrid ‘Jubilee’. These hybrids were also analyzed in terms of chemical composition. Weight of ‘Estival’ hybrid has the best behavior in both localities; as regards to cobs length, ‘Delicios’ hybrid has registered increases very significant positive, differences between plant height in the two localities confirm significant influence of environment on formation of this important typical qualitative characteristics, highest performances in terms of β-cryptoxanthin and zeaxanthin content, are recorded by ‘Jubilee’ in both localities, ‘Deliciul Verii’ hybrid records significant value for lutein content, also recording an important addition of carbohydrates in Turda, ‘Prima’ and ‘Estival’ hybrids recorded highest values of sucrose in both localities.
