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.

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).

This study was carried out to investigate the effects of different sowing times on duration of tasselling, plant height, first ear height, ear length, ear diameter, number of ears per plant, fresh ear yield with husk, fresh ear yield unhusked, and marketable number of ears of different sweet corn (Zea mays L. saccharata Sturt.) varieties in Diyarbakır between the years of 2010-2012. The trial was conducted as split plots in randomised complete blocks with three replications. The main plots were sowing times, and the sub-plots were varieties. The trials were carried out at eight different sowing times (1 April, 15 April, 1 May, 15 May, 1 June, 15 June, 1 July and 15 July) with ‘Merit’, ‘Jubilee’, ‘Lumina’, ‘Vega’ and ‘Sakarya’ composite sweet corn varieties. From the variance analysis of the three-year combined average, the duration of tasselling, plant height, first ear height, ear length, ear diameter, number of ears per plant, fresh husked ear yield, fresh unhusked ear yield and marketable ear number were statistically significant for sowing times and varieties. According to the sowing time × variety interaction, except ears per plant and first ear height values, all other traits were significant. The fresh husked and unhusked ear yields varied between 8541.7-19396.8 kg ha-1 and 5065.0-13485.7 kg ha-1, respectively. The highest fresh husked and fresh unhusked ear yields were obtained from the 15 April sowing time of ‘Vega’ variety. The results state that optimal sowing dates for different varieties of sweet corn could be from 1 April to 1 May, and the most suitable variety to be planted is ‘Vega’ in Diyarbakır conditions.
