Effect of Row-spacing and Weed Management Practices on Growth and Yield of Sweet Corn (Zea mays L. saccharata)

The application of various conditioners in agriculture is one of the management practices used to improve soil quality and plant growth and development. The aim of this study was to assess the effect of a multi-component conditioner on the selected soil properties and maize (Zea mays L.) growth and yield. The effect of a conditioner on a set of soil properties and maize growth and yield was studied in one-year experiments carried out at three study sites, which were under a conventional tillage system. All of the study sites were located on farms in three geographic mezoregions in the Kuyavian-Pomeranian Region (Midwestern Poland). The studied soils were Haplic Luvisol (Janocin and Kobylnica) and Albic Luvisols (Krukówko) that were composed of sandy loam. A one-way analysis of variance (ANOVA) was used to determine the effect of a conditioner Solactiv on the soil and plant properties. The conditioner significantly affected the soil enzyme activities such as dehydrogenase (DHA), fluorescein sodium salt hydrolysis level (FDAH) and carboxymethylcellulose cellulase (CMC—cellulase); wherein the last one increased by about 16–20%. The application of Solactiv also increased the available K content (about 11%) but not the content of the microbial biomass C and N. Total porosity (TP), which was significantly higher in the soil treated with conditioner than in the control soils, increased the available water capacity (AWC) (about 2.2%). The higher AWC in the treated soil indicated the greater contribution of the mesopores in the TP (about 4%). A significantly higher readily available water capacity (RAWC) and small pores available water capacity (SAWC) was determined in the treated soils compared to the controls. Of the plant properties, only plant height, fresh cob biomass (BBCH 87–89) and fresh plant biomass (BBCH 84–85) were significantly increased by the conditioner. The application of Solactiv is considered to be a promising approach for developing sustainable agriculture by improving the soil’s biological activity and water-related properties.

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.
