Abstract

Sorgum belum banyak ditanam di daerah Sumatera Utara, sehingga perlu diteliti untuk mengetahui kemampuannya beradaptasi pada lingkungan yang berbeda. Penelitian ini bertujuan untuk melihat kemampuan adaptasi enam varietas sorgum dengan menanam sorgum pada dua kondisi lingkungan dan ketinggian tempat yang berbeda, yaitu di dataran rendah dan dataran tinggi. Penelitian ini dilakukan di dataran rendah dan dataran tinggi, yaitu Lubuk Pakam (200 mdpl) dan Tongkoh Berastagi (1450 mdpl). Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) non faktorial, yaitu varietas sorgum yaitu Numbu, Super 1, Super 2, Soper 7, Soper 9 dan Suri 4 dengan empat kali ulangan. Parameter yang diamati adalah karakter morfologi, karakteristik stomata dan kandungan klorofil. Hasil penelitian menunjukkan bahwa semua tanaman di Lubuk Pakam lebih tinggi dibandingkan dengan tanaman sorgum di Berastagi dimana tanaman tertinggi terdapat pada varietas V3, Super 2, diikuti oleh Super 1 dan Soper 9. Jumlah klorofil a, b dan total klorofil tidak dipengaruhi secara nyata oleh perbedaan varietas, baik di dataran tinggi maupun dataran rendah. Namun demikian, terdapat perbedaan pola respon tanaman dalam menghadapi lokasi lingkungan yang berbeda melalui jumlah klorofil a dan klorofil b.

Abstract

Wheat is a cereal crop that can grow well in tropical areas only at high altitudes. However, the limited area of the highlands means that wheat development is directed at the lowlands, so plant breeding efforts are needed to obtain genotypes that are adaptive in the lowlands, one of which is through gamma ray irradiation. This research aims to identify the performance of agronomic characters of several wheat genotypes resulting from gamma irradiation planted in the lowlands. This study used a Randomized Block Design (RBD) with 2 factors, namely the first factor was wheat variety (Dewata/L, Basribey/I, and G-21/F) and the second factor was irradiation dose (0 Gy, 100 Gy, 200 Gy and 300 Gy). The data analyzed using F test at 5%. The treatment means were further compared and separated by using the Duncan Multiple Range Test (DMRT) at 5%. The research results showed that the wheat variety treatment had a significant effect on plant height and leaf area of wheat, while the gamma ray irradiation treatment and the combination of the two treatments had no significant effect on all parameters observed, but showed diversity in agronomic characters.

Abstract

Wheat is the largest cereal food in the world's staple food supply. The expansion of the wheat crop needs to be done through extensification efforts in the lowlands to increase domestic production. The main obstacles faced in the lowlands are the high air temperature and the intensity of sunlight. The research objective was to provide adaptive wheat mutant in the lowlands, especially in North Sumatra. The seeds of 3 varieties of wheat: Dewata, Basribey and G-21 were treated with gamma irradiation with a dose 100, 200, 300, 400, 500, and 600 Gy. Each treatment was repeated three times. The highest percentage of germination and vigor index due to the combination of treatment of wheat varieties with gamma rays was the combination of Dewata and 200 Gy which was significantly different from Basribey and G-21. Gamma irradiation treatment of 100 Gy on the three mutant wheat varieties showed differences in plant height, namely the G-21 variety, followed by Dewata and Basribey. The number of productive tillers showed significant variation between the gamma ray treatments for each mutant wheat genotype and the most productive tillers were at a gamma ray dose of 100 Gy for all wheat genotypes. The 100 Gy gamma ray treatment caused the number of seeds of the Dewata variety to be much higher than that of Basribey and G-21. The mutants obtained with the desired characters are the basic materials in assembling new superior varieties of wheat that are adaptive in the lowlands.

Abstract

The demand for butternut squash which continues to increase every year makes farmers try to increase their production, one of which is by applying biological and organic fertilizers. This study aims to determine the response of growth and production of butternut squash to the application of mycorrhiza and quail manure. This study used a randomized block design with 2 factors and 3 replications. The first factor was the application of mycorrhiza which consisted of 3 levels, namely: 0, 2.5, and 5 g/plant, while the second factor was quail manure which consisted of 4 levels, namely: 0, 1, 2 and 3 kg/plot. The results showed that the application of mycorrhizae had a significant effect on fruit length and fruit weight. The application of quail manure had a significant effect on increasing fruit weight. The interaction of mycorrhizae and quail manure did not significantly affect all observed parameters. Although it had no significant effect, the application of mycorrhiza and quail fertilizer was proven to increase the growth and production of butternut squash compared to the control (without the application of mycorrhiza and quail manure). The combination of mycorrhizal 2.5 g/plant and quail manure 1 kg/plot could increase butternut squash production.
