Abstract

This study aims to examine the effect of the interaction between the administration of biophosphate and the use of local Jakar potato cultivars on the growth, yield and sugar content of sweet potato plants. The research method uses (RAK) 4 times. The 1st factor was Biophosphate (B), consisting of two levels: b1 (100 kg/ha biophosphate) and b2 (200 kg/ha biophosphate). The second factor was Sweet Potato Cultivar (K), consisting of three levels: k1 (cilembu), k2 (maja) and k3 (brass and white). Differences in treatment means were tested using Duncan's multiple range test at the 5% level. The results showed that bophosphate and sweet potato cultivars had no interaction effect. Phosphate administration did not have a different effect on all growth and yield variables of sweet potato plants. The use of cultivars had no different effect on growth, yield and sugar content.

Abstract

Budidaya kedelai hitam di Indonesia tergolong masih rendah. Usaha yang bisa dilakukan yaitu mengembangkan kedelai hitam dengan perakitan varietas tanaman pada kegiatan pemuliaan tanaman. Pemulia Universitas Padjadjran telah menghasilkan 13 galur kedelai hitam, tetapi belum diketahui karakteristiknya. Karakterisasi adalah kegiatan mencari sifat khusus yang ada sebagai pembeda. Tujuan dari penelitian ini adalah untuk mengetahui karakter masing-masing tanaman. Pengamatan dilakukan pada karakter kualitatif dan kuantitatif sebanyak 21 pengamatan berdasarkan UPOV 1998. Percobaan dilakukan di Desa Sanca Kecamatan Gantar Kabupaten Indramayu, dengan 13 galur uji dan 2 cek yaitu Detam 1 dan Mutiara 3 yang diulang 3 kali ulangan dengan metode RAK (Rancangan Acak Kelompok) non faktorial dan diuji lanjut dengan Uji DMRT Taraf 5 %. Hasil penelitian menunjukan perbedaan pada beberapa karakter diantara galur pada karakter intensitas hipokotil, dan bentuk daun. Pada karakter intensitas hipokotil BS 111, BS 140, BS 64, BS 79 memiliki intensitas hipokotil sangat lemah, BS 141 memiliki intensitas hipokotil lemah, BS 87, Detam 1 dan Mutiara 3 memiliki intensitas sedang dan BS 72, BS 100, BS 77 memiliki intensitas hipokotil yang sangat kuat.

Abstract

The purpose of this research was to evaluate the influence of soybean cultivar combinations and biofertilizer dosages on the growth and yield of soybean plants during the rainy season. The analysis results indicated that these combinations did not have a significant effect on the growth and yield of the plants. The variations among treatments were predominantly influenced by the choice of cultivar. The use of biofertilizers enhanced nutrient availability for the plants but did not consistently yield significant results. Rainy season and other environmental factors also affected plant growth. Cultivar variations and genetic factors played a role in yield variations as well. The use of biofertilizers provided benefits for soil structure and microbial activity. In terms of pod and seed quantities, the Deja 2 cultivar with biofertilizer dosages of 0 g/kg and 10 g/kg demonstrated the highest yields. There were no significant differences in root dry weight across all treatments, while the highest shoot dry weight was observed in the Grobogan cultivar with a biofertilizer dosage of 0 g/kg. In terms of weight per 100 seeds, the Grobogan cultivar with biofertilizer dosages of 0 g/kg, 5 g/kg, 10 g/kg, and 15 g/kg exhibited the highest weights. This research indicates that genetic factors, environment, and biofertilizer dosages play a role in the growth and yield of soybean plants. In terms of the number of soybean plant branches, some treatments showed the best results, but the impact of biofertilizer dosages was not significantly observed. Regarding root dry weight, there were no significant differences among the treatments, possibly due to suboptimal translocation of photosynthetic products to the roots resulting from high rainfall. However, shoot dry weight tended to increase in treatments with high rainfall conditions. The parameters of pod fill count and seed count per plant were also influenced by the combination of cultivars and biofertilizer dosages. Some treatments exhibited higher yields, particularly in the combination of the Deja 2 cultivar with a biofertilizer dosage of 0 g/kg. Â
