Abstract

Buah pepaya sebagai sumber vitamin, ketersediaannya dalam bentuk yang sesuai dengan permintaanmerupakan salah satu tujuan pemuliaan tanaman pepaya. Tujuan penelitian adalah mengetahui efek heterosis danheritabilitas pada komponen ukuran buah pepaya F1. Penelitian dilakukan di Kebun Percobaan Aripan, Balai PenelitianTanaman Buah Tropika, Solok dari bulan Januari 2003 sampai Desember 2004. Rancangan percobaan yang digunakanadalah acak kelompok dengan 5 perlakuan genotip tetua, yaitu Semangko-01, Meksiko-01, Py-Rif- 90, Solo-01, danSmn-01 dengan 4 ulangan. Untuk memperkecil bias, data diambil dari 3 tanaman contoh/perlakuan/ulangan. Penelitiandilakukan dalam 2 tahap, yaitu tahap I (tahun 2003) dilakukan penanaman 5 tetua sampai panen dan tahap II (tahun2004) dilakukan penanaman 10 F1 sampai panen. Hasil penelitian menunjukkan bahwa nilai heterosis pada F1 yangberbeda menurut uji t 5% diakibatkan oleh aksi gen dominan negatif tidak sempurna dan dominan positif tidaksempurna. Nilai heritabilitas dalam arti luas untuk karakter bobot, panjang, dan lingkar buah berturut-turut adalah0,92 g, 0,91 cm, dan 0,75 cm. Tetua Semangko-01 yang mempunyai ukuran buah tergolong besar dan Py-Rif-90dengan ukuran buah tergolong kecil dapat digunakan untuk pembentukan hibrida dengan bobot, panjang, dan lingkarbuah yang berukuran sedang (konsumsi keluarga kecil).ABSTRACT. Sukartini, T. Budiyanti, and A. Sutanto. 2009. Heterosis Effect and Heritability on Fruit SizeComponents of F1 Papaya. The objectives of this study were to determine effect of heterosis and heritability of fruitcharacters of F1 papaya. The research was conducted at Aripan Field Station of Indonesian Tropical Fruits ResearchInstitute from January 2003 until December 2004. A randomized block design was used in this research where thetreatments was the genotypes, namely Semangko-01, Mexico-01, Py-Rif- 90, Solo-01, and Smn-01, with 4 replicationsand 3 samples of papaya plant/treatment/replication. The research was done in to 2 steps: first step (2003) 5 parents wasplanted until harvest and second step (2004) 10 F1 was planted until harvest. The results showed that heterosis valuesin F1 population showed significant different at 5% level of t test due to the negative and positive partial dominancegene action. In general, heritability for weight, length, and circumference of fruit characters were 0.92, 0.91, and0.75 respectively. Parental Semangko-01 with big size of fruit and Py-Rif-90 with small size of fruit can be used togenerate hybrid with medium size of weight, length, and circumference for small family consumption.

Abstract

Pepaya sangat potensial dibudidayakan di lahan rawa pasang surut, tetapi ketersediaan hara dalam tanahnya tergolong rendah. Nitrogen dan kalium merupakan hara yang relatif banyak dibutuhkan pepaya, sehingga budidaya pepaya di lahan rawa pasang surut perlu penambahan hara tersebut melalui pemupukan. Penelitian dilakukan di lahan rawa pasang surut eks proyek lahan gambut (PLG) sejuta hektar di Kecamatan Mantangai, Kabupaten Kapuas, Provinsi Kalimantan Tengah dari bulan Juni 2007 sampai April 2008. Tujuan penelitian ialah untuk mengetahui pengaruh pemberian hara N dan K terhadap pertumbuhan dan produksi pepaya. Benih pepaya yang digunakan ialah varietas Merah Delima. Penelitian disusun dengan rancangan acak kelompok  faktorial dengan tiga ulangan. Faktor I ialah takaran pupuk nitrogen yaitu 0, 125, 250, 375 g/tanaman dan faktor II ialah takaran pupuk kalium (K20) yaitu 0, 150, 300, 450 g/tanaman. Tiap unit perlakuan terdiri atas 10 tanaman. Parameter yang diamati meliputi sifat kimia tanah, pertumbuhan vegetatif, dan produksi tanaman. Hasil penelitian menunjukan bahwa  ketersediaan N, P, dan Fe di lokasi penelitian tergolong sangat tinggi, K rendah, sedangkan Ca dan Mg sangat rendah. Pemupukan N hingga taraf 375 g/tanaman tidak berpengaruh nyata terhadap peningkatan pertumbuhan vegetatif tanaman pepaya. Namun pada fase produktif (10 bulan setelah tanam), panjang buah secara nyata meningkat dengan pemberian N 250 g/tanaman. Pemberian K2O pada taraf 300g/tanaman secara nyata meningkatkan pertumbuhan vegetatif dan produksi tanaman (jumlah, bobot, panjang, dan PTT), sedangkan pemberian K2O yang melebihi 300 g/tanaman mengakibatkan penurunan pertumbuhan, produksi, dan kualitas buah. Hasil penelitian ini dapat digunakan sebagai landasan penelitian dan penyusunan rekomendasi pemupukan pepaya di lahan rawa pasang surut. Papaya has opportunity to be cultivated in tidal swamp land but the availability of its nutrient in the soil is low.  Nitrogen and potassium are the major nutrients needed by papaya, so that the nutrient should be added through fertilization. The research was conducted in tidal swamp land in Mantangai, Kapuas, Central Kalimantan Province, from June 2007 to April 2008. The objective of this research was to investigate the effect of nutrient N and K on growth and production of papaya in tidal swamp land. Merah Delima variety was used as a seed in this research. The factorial experiment was arranged in a randomized block design with three replications.The first factor was dosage of nitrogen of 0, 125, 250, and 375 g/plant and the second factor was amount of potassium (K2O) from 0, 150, 300, and 450 g/plant. Each unit of treatment consisted of 10 plants. The parameters observed include the chemical properties of soil, vegetative growth, and crop production. The results showed that the availability of  N, P, and Fe at the research location was classified as very high, whereas K was low, Ca and Mg were very low. Nitrogen fertilization up to level 375 g/plant did not significantly increase the vegetative growth of papaya plants because of its high availability of the nutrition on the soil. However, in the productive phase (10 months after planting), fruit length was significantly increased with application of N in dose 250 g/plant. Application of K2O fertilizer on 300/plant increased significantly vegetative growth and yield (number of fruit, fruit weight, fruit length, and TSS), whereas application of more than 300 g/plant decreased their growth, yield, and fruit quality. The results can be used as the basis to arrange and formulate fertilizer recommendation on papaya  which is mainly grown on tidal swamp land.

Abstract

Drought stress can cause a decrease in crop production. The development of drought stress tolerant chili varieties can be done to overcome this problem. Several methods, including the drought stress selection method in the sprouting phase, can be carried out using Polyethylene glycol (PEG-6000) stress simulation. The drought sensitivity index (ISK) or stress susceptibility index (SSI) is used to select for drought stress tolerance in plants. This research aims to determine the level of drought stress tolerance of several chili genotypes at the sprouting stage based on the drought sensitivity index. The research used a complete randomized block design with 23 local West Sumatran chili genotypes treated with drought stress at the germination stage with 15% PEG and control (0% PEG). Based on the drought sensitivity index (ISK) criteria, the results of the screening of chili tolerance to drought using five variables obtained six genotypes which were included in the tolerant category, namely genotypes (7) Tanah Datar Green Bonsai, (6) 33 Taijan, (21) Akar Solsel , (18) Lolai Chili, (1) Tali and (5) CI Sijunjung. DM-2, Bukitinggi and Dhamasraya-1 chilies have the highest total ISK score which indicates they are susceptible to drought stress at the germination stage.

Abstract

ABSTRACTWater stress disrupts plant growth, especially chili plants, which results in decreased yields, crop failure or plant death. One strategy to increase chili plant tolerance can be done through fertilization, organic fertilizer, mycorrhiza and other microorganisms. The study aims to determine the effect of several levels of water supply and organic fertilizer on the growth of curly chili varieties AKA in the early vegetative and generative phases. The study used a complete randomized block design with 12 treatments with 3 replications. The treatments are: P0. Field capacity water supply, P1. Field capacity water irrigation (FC) + 60ml cow urine, P2. Water irrigation FC + 10ml/L amiboost, P3. FC water irrigation + 15g mycorrhiza, P4. 50% FC water irrigation, P5. 50% field capacity water irrigation + 60ml cow urine, P6. 50% FC + amiboost 10ml/L, P7. 50% FC water irrigation + mycorrhiza 15g, P8. 25% FC water irrigation, P9. 25% FC water irrigation + cow urine 60ml, P10. 25% FC water irrigation + amiboost 10ml/L, P11.  25% FC water irrigation + mycorrhiza 15g. The results showed that watering with water below 50% FC reduced plant growth in the early vegetative and generative phases. This can be seen in all observed variables, decreasing significantly. The growth of plants given 100% FC water was very good, especially in the treatment of adding amiboost and cow urine. The addition of liquid organic fertilizer and mycorrhiza to plants given water below 50% KL has not been able to increase the growth of chili plants at the age of 2 months after planting.

Abstract

Chili is one of the commodities with a relatively high level of price fluctuation. The impact of climate change on the agricultural sector is the uncertainty of the dry season, which causes changes in cropping patterns due to drought. Cultivation technology and superior varieties with drought-tolerant characteristics are among the needs for increasing chili production. This activity aims to increase drought stress tolerance in local chili peppers of West Sumatra. The research was conducted from July to December 2024 in Solok, West Sumatra. This research was conducted with a Randomized Complate Block Design (RCBD) with 6 treatments of giving several doses of salicylic acid and repeated as many as 3 replicates. Salicylic acid was sprayed on chili plants aged 14 days after planting (HST) every two weeks with concentrations of 5, 10, 15 mM, as much as 20 mL per plant. The results showed that drought stress, combined with watering at 35% of field capacity, caused a decrease in vegetative and early generative growth in chili plants. Salicylic acid treatment has not been able to increase early vegetative and generative growth in drought-stressed chili plants 2 months after planting
