Abstract Most peanut (Arachis hypogaea L.) fields of the Southern Coastal Plain are treated with either vernolate (S-propyl dipropylthiocarbamate) or benefin (N-butyl-N-ethyl-a,a,a-trifluoro-2, 6-dinitro-p-toluidine) or a combination of these two herbicides to control certain weeds. The nematicide DBCP (1,2-dibromo-3-chloropropane) is also used in some fields. Field and greenhouse experiments were conducted to determine the effect of vernolate, benefin, DBCP, and Rhizobium sp. on nodulation, yield, quality, and chemical composition of ‘Starr’ peanuts. The application of herbicides, nematicide, and inoculant had no significant effect on yield, sound mature kernels, or ether extract of ‘Starr’ peanuts. The N content of the leaf and seed and the number of nodules were not affected by the treatments. Nematode infestation was low and did not affect yield. In the greenhouse studies, the application of lime, herbicides, or fertilizer did not affect certain morphological characteristics of the plant or N content of the peanut leaves. Nitrogen fertilization increased the weight of the peanut foliage.

Abstract In a three year study (1980–1982) at the Georgia Coastal Plain Experiment Station, Tifton, Georgia, the full-season Florunner and the short-season Pronto cultivars were harvested at six 10-day intervals beginning 90 days after planting. For the 3-year average, peanut (Arachis hypogaea L.) plants from Florunner harvested at 110 and each succeeding 10-day growth period up to 140 days produced greater pod yields, sound-mature kernels, large and jumbo seed, and greater calculated market value than Pronto. However, seed market grade components and maturity indexes reflecting quality and maturity were impaired when peanuts were dug too early and varied among years and growth periods.

Abstract Peanuts (Arachis hypogaea L.), cultivar Florunner, from plants inoculated with peanut stripe virus (PStV) were evaluated for chemical composition in comparison with peanuts from uninoculated plants. At harvest, seed were collected from plants which had been mechanically inoculated with PStV at emergence, or 20, 40, or 60 days after emergence and from uninoculated plants. The seed from PStV-infected plants had increases in manganese, selenium, zinc, iron, tartaric acid, raffinose, glucose, fructose, and total carbohydrate contents as compared to seed from uninoculated plants. Sucrose was increased in seed from plants inoculated with PStV at time of emergence. There was a decrease in the concentration of potassium, magnesium, protein, and total soluble phenolics of seed from plants inoculated with PStV. There were no changes in the concentration of stachyose, inositol, phosphorus, sulfur, calcium, copper, and oil.

Low Rate

Abstract The effectiveness of a low rate of lime slurry for peanut (Arachis hypogaea L.) production was evaluated on four Coastal Plain soils of southeastern Alabama. The four experimental sites were selected on farmers' fields because of their low soil pH and low exchangeable Ca. Lime was applied just prior to planting at a 560-kg/ha rate and at the recommended rate; lime sources included a slurry, an equally-fine dry limestone, and an agricultural-grade limestone. Soil pH and exchangeable Ca of the Ap horizon were measured by depth increments when crop was harvested. Lime slurry and dry lime at equivalent rates had identical effects on soil pH and peanut yields. The 560-kg/ha rate was inadequate for maximum peanut yields on Ca-deficient soils. The recommended rate of agricultural-grade limestone was more reactive than the low rate of lime slurry, and it also produced higher peanut yields.

Um ensaio foi conduzido em casa de vegetação, com solução nutritiva isenta de N, com o objetivo de selecionar estirpes de Rhizobium eficientes fixadoras de N2, quando associadas com amendoim (Arachis hypogaea L.) cultivar Tatu. Foram testadas 35 estirpes de Rhizobium sp., isoladas de quinze diferentes espécies de leguminosas tropicais, e incluído um tratamento de inoculação com solo previamente cultivado com amendoim. Das 35 estirpes testadas, doze formaram nódulos e, entre essas, sete foram eficientes fixadoras de nitrogênio. Das doze estirpes que nodularam, sete foram isoladas de leguminosas da tribo Hedysareae (à qual pertence o género Arachis) e, destas, apenas quatro foram eficientes fixadoras de nitrogênio. O peso e o número de nódulos não se mostraram como critérios adequados para avaliação da eficiência.

Peanut Cultivars

Peanut (Arachis hypogaea L.) is a food commodity that is widely cultivated in Indonesia. At present there has been no analysis of the relationship between peanut cultivars with phenetic methods based on the morphological properties of the plants. Four cultivars of Arachis hypogaea L. Tuban, Talam 1, Talam 2, and Talam 3 used in this research. Morphological characters data was analyzed by description to construct identification key. Similarity index was counted by Simple Matching Coefficient (SSm) formula based on morphological scoring. Cluster analysis was conducted by UPGMA (Unweighted Pair Group Methods using Arithmetic Averages) method to construct dendrogram. PCA (Principal Component Analysis) were performed to defined role of each morphological character in grouping of accessions with MVSP (Multivariate Statistical Program) v. 3.1 software.  The dendrogram showed that four cultivars of Arachis hypogaea L. divided into two main clusters, 4 sub-clusters. The similarity index of clusters is 0.85%.

Tujuan penelitian adalah mengkaji waktu inokulasi terbaik dan pemberian berbagai jenis mulsa organik terhadap produksi kacang tanah (Arachis hypogaea L. Var. Takar) pada lahan salin dengan tingkat salinitas 6,4 dS/m. Penelitian kali ini dilaksanakan di Desa Bulakbaru, Kecamatan Kedung, Kabupaten Jepara. Rancangan yang digunakan adalah RAK Faktorial 4 x 3 dengan 3 kelompok. Faktor pertama adalah perbedaan waktu inokulasi Rhizobium sp. yaitu T0: tanpa inokulasi, T1: inokulasi saat tanam, T2: inokulasi 7 HST, dan inokulasi 14 HST. Faktor kedua adalah berbagai jenis mulsa organik yaitu R0: tanpa mulsa organik, R1: mulsa organik jerami padi, dan R2: mulsa organik sekam padi. Parameter yang diamati adalah tinggi tanaman, jumlah daun, jumlah polong per petak, bobot polong per petak, jumlah biji per petak, jumlah bintil akar dan bobot 100 biji. Hasil penelitian menunjukkan bahwa R1 menunjukkan peningkatan rerata tinggi tanaman sebesar 62,1 cm dan T1 menunjukkan rerata jumlah bintil akar tertinggi sebesar 1,86/tanaman. Tidak ada pengaruh dan interaksi pad parameter lain. Kesimpulan yang diperoleh adalah mulsa organik jerami mampu meningkatkan tinggi tanaman dan waktu inokulasi saat tanam dapat meningkatkan jumlah bintil akar di lahan dengan tingkat salinitas 6,4 dS/m. Kata kunci : kacang tanah, salinitas, rhizobium sp, mulsa organik.
