Bambara groundnut (Vigna subterranea L. Verdc.) is considered an emerging crop for the future and known as a crop for the new millennium. The core intention of this research work was to estimate the variation of landraces of Bambara groundnut considering their 14 qualitative and 27 numerical traits, to discover the best genotype fitted in Malaysia. The findings of the ANOVA observed a highly significant variation ( p ≤ 0.01 ) for all the traits evaluated. There was a substantial variation (7.27 to 41.21%) coefficient value, and 14 out of the 27 numerical traits noted coefficient of variation CV ≥ 20 % . Yield (kg/ha) disclosed positively strong to perfect high significant correlation ( r = 0.75 to 1.00; p ≤ 0.001 ) with traits like fresh pod weight, dry pod weight, and dry seed weight. The topmost PCV and GCV values were estimated for biomass dry (41.09%) and fresh (40.53%) weight with high heritability (Hb) and genetic advance (GA) Hb = 95.19 %, GA = 80.57 % and Hb = 98.52 %, GA = 82.86 %, respectively. The topmost heritability was recorded for fresh pod weight (99.89%) followed by yield (99.75%) with genetic advance 67.95% and 62.03%, respectively. The traits with Hb ≥ 60 % and G A ≥ 20 % suggested the least influenced by the environment as well as governed by the additive genes and direct selection for improvement of such traits can be beneficial. To estimate the genetic variability among accessions, the valuation of variance components, coefficients of variation, heritability, and genetic advance were calculated. To authenticate the genetic inequality, an unweighted pair group produced with arithmetic mean (UPGMA) and principal component analysis was executed based on their measurable traits that could be a steadfast method for judging the degree of diversity. Based on the UPGMA cluster analysis, constructed five distinct clusters and 44 accessions from clusters II and IV consider an elite type of genotypes that produce more than one ton yield per hectare land with desirable traits. This study exposed an extensive disparity among the landraces and the evidence on genetic relatives will be imperative in using the existing germplasm for Bambara groundnut varietal improvement. Moreover, this finding will be beneficial for breeders to choose the desirable numerical traits of V. subterranea in their future breeding program.

As a crop for the new millennium Bambara groundnut (Vigna subterranea L. Verdc.) considered as leading legumes in the tropical regions due to its versatile advantages. The main intent of this study was to find out the high yielding potential genotypes and considering these genotypes to develop pure lines for commercial cultivation in Malaysia. Considering the 14 qualitative and 27 quantitative traits of fifteen landraces the variation and genetic parameters namely, variability, heritability, genetic advance, characters association, and cluster matrix were determined. ANOVA revealed significant variation for all the agronomic traits (except plant height). Among the accessions, highly significant differences (P ≤ 0.01) were found for almost all the traits excluding fifty percent flowering date, seed length, seed width. The 16 traits out of the 27 quantitative traits had a coefficient of variation (CV) ≥ 20%. A positive and intermediate to perfect highly significant association (r = 0.23 to 1.00; P < 0.00) was found between yield and its related traits. The trait dry seed weight per plant (g) had the highest GCV = 59.91% and PCV = 59.57% whereas the trait fresh pod weight (99.55%), dry seed weight (98.86%), and yield (98.10%) were highly heritable. The genetic advance recorded the highest for dry seed weight (122.01%) and lowest (3.97%) for plant height. To validate the genetic disparity, an unweighted pair-group produce with arithmetic mean (UPGMA), principal component analysis (PCA), and Hˊ-index was performed considering 27 quantitative traits. The constructed dendrogram showed five distinct groups of accessions. Genotypes G2, G3, and G9 from Group IV consider as promising lines which gave 70.05% higher mean yield compared to grand mean yield (1180 kg ha-1) with desirable traits. Group II had a maximum number of accessions while group III and group V had one of each. However, findings declared that the availability of genetic variance will be beneficial for this crop improvement and plant breeders to prefer desirable traits in V. subterranea L. Verdc. for further breeding purposes.

“…Kadar hara P daun menunjukkan pola respon linier negatif terhadap peningkatan dosis pupuk P 2 O 5 . Penelitian Lestari et al (2015) juga menunjukkan nilai kadar hara P daun dan biji yang semakin berkurang pada tanaman kacang bogor dengan penambahan dosis pupuk fosfor. Hal ini diduga karena kandungan P tersedia di dalam tanah sudah tergolong sangat tinggi sebagaimana hasil analisis tanah awal pada penelitian Lestari et al (2015), meskipun demikian kandungannya masih dalam kecukupan batas P. Selain faktor tanah, kandungan jaringan hara tanaman juga dipengaruhi oleh jenis pupuk fosfor (Winata et al, 2014) dan varietas (Singh et al, 2012).…”

Sorghum (Sorghum bicolor L. Moench) is prospective crop for food as well as feed and bioenergy. It adapts to wide agroclimate and agroecology. However, the productivity is accounted low in Indonesia. Low productivity of sorghum can be enhanced through intensification, e.g., precise dose of nitrogen and phosphorus fertilizers application. The aim of this research was to determine the optimum dose of nitrogen and phosphorus fertilizers to maximize growth and yield of sorghum in latosol soil, in order to develop fertilizer recommendation on specific soil type. The research was conducted at Cikarawang, Bogor from March to July 2015. Nitrogen and phosphorus fertilizers were arranged and applied simultaneously using randomized completely block design with three replications. Nitrogen fertilizer was applied in five levels, i.e., 0, 60, 120, 180, 240 kg N ha-1 and phosphorus levels were 0, 18, 36, 54, 72 kg P2O5 ha-1. Results showed that the application of nitrogen and phosphorus fertilizers significantly increased vegetative growth and yield components. The optimum dose were 161 kg N ha-1 (133.7%) and 43 kg P2O5 ha-1 (121.5%) for latosol soil. Keywords: fertilizer, optimum dose, soil type, vegetative, yield component
