Leaf spot is a major groundnut disease in Indonesia and worldwidewhich has the potential to cause a yield loss of up to 60%. The use of leaf spot resistant cultivars is an easy, economical, and environmentally friendly way in groundnut cultivation to maintain high yields. The objective of the research was to evaluate the yields of 16 groundnut lines which had been developed to be leaf spot resistant and high yielding. The research was conducted in 2010 – 2011 at the Bogor Agricultural University (IPB) experimental station in Cikarawang, Indonesia. A randomized complete block design with three replications was used in the experiment. The groundnut lines evaluated were crosses between “Gajah”, a cultivar which is known to be susceptible to leaf spot, and the resistant line GPNC- WS4. Four Indonesian cultivars “Gajah”, “Jerapah”, “Zebra” and “Sima” were used as control. The results showed that selected lines demonstrated better resistance to leaf spot compared to “Gajah”. Their agronomic characteristics, such as pod number, filled pod number, pod weight, and kernel weight, were not significantly different from the control cultivars. The results of this study have provided information on groundnut leaf spot resistant lines for further evaluation.

Cowpea (Vigna unguiculata L. Walp) is one of the potential substitutes of soybean due to its similar nutritional content. This study aims to determine the optimum rate of N fertilizer for the production of cowpea, and to determine the effects of the interaction between N fertilizer rates and goat manure application on cowpea production. The experiment was organized in a split-plot with a complete randomized block design with three replications. The main plot was goat manure, i.e. 0 and 5 tons.ha-1; the sub-plot was nitrogen fertilizer with five rates (0, 50, 100, 150, and 200% of the recommended rate), i.e. 0, 22.5, 45, 67.5, and 90 kg N.ha-1. Application of N fertilizer reduced the 100-seed weight and slightly reduced cowpea yield and yield components. Application of goat manure increased seed dry weight per plant, number of pods per plant, dry pod weight per plant, seed dry weight per m2, productivity, 100-seed weight, and the harvest index. There was no significant interaction between goat manure and different rates of nitrogen in affecting cowpea growth.

Indeks seleksi merupakan salah satu prosedur seleksi sifat berganda yang penting dalam program pemuliaan tanaman. Tulisan ini bertujuan untuk mendeskripsi dan menduga parameter-parameter skor indeks dari metode-metode indeks seleksi nilai fenotipe, dan kemungkinan perluasannya bagi metode indeks seleksi nilai pemuliaan BLUP. Peragam fenotipe dan genotipe dari indeks basis dan Smith-Hazel digunakan sebagai landasan statistik untuk pendugaan parameter dan perluasan penggunaan indeks. Penurunan rumus menghasilkan peragam aditif dan fenotipe bagi indeks seleksi berbasis nilai eigen, dan memperoleh parameter indeks seperti heritabilitas, koefisien determinasi, respons seleksi, respons seleksi tak langsung dan respons komponen sifat-sifat kuantitatif bagi semua metode indeks nilai fenotipe. Parameter peragam nilai pemuliaan sebenarnya dapat diduga dari analisis eigen dan keakuratan nilai pemuliaan BLUP yang memungkinkan metode indeks seleksi nilai fenotipe dapat diterapkan dengan prosedur yang sama pada nilai pemuliaan BLUP. Terakhir, heritabilitas dan koefisien determinasi indeks dapat digunakan dalam simulasi pembobot ekonomis untuk menghasilkan indeks terbaik.

The quality and quantity of nutmeg fruit, seed and mace can be improved through managing fruit and seed production. Fruit development was affected by climate, flower initiation and pollination process. This study aimed to determine the correlation between climate, position, distance of pollen donor to female nutmeg trees, and the ratio of female and male trees to nutmeg yield. The study was conducted at the nutmeg germplasm collection garden at Cicurug (550 m asl), Sukabumi, tested 295 nutmeg trees from 27 locations in Indonesia. Data production of female trees was based on 2005-2017 data. All nutmeg trees were mapped using the GPS Garmin 76c5x. Tree sex was determined by male or female flowers domination in each tree. Correlation of the climate factors and production was analyzed using Pearson Correlation. The distance, position and the proportion of female to male trees were evalated by t-test at 5% level. Ratio of female and male trees to produce high yield was 4 : 1. Rainfall (280-430 mm/month) and temperature (24 - 25o C) during the pollination period (8-7 months before harvesting) were positively correlated with production by 57.9 % and 82.3 %. The position and distance of pollen donors to female trees had no effect on production. However, the distance between pollen donors and female trees above 15 m produced an average production equal to 15 m. The number of trees around tree samples had no effect on nutmeg production, but light intensity at 61,425-88,480 lux absorbed by trees could enhance the yield. Nutmeg required sunlight to penetrate plant canopy in order to induce fruit production.
