The aims of the research were to obtain informations on performance, genetic variability and heritability of some agronomic characters of M5 wheat used augmented design. Genetic meterials evaluated consist of 98 M5 putative mutant lines and six varieties as check, namely: Dewata, Selayar, Oasis, Rabe, Kasifbey, dan Basribey. The research was conducted at Research Station of BALITHI, Cipanas. Data analysis revealed highly significant for traits observed among mutant lines and check varieties evaluated. High heritability estimates were observed for plant height, tiller number, days to flowering, days to maturity, spike lenght, spikelet number, unfilled grain number, seed number per spike, seed weight per spike, and seed weight per plant. The estimated genotypic coefficient of variation (GCV) were high for unfilled grain number and seed weight per plant. Based on seed weight per plant were selected 30 best putative mutant lines. Key word: heritability, putative mutant lines, Triticum aestivum

Pohon karet pertama kali hanya tumbuh di Amerika Selatan. Perkebunan karet di Indonesia mulai diperkenalkan sejak tahun 1864, yaitu sejak Hofland mendirikan perusahaan perkebunan karet di Tanah Panunukan dan Ciasem, Jawa Barat. Serangan yang diakibatkan oleh penyakit Pestalotiopsis sp. menunjukkan bercak coklat pada daun karet dan adanya batas yang jelas antara bagian bercak dengan bagian daun yang masih sehat. Daun yang terinfeksi gugur sebelum waktunya. Umumnya yang terserang berat adalah tanaman karet yang sudah menghasilkan dan tidak terawat.

The main products are palm oil (CPO) or palm kernel oil (KPO). Both of these products have high economic value and become one of the largest foreign exchange earners compared to other plantation commodities. Until now palm oil has been cultivated in the form of oil palm plantations and processing plants to become oil and derivative products. The study was carried out in the STIPAP greenhouse. The research period was 7 months, from September to March 2018. This research used Factorial 1 design with 3x replication, the number of polybags per treatment was 3. Parameter testing was arranged on the variance list and Duncan's Multiple Range Test (DMRT) was tested at level 5 %. The results showed that the DxP Avros variety had good adaptability to water stress, especially on stem diameter, leaf number, leaf area, amount of chlorophyll, number of roots, root length, number of stomata not significantly different between treatments A1, A2 and A3.

This plant produces vegetable oils that are important for the food industry and for fuel (biodiesel). Oil palm produces the highest oil unity of area compared to other types of plants with oil potential of around 6-7 tons/ha/year. The research was carried out in the greenhouse of the Plantation Agribusiness Institute of Higher Education (STIPAP). The study period was 6 months from September to March 2018. This study also used a non-factorial randomized block design with 3 times replication, the number of polybags per treatment was 3. Parameter tests were arranged on the variance list and Duncan's Multiple Range Test (DMRT) was tested level of 5%. The results of this study indicate that DyxP DUMPY varieties have good resistance to water stress. Dy×P Dumpy varieties were relatively more adaptable and gave better growth compared to other varieties in the condition of giving 1000 ml of water which was shown in observing the height increase of plants, increasing the number of leaves, increasing the diameter of the stem.

Is a plant species that has good adaptability in various environments. As a well-adapted plant, palm oil is very tolerant of mismatches in its handling and its normal growth can recover quickly from stress due to planting movements, drought, fires and other disruptions. The saline soil is an unsuitable type of soil for the growth of oil palm crops. Utilization of humic acid as a mixed organic material for saline soil, humic acid in the soil can act as a source of nutrients, maintaining soil moisture, as a buffer by chlorizing the elements causing salinity to increase the availability of nutrients. The study was conducted in the nursery area. The study period was 5 months, from January to June 2017. This study used Factorial 2 with 3x replication, the number of polybags per treatment was 3. The parameters test were arranged on the real variance checklist, followed by continued analysis with Duncan Multiple Range Test (DMRT) with a rate of 5%. The results showed that humic acid treatment on saline soil medium with DHL level ≥4 mmhos / cm can increase plant height growth, leaf area index, root volume, root dry weight and dry weight of crown.

Chlorophyll is one of the factors that can affect palm oil production. There are several other factors that affect the productivity of oil palm plants, namely climate, territorial shape, soil conditions, planting material, and cultivation techniques. Altitude (altitude) is one of the outside factors that affect production. Differences in altitude cause differences in productivity so that production data need to be analyzed and compared. Height differences cause differences in productivity so production data need to be analyzed and compared. This research was conducted in the Bah Birung Ulu PTPN IV in April-June 2018. This study aims to determine the effect of altitude in the highlands area the effect of the amount of leaf chlorophyll on the production of oil palm fruit (Elaeis guineensis Jacq.). The method used is descriptive analytic method by processing secondary data (LM 76) and take leaf samples and measure chlorophyll content using chlorophyll meters. The results showed that in the highlands (Kebuna Bah Birung Ulu) had the highest production in 2006, amounting to 22,976 Ton / ha / year. The highest amount of chlorophyll of palm oil was found in the 2005 planting year, which was 80.5 CCI. The largest production of oil palm is in the 2006 planting year of 22,976 Ton / ha / year with 3,148 mm / year of rainfall.

This fungus can cause death, causing a decrease in the number of stands and palm oil production. One alternative to control Ganoderma boninense in palm oil is using the biological agent; ‘Trichoderma harzianum’. This research aimed to examine the inhibition of T. harzianum in various media on different spear leaves accumulations on G. boninense in palm oil plants. The research was arranged in a factorial randomized block design. The first factor was T. harzianum application with different media, the second factor was the accumulation of spear leaves on palm oil trees. The data from the observations were analyzed using the analysis of variance, followed by the DMRT at 5% level. The results of statistical tests showed that the application of T. harzianum in various media had no significant effect on the number of spear leaves at 1.5 months after application (MAA) and G. boninense mycelium at 3 MAA, but had a significant effect on the number of spear leaves at 3 MAA, G. boninense mycelium at 1.5 MAA, T. harzianum mycelium at 1.5 and 3 MAA and also significantly affected the root length at 1.5 and 3 MAA. The accumulation of spear leaves significantly affected at 1.5 and 3 MAA but had no significant effect on the observation of G.boninense mycelium, T. harzianum mycelium and the root lengths at 1.5 and 3 MAA. The interaction between T. harzianum in various media and the accumulation of spear leaves had a significant effect on decreasing the number of spear leaves at 1.5 MAA but had no significant effect on G. boninense mycelium, T. harzianum mycelium and the root lengths at 1.5 and 3 MAA. The application of T. harzianum, which was cultured in various media, was able to reduce the accumulation of spear leaves after 3 months of application. The lowest number of spear leaves was found in T. harzianum application with 25% OPEFB + 75% cow dung compost. The best of T. harzianum media in stimulating palm oil’s root growth was 50% OPEFB + 50% cow dung compost.

The first rubber tree grew only in South America. Rubber plantations in Indonesia were introduced in 1864, since Hofland established a rubber plantation company in Tanah Panunukan and Ciasem, West Java. Attacks caused by Pestalotiopsis sp. showed brown spots on rubber leaves and a clear boundary between the spots and the healthy leaves. Infected leaves fall prematurely. Generally, those that are heavily attacked are rubber plants that have produced and are not maintained. The aim of the study was to determine the resistance level of introduced clones (PB 217, PB 260, PB 330, PB 340, RRIC 100, IRR 220 and GT 1) to leaf fall disease, namely Pestalotiopsis sp. The research was conducted at the Plant Protection Laboratory of the Sungai Putih Research Institute, using a non-factorial Completely Randomized Design (CRD). The observation result showed that clones PB 217 and GT 1 had the highest attack intensity after 8 days of inocula...
