Abstract

The slope of land in oil palm plantation areas is the one of the primary causes of low soil water content due to low rates of soil infiltration. Biomulch is one of the conservation methods that can be used to cover and shield the soil from weeds, prevent soil erosion, and increase the rate of soil infiltration. Arachis pintoi is a perennial, stoloniferous legume crop that has potentials to be used as biomulch. The objective of the research was to study the role of Arachis pintoi in increasing the rate of soil infiltration on a sloping land of oil palm plantation. The research was conducted on the slope land (22.8%) of the Bukit Kemuning Farmer Group, Mersam, Batanghari, Jambi, Indonesia (01036'21", 102057'11") from September 2017 to March 2018. The environmental design used in this study was a one-factor randomized block design (RBD) with five ground cover treatments, i.e. natural vegetation, Arachis pintoi, Centrosema pubescens, Pueraria javanica and Calopogonium mucunoides. The results showed that the average growth rate of A. pintoi was 2.47 cm per week, which was lower than the growth of other treatments. The root length of A. pintoi was 50.36 cm at 20 weeks after planting. A. pintoi can be used as biomulch; sloping land planted with A. pintoi had an infiltration rate of  49.30 cm per hour at 20 week after planting, i.e. an increase of 32.47% compared to the infiltration rate with the natural vegetation.Keywords: land cover crop, Centrosema pubescens, Pueraria javanica, Calopogonium mucunoides

Abstract

Cowpea is prospective as a substitute for soybeans, as raw material for tempeh. In this study, low inputs of cowpea production is proposed. This study aimed to determine the effect of manure and nitrogen fertilizer on the growth and production of cowpea. The study was conducted at the Cikabayan Experimental Station, IPB, Bogor, Indonesia, from November 2018 to March 2019, using a split-plot design. As the main plot was goat manure rates consisted of 0, 2.5, and 5 tons ha-1. The subplots consisted of four rates of nitrogen, namely 0, 15, 30, and 45 kg N ha-1. The results showed that the application of manure increased the fresh weight of the leaf, the number of flower bunches, and the number of flowers. The application of N fertilizer increased leaf fresh weight, leaf area index, dry root weight, and shoot/root ratio at five weeks after planting. The combination of organic fertilizer with a dose of 2.5 tons ha-1 combined with 45 kg ha-1 nitrogen fertilizer tends to give better productivity than without fertilizer. Thus, cowpea can be produced using low input of manure and N. Keywords: leaf area index, leaf weight, flower bunches

Abstract

Agroforestry-based coffee is one of the conservation efforts to restore the damages at the Citarum watershed. Planting annual crops between coffee rows could potentially contribute income for the growers during the immature non-productive coffee growth. The aims of the research is to study the effect of various types of agroforestry models in the upstream Citarum watershed on the growth of coffee, and growth and yields of the intercrops. The research was conducted in September 2018 to June 2019 at the upstream Citarum watershed of Tarumajaya Subdistrict Kertasari, Bandung Regency, West Java, Indonesia. The research was arranged with a randomized block design with two factors. The first factor was the cropping system, i.e. coffee monoculture, coffee and corn, coffee and sweet corn, coffee and red beans, and coffee and habanero chili. The second factor was organic matter application, i.e. with and without application of in situ organic matter. The results of the research showed that coffee intercropped with habanero with application of in situ organic matter had the best vegetative growth, indicated by taller plants, more leaves, increased leaf P and Mg levels, and the maximum income from the intercrop. Coffee intercropped with corn with application of in situ organic matter had a maximum corn production but had the lowest income. Therefore, the model of coffee intercropped with habanero chili with application of in situ organic matter was the best model from several intercropping systems tested.

Abstract

Natural populations of sago (Metroxylon sagu) in Indonesia show morphological variations in its organs, particularly the leaves. The existing variations resulted in sago type names provided by the locals. The sago plant types include Mahang, Buntal, Salak, Madang and Gandut. Sago leaves are economically important in Indonesia, mainly because they provide a potentially profitable and environment-friendly source of house roofing materials. Determining leaf variation among sago plants would provide information for a better way of choosing which among the current accessions/varieties of sago has the best leaf quality and production. Leaf variations in sago were recorded in shape, size, and color. The aim of this study are a) to compare differences in leaf morphology among sago types obtained from different geographic areas, and b) to determine whether these different sago types correspond to certain sago plant grouping. The qualitative and quantitative analysis showed variations in leaf characteristics of sago trees. Additionally, this study shows that based on leaf variations, the sago of South Borneo Province can be separated into two groups. The first group is Mahang and Gandut, which have long rachis, leaflets and leaves, and largest leaf area. The second group composed of Buntal, Salak and Madang accessions, which have short rachis and leaves, and smallest leaf area. Other results showed that there were characters that contributed significantly to the diversity of sago plants in the study area including spines, white stripe or banding on the rachis and petiole length. In line with our results, Mahang and Gandut accessions are the best accessions to be cultivated in the area, because they have wider leaves which support higher rates of photosynthesis. Further study should be conducted on phylogenetic using DNA sequencing to confirm divisions of the two sago groups.

Abstract

Applying and optimizing an intercropping system between oil palm and seasonal crops such as maize in the immature palm oil plantation is one way of obtaining additional income for farmers until the main crop (oil palm) mature and ready to harvest. The aim of the research was to determine the effects of fertilizers, particularly nitrogen (N) and potassium (K) on the growth and production of maize in an intercropping system with oil palm. The experiment, using one-factor randomized complete block design, was conducted at the Cikabayan Experimental Station, IPB University, Indonesia, from August to December 2020. Four set-ups were prepared corresponding to four different fertilizer applications as follows: A0 (without treatment), A1 (240 g Urea + 80 g KCl + 320 g SP-36 per plot), A2 (480 g Urea + 160 g KCl + 320 g SP-36 per plot), A3 (720 g Urea + 240 g KCl + 320 g SP-36 per plot). Applying the highest dosages of N and K (A3), significantly increased plant height, fresh weight, number of leaves, leaf area, stem diameter, cob length, cob weight, and husk-free cob weight. Intercropping maize with immature oil palm did not affect the oil palm growth.

Abstract

Sago is a carbohydrate-producing palm witharea about 382.198 ha in Mimika Regency. So far, research on the characterization of sago palm in this area has not existed, therefore it is necessary to do. The diversity of sago accessions in Mimika District is expected to be a source of germplasm and superior sago selection to support sago development. This study aims to obtain information about morphological characters and starch production of some sago accessions. The study was conducted using observation method of seven sago accessions, namely Mbupuri, Monepikiri, Mbapare, Tuwae, Aute, Iyaremeta and Bakaketemeta in Iwaka District, Mimika Regency, Papua Province. The result showed that the seven accessions sago differed based on morphological character namely stem, leaves and spine, and starch production. The Monepikiri accession has the longest stem and large stem diametre, namely 13.75 m and 59.00 cm, respectively. Accession Mbupuri has more leaves and wider leaves than the others. Accession Monepikiri has a production potential of more than 300 kg’s dried starch/palm and accession Mbupuri more than 200 kg’s dried starch/palm. Both accessions of this sago can be further investigated the stability of yield starch to be released as superior varieties. The morphological characters, especially the length of the stem affect the starch production because the starch is present in the pith of the stem.ABSTRAKSagu merupakan tanaman sumber karbohidrat dengan luas areal di Kabupaten Mimika 382.198 ha.

Abstract

Papua, Indonesia is the largest sago palm (Metroxylon spp) distribution area in the world. Most (85%) of the total sago area in the world is in Indonesia, and 95% of the sago area in Indonesia is in Papua and West Papua. Field observation of accessions of sago palm was conducted at the sago growing area at Hiripau village. The aim of the study was to determine the diversity of sago palm accessions from Hiripau village and compare their morphology and starch production. Based on interviews with the local farmers, the four accessions of sago palm that dominated the Hiripau area are Nakowai, Mapartaro, Tuhai, and Korearipi. These accessions vary in the spine characteristics, features of the trunk, leaf, pith, and starch production. Sago Mapartaro leaves are the largest (23.56 m2) and the leaflet areas are almost twice the size of the other accessions. Tuhai has the highest starch yield but it has high ash content resulting in low starch quality.

Abstract

The purpose of this field verification was to determine the stability of yield of several drought-tolerant soybean genotypes selected from green house evaluation. The plants were planted at Muneng, Probolinggo in dry season (June-September 1995) with and without irrigation. From 5 tolerant genotypes, Mlg 2999 and Mlg 3474 gave a good stability of tolerance as evidence by less significance of growth and grain yield reduction. The tolerant genotypes of Mlg 2805 and Mlg 2984 suffered from tremendous leaves and pods abcission, leading to low yield.
