Abstract

ABSTRACTSago palm is a carbohydrate source which has the highest carbohydrate content compared to the other crops. It can produce about 200-400 kg per trunk of sago dry starch. More than 50% sago palm population in the world are grown in Indonesia and 90% sago palm in Indonesia is found in Papua. This research was aimed to characterize several sago palm accessions in South Sorong District, West Papua. There were 12 accessions observed, i.e. Fasai, Fasampe, Falia, Fanomik, Fasongka, Fafion, Fakattao, Fanke, Fablen, Failik, Fakreit and Fasinan. Among these accessions, there were many differences based on morphological characteristics such as shoots color, crown shape, trunk height, number of leaf, existence of spine, starch content, also pith and starch color. Fablen was the only non-spiny type. Most of sago accessions were high yielding accessions with the potential yield more than 200 kg per trunk of sago dry starch. Fanomik had the highest potential yield. Sago palm productivity in the natural forest of Saifi Subdistrict, South Sorong District, West Papua was estimated to reach approximately 34.59 ton ha-1 per year of sago dry starch.   Keywords: accessions, starch, yield, food

Abstract

ABSTRACTCover crops is widely used as biomulch because of its advantages for land conservation, weed control and increasing soil nutrients, especially in upland agriculture. The objective of the research was to study the growth and development of Arachis pintoi as biomulch in upland agriculture. The experiment was carried out at IPB Experimental Field from February until May 2014. Observation was done everyweek up to 12 weeks with 10 plants were used for each observation. One stolon of A. pintoi with 4 internodes was planted in each 0.25 m2 plot. The results showed that root initiation of A. pintoi was occured at 3 weeks after planting (wap) and produced 42.4 roots with average root length of 17.10 cm on 12 wap.A. pintoi had nett assimilation rate of 0.0023 g cm-2 per day and relative growth rate of 0.052 g per day. With this growth rate, A. pintoi covered 58% of 0.25 m2 plot and produced biomass 10.08 g per plant within 12 wap. A. pintoi produced flowers on 4 wap and pods on 7 wap. A. pintoi produced root nodules through mutualism symbiosis with local Rhizobium. The equation for rate of coverage is Coverage (%) = 5.273 Time (wap)-16.512; 100% land coverage can be reached on 22 wap. Based on the results of this study, A. pintoi is potential to be used as biomulch; however, a denser spacing must be applied for faster land coverage.Keywords: land coverage, mulch, Rhizobium, stolon

Abstract

ABSTRACTMucuna bracteata DC. is a legume cover crop to prevent erosion and to suppress weed growth. M. bracteata can fix N2 from the air with the help of Rhizobium. M. bracteata get benefit from the symbiosis in the form of increased nodule weight, shoot dry weight, and leaf nitrogen content when the Rhizobium population in the soil is optimal. Application of inoculant is one method to increase the Rhizobium population in the soil. This study aimed to analyze the effects of inoculation times and inoculant rates on M. bracteata growth. The research was conducted in Boyolali, Central Jawa, from February to August 2014. The inoculant contained Bradyrhizobium japonicum and Aeromonas punctata. This experiment was arranged in a randomized block design with two factors and three replications. The first factor was two inoculation times, i.e at the nursery when the seedlings were 2 weeks old and in the field when the seedlings reached 5 weeks old. The second factor was 5 inoculant rates (0, 2, 4, 6, and 8 g per plant). The results showed that inoculation on 5-week-old seedlings was the best result compared to the 2-week-old seedlings. The recommended inoculant rate for Mucuna bracteata was 6.43 g per plant. Keywords: legume cover crop, nitrogenase activity, nodule, nutrient content, runner

Abstract

Production of maize hybrid seed is hindered by relatively poor production by the male line pollen; short live of the pollen which was ascribed to desiccation and dehydration sensitive and flowering asynchrony between male and female lines. The aims of this study were to enhance production and viability of male line pollen and also to determine the suitable storage condition for maintaining pollen viability in order to be used for production of hybrid seed. The research consisted of two experiments. The first experiment was arranged in split plot randomized block design with NPK dosages as main plot (0, 300, 600, 900 kg ha-1) and application of boron as sub-plot (0, 1.5, 3, 4.5, 6 kg ha-1), replicated three times. The second experiment used randomized block design with two factors, i.e. storage temperature (-196 oC and -20 oC) and storage period (0, 1, 2, 3, 4 weeks). The result showed that NPK 900 kg ha-1 increased the number of spike per tassel from 9.3 to 10.7. Application of NPK 600 kg ha-1 or boron 1.5 kg ha-1 improved pollen viability. Combination of NPK 900 kg ha-1 and boron 6 kg ha-1 resulted in the highest pollen viability of 95.3%. Pollen after being stored for four weeks either in -196 ºC or -20 ºC was possible to be used for seed production with 20% seed set.Keywords: boron, freezer, liquid nitrogen, NPK dosage, pollen viability

Abstract

Melon breeding for fruit quality improvement is important to produce new varieties that meet consumers’ demand. The aim of this study was to elucidate the fruit characteristics of melon at five different maturity stages, involving several genotypes belonging to two cultivar groups: reticulatus and inodorus. The experiments were conducted in three planting seasons: (1) January-March 2015 (13 genotypes), (2) December 2015-February 2016 (56 genotypes), (3) February-May 2016 (9 genotypes). These trials were conducted at the Tajur II experimental station of IPB, Bogor, and each trial was arranged in a single factor randomized complete block design with three blocks. Maturity stages was determined based on fruit rind color and net coverage, and their effects on fruit quality were studied using combined analyses over seasons. Maturity stage significantly affected the fruit length, fruit diameter, flesh thickness, fruit weight, and sugar content. The average weight of the fruits at maturity stage 4 (838.90 g) and 5 (931.79 g) was significantly greater than that of stage 1 (584.42 g). The sugar content increased from maturity stage 2 (5.51 oBrix) to 3 (6.13 oBrix) and to 5 (8.18 oBrix). Fruit weight significantly correlated with fruit length (r = 0.53), fruit diameter (r = 0.85), fruit rind thickness (r = 0.33), and flesh thickness (r = 0.63). Maturity stages affected the quality of melon fruits, and therefore the determination of appropriate harvesting criteria is important in melon cultivations.Keywords: cantalupensis, correlation, inodorus, fruit quality, skin colour

Abstract

Purple nutsedge (Cyperus rotundus L.) is one of the important weeds in the world because of its ability to suppress the production of crops and difficult to control. C. rotundus residues can suppress the growth of others weeds. The experiments were conducted to identify the phenolic compound of C. rotundus from six different accessions and to determine the allelopathic effects of C. rotundus extracts on germination of Borreria alata (Aubl.) DC. The identification of phenolic compound was done using extract from all part of mature C. rotundus taken from different accessions and was analyzed using GC-MS. Analysis of C. rotundus extracts on germination of B. alata was designed using completely randomized design with three replications. The treatments were extract of C. rotundus from different accessions (from Cikarawang-Darmaga, Babakan-Darmaga, Ciawi, Megamendung, Cisarua, and Cianjur) with different concentration, 0.75 kg L-1 and 1.5 kg   L-1. The result showed that C. rotundus from six accession had phenolic compond with different amounts. Cianjur accesion contained the most phenol content such as 2-furanmethanol; 1,4-benzenediol; 2-methoxy-4-vinylphenol; phenol, 2,6-dimethoxy; syringic acid; and 3-hydroxybenzoic acid. Germination test showed that C. rotundus extracts from different accessions and concentration had the same inhibitory effect on germination of B. alata.Keywords: Allelopathy, bioherbicide, purple nutsedge, weed management

Abstract

ABSTRACTXanthomonas oryzae pv. oryzae (Xoo), is a seedborne pathogen causing bacterial leaf blight (BLB) disease, and reduces the quality of seed and rice production. One of the efforts to control the BLB disease and to improve the quality Xoo infected seeds is the seed coating technique enriched with biological agents. The experiment was aimed to study the effect of coating on seed quality and storage life, as well as the Xoo and biological agents resistence (P. diminuta A6 and B. subtilis 5/B) on the seeds. The experiment was carried out from August 2011 to March 2012, using a split plot design with four replications. The main plot was storage period, i.e. 0, 1, 2, 3, 4, 5, 6, and 7 months. The sub plot was seed coating treatment consisted of negative control (healthy seed); positive control (seeds contaminated with Xoo); seed infested with biological agens;  alginate 3% + 1% peat + biological agents; arabic gum 3% + 1% gypsum + biological agents; CMC 1.5% + 1% talc + biological  agents;  and  bactericide  streptomycin  sulfat 20%. The  coated  seeds were  stored an air-conditioned room (18-20 °C,  RH  48-50%). The results showed that the treatments were able to maintain seeds quality during storage, i.e. germination percentage, uniformity percentage, and vigor index, better than those of the positive control. The P. diminuta A6 was still presence (0.08 x 106 cfu mL-1) in seeds coated after 7 month storage, and the B. subtilis 5/B was still presence (0.07 x 106 cfu mL-1) up to 6 month storage with 3% arabic gum + 1% gypsum + biological agents.  Keywords: Bacillus subtilis 5/B, Pseudomonas diminuta A6, seed quality, storage space, Xanthomonas oryzae pv. oryzae

Abstract

ABSTRACTCurcuma aeruginosa Roxb., popularly known as “temu ireng”, is considered as a potential source of medicinal plant for pharmacological activities. However, varieties of C. aeruginosa are still limited in Indonesia so it needs more accessions for improvement and development of new varieties. Rhizome colors, phytochemical contents and extract yield from 20 promising lines of C. aeruginosa were investigated by qualitative method for rhizome colors and phytochemical contents, and maceration method using 70% ethanol for yield extract. Similarity analysis was used for cluster analysis based on rhizome colors, phytochemical contents and yield extract. Blue was the color characterization of rhizome C. aeruginosa. The extract yield for 20 promising lines of C. aeruginosa varied from 7.92 to 19.71%, with KN and BH promising lines having the lowest and highest value, respectively. All promising lines of C. aeruginosa contain saponin and triterpenoid. Based on similarity analysis, all promising lines could be divided into 3 clusters. Cluster I consisted of 14 promising lines i.e. WG, SH, KA, GD, BH, KP, NW, PW, MB, PR, PT, KN, MD, and PK. Cluster II consisted of 4 promising lines i.e. LC, CB, KL, and GK. Cluster III consisted of 2 promising lines i.e. KD and SG. Keywords: promising lines, saponin, triterpenoid
