Abstract

Productivity and cropping intensity on non-tidal wetland in South Sumatra are considerably low and has been underutilized up to now. The majority of farmers in this ecosystem are smallholders with limited adoption capacity on introduced technologies and modern agricultural practices. The objectives of this research were (1) to comprehensively capture multidimensional constrains that restrained local farmers in increasing their agricultural productivity; and (2) to identify, assess, and develop substantially-relevant, financially-affordable, and socially-acceptable agricultural technologies and practices for smallholder farmers to increase productivity. This research was organized in three main activities: qualitative research employing Grounded Theory procedure, quantitative questionnaire-guided survey, and a series of laboratory and field experiments. The research results indicated that the main constraints in increasing productivity and cropping intensity on the non-tidal wetland in South Sumatra include (1) unpredictable flooding occurrence and low soil nutrients content (agronomic constraint), (2) low financial and technology adoption capacity of local farmers (economic constraint), and (3) public policy has not significantly escalated farmer’s motivation to increase food production (social and institutional constraint). This research suggests that multidimensional (technical, financial, ecological, and socio-cultural) approaches should be integrated in collective efforts for sustainably intensifying food production on the non-tidal wetland.

Abstract

The use of eco-friendly methods in controlling pest and diseases has become an increasing concern in production system in many economically important crops, including ornamentals. The application of plant extract that has an insecticidal effect is considered as one promising alternative in reducing the negative effects of synthetic pesticides. The research was conducted to assess selected plant extracts in several concentrations against leaf miner (Lyriomyza spp.) in chrysanthemum. The experiment was carried out from January to December 2017 under plastic house conditions at the Indonesian Ornamental Crops Research Institute (IOCRI). The extracted organ of insecticidal plants regularly sprayed into chrysanthemum plants and compared with water as the controls. The results showed that the application of insecticidal plants extracts reduced attack intensity and incidence from water treatment (control). Certain treatment combinations, Chinese mahogany leaf extract at the concentration of 0.25%, C. pyrethrum petal 0.15 and 0.30%, and chinaberry leaf at 0.3, 0.35% even had 0.9-3.13% lesser attack incidences than commercial botanical insecticide Neem Plus. The respected treatments also supressed more than 62% leaf miner attacks and induced the increase of marketable flowers.

Abstract

Pruning is one of the techniques to improve plant growth and production. The aim of this research was to determine the effect of pruning on vegetative and generative growth, and fruit quality of ‘Crystal’ guava. The experiment was conducted from September 2016 to April 2017 at Cikabayan Research Station of Bogor Agricultural University, Dramaga, Bogor, Indonesia (-6.550780, 106.714531). The experiment used completely randomized design with six replications. There were three treatments i.e. a) pruning by leaving 4 pairs of leaves, b) pruning by leaving 8 pairs of leaves, and c) control (without pruning). Pruning was applied after shoot leaves grew fully. The result showed that pruning significantly increased the total number of shoots and generative shoots. Pruned plants produced more flower and fruit than un-pruned ones. Pruning by leaving 4 pairs of leaves tended to produce higher number of flower and fruit than those by leaving 8 pairs of leaves. Fruit weight and internal fruit quality were not affected by pruning.

Abstract

Contribution of biofertilizer in Indonesia as an alternative material for improving soil fertility and crop production is still limited. This may due to several major obstacles on its utilization and effectiveness regarding to it quality in term of its microbial viability of inoculants on formulations. This study aims to determine the effect of liquid biofertilizer formulations made from vermiwash carrier material on indigenous bacterial viability and its testing on germination of green beans ‘Vima-1’. The study included: (1) optimization of pH for the growth of inoculants bacterial consortium in vermiwash formulations with various additives, (2) viability tests and (3) pathogenicity tests of biological fertilizers on green bean sprouts (vegetative phase). The results showed that the best pH for the growth of the consortium of three bacterial isolates was at 5.5. Liquid formulation with a carrier material in the form of vermiwash plus 1% PEG (VP3 treatment) supported the highest viability of the bacterial consortium during 8 weeks incubation. All treatments did not inhibit the growth of green bean sprouts and symptom of pathogenicity was absent in all treated plants. From all treatments, the tallest green bean sprout was detected at VP3 treatment.

Abstract

The importance of patchouli plants to produce essential oil has established this medicinal herb as one of the Indonesia’s main economic contributor. To date, Indonesia can only provide 5 varieties i.e. Sidikalang, Tapak Tuan, Lhokseumawe, Patchoulina 1 and Patchoulina 2. In order to increase national patchouli production, several efforts needs to be done by providing new superior patchouli lines. This experiment was undertaken to reveal diversity of mutant progenies derived from gamma ray irradiation in patchouli. Six SSR primers were used to determine genetic diversity on MV3 generation of the mutants. Molecular analysis revealed a moderate to high polymorphism based on tested primers, which amplified 73 bands, and resulting of 0.705 PIC value. Dendrogram analysis based on Euclidean dissimilarity showed broad diversity that ranged from 0.23 to 0.82. Phenotypic tree gave clear separation that all mutant clones were clustered into three different group, with Eucledian dissimilarity coefficient ranging from 0.02 to 0.13. This report indicates that Patchouli vegetatively-propagated mutants were able to maintain their variability continuously from their parental lines (M0). Furthermore, our findings offer comprehensive information on breeding strategies of patchouli plants, giving an opportunity to assess important traits at early generation.

Abstract

The main advantages of pandan (Pandanus amaryllifolius (Roxb.) is the fresh leaves which mainly used for the pleasant fragrance in cuisine. 2-acytile-1-pyrroline (2AP) (also known as 1-(3,4-dihydro-2H-pyrrol-5yl)ethanone) is the principle volatile chemical responsible for the fragrance in pandan.  2AP was identified for the first time from the cooked rice. Many cultivars of certain crops also produce pandan-like fragrance/2AP including rice (Oryza sativa L.), sorghum (Sorghum bicolor (L.) Moench), mungbean (Vigna radiata (L.) Wilczek), soybean (Glycine max (L.) Merr.), coconut (Cocos nucifera L.), cucumber (Cucumis sativus L.), wax gourd (Benincasa hispida), and taro (Colocasia esculenta (L.) Schott). The fragrant crop varieties command higher price than non-fragrant cultivars. Breeding for fragrance is a main goal in breeding programs in these crops. Although genetics studies revealed that the presence of fragrance in crops is monogenic trait and that mutation(s) resulting in null or reduced function of betaine aldehyde dehydrogenase 2 (BADH2)/amino aldehyde dehydrogenase (AADH) causes production of 2AP, the level of the fragrance is quantitative in nature. In this paper, we review and discuss the genetic controls of the fragrance in some crops.

Abstract

Black Rice is rice producing anthocyanin in high intensity and popularly consumed as functional food. Long harvesting age and low productivity are the inhibiting factors in black rice breeding. High plant crown potentially results in plant fall-down. Mutation induction is expected to be able to improve the character of black rice. Therefore, the objectives of this research were to get more early-ripening black rice mutant, with shorter plant crown and increase productivity by inducing mutation in three varieties of local black rice using gamma-ray radiation. This experiment employed three local varieties as the first factor comprised Cempo Ireng, Cempo Melik and Melik. The second factor was the gamma-ray radiation dose, consisting of 4 levels: without radiation, radiations at 100 Gy, 200 Gy and 300 Gy doses. The results indicated that Melik variety is very potential. Melik variety has shorter plant crown with a responsive character in number of tiller for higher productivity. Moreover, radiation significantly reduces the duration of flowering and harvesting. However, to achieve a more stable character and lower flowering and harvesting period, the radiation needs to be continued in the next generation. The doses of radiation produces a response that varies in both morphological and biochemical properties.

Abstract

This study was to investigate the use of waste mushroom substrate (WMS) material, and waste mushroom substrate pellets (WMSP), with two catalysts (K2CO3 and CaO), as biofuel feed to produce CH4 in an updraft gasifier. The WMS was made from composted rubber wood chips which had been used for mushroom bed log culture, and pelletizing the WMS (WMSP) to create a biomass with a greater bulk density than the normal WMS. The gasification was determined in the high temperature range of 400-800 0C by dry fuel feeding at the rate of 25 kg/ha. The results showed that the optimum operation was achieved with WMSP with K2CO3 as the catalyst, at ER = 0.11. The combination of WMSP and K2CO3 produced more CH4 at 62.2 and 15.27% than single WMS and WMSP, respectively. WMSP with CaO as the catalyst produced 29.65 % less CH4 than WMSP. Based on gasification equation, CO produced from WMSP was calculated 24.116 % wt, 31.52% wt from WMSP with K2CO3 and 19.21% wt from WMS. The amount of gas produced from the available waste material as the biomass was sufficient to meet all heating requirements of the mushroom production.
