Abstract

A number of promising sweet potato clones from East Nusa Tenggara and a checked cultivar were evaluated in several locations for the following objectives:  1) to elucidate genotype by environment effect on growth and yield of the sweet potato clones, and 2) to determine growth and yield stability of the clones across diverse locations in East Nusa Tenggara province. The study was carried out in four locations and was laid out in a Randomized Block Design consisting of 10 sweet potato genotypes as treatments and two replicates. Obtained data were subjected to combined analysis of variance to determine GxE interaction, followed by stability analysis based on joint regression model of Eberhart and Russell. Research results revealed that genotypes, locations and genotype by location interaction posed significant effect on the observed variables. Most of the evaluated clones were unstable for vegetative growth characters but were stable for tuber yield and yield components. The local clone LB-01 produced the highest mean tuber yield over all locations, averaging at 4.15 kg.plant-1 (~ 46.11 t.ha-1).  Two local clones, i.e. ON-06 and LB-01, and the check cultivar Kidal were the most stable clones for tuber yield and yield components across diverse environments.     Keywords: growth, yield, stability, sweet potato, location

Abstract

Groundnut is the most important pulse crop in East Nusa Tenggara (ENT); however, the crop yield in ENT is low due to erratic climatic condition, drought stress, and low yielding ability of most cultivated genotypes. Local Rote is a well-known local groundnut variety in ENT, which is a potential superior variety and parental source due its large seed size and high yielding ability. Information on its resistance to abiotic and biotic stresses is important for its future development. Five groundnut genotypes, Local Rote and check varieties were elucidated to identify drought resistant genotypes. The study was carried out in a split-plot design with three replicates in two locations during dry season 2013. Two irrigation regimes (optimum and stress conditions) were assigned as main plot and 5 groundnut geno-types as sub-plot. Research results revealed significant effect of irrigation by genotype interaction on observed yield and yield compo-nent characters in both locations. Seed yields of most tested genotypes were below their yield potential. Local Rote yielded best over two locations (1.26 t.ha-1 seed yield). Yields of check varieties were below 1.0 t.ha-1. Local Rote was considered tolerant to drought based on STI, GMP, SSI and YL selection indices.Keywords: groundnut, local, variety, drought, tolerance

Abstract

Local Ecological Knowledge (LEK) regarding local food plants is knowledge that is owned by local communities and is passed down from generation to generation. LED is obtained through a long process of adaptation and is used by local communities to address environmental problems. The Kabola ethnic group also has LEK regarding food plants used to solve food problems on dry land, but the LEK owned by the Kabola ethnic community is in danger of being lost. The method used is a mixed method (Mixed Methodology), which combines qualitative methods and quantitative methods, data collection begins with an exploration using a qualitative case study method by means of in-depth interviews followed by a quantitative survey method of the plant species mentioned during the interview. The results showed that the Kabola ethnic group still collects wild food plants from forests, former gardens and riverbanks, even though they have cultivated various types of food crops; The Kabola ethnic group community collects food plants during the rainy season and dry season, but most food gathering activities are carried out at the end of the rainy season and during the dry season; The people of the Kabola ethnic group collect food by using simple tools while leaving certain parts of the plant from which the food is collected; The people of the Kabola ethnic group still pass on local knowledge about foodstuffs to the younger generation through stories, personal experiences and providing examples or direct practices about plants that can be used to meet food needs; The Kabola ethnic group cultivates local food plants, but these cultivation efforts are only carried out individually and have not received support from the local government.

Abstract

A laboratory experiment was carried out to evaluate the potential sweetpotato clones from NTT for the following objectives: 1) to determine resistance level of the clones to sweetpotato weevil (SPW), 2) to investitage the effect of genotype by tuber production site interaction on SPW-resistance level, 3) to identify SPW-resistant clones. Sweetpotato roots employed in the experiment were obtained from two production sites in the fields. The experiment was laid out in a Completely Randomized Design with a factorial treatment of two factors: sweetpotato genotype (10 clones) and root production sites (two sites). Experimental unit was replicated three times. Variables observed included percentage of SPW-injured root, severity of root injury, number of larva, pupae and imago, and root morphological characters. Quantitative data were subjected to analysis of variance while qualititave data were descriptively analyzed. Results of the study revealed significant interaction effect of genotype by tuber production site on severity of root injury and number of larva+pupae+imago. NBN-01 and NPL-02 produced the lowest (4.50%) and the greatest (67.03%) severity of root injury. NBN-01 was classified “resistant” and NPL-02 was “susceptible” while the remaining eight clones/check varieties were “moderately resistant” to SPW.
