“…Better seed productivity of JO S2 than the locally available variety is clear and significant. Our best second yield of 1.72 kg per plant (4.25 t ha ) set a record in India, better than all reported for wild Jatropha accessions [6][7][8][9][10]. We attribute this higher productivity mostly to improvement of genetics.…”

“…A progeny trial of 32 plus trees collected from Andhra Pradesh, India found significant differences in plant height, seed productivity, seed morphology and oil content among the 34 month old progenies with seed productivity ranged from 34 to 263 g plant −1 at spacing of 3 m × 3 m [9]. Recently, a seven site, multiple factor (spacing, pruning and irrigation and fertilizer) field trial [10] of an elite Jatropha accession in India was reported. The best seed productivity achieved was 1,440 kg ha −1 (at spacing of 2 m × 2 m) for five year old plants.…”

A New Jatropha curcas Variety (JO S2) with Improved Seed Productivity

et al. 2014

Abstract:One key reason for the failure of Jatropha plantation is the use of non-improved planting materials. We present in this paper a Jatropha variety (JO S2) through selective breeding with much better seed productivity than wild accessions as proven by field trials in Singapore and India. In a single farm trial in Singapore for two years, a comparison was conducted with accessions from China, India, Indonesia and Africa. It was found that all traits studied like seed yield, seed kernel content, seed oil content, fatty acid composition, phosphorus content and PE content differed significantly among and within the wild accessions. Overall, JO S2 was the best performer with the highest seed yield, high oil content and low phosphorus content. On two sites in Tamil Nadu, Southern India, this Jatropha variety produced up to 2.95 ton/ha of dry seeds in the first year and up to 4.25 ton/ha of dry seeds in the second year, much better than the local variety control. We attribute its higher seed productivity to early flowering, better self-branching, more flower/fruiting bunches, more fruits per bunch and importantly, better uniformity among plants. This exemplifies that breeding has improved Jatropha seed productivity which will lead to better economics for Jatropha plantation.

“…The inflorescence of J. curcas is a raceme (Kaur et al, 2011 Mat et al, 2015). The male to female flower ratio is an important factor because it is significantly correlated to yield (Wijaya et al, 2009 Singh et al, 2013). Although J. curcas is considered tolerant to drought, several studies (Kaur et al, 2011;Ma et al, 2016) showed that water has a significant effect on its phenology and particularly fruiting.…”

Jatropha curcas is the priority species for biofuel promotion in Senegal. However the lack of knowledge on floral biology and fruiting of this plant remains a problem to increase its yield and improve farmers' adoption. The objectives of this study were to assess seasonal changes on flowering and fruiting of six accessions of J curcas in semi-arid area in Senegal. In this study the total number of inflorescences, flowers and fruits were evaluated during six months on four years old plants, installed in the Agricultural Engineering School of Thies. The results showed significant effect of factors (season, accession) and interaction between them on floral and fruiting traits of J. curcas. Due to more favorable climatic conditions, the performance of flowering is better in wet season. During this season, the number of male and female flowers ranged, respectively from 107.47-191.60 and from 2.47-11.87 per inflorescence. Consequently, ripe fruits production was higher in wet season and varied between 66 and 97% of the total production. Two peaks of flowering were observed; the first one occurred in dry season and the second, with the highest number of inflorescences, arrived in wet season.

“…As for the germination of Jatropha seeds, tracing an analogy with papaya, a species that belongs to the same family as Jatropha (Euphorbiaceae) and has seeds with high oil content and whose center of origin is a tropical region, it has been recommended that the temperature for the germination of seeds is between 20 and 30°C (Singh et al, 2013). This temperature range is also recommended for the germination of most tropical and subtropical tree species cultivated in Brazil.…”

<b>Agroclimatic zoning for jatropha crop (<i>Jatropha curcas</i> L.) in the State of Goiás

ABSTRACT. Jatropha stands out in the Brazilian agribusiness scenario as one of the most promising nuts for biodiesel production, although there are few studies on this culture's introduction, management and cultivation techniques. Through the characterization of the state of Goiás' climate based on climate, rainfall and evapotranspiration maps, this work aimed to define areas suitable for the cultivation of Jatropha by designing an agroclimatic zoning system. Rainfall climatic data from 114 stations and air temperature data related to 34 stations were used. The zoning did not show any area that was considered unsuitable for the cultivation of Jatropha in the state, with much of the territory having full culture capability and some marginal regions characterized by water deficit or thermal deficiency. Throughout the state of Goiás, 64.6% of its territory is fit for the cultivation of Jatropha, whereas 35.4% has some marginal conditions for culture development. Of the total of areas defined as marginal to the cultivation of pinion, 28.8% are considered marginal due to water deficits and 6.6% are considered marginal due to thermal deficiency.Keywords: agrometeorology, climate modeling, agricultural potential.Zoneamento agroclimático para a cultura do pinhão manso (Jatropha curcas L.) no Estado de Goiás RESUMO. O pinhão manso destaca-se no cenário do agronegócio brasileiro como uma das mais promissoras para a produção de biodiesel, muito embora sejam poucos os estudos voltados para a implantação, manejo e técnicas de cultivo dessa cultura. Por meio da caracterização do clima do estado de Goiás através da geração de mapas de temperatura, precipitação e evapotranspiração, objetivou-se neste trabalho, definir áreas aptas no estado para o cultivo do pinhão manso por meio de realização de um zoneamento agroclimático. Para isso foram utilizados dados climáticos de precipitação pluviométrica de 114 estações e dados climáticos de temperatura do ar referentes à 34 estações. O zoneamento não evidenciou nenhuma área que seja considerada inapta ao cultivo do pinhão no estado, estando grande parte do território sujeito à aptidão plena da cultura, com algumas regiões marginais, ora por deficiência hídrica, ora por deficiência térmica. Do total do estado de Goiás, 64,6% do território goiano é apto ao cultivo do pinhão manso, enquanto que 35,4% apresenta alguma condição de marginalidade para o desenvolvimento da cultura. Deste total de áreas definidas como marginais ao cultivo do pinhão, 28,8% é tida como marginal por deficiência hídrica, e 6,6% é tida como marginal por deficiência térmica.Palavras-chave: agrometeorologia, modelagem climática, aptidão agrícola.
