“…The information obtained in this study, and in the earlier research, indicates that the crops planted in November had an earlier bulking of storage roots than the crop planted in May. According to Puangbut et al [42], low temperature induced tuber development and partitioning of assimilates in Jerusalem artichoke, and the crop planted in the early rainy seasons had lower tuber dry weight For the crops planted in May 2016, photosynthesis rates in the top of the canopy were highest for both rainfed and irrigated crops at three and six MAP. The rainfed crop generally had higher photosynthesis rates than did the irrigated crop.…”

Seasonal Variations in Canopy Size and Yield of Rayong 9 Cassava Genotype under Rainfed and Irrigated Conditions

et al. 2019

The objectives of this study were to investigate the effect of seasonal variation on canopy size, and the effect of canopy size on light penetration of ‘Rayong 9′ cassava under irrigated and rainfed conditions. Rayong 9 was planted under two water regimes in a randomized complete block design with four replications in May and November for two years. At final harvest, years were significantly different (p ≤ 0.05) for biomass, shoot dry weight, and harvest index and contributed to large portions of total variations in shoot dry weight (56.8%) and HI (44.5%). Planting date was a significant source of variations in all measured characters, and it contributed to the largest portions of variations in biomass, storage root dry weight and storage root fresh weight (46.1–60.9%). Water regimes were not significantly different for most characters except for harvest index (p ≤ 0.01). The canopy of the crop planted in May grew rapidly in early growth stages in the rainy season and then slowly after the rainy season. The canopy of the crop planted in November grew rapidly in the middle to the late growth stages. Irrigation did not significantly increase root yield although it slightly increased canopy development, leaf area index (LAI), light penetration and photosynthesis. Irrigation at the late growth stages of the crop planted in May significantly increased storage root yield. Irrigation at these growth stages helped maintain canopy development, LAI and light penetration.

“…In other tuber crops such as Jerusalem artichoke, low temperatures and short photoperiods favored tuber development but reduced the vegetative and reproductive development [7,8]. These authors also reported that when the crop was grown in the post-rainy season, it had a higher tuber dry weight than did the crop grown in the early rainy season, whereas the crop grown in the early rainy season had a higher total dry matter than did the crop grown in the post-rainy season.…”

“…Multi-environment trials have been found to be essential for determining the genotype stability and predicting the performance of the traits across environments [6]. The reports in tuber crops demonstrated that effect of the season is higher magnitude than the effect of the years for biomass and tuber yield, and the genotype by season interaction was more important than genotype by year interaction [7,8], indicating the importance in the evaluation of cassava genotypes across seasons.…”

Seasonal Variation in Starch Accumulation and Starch Granule Size in Cassava Genotypes in a Tropical Savanna Climate

et al. 2018

The information on genotypic responses to the seasonal variation in the starch content, starch yield, and starch quality of cassava is limited. The objective of this research was to investigate the seasonal variation of starch characteristics of three cassava genotypes grown under irrigation. The experiment was conducted at four planting dates (20 April, 30 June, 5 October, and 15 December 2015). Three cassava genotypes (CMR38-125-77, Kasetsart 50, and Rayong 11) were evaluated in a randomized complete block design with four replications and the plants were harvested at 12 months. The planting date contributed the largest portion of the total variation in the starch content, starch yield, and starch granule size. The amylose content variability was heavily influenced by genotype. Cassava planted on 5 October or 15 December had greater starch content, starch yield, and starch granule in most genotypes. This was likely due to a higher temperature and solar radiation during the 3–9 months post-planting. CMR38-125-77 showed a consistently high starch content, starch yield, and high amylose content for most planting dates except for the starch yield on 20 April, of which Rayong 11 was the best. These findings will be useful for choosing suitable cassava genotypes for different growing seasons and for facilitating breeding efforts for high starch-yielding and high-quality cassava starch in the future.

“…Pertumbuhan umbi menurun dengan peletakan umbi pada kedalaman tanah yang lebih dalam karena memiliki berat jenis tanah yang lebih besar (Chang et al, 2016). Ketersediaan air pada ruang tumbuh umbi mempengaruhi pertumbuhan dan bobot kering umbi (Puangbut et al, 2015). Pembentukan umbi sangat sensitif terhadap kekurangan air pada ruang tumbuhnya (Daryanto et al, 2017).…”

Food diversification is one of the ways in order to achieve national food security. One of the alternative food that has the potential to be developed is tuber of Dioscorea alata (uwi, ubi kelapa, keribang, water yam). The aim of this experiment was to determine optimum water content of field capacity and spesific weight of the tuber growing space of Dioscorea alata to produce maximum growth and tuber productivity. The experiment was arranged in Randomized Complete Block Design with five replications. The treatment of this research included without planting hole, with planting hole, husk addition as much as 50% of planting hole volume, husk and manure addition as much as 50% and 25% of panting hole volume, manure addition as much as 25% of planting hole volume. The result of this experiment shows that the treatment give significant effect on the physical characteristics of the soil and vegetative growth of plants (except plant height variable), but no significant effect in increasing the productivity of tubers. For the physical characteristics of the soil, the addition of planting hole, husks and manure has the lowest value of soil density and the highest value of soil field capacity. For the vegetative growth phase, planting in planting hole and addition of husks and manure has the highest number of leaves and the number of branches.The optimum water content of field capacity and spesific weight of the tuber growing space was 39.68 % dry weight based and 0,69 g.cm-3 respectively.
