There are many varieties of superior and local cassava (<em>Manihot esculenta </em>Crantz) in Indonesia either unknown of their photosynthesis character. The study aims to investigate the characteristics of photosynthesis and influences of physiological parameters associated the activity of photosynthesis in cassava plants. A study was conducted on Inceptisol soils at UGM research at altitude 113 m above mean sea level between January and November 2014. The treatment of single factor is cassava varieties consist of Adira-4, Malang-6, UJ-5, Singgah and Ketan arranged in a randomized block design with three replications. Cuttings size ±20 cm are planted upright with a distance of 1 m × 1 m (population of 10,000 plants ha<sup>-1</sup>). After six months, observation has been done of characters and physiological activities at 10 samples per plots and per varieties. The results showed that there are differences in the density of stomata, stomata aperture width, water content, chlorophyll content and photosynthesis rate between varieties of cassava. Singgah varieties have the Ksd highest with medium Lbs and varieties local of Ketan lowest Ksd. The group of superior varieties of cassava have Kkt medium, but varieties of Malang-6 have Kkt slightly higher and the highest rate of photosynthesis. Singgah varieties have lowest leaves Kkt and medium rate of photosynthesis. Local varieties of Ketan have the highest Kkt and lowest rate of photosynthesis. Group cassava superior varieties had higher photosynthesis rate than the local varieties, local varieties Singgah has a moderate rate and higher than Ketan. Stomata density and the concentration of CO<sub>2</sub> correlated positively and significantly affect the rate of photosynthesis while transpiration increase conductivity stomatal but negatively correlated to the rate of photosynthesis.</p>

A varietal testing had been undertaken in Pematangsiantar regency, North Sumatra province, Indonesia in 2015-2016. The objective of the study was to determine the preference of cassava growers to the introduced varieties compared to the existing cassava varieties. Twelve cassava varities (UB1/2, UB1472, Adira1, Malang4, Cecekijo, Farsem, Gajah, Ketan Jabung, Caspro, Malaysia, Adira4, and Cikaret) were tested using a Randomized Block Design with four replications. The data were taken on aboveground characters and underground characters such as root number, root diameter, root length, root weight, and starch content based on factory criteria (A = 22%, B = 18%, C = 14% and D = 10% starch content). Results of the study indicated that Malang-4 had the highest root yield (49,830 kg ha-1) followed by Farsem variety (41,690 kg ha-1), and Malaysia Local variety (41,030 kg ha-1). The bitter taste of Malang 4 was an appropriate character to be developed as starch processing of cassava. Starch content is very important indigenous criteria for farmers and traders to know fairly about pricing in relation with starch content. The higher starch content coincided with higher root yield of Malang-4 is very interesting and will benefit the factory. There was no difference in factory price of cassava from farmers, although the starch content indicated different levels (B =18%, C=14% or D =10%). The Malang-4 could be introduced to the local goverment for being grown in a larger areas in the North Sumatera province.

Astudy was carried out during 1993-1995 at the Liliana Dimitrova Horticultural Research Institute in La Habana, Cuba in order to evaluate the efficiency of cassava-bean intercropping (Manihot esculenta Crantz-Phaseolus vulgaris), and to determine the most adequate topological arrangement. The research was performed on red ferrous compacted soil. 1.4-m beds, and a randomized block design with four repetitions were used. Nine treatments were tested at three different planting times and with three different spatial distributions; control monocrops were also studied. The best topological arrangement for cassava was when it was planted at the bed center (28.3 t/ha), and beans were sowed twenty days later on both sides of the cassava. Beans also showed their best yield (1.53 t/ha) under this condition. A land use equivalent (LUE) of 1.01 – 1.85 was obtained when calculating all the combinations together.

Most of cassava grown in Palas, South Lampung District is sweet type cassava (Manihot esculenta Crantz) utilized as raw materials for cassava-based snack production. However, their characteristic had never been reported. The aims of the research were to determine the effect of varieties, harvesting age, and interaction between varieties and the harvesting age on morphology and chemical characteristics of sweet type cassava planted in Palas District, South Lampung. The experiment was factorial and arranged in a Complete Randomized Block Design (CRBD) with two factors and four replications. The first factor was cassava variety, i.e., manalagi (V1), mentega (V2), and krembi (V3). The second factor was the harvest age (U) i.e., 7-8 months (U1) and 8-9 months (U2). Morphology data were reported descriptively, while data for other characteristics were tested for homogeneity and additivity using Barlett and Tuckey test, then subjected to ANOVA, and further tested using Duncan test at the level of 5%. The results showed that the variety and harvest age significantly affected of water content, starch yield, starch content, amylose, and amylopectin. There was a significant interaction between varieties and age of harvest on moisture content, starch yield, and starch content, but there was no significant interaction effect on amylose and amylopectin. The highest value of moisture content was found in manalagi aged at 7-8 months (67.28% wb), the highest value of starch yield was found in manalagi age at 8-9 months of (16.34%), the highest value of starch content was found in mentega aged at 8-9 of months (17.52 % wb), the highest value of amylose was found in mentega aged at 8-9 of month (10.35% db), the highest value of amylopectin was found in krembi aged at 7-8 of month (92.78% db). Overall, krembi, manalagi, and mentega can be categorized as low-amylose cassava which has potential to be developed as raw material for crispy cassava-based snack.

This research was carried out at the Liliana Dimitrova Horticultural Research Institute, located in Quivicán, La Habana, Cuba. Cassava genotypes (Manihot esculenta Crantz) and common bean (Phaseolus vulgaris L.) were combined in order to determine the efficiency of these combinations for weed control. The cassava clones used were ‘Señorita’, ‘INVIT 92-1’ and ‘CMC-40’, and the bean varieties were ‘CAP-30’, ‘BAT-304’, and ‘CC 25-9 R’. Cassava was planted in 1.40 m and 0.70 m beds between plants, and beans were sowed 15 days later 35 cm away on each side of the cassava. A randomized block design was used with four repetitions. Results showed a decrease in the amount of weeds in the different intercropping combinations, as compared to weeds in monocrops. Combinations where the ‘BAT-304’ and ‘CC 25-9 R’ bean varieties were used showed greater weed control than the ‘CAP-30’ variety, thus proving the effectiveness of these systems.

The influence of NPK fertilizer on the population of two generalist pests, grasshopper (Zonocerus variegatus) and termites (Isoptera spp.) on some cassava varieties (Manihot esculenta Crantz), was investigated in a field trial carried out at Teaching and Research Farm of Department of Crop science, University of Nigeria, Nsukka. The treatments comprised all possible combinations of four rates of fertilizer application (0 kg/ha, 200 kg/ha, 400 kg/ha and 600 kg/ha), four improved cassava varieties (‘TMS 01-1368’, ‘TME 419’, ‘TMS 98-05-50’, ‘TMS 05 10’) and three modes of  fertilizer application (Single, Split and Split-split) arranged in a factorial experiment and laid out in a randomized complete block design (RCBD). There were three replications of each treatment. Data were collected on Z. variegatus and termite incidences. In each season, incidence of Z. variegatus on cassava showed significant (p<0.05) difference among varieties. Varieties ‘TMS 01-1368’, ‘TMS 05 10,’ and ‘TMS 98-05-05,’ were significantly (p<0.05) more susceptible to the pest compared to variety ‘TME 419’. Incidence of termites on cassava differed significantly (p<0.05) among varieties in the late season and variety TMS 05 10’ was more susceptible to this pest than other varieties. Rates of NPK fertilizer had significant (p<0.05) influence on Z. variegatus incidence only. Application of various NPK fertilizer rates increased the incidence of Z. variegatus on the varieties compared to plots without fertilizer (0 kg/ha). The abundance of Z. variegatus in cassava field was influenced by fertilization and variety while termites were influenced by variety.

Tuber of Cassava (Manihot esculenta Crantz) is a source of food and industrial raw materials. The purpose of this study was to examine the effect of physical treatment of cuttings on the production of cassava plants. The treatment that was tried was the physical treatment of cuttings, by being tapered, chopped, scraped, and tapered and without treatment as a control. The study used a randomized block design with four replications. The responses observed were the number and weight of tubers, and the carbohydrate content. The results showed that the physical treatment of cuttings affected the number and weight of tubers, but did not affect the carbohydrate content. The highest number of tubers and the weight of tubers is found in the tubers of the plant with tapered cuttings. The average low number and weight of tubers from plants which were treated physically on cuttings and controls compared with the physical treatment of tapered cuttings was 40.54% number tuber and 48.35% weight tuber. The average carbohydrate content is 29.62%.Keywords: Cassava, cuttings, Manihot esculenta, production

RAPD (Randomly Amplified Polymorphic DNA) is an indicator for high and stable polymorphism, widely used in the study of the diversity of cassava. In this paper, the results of using 20 polymorphic primers OPK combined with the establishment of the phylogenetic tree to analyze the genetic diversity of 26 cassava varieties with different responses to waterlogging conditions by using the RAPD-PCR technique were presented. The purpose of this experiment was to show the genetic relevance of the studied cassava varieties. The results showed that the flood tolerance of cassava was not related to the polymorphism and branching characteristics of the stem. This information may be use as a basis for selecting flood-tolerant cassava varieties for cassava production, as well as the basis for selecting genetically different parents for breeding.
