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.

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.

<p>Productivity relates to the ability of photosynthesis. Therefore, the process of photosynthesis is important to promote growth, development and yield. 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>

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
