Clitoria ternatea L. is a plant species that can be used in food and pharmaceutical industry. This study was conducted to evaluate the effects of different plant spacing on the productivity and quality of butterfly pea grown on grey soil in Thu Duc, Ho Chi Minh City. Six treatments correspond to plant spacing of 80 x 15 cm, 80 x 20 cm, 80 x 25 cm, 80 x 30 cm, 80 x 35 cm and 80 x 40 cm. The results showed that the highest flower amount (296.8 flowers/plant) was obtained with butterfly pea planted at the spacing of 80 x 15 cm, commercial flower weight (7.86 g/100 flowers), theoretical yield of fresh flower (1,779.0 kg/1,000 m2, actual yield of fresh flower (841.9 kg/1,000 m2), theoretical yield of commercial flower (194.6 kg/1,000 m2 and actual yield of commercial flower (89.0 kg/1,000 m2. Nevertheless, plant spacings did not affect the dry matter ratio, anthocyanin and tannin content in the commercial butterfly flowers

Pollen Quantity

Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants (0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen resulted in higher seed yield per area, but the plant spacing did not affect this characteristic. Manual pollination, using a whole anther, did not differ from natural pollination in relation to seed yield and quality.

A study was carried out to evaluate the effect of head decapitation and planting density on plant growth, seed yield and quality of sprouting broccoli, Brassica oleracea var. italica L. using cultivar ‘Green Head’. The twenty treatments comprised of combinations of four head decapitation methods viz., D1 (decapitation of primary head at appearance and harvesting seeds from secondary heads), D2 (decapitation of primary head at marketable stage and harvesting seeds from secondary heads), D3 (removal of secondary heads at appearance and harvesting seeds primary head) and ‘D4’ (No decapitation- control) and five planting densities viz., S1 (60x60 cm), S2 (60x45 cm), S3(45x45 cm), S4 (60x30 cm), and S5 (45x30 cm). Decapitation of primary head at appearance and harvesting seeds from secondary heads (D1) and planting density S3 (45x45 cm) independently as well as in combination gave highest seed yield per plot and per hectare. This combination was also found comparable to other combinations for other characters like days to 50% flowering, days to seed harvesting, plant height at harvesting (cm), number of branches per plant, number of siliqua per plant, siliqua length (cm), number of seeds per siliqua and seed quality parameters. Therefore, it is suggested that decapitation of primary head at appearance and harvesting seeds from secondary heads (D1) in combination with plant spacing of 45x45 cm i.e. D1S3 can be recommended for commercial seed production of sprouting broccoli.

<p>Genetic diversity among the butterfly pea genotypes is important information to support breeding program of this underutilized crop. The important characters to be targeted in the breeding program of this crop included yield and yield components of flowers that are strongly affected by the environment and have not been previously reported. This study aimed to determine the genetic diversity of butterfly pea (Clitoria ternatea L.) from Indonesia tested in two land conditions, namely dryland and former paddy fields, based on flower character and yield component traits. The results showed that butterfly pea accessions were divided into two main clusters with dissimilarity coefficient of 0.01–3.99 indicating wide genetic diversity across  accessions. The Mantel correlation showed that the genetic distance among accessions studied were not significantly correlated (r = 0.044, P = 0.8709). Based on principal component analysis (PCA), the eigenvalue ranged from 1.69 to 3.34 with a cumulative contribution of 72.64%. The traits that influenced genetic diversity in this study were flower length, weight of one fresh flower, total weight of pods, and weight of 100 seeds. The results of this study should be useful to support future butterfly pea breeding program.</p>
