Its climbing nature and environmental resilience make it ideal for urban cultivation in pots and climbing frames. This study, conducted in a limited urban space, aimed to determine optimal pot size and cultivars for yard-long bean cultivation, emphasizing growth and yield. Two pot sizes were used: a larger one (30 cm diameter x 37 cm height, M1) and a smaller one (30 cm diameter x 30 cm height, M2), alongside three commercial cultivars: Kanton Tavi (V1), Camellia (V2), and Arafi (V3). Results indicated that a larger pot size increased pod number and total pod weight per plant, facilitating root development, vine growth, and enhanced yield. The larger substrate volume retained moisture and boosted plant biomass. Cultivar treatment affected branch length and flowering time, with Camellia exhibiting the longest harvest period (14 harvests). Hence, for Camellia varieties, cultivation using larger pots (30 cm diameter x 37 cm height) is recommended.

Thus, there is a need to curtail pesticide use and reduce the environmental impacts of pesticides. This study confirms that it should be possible to reduce pesticide use in the US by 50% without any decrease in crop yields or change in 'cosmetic standards'. The estimated increase in food costs would be only 0.6%. This increased cost, however, does not take into account the environmental and public benefits of reducing pesticide use by 50%.

Red lettuce (Lactuca sativa Var. Red rapids) is a type of leaf lettuce, this type of lettuce has leaves that are red, wide, thin, and clustered and look curly. Efforts to get maximum crop yields are by regulating plant populations so that they are efficient. This study aims to determine the effect of population and water level on the growth and yield of red lettuce. The method used in this study was a factorial randomized block design. The main factor was the population (P), which consisted of 3 treatments, namely 1 plant/pot (P1), 2 plants/pot (P2,) and 3 plants/pot (P3). The second factor was the water substrate interface (WSI), which consisted of 3 treatments, namely 1 cm (WSI1), 2 cm (WSI2), and 6 cm (WSI3). The results showed that red lettuce gave a different response to each population. (P2) produces the highest average number of plant leaves, this shows that plants with a population of 2 plants/pot are quite efficient in utilizing space so that plants grow well, characterized by a higher number and leaf area. The water interface contact area with a depth of 6 cm produces a root length value that is smaller than 1 cm and 3 cm. In a state of water saturation, roots cannot develop properly so that root growth becomes stunted.

Young fruits are harvested at a time when the seed coats have been established, but cotyledons have not yet formed. This study covered morphological characteristics, growth behavior, and cultivation practices suitable for increasing the production of the ridge gourd in urban ecosystems. Results of observation revealed the heart-shaped leaf of the ridge gourd was very uniform, and the leaf surface was flat so that their leaf area could be accurately estimated using leaf length and/or width (R2 > 0.97). Yet, leaf thickness was not a reliable predictor for the leaf area (R2 < 0.34). The length of petioles was not correlated with the leaf blade area. All single leaves, multiple tendrils, an inflorescence of male flowers and/or a single female flower, and a branch could be formed at each stem node. Water content in the leaf blade was lower than in the petiole. This phenomenon is related to water favor loss due to transpiration activity. Nevertheless, the total conserved water within the leaf blade was 6.26 times more than those within the petiole. The process of fruit enlargement followed the Sigmoid curve. The upper end of the curve started to flatten 10 days after the female flower bloomed. Moreover, at the age of 10 days, cotyledon has not yet formed, so it can be used as a guide to determine the harvest time of the gourd ridge fruit. Based on the leaf SPAD value, by the time the fruit began to enlarge, 4-5 leaves at the stem base were instigated to show symptoms of senescence. Ridge gourd fruit fresh weight can be best estimated using the length × diameter of the plants as a predictor. Keywords: Climbing vegetable, Fruit age, Leaf shape, Sigmoid curve, Urban olericulture
