In this context, various cytokinins dosages were tested in Peru to see whether they affected the quality of caigua, in an effort to address these issues. To mitigate these problems, a pot experiment was carried out to check the effects of various doses of cytokinin in the quality of caigua in Peru. The experiment consisted of 5 treatments including (0, 50, 100, 150 and 200 mL of cytokinin) by using (Anthesis Plus per 200 L of water) as a source, each with three replicates and placed following a randomized complete block design (RCBD). Treatment with 100 mL of cytokinins foliar analysis resulted in a caigua length of 18.9 cm, an increase in diameter of 5.65 cm, and an improvement in pulp thickness of 7.60 millimeters. Physiological parameters of caigua plants taken after 45 days of sowing were considerably improved with the same treatment. Similarly, N, K and Zn concentration in leaf was higher in case of 100 mL of cytokinins foliar analysis. Therefore, policymakers must advise using the recommended quantity of cytokinins to bring about regime transition, and formers can gain by injecting 100 mL of cytokinins to boost production and the economy. It was concluded that the adequate dose of cytokinins is in treatment T3, which raised value of potassium concentration in leaves, this influenced optimal development, strengthening against environmental stress and therefore quality. For this reason, research was carried out on the comparative study of cytokinin doses in the quality of caigua in Peru; the objective was to determine the appropriate dose to obtain higher quality fruit. Likewise, it was underlined that the objective was to employ an ecological alternative of plant origin such as the usage of phytohormone that stimulates the growth of the plant and consequently the quality of the fruit. The obtained the results were served as a recommendation for farmers in the area Tue, 30 Dec 2025 00:00:00 GMT http://hdl.handle.net/20.500.14067/12916 2025-12-30T00:00:00Z http://hdl.handle.net/20.500.14067/12913 Increase in anthocyanins and their relationship with nutrition, stomatal density, and yield of purple lettuce (Lactuca sativa L.) nourished with humus based on vegetable waste Castañeda Chirre, Elvira Teofila; Cruz Nieto, Dante Daniel; Castro Bartolomé, Héctor Jorge; Nunja García, José Vicente; Chirito Laurencio, Carlos Alejandro; Lomparte Ramos, Fanny del Pilar; Cruz Nieto, Abel Eduardo; Gástulo Chávez, Mará Elena; Hijar Guzman, Raymundo Javier; Gavedia Garcia De Hijar, Gladys Margot; Aguilar Anccota, Rene; Caira Mamani, Cirilo Mario; Morales Alberto, Manuel Nicolas; Chiclla Salazar, Armando Global food security faces challenges due to the geopolitical situation, climate change, unhealthy diets, and the post-pandemic period. In Peru, the effects of the socioeconomic crisis were also felt, especially in the increase in food prices. For this reason, research was conducted on the increase of anthocyanins and their relationship with nutrition, stomatal density, and the yield of purple lettuce nourished with humus based on vegetable waste (HBVW). The objective was to determine the increase in anthocyanins in relation to nutrition, stomatal density, and the yield of purple lettuce nourished with HBVW. The methodology is based on applied research with an experimental approach; for this, a completely randomized block design was used, consisting of 3 blocks and 5 treatments, which were T1 with 0, T2 with 6, T3 with 8, T4 with 10, and T5 with 12 t ha-1 of HBVW. The doses were applied 15 days after transplanting, and physical characteristics were evaluated (total plant length, weight of purple lettuce, diameter of purple lettuce, and commercial yield), nutrient concentration in leaves (nitrogen, potassium, phosphorus, calcium, magnesium, sulfur, molybdenum, iron, manganese, copper, zinc, boron, chlorides, and sodium), anthocyanin concentration, total nitrogen, and phosphorus consumption. Also the stomatal density and profitability. Results determined that T5 stood out in total plant length with 28.90 cm, lettuce weight with 96.33 g, diameter with 17.07 cm, and commercial yield with 19.387 t ha-1 . Total nitrogen consumption with 291.44 kg ha-1 and total phosphorus pentoxide consumption with 412.98 kg ha-1 and profitability with 88.4%. Nutrient concentration in T4 leaves with sulfur, molybdenum, manganese, copper, zinc, and boron. Anthocyanin concentration T2 with 364.62 mg/100 g and stomatal density T1 with 460 stomata/mm². He concluded that the appropriate dose (T4) significantly stood out in anthocyanin concentration and yield. This dose provided nutrients to the soil that improved availability for greater absorption by the plant, which influenced higher nutrient concentration and an adequate number of stomata in the leaves. These biochemical characteristics optimized the reactions of photosynthesis, carbohydrate formation, and translocation and increased anthocyanin synthesis.
