“…These results are similar to those reported by Rojas-García et al (2021), who evaluated the correlation between forage yield and meadow height in white clover with orchard grass Means with the same lower-case letter in the same column ( abcd ) and capital letters ( ABCD ) in the same column are not statistically different (Tukey: 0.05).…”

Objetive: To evaluate the growth rate, leaf:stem ratio and height of crotalaria plants (Crotalaria juncea L.), cultivated at different densities, in the dry tropics of the state of Guerrero, Mexico. Desing / Methodology / Approach: The treatments were: four planting densities at 400,000, 200,000, 100,000 plants ha-1 and trickling. A growth analysis was also evaluated at 30, 38, 45, 52, 60, 68 and 75 days of growth, including that the pod was fully developed. The variables evaluated were: growth rate, leaf:stem ratio and plant height. Results: The best growth rate was found at a density of 400,000 plants ha-1, at 75 days of development, with 577 kg DM ha-1 d-1; similar to plant height, which at this density presented 281 cm. Contrary to the leaf:stem ratio, which was greater than 30 days. Regardless of age, a descending behavior was found in the following order: 100,000 ˃ chorrillo ˃ 200,000 ˃ 400,000 plants ha-1 with 0.65, 0.60, 0.59 and 0.55 (p < 0.05). Study Limitations / Implications: This study is essential for future research because these variables have not been evaluated in this crop; being important for forage production. Findings / Conclusions: It is recommended to sow at a density of 400,000 plants ha-1, finding a higher leaf:stem ratio at 30 days of development and a plant height at day 75, when pod production also begins

Objective: To evaluate the dry matter distribution of banderita grass [Bouteloua curtipendula (Michx.) Torr.] in different plant strata. Design/Methodology/Approach: A randomized block experimental design with five repetitions was used for the experiment. Each repetition consisted of three plants which were evaluated at different days after sowing (DAS), in three different plant strata: basal stratum (BS), middle stratum (MS), and upper or apical stratum (AS). The following variables were evaluated: dry matter yield (DMY), morphological composition (MC), leaf area (LA), plant height (PH), leaf:stem ratio (L:SR), and aerial part:root ratio (Ap:rR). An analysis of variance was performed, using the PROC GLM procedure of the SAS software; in addition, a comparison of means was carried out using Tukey’s test (α<0.05). Results: SB made a greater contribution to DMY at 50 DAS, with a 16 g DMY plant-1 average, followed by MS, with 9 g DM plant-1, and AS with 3 g plant-1. The MC (g) in the BS registered that the stem made a greater contribution than the rest of the components (average: 12.3 g plant-1), while leaves from the MS and AS made the greatest contribution (2.6 g plant-1) up to 64 DAS. However, they were surpassed by the stem in the MS and by the inflorescence in the AS. In addition, BS registered the highest LA (173.4 cm2). The largest PH was recorded at 120 DAS (96 cm). The highest L:SR ratio reached 1.10 at 50 DAS, while Ap:rR recorded 3.82 at 92 DAS. Study Limitations/Implications: The experiment was carried out under greenhouse conditions. Therefore, any extrapolation or comparison with field conditions should be done with caution. Findings/Conclusions: The basal and middle part of a banderita grass (Bouteloua curtipendula) plant contains the highest forage accumulation (mainly in the leaves and the stem), while the highest biomass content in the apical part is produced by the inflorescence.
