Seed yield of guar in function of row spacing and plant density: Guar seed yield

A greater solar radiation interception by modifying row spacing and plant density allows to increase the yield potential of guar. The aim of the study was to determine the seed yield potential of guar in response to row spacing and plant density. The study was carried out in Delicias, Chihuahua duri...

A greater solar radiation interception by modifying row spacing and plant density allows to increase the yield potential of guar. The aim of the study was to determine the seed yield potential of guar in response to row spacing and plant density. The study was carried out in Delicias, Chihuahua during the spring-summer season of 2021. Four distances between rows (30, 45, 60 and 75 cm) and four plant densities (30, 45, 60 and 75 plants m-2) were evaluated. An experimental design of randomized complete blocks with three replications was used, with a 4 × 4 factorial treatment arrangement. The seed yield and its yield components were determined. There were no interaction for distance between rows x population density; a significant statistical difference was only found for row spacing. The 30-cm row spacing exceeded in seed yield (2,750 kg ha-1) the other spacings (2,001 to 2,321 kg ha-1), in which no differences were found between them. The highest production in rows at 30 cm was associated to its higher leaf area index, and therefore, with its higher solar radiation interception. Una mayor intercepción de radiación solar al modificar el distanciamiento entre surcos y la densidad de población permite incrementar el potencial de rendimiento del guar. El objetivo de este estudio fue determinar el potencial de rendimiento de semilla del guar en respuesta al distanciamiento entre surcos y la densidad de población. El experimento se realizó en Delicias, Chihuahua durante el ciclo primavera-verano de 2021. Se evaluaron cuatro distanciamientos entre surcos (30, 45, 60 y 75 cm) y cuatro densidades de población (30, 45, 60 y 75 plantas m-2). Se utilizó un diseño experimental de bloques completos al azar con tres repeticiones, con un arreglo factorial 4 × 4 de los tratamientos. Se determinó el rendimiento de semilla y sus componentes de rendimiento. No hubo interacción para distancia entre surcos x densidad de población; sólo se encontró diferencia significativa para el distanciamiento entre surcos. Los surcos a 30 cm superaron en rendimiento de semilla (2,750 kg ha-1) a los otros distanciamientos (2,001 a 2,321 kg ha-1), entre los cuales no hubo diferencia significativa. La mayor producción en surcos a 30 cm se asoció a su mayor índice de área foliar, y por lo tanto, a su mayor intercepción de radiación solar.
