Physical quality of some types of grass on mixed planting with Arachis pintoi and organic fertilizing

Abstract

Increased livestock productivity is largely determined by the availability of sufficient forage. Good forage is determined by digestibility, which is related to physical quality. This study aims to determine the physical quality of several types of grass planted with Arachis legumes and the provision of organic fertilizer. This study used a Randomized Block Design with a factorial pattern consisting of 3 types of grass planted with Arachis legumes (factor A) and fertilizing 2 types of solid and liquid organic fertilizer (factor B) with 3 replications. The treatment combinations are: R1C (Paspalum notatum with Arachis pintoi+Compost), R1B (Paspalum notatum with Arachis pintoi+Biourine), R2C (Paspalum conyugatum with Arachis pintoi + Compost), R2B (Paspalum conyugatum with Arachis pintoi +Biourine), R3C (Axonopus compresus with Arachis pintoi+Compost), R3B (Axonopus compresus with Arachis pintoi+Biourine). The results showed no significant difference (P>0.05) both in the mixture of some grass plants with Arachis pintoi and the provision of organic fertilizer on the physical quality of forage. In planting a mixture of Axonopus comprsus grass with Arachis pintoi showed average dry matter (DM), water regain capacity (WRC), and water solubility (WS). Whereas compost gets higher average values than biourine for dry matter, WRC and WS. The combination of mixed planting and fertilizing, compost showed the highest average, especially water solubility (WS). From this research it can be concluded planting a mixture of grass and legumes fed with compost on average is better for the physical quality of the grass, but not significantly different (P>0.05) from all treatments.

REML/BLUP methodology for selection intraspecific hybrids of Paspalum notatum Flügge by multivariate analysis

“…Paspalum notatum Flügge, a native perennial grass species in South America, holds significant prominence within the genus (Chen et al 2022). Its distribution primarily encompasses tropical and subtropical regions (Silveira et al 2014), where is has greater economic importance (Fachinetto et al 2021), particularly in terms of forage utilization and ground cover (Blount & Acuña 2009, Wawu et al 2021. This grass species is renowned for its high forage yields (Steiner et al 2017, Machado et al 2019, making it a valuable resource.…”

Genetic Parameters, Prediction of Gains and Intraspecific Hybrid Selection of Paspalum notatum Flügge for Forage Using REML/BLUP

“…Paspalum notatum Flügge is the main constituent of natural pastures in South America [2] and is a native perennial grass [3]. In addition to being cultivated as fodder and cover all over the world [4,5], it has high forage yield [6,7] and is of wide economic importance [8]. Furthermore, when intercropped with legumes, the dry matter production of P. notatum was similar to when fertilized with 240 kg N ha −1 [9].…”
