Intercropping forage cactus with sorghum affects the morphophysiology and phenology of forage cactus
نویسندگان
چکیده
The aim of this study was to evaluate morphophysiological indices, phenology and cutting time forage cactus (Opuntia Nopalea spp.) clones intercropped with sorghum cultivars (Sorghum bicolor). experiment carried out from 2017 2018, in two cropping systems (monocropping intercropping), comprising 12 treatments, consisted three clones: ‘IPA Sertânia’—IPA, ‘Miúda’—Miu ‘Orelha de Elefante Mexicana’— OEM, a monocropping system nine combinations the cacti (cultivars 467, SF11 2502) comprise each intercropping systems. Cladodes indices were obtained: absolute growth rate, relative net assimilation rate (NAR), specific cladode area (SCAR) index rate. OEM showed higher rates at beginning cycle, compared IPA Miu. NAR monocropped OEM-2502 intercrop than under all Miu but SCAR for (monocrop intercropped). shorter duration phenophase 2, had emission during phase. Cactus-sorghum cause significant reduction cactus. Intercropping has an earlier monocropping.

Intercropping legume with cereal is an extensively applied planting pattern in crop cultivation. However, forage potential and the degradability of harvested mixtures from intercropping system remain unclear. To investigate the feasibility of applying an intercropping system as a forage supply source to ruminants, two consecutive experiments (experiments 1 and 2) involving a field cultivation t...

The sorghum-sudangrass hybrid (Sorghum bicolor x S. sudanense) is an important forage crop. However, little is known about the genetic mechanisms related to forage yield and the 4 forage yield component traits in this forage crop. In this study, a linkage map was constructed with 124 assigned SSR markers using an F2 mapping population derived from the crossing of sorghum Tx623A and sudangrass S...
