“…Our results indicated that the mixed cropping of maize with legumes increased the CP of forage. Proper CP levels are essential in forages for many types of livestock that rely on them for nutrition [40]. The CFA and CA contents did not significantly differ (p > 0.05) among the maize-common bean mixture ratios, which were consistent with our results [40].…”

“…The highest DMY (14.56 t ha −1 ) was found in sole maize (100:0 seeding ratio) compared with the other mixed forages in Figure 2B. This difference in DMY contents may be due to the effect of the harvesting stage of maturity [40]. Sole maize produced higher FFY and DMY than maize intercropped with soybean [40] and cowpea [41].…”

“…This difference in DMY contents may be due to the effect of the harvesting stage of maturity [40]. Sole maize produced higher FFY and DMY than maize intercropped with soybean [40] and cowpea [41]. The high FFY in sole maize might be due to its tall plant height and leafy component, which resulted in a shading effect on the intercropped legume crops [42].…”

The changing climate, inadequate water supply, insufficient agricultural inputs, decreasing in agricultural arable land areas under forage crops of Northwestern Loess Plateau region, expanding livestock population, increasing demands for meat and milk production, and food and feed security concerns all insist on a necessary requirement in forage quality production. Cereal–legume mixed-cropping is a biological approach to enhancing herbage yield and quality of upgraded animal feed (forage and silage). However, little information exists about the appropriate mixing seeding ratios and its impacts on yield and quality. Therefore, this study was conducted to examine the forage yield and nutritional quality of maize (Zea mays L.) and common bean (Phaseolus vulgaris L.) in mono-and mixed-cropping approaches at the seeding proportions of 100:0, 75:25, 50:50, 45:55, 25:75, and 0:100 in 2019 and 2020 in Northwestern Loess Plateau region. A randomized complete block design with four replicates was used in this experiment. The results indicated that forage quality was significantly affected by the mixture ratios. The land equivalent ratio (LER) of all mixed-cropping treatments greater than 1.0, in which maize–common bean at the 50:50 seeding ratio achieved higher LER (1.46) than that of other treatments, showing that mixed-cropping combination systems are better users of land resources. Laboratory forage quality analysis and Pearson correlation analysis showed that the relative feed value had highly positive correlation with total digestible nutrients and relative forage quality in mixed-cropping treatments. Our results showed that fresh forage yield and dry matter yield were higher in monocropped maize forage than in other intercropped forages, whereas crude protein yield was lower compared with other mixed cropping forages. After 60 days of ensiling, the highest organic acid profile and ammonia-nitrogen were observed in M25:CB75 silage compared with other silages. The highest ensilability of fermentation coefficient was also found in M50:CB50 compared with other intercropped silages. Regarding forage preservation, silage showed higher contents of crude protein, relative feed value and lower crude fiber, water-soluble carbohydrate neutral detergent fiber, and acid detergent fiber contents than forage. This study determined that the ratios of maize–common bean 25:75 and 50:50 were the most desirable mixture ratios among mixed-cropped forage and silage based on chemical composition and quality analysis for livestock feeding.

“…After each mowing, a 1 m × 1 m quadrat was selected from each plot to weigh the fresh grass yield, after which the fresh grass was brought back to the laboratory. The samples were air‐dried at 105°C to inactivate the enzymes (Soe Htet et al, 2021), subsequently dried at 65°C to a constant weight and weighed to calculate the dry‐to‐fresh ratio (dry grass weight/fresh grass weight × 100%). The average daily growth rate and stem‐to‐leaf ratio were determined using a previously described method (Wang et al, 2021).…”

Paspalum dilatatum is an excellent warm-season forage grass and soil conservation plant in subtropical regions. However, information on P. dilatatum cultivation in southwestern China is limited. A preliminary evaluation of the genetic diversity and adaptability of six P. dilatatum germplasms was conducted in Guizhou based on inter simple sequence repeat (ISSR) markers and field trials. Fifteen polymorphic primers were screened from 50 ISSR primers. A total of 141 bands were generated, 124 of which were polymorphic, yielding 88.63% polymorphic bands. The number of polymorphic loci detected for the different germplasms ranged from 23 to 61, and the percentage of polymorphic loci was 40.67%. The mean number of alleles was 1.23, and the effective allele number was 1.15. Nei's genetic diversity index was 0.08. The Shannon information index was 0.12, and the genetic similarity coefficient (GSC) ranged from 0.6002 to 0.8955, indicating a relatively rich genetic base among the germplasms. The unweighted pair group method with arithmetic mean approach was used to construct the clustering map. Using a GSC of 0.83 as the threshold value, the six germplasm materials were divided into four clusters, indicating that ISSR molecular markers can be effectively applied to analyze the genetic diversity of P. dilatatum germplasms. Cluster analysis of 12 growth characteristics of the germplasms of P. dilatatum showed that germplasm 4 exhibited strong tillering ability and a high crude protein content. Germplasm 3 showed high plant height, fresh yield and hay yield. Germplasm 1 showed the lowest forage yield and crude protein content. Germplasms 2, 5 and 6 showed excellent crude protein and crude fat contents; the remaining indicators showed intermediate performance. This study provides important references for the utilization and variety selection of introduced P. dilatatum resources in the karst areas of Guizhou.

“…These results are in harmony with those obtained by Hassan et al (2017) who found that pearl millet gave the highest values of fresh and dry yields/fed followed by sudan grass and teosinte when they were grown either alone or intercropped with some legume crops. Also, many investigators found that fresh and dry forage yields/unit area of some grass forage crops were decreased when they were intercropped with some crops such as maize (Samarappuli and Berti, 2018), cowpea (Shahwan et al, 2013, Pal et al, 2014, Iqbal et al, 2017, Ginwal et al 2019and Qadir et al, 2021 and soybean (Salama andAbdel-Moneim, 2021 andSoe Htet et al, 2021).…”

The present study was carried out at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shebin El-Kom, Egypt during 2019 and 2020 summer seasons to study the influence of intercropping three summer grass forage crops, i.e. pearl millet, sudan grass and teosinte at 100% from their recommended seeding rate with maize at three densities of maize, i.e. 50, 75 and 100% of the recommended plant density (24000 plants/fed) on their productivity and quality as well as the land use efficiency and the competitive relationships. The treatments were arranged in a randomized complete blocks design with four replications. The obtained results could be summarized as follows: 1-Intercropping forage crops with maize decreased most growth characters (No. of shoots/m 2 , total chlorophyll, No. of leaves /shoot, leaf area/shoot and total dry weight/shoot, forage yield (fresh and dry forage yields/fed), chemical composition (protein% and ash %) as well as nutritive value (digestible protein "DP" % and total digestible nutrients "TDN" %), but increased plant height and fiber % of forage crops compared to their sole croppings. Sudan grass surpassed other forage crops in plant height and fiber%, while millet crop recorded the highest values of No. of shoots/m 2 , total dry weight/shoot, fresh and dry forage yields/fed. Teosinte crop exceeded millet and sudan grass in total chlorophyll, No. of leaves/shoot and leaf area/shoot as well as chemical composition (protein % and ash %) and nutritive values (DP% and TDN %). Increasing plant density of maize from 50% to 100% intercropped with forage crops increased plant height of forage crops, but caused a reduction in growth characters, forage yield as well as nutritive values of forage crops. 2-Intercropping maize with forage crops decreased yield and its attributes of maize (No. of ears/plant, No.of grains/ear, 100-grain weight, ear weight, grain yield/plant, grain and stover yields/fed, protein % and carbohydrates % in grains of maize, but increased oil %. Moreover, increasing plant density of maize up to 100% intercropped with forage crops increased grain and stover yields/fed as well as oil %, but decreased grain yield/ plant and its attributes, protein and carbohydrates % of maize. 3-The aggressivity results showed that the values of maize were positive (dominant), while the values of the three fodder crops were negative (dominated). Increasing the plant density of the maize from 50% to 100% intercropped with fodder crops also led to a decrease in the aggressivity value of the maize. The value of the competitive ratio for maize was greater than that of fodder. Increasing plant density of maize led to a decrease in the competitive ratio for maize but an increase in the competitive ratio for fodder crops. The values of the relative crowding ratio and land use efficiency were increased more than one compared to sole cultivation. The best intercropping system for obtaining the highest grain units was obtained when 100% maize was intercropped with millet or teosinte.
