Forage yield and quality of intercropped corn and soybean in narrow strips

Abstract: Maize-soybean intercropping can increase forage quality with no detrimental effect on dry matter (DM) yield. The objective of this study was to compare corn-soybean intercrop in narrow strips with corn as monocrop in terms of DM yield and forage quality. This study was conducted in Matamoros, Coahuila (Mexico) in 2006 and 2007. Intercrops were established in rows spaced 0.50 m apart, evaluating alternate corn-soybean strips with one, two, three, and four rows per crop, and a treatment using an alternate twin-row planting pattern per crop, with a 1.0-m row-spacing. As control treatments, monocrops of corn in rows 0.76 m apart and soybean in rows 0.50 m apart were evaluated. A randomized complete block design with four replications was employed. Corn-soybean intercrop produced DM yields similar to those of monocropped corn due to higher corn yields in border rows adjacent to soybean. Crude protein (CP) yields per hectare in intercrop treatments were higher (27.5 to 42.8%) than those of monocropped corn, due to greater CP concentrations in intercrops (16 to 21 g kg ‐1 ). When soybean was harvested at the beginning maturity stage (R7), neutral detergent fiber concentration was reduced by 60 to 63 g kg ‐1 in corn-soybean intercropping compared to corn monocrop. Acid detergent fiber was not altered by intercropping. Results indicate that maize-soybean intercrop in narrow strips can provide forage quality advantages without affecting yield.

Effect of intercropping of corn and soybean on dry matteryield and nutritive value of forage corn

Abstract: Cereal-based forage production could be considered to have potential to supply great deal of energy-rich feed in animal diets. Experiment was conducted to evaluate effect of corn-soybean combinations of 75:25, 50:50 and 25:75 in addition to monocrops of corn and soybean to detremine forage dry matter (DM) yield and quality in corn-soybean intercropping. The crop combination ratio had significant effects on dry matter yield and nutritive quality of forage. The ratio of 75:25 and 50:50 recorded DM yields similar to those of monocropped corn (14.77 t/ha). Forage quality in terms of crude protein (CP) (75:25 ratio 12.75%, 50:50 ratio 13.73% and 25:75 ratio 14.68%) was improved by intercropping due to higher nitrogen availability for corn in intercropping compared with its sole crop (10.83% CP). Increase ratio of corn in corn-soybean mixture, negatively affectd neutral detergent fiber (NDF), acid detergent fiber (ADF) of forage and declined with increasing ratio of soybean plants. Combination ratio of 50:50 gave higher protein yield (1886.45 kg/ha) than other crop combination ratio. Among all the combination ratios, the 50:50 corn-soybean ratio was the optimum giving highest forage yield, protein content as well as protein yield.

Intercropping Maize and Faba Bean for Silage Under Swedish Climate Conditions

Abstract: Cultivation of forage maize is increasing in Sweden. Sole maize is low in protein and supplementation of protein feed is needed. This study investigated whether forage maize and legumes can be intercropped in a system suitable for farmers (simultaneous sowing and harvest) under Swedish climate conditions, and whether intercropping maize and faba bean improves the forage quality compared with sole maize. Two field experiments were performed in which maize intercropped with faba bean (Vicia faba L.) in alternate rows with 0 or 60 kg N/ha was compared with sole maize crop with 120 kg N/ha. Maize dry matter (DM) yield decreased by intercropping (from mean 14,171 kg DM/ha for sole maize to 8,888–10,791 kg DM/ha for intercropped maize). Mean yield of faba bean ranged from 2,907 to 2,966 kg DM/ha. Compared with sole maize, intercropped treatments slightly increased forage protein content (mean increase 10–15 g/kg DM). Furthermore, intercropping increased forage in vitro organic matter digestibility by 4 % units (from 80.8 to 84.7 %), while the starch concentration slightly decreased from 316 to 236–254 g/kg DM. Intercropping increased neutral detergent fibre concentration from 435 to 478–497 g/kg DM and the sugar concentration from 57.3 to 61.5–72.3 g/kg DM. The results showed that intercropping silage maize and faba beans is possible under Swedish climate conditions.

Row arrangements of maize and soybean intercrop on silage quality and grain yield.

Abstract: The success of maize + soybean intercrop depends on the plant arrangement. An experiment was carried out to evaluate different row arrangements on intercrop forage yield, silage quality and maize grain yield in relation to maize as a sole crop. The experiment was set up with a randomized complete block design with eight row arrangements between maize and Soybean. Maize biomass yield among crop arrangements were similar, although, lower than the maize sole crop. On the other hand, these treatments showed higher soybean biomass yield, which in turn increased silage crude protein and crude protein yield per unit area. Maize thousand grain weight, grain yield per plant and per area was affected by the intercrop arrangements. The use of two corn rows + two soybean rows (2M+2S-30 cm) and four corn rows + four soybean rows (4M+4S-30 cm) showed higher crude protein yield per area associated with similar maize grain yield in relation to the sole maize crop. In conclusion, alternating four maize rows with four soybean rows was the optimum row ratio in maize + soybean intercrop, though this needs to be further confirmed by more trials.

Silage yield and quality of row intercropped maize and soybean in a crop rotation following winter wheat

Abstract: Maize (Zea mays L.) intercropped with soybean (Glycine max L.) may be a viable option to improve the quality of the silage. In this study, maize and soybean intercropped in different numbers of rows and their monocropping equivalents were tested to determine the best intercropping system in a crop rotation following winter wheat. The treatments were monoculture maize (M), monoculture soybean (S), 75% maize + 25% soybean (3M:1S), 50% maize + 50% soybean (2M:2S) and 25% maize + 75% soybean (1M:3S). The experiment was laid out in a randomized complete block design with three replications in 2011 and 2012 in Antalya, Turkey. Highest fresh forage yields were obtained from maize (53.3 t ha−1) and 3M:1S (62.8 t ha−1) treatments in 2011 and 2012, respectively. Maize treatment had highest dry matter yield (21.1 and 22.0 t ha−1) in both years. Quality analysis of silage revealed that 3M:1S was superior to maize treatment in terms of dry matter (25.23%), crude protein (7.31%), crude fiber (18.27%), neutral d...

Forage Production and Nutrient Composition of Different Sorghum Varieties Cultivated with Indigofera in Intercropping System

Abstract: The experiment aimed to evaluate the production of nutrients by different varieties of sorghum grown with high valuable indigofera legume in intercropping system and to determine the suitable variety of sorghum that produced the highest nutrient in the system. The experiment was done at Jonggol Animal Science Teaching and Research Unit (UP3J) Jonggol, from November 2014 to March 2015. This experiment was conducted using completely randomized design with 2 factors (3 x 4) and 4 replications. The first factor was sorghum varieties (PATIR 3.2 (S1), PATIR 3.7 (S2), and CTY-33 (S3)). The second factor was indigofera composition (0% indigofera (I0), 30% indigofera (I1), 40% indigofera (I2), and 50% indigofera (I3)). Data were analyzed using analysis of variance and HSD test. There was no interaction among varieties of sorghum and indigofera composition. Indigofera population of up to 50% in multiple cropping system had the highest (P<0.01) dry matter content, crude protein content, ash content, total fresh weight production, total dry weight production, total crude protein production, total ash production, and carrying capacity. Sorghum variety CTY-33 planted in multiple cropping system had the highest (P<0.01) dry matter content, total dry weight production, and (P<0.05) total crude protein production. PATIR 37 sorghum variety planted in multiple cropping system had the highest (P<0.05) ash content and (P<0.01) total ash production. It is concluded that Indigofera population of up to 50% planted with different varieties of sorghum in multiple cropping system had the highest nutrient production.
