“…For tassel length (cm), tassel primary branch length (cm) and tassel weight (g) T 5 revealed maximum (32.93), (20.7) and (9.42) respectively. Whereas T 4 (19.86) is significant for branch length and T 6 (32.36) is significant for tassel length respectively [20] found similar outcomes [21] found in his studies that intercropping Cowpea with Maize helped in gaining height of plant therefore an increment in the length of tassel. Maximum test weight (g) was recorded in T 5 (43.33) and minimum from T 1 (38.57) [22] did similar studies.…”

The current study evaluated the impact of intercropping Cowpea and Moong bean on Maize yield and its constituent parts. Nine different treatments were used in the experiment viz., (T1) sole Maize, (T2) sole Cowpea, (T3) sole Moong bean, (T4) Maize + Cowpea (1:1), (T5) Maize + Cowpea (1:2), (T6) Maize + Cowpea (1:3), (T7) Maize + Moong bean (1:1), (T8) Maize + Moong bean (1:2) and, (T9) Maize + Moong bean (2:1) in a randomized block design with three replications in Kharif season. The findings showed that intercropped plants had greater potential and produced higher values for the majority of the studied criteria, including plant height, chlorophyll meter reading (SPAD) number of cobs plant-1, number of rows cob-1, number of grains row-1, 100-grain weight, and straw and grain yields Intercrop’s seed yields were less in intercropped treatments than sole Maize. (T5) Maize + Cowpea (1:2) was best treatment having highest yield (5915.83 kg ha-1), maximum LER (1.8) and MEY (kg ha-1) (11663.36). This clearly demonstrated the advantages of intercropping Maize with legumes. This is because the leguminous crops can provide additional nutrients to the Maize crop through biological nitrogen fixation (BNF). Additionally legumes can improve the declined soil productivity by enhancing the overall soil conditions like chemical, biological, and physical. The increased availability of nitrogen and enhancement in soil physical, chemical and biological properties can improve Maize growth, leading to higher yield. Additionally it boosts soil conservation by providing more ground cover than mono-cropping.

“…Similar increases in wheat yield within intercropping systems have been observed by Hu ňady and Hochman [45], who reported higher grain yields when wheat was intercropped with faba beans. Furthermore, Chhetri et al [46] documented a 40% yield increase when wheat was intercropped with beans. This cropping system's benefits in terms of enhancing cereal grain yields were reinforced by studies on wheat-maize intercropping, bean-maize intercropping [47], and cowpea-maize intercropping [48].…”

Cereal–legume intercropping systems are not well studied under the semi–arid conditions of Southern Tunisia. Therefore, the present study aimed to investigate the effect of intercropping durum wheat (Triticum turgidum ssp. durum L.) with chickpea (Cicer arietinum L.) on crop grain yield and soil physicochemical proprieties such as carbon (C) and nitrogen (N) availability, microbial biomass nutrients (C and N) and plant nutrient content (N) in comparison to their monocultures. Field experiments were conducted during the 2020–2021 (EXP–A) and 2021–2022 (EXP–B) seasons in Medenine, Tunisia. The results revealed a significant augmentation (p < 0.05) in the total nitrogen proportions (Ntot) within the soil of intercropped durum wheat (DuWh–IR) compared to its monoculture (DuWh–MC). The observed variations amounted to 32% and 29% during the two growing seasons, identified as EXP–A and EXP–B. Additionally, the soil of intercropped durum wheat (DuWh–IR) significantly (p < 0.05) accumulated more total carbon (Ctot) than the monocrop (DuWh–MC) for both experiments, showing an increase of 27% in EXP–A and 24% in EXP–B. Simultaneously, the N− uptake of durum wheat significantly increased under the effect of intercropping, showing a rise of 26% in the EXP–A season and 21% in the EXP–B season. Similarly, the yield of durum wheat crops was comparatively greater in the intercropped plots as opposed to the monoculture crops, with variances of 23% in EXP–A and 20% in EXP–B. Intercropping cereals and legumes has the potential to enhance the soil fertility and crop production in the semi–arid regions of Southern Tunisia and contribute to environmental sustainability by reducing reliance on nitrogen fertilizers.

“…Regarding maize plant densities effect, the greater plant density of maize (100%) produced the highest grain and stover yields/fed in comparison with 75 and 50% of recommended density in both seasons. In this respect, many researchers reported that a reduction in maize grain yield/ha was obtained by intercropping maize with other crops such as millet El-salamouni, 2016 andSelim, 2018), fodder maize (Shaalan et al, 2015 andAmanullah andNivethitha, 2020), as well as a depression in stover yield/ha of maize was recorded by intercropping maize with fodder maize (Amanullah and Nivethitha, 2020) and cowpea (Chhetri and Sinha, 2020). Also, other researchers found that grain yield of maize /unit area was increased by increasing plant density of maize up to 100% when it was intercropped with groundnut (Ibrahim et al, 2019).…”

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.
