“…Production efficiency was found always higher from intercrop combinations than that of sole crop cultivation (only banana). The intercrops based results supported the findings of Rahman et al (2006) and Bantie (2015).…”

An intercrop-based experiment was conducted for two consecutive years during September 2012 to October 2014 at farmer's field of MLT site, Shibganj, Bogra to find out the performance of banana intercropped with potato and vegetables. There were three intercrop-based treatments i.e. Banana + Potato, Banana + Radish + Potato and Banana + Cauliflower + Potato were tested along with Sole Banana. The results revealed that all the intercrops produced higher banana equivalent yield over the sole banana in both the years. However, among the intercrop combinations, Banana + Cauliflower + Potato provided the highest equivalent yield (104.04 tha -1 in 2012-13 and 122.50 tha -1 in 2013-14) followed by Banana + Radish + potato. Sole banana produced the lowest equivalent yield in both the cropping seasons. Higher gross margin was also obtained from the intercrop combinations. Among the intercrops, Banana + cauliflower + Potato provided higher gross margin (Tk.656898 ha -1 ) but due to higher cost, this treatment failed to show higher BCR than Banana + Radish + Potato.

“…Intercrops achieve yield advantage when the LER value is greater than 1 [40], which indicates more interspecific facilitation than interspecific competition between two component crops [35]. Land equivalent ratio value less than 1 reveals yield disadvantage [42] due to more interspecific competition than interspecific facilitation between intercrops [35]. e LER of 1 shows no difference in the production of intercrops [43].…”

Global demand for food has always been on the increase due to the increase of the population in this world. Intercropping is one of the alternatives of agronomic practices that is widely practiced in ensuring food security and enhancing yield stability. Strip, mixed, and relay intercropping can be practiced to increase crop production. In addition to achieving a successful intercropping system, factors such as suitable crops, time of sowing, maturity of the crop, and plant density need to be considered before and during planting. Besides, practiced intercropping becomes a useful cropping system to increase efficient resource utilization, enhance biodiversity, promote soil health, enhance soil fertility, erosion control, yield advantage, weed, pest, and disease control, insurance against crop failure, ecosystem and modification of microclimate, market instability, and increase farmers income. Crop productivity in any types of cropping system implemented relies primarily on the interception of photosynthetically active radiation (PAR) of crop canopy and conversion of intercepted radiation into biomass or known as radiation use efficiency (RUE). Both PAR and RUE are important measurements that have significant roles in crop growth and development in which the accessibility of these radiation dynamics is connected with the leaf area index and crop canopy characteristics in maximizing yield as well as total productivity of the crop component in intercropping systems.

“…Maize intercropping with faba bean was recommended at Adet as profitable cropping system (Tilahun et al, 2012). Intercropping potato with maize was recommended for central highlands of Ethiopia such as Holeta (Temesgen and Wondimu, 2012) in Tigray region (Beyenesh et al, 2017) in Wollo (Bantie, 2015). Rotation of maize with pulses (haricot bean, soyabean, pigeonpea), oil crops (noug), was also recommended as a best practice in Bako and similar area (Tesfa et al, 2001).…”

Agronomic panel survey was conducted in Bako Tibe district to assess current farmers maize agronomic practices and associated actual maize grain yields. The survey was conducted using 100 households. Most of the maize farms (90%) were characterized as having strongly to strongly acidic soils, low to medium SOC, medium to high TN, very low to low av.P, high to very high exch. K, low to medium exch.Ca, and medium to high exch. Mg, high av. Zn and Fe and very high Mn contents. Most farmers (94%) grow improved maize varieties and 80% of them grew a pioneering hybrid Limu and Bako hybrids BH540 and BH543. Most farmers (97%) apply different inorganic fertilizers and of them >70% of them applied NPS+Urea or NPS alone. Farmers rarely retain crop residue. Most farmers (81%) maintain lower plant density at harvest than the recommended density and the density declined from vegetative to harvesting stage. About 99% of the farmers grow sole maize, 57% rotate maize with other. Percent weed cover of the farms were 25% on average but reached as high as 80%. About 87.5%, 86%, 75% of farmers harvested grain yield that was higher than the national, regional and zonal average, respectively. Since most maize farms (90%) were very strongly to strongly acidic, there is a need to apply lime to improve maize productivity and nutrient use efficiency in the area. The poor weed and crop residue management, sole cropping of maize and lower plant densities practiced by farmers were among the gaps observed that potentially reduce maize productivity in the study area unless the extension sector intervenes. However, the current trend improved maize varieties and inorganic fertilizers use is promising and needs to be encouraged for intensification of maize production in the study area. Contribution/Originality: This paper serves as the most recent study on maize agronomy in Ethiopia in giving sight to the nutrient status of soils of the best maize growing district in the region. It also gives an insight into what the maize agronomic practices (cropping system, crop residue management fertilizer, and improved maize variety use) look like in the distinct. 1. INTRODUCTION Maize is the second most widely cultivated crop in Ethiopia and is grown under diverse agro-ecologies and socioeconomic conditions typically under rain-fed condition (Abate et al., 2015). Maize has expanded rapidly in terms of both area and production. Following the increasing trend of farmers' investment on required inputs, mainly in improved seeds and chemical fertilizers, maize productivity has also dramatically increased in Ethiopia. As a result, maize has had a positive impact on poverty reduction in many parts of the country (Abate et al., 2015).
