“…These results are also reported by Ajala et al (2019), who state that maize in intercropping systems with lima beans is more productive since it shows a LERt of 1.95 compared to monocultures of these species.…”

“…Therefore, a significant increase in yield was observed compared to the SMxHB and SMxIB crops. In this regard, Ajala et al (2019) observed a reduction in grain yield between 262.20 and 908.9 kg ha -1 in beans in association with maize. When analyzing the total production of both species, the SMxIB association reached 9767.5 kg ha -1 , which was higher than that of SMxHB with a yield of 8897.5 kg ha -1 (Table 2).…”

“…Crops grown in association play an important role in the development of sustainable agriculture and world food production (Yang et al, 2017) due to several advantages, such as the increase of total productivity per unit area by optimization of land, water, and labor resources. Additionally, these systems contribute to soil conservation by improving crop fertility and reducing harvest time by up to 25% (Ajala et al, 2019). According to Tsubo & Walker (2002), association systems increase yields compared to monocultures.…”

Polycultures are of great importance in conventional agriculture in the tropical zone, where they are a sustainable source of food production. In this study, the biomass distribution, crop yield and competition were determined in the maize and bean association. The total dry biomass accumulation of maize plants of the monoculture Simijaca SM(o) was higher than that of beans of monocultures cultivars Iraca IB(o) and Hunza HB(o). In monoculture, cultivar Iraca obtained the highest bean yields reaching 2744.0 kg ha -1 in the municipality of Gama, whereas cultivar Simijaca had the highest yields with a value of 7766.7 kg ha -1 . In the association, the best environment was the municipality of Simijaca for the SMxIB treatment, which showed a total yield of 9767.5 kg ha -1 . The total land equivalent ratio (LERt) was higher than 3.65, showing the advantage of this association. Additionally, the competitive ratio (CR) of the crops showed the high competition effect between maize and the two bean cultivars. The study generated new knowledge about the genetic resources of maize and climbing beans grown at the same time and in the same place, in the search for sustainable and resilient production.

“…These results represent the role of fertilisers to increasing yield therefore, LER and merits of intercropping when compared to sole cropping in terms of the utilisation of resources for improved plant growth and efficient land utilization. In this context, there were higher LER values, irrespective of the fertiliser level applied as well as the improvement in intercropping relative to sole cropping [60].…”

Effects of Cowpea-Amaranth Intercropping and Fertiliser Application on Soil Phosphatase Activities, Available Soil Phosphorus, and Crop Growth Response

et al. 2020

Low available soil phosphorus (P) is associated with its immobility, which renders it unavailable for plant uptake. In addition, farmers normally apply inorganic fertilisers to legumes to activate soil-bound phosphorus using root exudates. Sufficient soil mineral nutrition is key to sustainable crop production, and hence food and nutritional security. The aim of this study was to quantify the acid and alkaline phosphatase activity as an indicator of P supply and availability under varying levels of nitrogen, phosphorus and potassium (NPK) fertilization and different cropping systems. An intercropping (cowpea and amaranth) and fertiliser (control, 25%, 50%, and 100% of the recommended NPK levels) field trial was laid out in a 2 × 4 factorial treatment structure in a completely randomized design (CRD) with four replications. There was higher acid and alkaline phosphatase activity in the rhizosphere of cowpea and amaranth grown as sole crops compared to those from intercropping. The cowpea and amaranth plants grown without fertiliser or 25% NPK had the highest rhizospheric phosphatase activity, while 100% NPK application exhibited the least. The markedly higher phosphatase activity from the low fertiliser application treatments indicates the possible stimulation of microbial activity to supplement P demands for the crops. The study revealed that the application of lower rates inorganic fertilisers in a legume intercrop stimulates the activity of the phosphatase enzymes, which can subsequently liberate soil-bound phosphorus. Plant tissue phosphorus concentration of cowpea and amaranth plants increased proportionately to the increase in fertiliser application up to 50% of the recommended NPK level. The land equivalent ratio (LER) was greater than 1, indicating that it is more beneficial to intercrop cowpea and amaranth as opposed to growing them as sole crops. Overall, the application of NPK fertilizer to amounts of up to 50%, based on the results of this study, appear to be better than 100% in terms of biomass accumulation and phosphate activity.

“…The importance of using wood ash with K supplier has been demonstrated in studies. Ajala et al (2019), report that wood ash increased the yield of maize and lima beans. Bonfim-Silva et al (2019) showed that wood ash increased the pH of the soil to adequate values and made K available, resulting in better initial development of cowpea and Bhutia et al (2019) find excellent yields for growing peas.…”

The organic food production and mainly the demand for these products have been growing much worldwide, and with this rising demand there is need for more adequate soil management. Organic fertilization is one of the points to improve and the alternative sources of nutrients should be better evaluated. Potassium is an essential nutrient required in large quantities by greenery and fruit, but according to the legislation of organic production, it can only be used as crushed rocks such as potassium sulfate. The objective of this work was to evaluate the efficiency of potassium sulfate (soluble source), wood ash and marble powder as alternative sources of potassium in organic system, using hybrid maize AG 1051 as the indicator crop. The experimental design applied was in randomized blocks in the 3x4x2 factorial scheme, consisting of three potassium sources applied in four doses (0, 60, 90 and 120 kg ha-1 K2O) in the presence and absence of Biofertilizer, with four repetitions. The data were submitted to analysis of variance (ANOVA) and the averages were compared by the Tukey test (p < 0.05). Both wood ash and marble powder tested can be used as complementary potassium fertilization in organic production systems. Marble powder proved to be the most efficient among the treatments and the Biofertilizer did not have a significant effect on the evaluated characteristics.
