“…Häner and Barbant (2006) showed that the impact of mineral N fertilizer on the yield variation (32%) of winter wheat was comparable to that for environmental conditions (35%). In the current study, larger amounts of mineral N fertilizer led to high and stable wheat yields with relatively low production risks, which was also observed in other comparable LTEs by Varvel (2000), Chloupek et al (2004), Hao et al (2007), Lollato et al (2019) and Macholdt et al (2019a). A possible reason for this is that the mineral N buffered against environmental change.…”

The development of resilient cropping systems with high yield stability is becoming increasingly important due to future climatic and agronomic challenges. Consequently, it is essential to compare the effects of different agronomic management practices, such as cropping sequences and nutrient supply, on the stability of crop yields. Long-term experiments are a valuable resource for investigating these effects, as they provide enough time to accurately estimate stability parameters. The objective of the current study was to compare the effects of different cropping sequencing (#1: continuous v. rotational), fertilization (#2: mineral v. organic) and straw management techniques (in the case of continuous wheat; #3: removal v. incorporation) on the yield stability of winter wheat; yield risk (the probability of yield falling below a threshold yield level) and inter-annual yield variability were used as stability indicators of the effects. Long-term yield data from the Broadbalk Wheat Experiment (Rothamsted, UK) were analysed using a mixed model. Overall, the results showed that rotational cropping combined with sufficient mineral N fertilizer, with or without organic manure, ensured stable wheat yields while reducing yield risk. In contrast, higher yield risks and inter-annual yield variabilities were found in continuous wheat sections with less mineral N fertilizer or with organic manure only.

“…The average concentrations of N in leaves of the legumes (32-38 g kg −1 ) were in accordance with the values reported by Rao et al (2005) for forage soybean. The lower leaf N concentrations in tepary bean varieties could be explained by N dilution in their higher leaf biomass, as was observed in wheat (Lollato, Figueiredo, Dhillon, Arnall, & Raun, 2019). While the differences in N concentrations of both leaves and stems between two growing seasons could be due to the influence of biomass incorporation from the previous growing season or differences in rainfall patterns (Raun et al, 2019).…”

Summer forage capabilities of tepary bean and guar in the southern Great Plains

et al. 2020

Low nutritive value of perennial warm‐season grasses often causes limitation to stocker cattle production in the U.S. southern Great Plains (SGP). Exploration of novel legumes capable of generating nutritious summer forage is required to fill forage deficit periods. This 2‐yr field experiment compared the seasonal changes in forage biomass, leaf/stem ratio, and chemical composition of three varieties each of tepary bean [Phaseolus acutifolius (A.) Gray] and guar [Cyamopsis tetragonoloba (L.) Taub.] to soybean [Glycine max (L.) Merr.]. Tepary bean cultivar Black outperformed soybean and guar varieties by producing 18–48% greater aboveground dry matter (ADM) amounts (6537 kg ha−1) with a leaf/stem ratio of 3.1 at 65 days after planting (DAP). The ADM and leaf nutritive value of soybean were not surpassed by the other five tested legumes, but had the least digestible stems with an in vitro true digestibility (IVTD) of 529–581 g kg−1 in both years. Guar varieties maintained a lower leaf/stem ratio (1.3–1.5 kg kg−1) throughout the growing season, which could limit its value for grazing compared to other legumes. We concluded tepary bean could serve as an alternate forage option to soybean for producers in the SGP. Tepary bean possessed the greatest capabilities for producing adequate biomass yields with superior and consistent nutritive value when grown as a summer forage. Future research should focus on defining management practices for growing tepary bean in extensive production settings for grazing or hay.

“…The better growth of P 2 O 5 -fertilized plants can be attributed to the P readily available for absorption after being added to the soil as verified by the linear increasing response in P content in soil to P 2 O 5 application rates. Phosphorus plays important roles in plant nutrition and development (Lollato et al, 2019), for example composition of adenosine triphosphate (ATP). In addition, P is responsible for the storage and transport of energy for endergonic processes, such as the synthesis of organic compounds and the active uptake of nutrients (Marschner, 2012).…”

The use of plant growth promoting bacteria (PGPB) that can solubilize phosphorus (P) has shown potential to improve nutrient availability in grass crops such as corn (Zea mays L.) This study was developed to investigate if inoculation with Azospirillum brasilense, Bacillus subtilis or Pseudomonas fluorescens associated with P 2 O 5 rates can improve phosphorus use efficiency (PUE) reflecting on greater corn development and yield. The field trial was set up in a Rhodic Hapludox under no-till system under Savannah conditions, in a completely randomized block design with four replicates. Treatments were tested in a full factorial design and included: (i) five P 2 O 5 rates (0 to 105 kg ha −1) and (ii) four PGPB seed inoculation (Control-without inoculation, A. brasilense, B. subtilis or P. fluorescens). Inoculation was found to increase grain yield by 39.5, 29.1, and 15.9% when B. subtilis was inoculated in the absence of P 2 O 5 rates and associated with 17.5 and 70 kg P 2 O 5 ha −1 and by 34.7% when A. brasilense was inoculated with application of 105 kg P 2 O 5 ha −1. In addition, inoculation with B. subtilis and A. brasilense were found to increase P uptake, benefiting productive components development, leading to an improved PUE, and greater corn grain yield. The results of this study showed positive improvements in P uptake as a result of B. subtilis and A. brasilense inoculation, with an increase of 100.5 and 54.6% on PUE, respectively; while the P. fluorescens inoculation were less evident. Further research should be conducted under biotic or/and abiotic conditions such as attack of pathogens and insects, drought, salinity, water flooding, low and high temperature to better understand the role of PGPB, inoculated alone or in combination as the co-inoculated method.
