Varied patterns of sprouting and nutrient status of sugarcane sprouts in simulated and natural saline/sodic soils across two growing seasons. AbstractSalinity/sodicity (EC/SAR) of soil arises due to combination of cations and anions, which disturbs plant metabolism. Sugarcane (Saccharum officinarum L.), ranked as a medium salt-sensitive species, is grown in Spring and Autumn seasons in the subcontinent, with differential growth behaviors in both the seasons. In this study sprouting potential, growth and tissue ionic and nutrient status in natural and simulated soil conditions were determined to compare the effects of two growing seasons and natural and simulated saline/sodic soil using salinity/sodicity tolerant (CPF-246) and sensitive (S-2003-US-778) sugarcane clones. The EC (dS/m)/SAR (sodium adsorption ratio) treatments were 4/26 and 5/30 in the selected natural field and those of 5/25 and 6/30 in the simulated soil. The data were recorded after 30 days of sowing the setts for nodal bud sprouting, length and dry mass of shoot and root, tissue ionic contents for Na , N, P, S and K + /Na + ratio both shoot and root as compared to respective controls although the reduction was greater in shoot than root. Sugarcane growing seasons had differential influence on the salinity/sodicity tolerance, since reduction in the studied parameters was greater in the autumn season. Of the two sugarcane growing media natural field conditions were more adverse than the simulated conditions. A comparison of sugarcane clones revealed that CPF-246 was more tolerant of salinity/sodicity conditions than S-2003-US-778 when grown under of the soil types and seasons. In conclusion, although natural saline/sodic fields were quite more damaging, the salinity/sodicity sensitivity in sugarcane is determined by tissue concentration of macronutrients, and the seasons have great influence on the performance of sugarcane clones.

“…The decrease in the stem diameter and the weakening of the water uptake ability of the summer maize due to salt stress resulted in the decrease of the DAGB and grain yield. Straw incorporation, as mentioned above, had an excellent performance in improving the soil properties, which can help crops alleviate the adverse effects due to salt stress [52,53]. In the present study, straw incorporation improved the distribution of soil water and enhanced the soil moisture content in the cultivated layer, which thus promoted the summer maize growth.…”

Brackish water has been utilized extensively in agriculture around the world to cope with the global water deficit, but soil salt accumulation caused by brackish water irrigation cannot be ignored. Straw incorporation has been confirmed an effective sustainable means to inhibit soil salt accumulation. An experiment was conducted in growth tanks over two consecutive growing seasons to investigate the effects of wheat straw incorporation on soil moisture and salinity under brackish water irrigation (5g NaCl L−1). Furthermore, the trial investigated the effects of three wheat straw cutting lengths (CK = 0 cm; L1 = 5 cm, L2 = 10 cm, and L3 = 20 cm) on soil water-salt dynamics and summer maize growth. The results showed that soil properties and maize yields were favorably and significantly affected by the shorter straw segments incorporated into the cultivated field (p < 0.05), as indicated in the decrease in soil bulk density (7.47%–7.79%) and the rise of soil organic matter (SOM) content (2.4–4.5g kg−1) and soil total porosity (4.34%–4.72%) under treatment L1. Meanwhile, treatment L1 produced the greatest dry above-ground biomass (14447 ± 571 kg ha−1), 100-grain weight (34.52 ± 1.20 g) and grain yield (7251 ± 204 kg ha−1) of summer maize. Soil water content in the cultivated layer increased 4.79%–25.44%, and the soil salt accumulation rate decreased significantly due to the straw incorporation and the highest value of soil moisture content (19.10%–21.84%), as well as the lowest value of soil salt accumulation rates (2.12–9.06) obtained at treatment L1. Straw incorporation with cutting length in 5 cm is the optimal choice for alleviating the adverse effects due to brackish water irrigation and improving soil properties, which could be helpful for agricultural mechanization and straw field-returning practices.

“…In the treatment that received A. brasilense without P, the average plant height was 76.37 cm and in the treatment that received A. brasilense with rock phosphate fertilization, the average plant height was 64.12 cm. The difference between treatments was 16.0% According to Mahmood and Ali, (2015), microorganisms used as biofertilizers can serve as potential tools to support agricultural production, without deteriorating soil and the environment. The soil microorganism composition is related to the presence of essential elements (Adesemoye and Kloepper, 2009).…”

Rock phosphate fertilization harms Azospirillum brasilense selection by maize

Maize is the most important crop cultivated worldwide. It needs a significant amount of nitrogen and phosphorus fertilization to maintain high yields. However, the high cost of fertilization makes production more expensive and damages the environment. The present study used Azospirillum brasilense and Bacillus subtilis bacteria in an attempt to supply nitrogen and phosphorus fertilization to a maize crop. The experiment was carried out with maize plants under greenhouse conditions with a factorial scheme (4 x 2 x 2), where the first factor corresponded to bacterial inoculation: (a) control (no inoculation); (b) A. brasilense inoculation (AZ); (c) B. subtilis inoculation (BS) and (d) inoculation with a mixture of (AZ+BS), the second factor corresponded to the presence or absence of rock phosphate fertilization and the third factor corresponded to the presence or absence of top-dressed nitrogen fertilizer. Evaluated plant parameters were height, shoot dry matter (SDM), root dry matter (RDM), and soil parameters were total colony forming units of bacteria (CFU), nitrogen, soluble phosphorus and microbial biomass carbon (MBC). Although some parameters were improved with mineral fertilization in general, the findings showed that there were many adverse effects with the use of rock phosphate fertilization and A. brasilense inoculation. When both were applied together in treatments, there was reduction in plant height, microbial biomass carbon and total number of bacteria compared to treatments without rock phosphate fertilization. These results strongly suggest that rock phosphate harms the ability of A. brasilense to promote plant growth and demonstrate the necessity of new studies to verify whether this negative effect occurs under field conditions and could reduce yields in maize crop production.
