Zinc and Phosphate Solubilizing by Rhizobacteria Promotes Lettuce (Lactuca sativa L.) Growth in Salty Conditions Full text
2024
Yusuf Çelik | Adem Özarslandan | Necibe Kayak
Due to climate change, the world is negatively affected by drought, temperature, salinity, and flood stress, leading to a significant decline in crop production. Lettuce is particularly significant when considering salt stress. To increase plant tolerance to salinity, various strategies are employed to support the development of agriculture. Rhizobacteria play a key role in regulating phosphorus (P) and zinc (Zn) homeostasis in plants. According to the study results, Rhizobium bacteria supported plant growth by improving the solubility of zinc and phosphate. These findings highlight the beneficial effects of plant growth-promoting rhizobacteria (PGPR) on the antioxidant system, which helps detoxify reactive oxygen species. The relationship between proline accumulation and antioxidant enzyme activities showed that PGPR inoculation enhanced the plant's defense mechanism against salt stress. In establishing this tolerance, increases in chlorophyll content, repair of membrane repair, and higher leaf relative humidity under salt stress were observed. PGPR also improved seedling height, diameter, and fresh and dry weight under stress by 70%, 51.4%, 55%, and 109%, respectively, due to the stress-mitigating effects of P and Zn. In conclusion, it is predicted that there will be a need to develop fertilization programs containing different rhizobacteria and Zn+P combinations. These programs would activate the antioxidant mechanism in saline soils, stabilize physiological processes, and positively impact plant growth.

In this study, it was to identify a method for separating the free bulgur bran from the fine bulgur during the production of bulgur. This was attempted by creating an electrostatic field using a PVC surface. It was observed that the issue of free bran, which adversely affects the packaged products visually, was effectively solved by this method. In contrast to conventional techniques, an alternative methodology was employed which utilizing a device comprising a folded PVC surface (folded curved channel). The configuration of the experimental apparatus was developed with dimensions of 4, 5 and 6 cm in width, 20, 40 and 60 cm in length, and angles of 30, 35 and 40 degrees, respectively. At the end of the PVC surface, plates were placed to create an electric field. In order to create the electric field, one of the plates was charged with a positive and the other with a negative charge. The distance between the plates was varied according to the width of the tunnel. The expected results were obtained in the layered PVC system. Consequently, a fine bulgur mixture consisting of 5 g of bran per 1000 g of bulgur was introduced into the experimental system at a flow rate of 0.89 g/s. This resulted in a notable reduction in the free bran content, which decreased from 5 g to approximately 2 g.

Effects of Heat and Drought Stress on Sustainable Agriculture and Future Food Security in Türkiye Full text
2024
Serpil Bas | Dilek Killi
This review investigates the effects of heat and drought stress on future food security of Turkish agriculture. Temperature average is expected to rise to 3.2°C at the end of the current century while annual precipitation will decline more than 10% in the west and south and rise by 20% in the north of Türkiye, implying that climate change will affect ecosystem sustainability. It is therefore crucial to develop strategies to mitigate and adapt to climate change such as adjusting the planting schedule, reduced tillage, fertiliser microdosing, pre-sowing seed treatment, and the application of growth promoting bacteria to improve tolerance to stress by comprehending how plants respond physiologically and biochemically under these stress conditions. Long-term heat stress may hinder photosynthetic electron transport, decreasing the plant's ability to make use of energy for photosynthesis. The immediate response of plants under drought stress involves closing stomatal openings to reduce water loss through stomatal conductance. Combined heat and drought stress have a greater adverse effect on plant development and production than their effects in isolation. Plant phenotyping can play a major role in “climate-proofing” Turkish agriculture through the identification and development of crop varities with improved prouctivity, climate resilience and input requirements. Digital agriculture will also improve the efficiency of Turkish agricultural systems as the adapt to a hotter drier climate. To ensure future food security and the viability of the agro-economic system in Türkiye steps must be taken to make Turkish agriculture more robust in preparation for the impacts of climate change.

Understanding cultivar responses to a new herbicide is crucial to determining appropriate herbicide use and management practices. Florpyrauxifen-benzyl is a new rice herbicide developed to control troublesome weeds in rice production. Little research has been conducted to characterize rice cultivar responses to florpyrauxifen-benzyl, and thus, a field experiment was conducted at the Pine Tree Research Station (PTRS) in 2017 and 2018 and at the Rice Research and Extension Center (RREC) in 2018 to determine rice cultivar tolerance to florpyrauxifen-benzyl as influenced by herbicide rate, the addition of imazethapyr, and rice growth stage. Another experiment was conducted in 2018 at PTRS and RREC to assess crop response when florpyrauxifen-benzyl at different rates is applied with and without malathion, a known cytochrome P450 inhibitor. Three cultivars were evaluated in both experiments: a long-grain variety “CL111,” a medium-grain variety “CL272,” and a long-grain hybrid “CLXL745.” Injury in the first experiment was higher when florpyrauxifen-benzyl was applied at 60 g ae ha⁻¹ than at the labeled rate of 30 g ha⁻¹, with the most injury being 10% when averaged over growth stage at the time of application. Generally, applications made at the 3-leaf growth stage resulted in the most injury; however, this injury was at most 14%. Additionally, there was no reduction in grain yield for any cultivar, indicating florpyrauxifen-benzyl can be used safely in conjunction with imazethapyr in imidazolinone-resistant rice. In the second experiment, there was no more than 10% injury and no reduction in grain yield, with the addition of malathion not causing an increase in rice injury. Results from these experiments indicate florpyrauxifen-benzyl can be mixed with imazethapyr and the addition of malathion will not lead to increased risk for injury to rice.

Ammal Abukari | Prince Cobbinah
Biochar is now gaining awareness as a sustainable tool for soil health improvement, boosting carbon (C) storage and the enhancement of nutrient cycling in agricultural soils. This study assesses the effects of biochar on soil respiration, pH, and electrical conductivity (EC) in savanna soils over a 45-day incubation trail in the laboratory. Four different biochar treatments (0, 2, 4, and 6 t/ha) were used in the study. The treatments were established at 26°C, and after 2, 5, and 10 days, the CO2 levels were recorded. After incubation for 0, 5, 10, and 45 days, the EC and pH were assessed. As the rate of application of biochar increased, the rate of CO2 evolution increased as well. During the first two days of incubation, the CO2 evolution rate rose by a value of 129 at 2 t/ha biochar, 146 at 4 t/ha biochar, and 168 ug CO2/g soil/d at 6 t/ha biochar above the 0 t/ha biochar. Following five days of incubation, the amounts of CO2 evolution that were higher than the control were 99 with 2 t/ha, 116 with 4 t/ha, and 120 ug CO2/g soil/d with 6 t/ha of biochar. The increase in CO2 evolution above the control treatment at 10 days of incubation was 61 with 2 t/ha, 79 with 4 t/ha, and 87 ug CO2/g soil/d with 6 t/ha of biochar. Analogously, rising patterns in CO2 emissions were noted. Throughout the whole incubation period, the biochar treatments' soil EC and pH were greater than those of the control treatment. After applying biochar, there were increases in the evolution of CO2, however after 10 days of incubation, the percentage of C evolved from the addition of biochar decreased as the rates of biochar increased. At two t/ha, four t/ha, and six t/ha, the percentage C developed was 1.74 %, 1.66%, and 0.82% of the applied biochar C, respectively. Although the CO2 evolved ratio to the total amount of biochar C typically reduced with increasing biochar rates, this study shows that the addition of biochar increases soil respiration, EC, and pH.

This study was carried out to determine the effect of different irrigation frequency and levels on silage sorghum plant for yield and quality at the Bingöl University Agricultural Research and Application Field in 2022 using the Master BMR variety as plant material. Randomized complete blocks applying the split-plots experimental design with three replications was used; four irrigation levels (25%, 50%, 75% and 100%) and four irrigation frequencies (5, 10, 15 and 20 days) were considered as treatments. Percentage of moisture replacement was determined using total moisture loss from evapotranspiration (ET). Amount of water discharged by emitters were predetermined, hence, time was used to determine the exact amount. Properties related to green forage yield, dry matter yield, crude protein ratio, crude protein yield, acid detergent insoluble fibre, neutral detergent insoluble fibre, digestible dry matter, dry matter consumption and relative feed value were investigated. Statistically significant differences between all the examined features were observed. The highest green forage yield, dry matter yield and crude protein yield were obtained from 5-day frequency and 100% level. Highest crude protein ratio from 5-day frequency and 25% level, lowest acid detergent insoluble fibre rate and highest digestible dry matter rate from 20-day frequency and 25% level, highest dry matter intake and relative feed value with the lowest neutral detergent insoluble fibre rate were observed from 25% level with 10 and 20-day frequencies. In conclusion; it can be stated that, to obtain high yield from silage sorghum, it is necessary to irrigate at 5 days frequencies and 100% level. However, high-quality product can be obtained with a 10-day frequency and a 25% level with low yield.

The study presents findings on comparative analysis of household food insecurity status among rice farmers in the Savanna and the Rainforest agro-ecological zones in Southwest States, Nigeria. Primary data were used and obtained through the administration of a well structured questionnaire. A multistage random sampling was used to select 577 rice farmers in the study area. Data were analyzed using descriptive statistics, household food insecurity access (HFIA) scale, household food insecurity access prevalence (HFIAP) scale, likert scale and linear regression model. The results revealed that majority of the rice farmer’s fall within 31-50 years of age bracket, with household size of 5-8 persons, married, with farming experiences and have small farm size. The findings from average household food insecurity access scale scores in the Savanna and the Rainforest agro-ecological zones were 4.0 (mildly food insecure) and 5.2 (moderately food insecure) respectively. The results of HFIAP indicator revealed that about 39.1% and 33.5% of respondents were classified as food secure, 8% and 13.9% were mildly food insecure, 15.1% and 22.2% were moderately food insecure and 37.8% and 30.4% were severely food insecure in the Savanna and the Rainforest agro-ecological zones respectively. The major coping strategies adopted by the respondents against food insecurity include reduce the quantity of food consumed and eating but not satisfied. The linear regression model revealed that age, sex, years in school, farm size, household size, farming experience, rice farming experience and tenure system significantly affect household’s food insecurity status. To transport from food insecure to food secure, age, sex, years in school, farm size, household size, farming experience, rice farming experience and tenure system alleviation policies are imperative.

In this study, the effectiveness of commercial essential oil mixture application in preventing calf losses due to diarrhea and on the growth, development and health parameters of calves was investigated. For this purpose, 24 newborn Simmental calves were used. Following birth, 20 ml of essential oil mixture was given orally via syringe to the calves in the treatment group after drinking milk in the morning for 5 days. The average birth weight of calves was 39.0 ± 0.72 kg. Birth weight of male and female calves were 42.3 ± 1.01 and 38.6 ± 0.96 kg respectively, the difference between groups were found significant. First month weight was 45.7 ± 1.67, 42.4 ± 1.65 kg in the control and treatment groups, respectively. There was no difference between the control and treatment groups in terms of body measurements taken at birth, but a significant difference was observed in chest circumference in favor of the control group in terms of measurements obtained at the 1st month. There was no difference between the treatment and control groups in terms of hematological parameters detected in the blood taken on the 10th day and in the 1-month period. No differences were observed between groups in terms of immunoglobulin levels (IgM and IgG). There was no effect of the commercial essential oil mixture on the fecal score of the calves included in the trial. It was revealed that the essential oil mixture does not make any difference in the growth, development and health of Simmental calves in a one-month period. In future studies on the subject, it is recommended that higher doses of the essential oil mixture be investigated.
