“…The choice of salt-tolerant crops (Bhattarai et al,2020;Erkan and Özlem,2021) and reasonable fertilization (Machado and Serralheiro, 2017;Habib et al, 2023) are the most effective strategies for reducing the effect of salinity on forage cropping system. In previous study, the introduction of salt-tolerant forages, such as blue panicum, sesbania, and pearl millet, was clearly shown a positive agronomic results and demonstrated a forage potential to replace traditional practices (Hirich et al, 2021;Haq et al, 2021). Triticale (Triticosecale wittm.)…”

Managing soil salinization requires identifying a sustainable cropping system to improve soil quality by removing salts, particularly in the south Mediterranean area. The present study aimed to evaluate the efficiency of the forage crop succession containing triticale and alfalfa in removing salt from salinized calcareous soil. The experiment was conducted in field during two successive seasons. Five electrical conductivity levels of salinized soil (ECs) were tested: 0.3 (control), 0.8, 1.4, 1.8, and 2 dS m-1 (1:5extraction). The triticale was grown from November 2019 to April 2020. The alfalfa occupied the same soil from June 2020 to October 2021 (11cuts). The electrical conductivity of the irrigation water was ECi=1.1 dS m-1. The results revealed that the soil salinity and the exchangeable sodium percentage (ESP) decreased during the cropping seasons. The high ECs=2 dS m-1 and its ESP=85.2% became similar to control levels (ECs=0.25 dS m-1, ESP=5%) after the succession of triticale and fourth cuts of alfalfa. The NaCl uptake at the end of the cropping succession was 1433 kg ha-1 at an initial ECs=2 dS m-1. Concerning the nutrient status of the plants, nitrogen, phosphorus, and potassium contents were invariable with ECs levels. For alfalfa, a reduction in calcium and magnesium contents was noticed with soil salinity in the first season (2020). The results suggest that the insertion of triticale and alfalfa in the forage cropping system is an efficient solution for removing salt from salinized soils to ensure sustainable agricultural production.

Sclerotinia trifoliorum, the fungal plant pathogen first reported in 2021 from Pakistan on Trifolium alexandrinum L. (Egyptian clover; an annual winter fodder crop), causing Stem and crown rot disease. About 46% to 55% incidence of this disease was recorded on E. clover cultivated in the irrigated tract of the country in 2018-19. This disease is subjecting significant crop losses and drastically reducing growth. An integrated disease management approach employing biological and chemical control was adopted to manage this wide-spreading fungal pathogen. The fungal antagonists, including Trichoderma harzianum, T. longibrachiatum, and T. asperellum Moreover, fungicides, including Thiophanate Methyl, Tebuconazole, Tubeconazole+Emdachloprid, Chlorothalonil+cymoxanil, Azoxystrobin, Pyraclostrobin+Metiram, and Mancozeb+Metalaxyl were tested under in vitro and field conditions. Among Trichoderma species, the best response was achieved by T. harzianum with 80.61% inhibition compared to control. Among concentrations of T. harzianum, the best response was achieved on 1/10 (1.24 cm) with 2.4 average No. of Sclerotia and 66% inhibition. Under filed condition experiments, the data regarding Disease severity in T. harzianum treated trays was 51.7% compared to untreated/control 73.5%. Besides disease control, the application of T. harzianum showed a significant increase in green and dry fodder weight (851 grams with 87 grams of dry weight) than untreated/control (561 grams with 55 grams of dry weight) in the fourth cut. For chemical evaluation, seven fungicides tested at three concentrations under in vitro trials among these Thiophanate methyl (0.5 cm) with 90.7% inhibition were found more effective. Thiophanate Methyl's application significantly reduced the disease severity compared to control plants with disease severity in fungicide-treated trays was 28.7% compared to untreated/control 73.5% and significant increase green and dry fodder weight (931 grams with 92 grams of dry weight) than untreated/control (561 grams with 55 grams of dry weight) in the fourth cut.
