Use of limestone and agricultural gypsum in cauliflower crop management and clubroot control in mountain farming

Abstract

The effects of the dose and application method of limestone - broadcast or in furrow - and of agricultural gypsum on soil fertility, the control of clubroot, and cauliflower development in mountain farming areas were evaluated. Initially, four doses of broadcast limestone (0.0, 1.0, 2.0, and 4.0 Mg ha-1) and two cauliflower cultivars (Sharon and Piracicaba Precoce) were analyzed. A second experiment evaluated limestone (4.0 Mg ha-1) application treatments: broadcast and in furrow, broadcast limestone + gypsum (3.0 + 1.0 Mg ha-1), and broadcast gypsum (1.0 Mg ha-1). Soil fertility was improved, and significant increases were observed in the total and healthy root volume with increasing doses of limestone. With 4.0 Mg ha-1, a 58 and 85% increase in yield was observed in Sharon and Piracicaba, respectively, compared to the control. Treatments with limestone and limestone + gypsum, regardless of the application method, elevated pH (≥ 10%), base saturation (V%) (≥ 37%), and calcium (Ca) contents (≥ 100%), and reduced the levels of aluminum ions (Al3+) (≥ 60%) and clubroot severity (≥ 64%) and favored biomass accumulation (≥ 27%) and yield (≥ 9.2%). The application of limestone in the furrow yielded results similar to the broadcast application.

Bacterial composition in brassica‐cultivated soils with low and high severity of clubroot

“…As the chemical and genetic control of clubroot is still restricted, management practices such as crop rotation, elevation of pH and Ca levels and adequate management of soil moisture are the most important strategies to reduce the losses caused by the disease (Santos et al, 2020; Bhering, Carmo, Matos, Lima, & Sobrinho, 2017; Gossen, Kasinathan, Deora, Pengm, & Mc Donald, 2016; Dixon, 2014). Most control strategies aim to affect the P. brassicae phase in the soil, either by reducing the number or viability of resting spores or by inhibiting its germination or the activity of the primary zoospores, liberated with resting spores germination.…”

Influence of molybdenum application on soil nutrient status and uptake by cauliflower (Brassica oleracea var. botrytis L.) in an Acid Alfisol soil

“…Similar results showing an increase in marketable yield/plant with Mo application when compared to the individual plots treated with NPK, NPK + FYM, NPK + Lime, and NPK + Lime + FYM have also been reported in pigeonpea and broccoli (Reddy et al, 2007;Chowdhury and Sikdar, 2017). The higher yields in these treatments might be due to the constructive role of FYM in improving the soil health and increasing the nutrient content of soil in cauliflower (Chander and Verma, 2009) and role of lime in increasing the availability of nutrients by positively affecting the soil pH in cauliflower (Santos et al, 2018). Among treatments comprising of Mo application (soil or foliar), curd yield in foliar sprayed treatments (T7 and T8) was higher to the basal applied treatments (T5 and T6).…”

Unveiling the Geological Significance and Industrial Application of Limestone: A Comprehensive Review

“…However, limestone is only utilised as a carrier when making calcium ammonium nitrate fertiliser. Additionally, grease and silica bricks are made from limestone, which helps raise crop yields and improve soil quality (Santos et al, 2020). Limestone resources have economic worth that goes beyond their use in industry; they also support the growth of regional infrastructure and economies (Limestone coast economic diversification, 2012).…”
