“…Besides that, the harvest index was reduced by 50% with the highest salt concentration (6.8 dS m -1 ). Cruz et al (2018), also report that the increase in salinity to 6.8 dS m -1 in cassava hampered the absorption of phosphorus, potassium, magnesium, and sulfur, except nitrogen. Therefore, the soils of all areas had EC within the tolerable range for cassava and without reducing the absorption of nutrients, that is, below this value.…”

Although cassava is an undemanding crop in terms of soil chemical fertility, the scarcity of nutrients affects crop productivity, and it is common to cultivate it in soils with low natural fertility, as occurs in Coastal Tablelands. In this context, the present study aimed to evaluate the physical and chemical attributes of soils cultivated with cassava under different managements. The study was carried out in the municipality of São Felipe, located in the landscape unit of Coastal Tablelands, Bahia state, Brazil. Fifteen properties were selected to evaluate the characteristics of soils cultivated with cassava under different types of management. Soil sampling was carried out during the months of October and November 2018, a dry period in the region. The medium-textured soil was predominant in the different areas of management of cassava cultivation. Most areas showed pH below the recommended range for cassava (5.5 to 6.5), base saturation below 50% and low phosphorus, potassium, calcium, and magnesium contents, according to the crop’s nutritional needs. The first two principal components explained 84.65% of the total variance. Thus, it was possible to verify that the diversity of management of cassava production areas results in high or very high variability of soil chemical attributes. The attributes pH, P, Al, H + Al, V, CEC and OM are the most representative in the distinction of soils of the cassava cultivation areas evaluated.

“…However, Na is nonessential for crop growth and development [30] and, thus, its increased uptake is a harbinger of poor crop growth and yield. In fact, a study by Cruz et al [38] found abnormally higher Na:K ratios in the tissues of cassava grown in saline soil than those of the cassava grown in a normal soil.…”

“…The attenuation of crop growth and yield under NaCl-induced salinity conditions is caused by a miscellany of factors. It has been demonstrated by several studies, such as Neocleous et al [37], Shrivastava and Kumar [20], and Cruz et al [38], that salinity reduces accumulations of important crop nutrient elements in the growing crops, which concomitantly reduces crop growth and yield. The high multiple r values of the negative linear relationships obtained between the NaCl content of the compost used in the present experiment and the amount of each of the macronutrients of P and K (see Figure 2b,c) that accumulated in the leaf lettuce confirm that indeed NaCl impinges on the absorption of those nutrients from the soil.…”

Mixing Sodium-Chloride-Rich Food Waste Compost with Livestock Manure Composts Enhanced the Agronomic Performance of Leaf Lettuce

Food waste generated at the consumer level constitutes a gigantic portion of the total amount of food wasted/lost and valorisation is touted as the most sustainable way of managing the generated waste. While food waste valorisation encompasses several methods, composting is the cheapest technique that can produce stabilised carbon-rich soil amendments. The food waste generated at the consumer level, however, is laden with sodium chloride. The compost produced from such waste has the potential of inducing saline and or sodic conditions in the soil, resultantly impeding proper crop growth and yield. Due to the scarcity of plausible means of eradicating sodium chloride from the food waste before composting, the idea of mixing the composted food waste with other low sodium chloride-containing composts to produce a food waste compost-containing amalgam with a high fertiliser potential was mulled in this study. The study then assessed the effects of mixing sodium-chloride-rich food waste compost with the nutritious and low sodium chloride-containing livestock manure composts on the yield and quality of leaf lettuce. Mixing food waste compost with livestock manure composts in the right proportions created mixed composts that produced a higher lettuce yield than both the pure livestock manure composts and food waste compost. The mixed composts also produced leaf lettuce with higher chlorophyll content and, thus, better marketability and lower nitrate content (with higher health value) than the pure livestock manure composts.

“…Nutrients and water are essential to develop morphological and yield character of the plants. Uptake of low input reduces the photosynthesis process and ultimately prevents the proper translocation of carbohydrate to form the yield contributing characters (Zaman et al, 2015;Cruz et al, 2018).…”

This study was conducted at farmers' field with three disperse replicas in three different places viz. Satkhira (AEZ-11), Koyra (AEZ-13), and Bagerhat (AEZ-11) of Khulna division in the Rabi season of 2019-2020 to determine salt tolerant varieties for maximizing mustard yield, as well as farmers' income. Characterization was done with six varieties namely BARI Sarisha-11, BARI Sarisha-14, BARI Sarisha-16, BARI Sarisha-17, and BARI Sarisha-18 (Canola) and a control variety Tori-7 under saline stress condition in coastal area of Bangladesh. Seed Tori-7, BARI Sarisha-11, BARI Sarisha-16, and BARI Sarisha-18 (Canola) were pingol in color while BARI Sarisha-14 and BARI Sarisha-17 were yellow. The yields range of the varieties was 1.13 to 2.09 t ha -1 and oil was 41.37 to 43.40%. Variety BARI Sarisha-18 (Canola) produced the maximum yield (2.09 t ha -1 ) followed by BARI Sarisha-16 (1.98 t ha -1 ) and BARI Sarisha-11 (1.84 t ha -1 ). Because BARI Sarisha-18 (Canola) and BARI Sarisha-16 are suitable for coastal areas, combining this variety with a coastal area cropping pattern will increase cropping intensity, which will benefit farmers both economically and nutritionally.
