“…Based on the categorization of the diversity index, it is known that the weed biodiversity at the observation site belongs to the low class (H' < 1.00) and medium class (H' > 3.00). The chemical properties of the soil analyzed in this study included soil reactions (pH), organic-C, total-N, available-P, total-P, total-K, exchangeable bases (Ca, Mg, Na, and K), base saturation, and cation exchange capacity (CEC) [12,13] soil reaction (soil acidity) shows the soil's reaction and affects the soil's ability to provide nutrients for cultivated plants. Most of the soil reactions in the study area are moderately acidic, followed by neutral and acid.…”

The study’s first phase results identified 17 species of weeds with 11 species of low index class and six species of medium index class. Based on nutrient content, there were four locations with low fertility status, SPL1, SPL5, SPL6 and SPL7. In addition, there were three locations, SPL2, SPL3, and SPL4, with moderate fertility levels. In the study’s second phase, the highest pH H2O (6.38) was obtained at a dose of 25 tons per ha of Bokashi weed and 225 kg per ha of SP-36. This treatment was significantly different from other treatments. The highest available phosphorus was detected at a dose of 25 tons per ha of Bokashi weed 225 kg per ha of SP-36, namely 28.87 ppm, which was significantly different from other treatments. Moreover, there was an increase phosphorus uptake in plant due to the application of Bokashi fertilizer and SP-36 fertilizer. P uptake increased at a dose of 25 tones of Bokashi fertilizer per ha (P3) and SP-36 fertilizer dose of 225 kg per ha (S3) with an average of 0.68 g per plant.

“…Therefore, this study embarks on a comprehensive investigation of the physico-chemical properties of soils in Chato District, specifically in the Chato-Msilale fields. Soil characteristics, such as pH, electrical conductivity, nutrient content, and organic matter, are pivotal determinants of soil fertility and, subsequently, crop performance (Yang et al, 2020;Mazur et al, 2022;Mebrate et al, 2022). Evaluating these properties provides crucial insights into the potential challenges and opportunities for cotton cultivation in the district.…”

This study assessed the effects of sowing dates and phosphorus levels on cotton performance in Chato-Msilale village in Chato District, Tanzania. The soil analysis revealed that field exhibited slightly acidic soil with normal electrical conductivity but suffered from severe deficiencies in total nitrogen and organic carbon. The same field presents common issue of low cation exchange capacity, indicating limited nutrient-holding capacity. Furthermore, both fields displayed very low levels of total nitrogen (<0.1%), signaling a nitrogen deficiency. Available phosphorus was rated as medium (16.8 mg kg−1 soil). Trace elements fluctuated and could be managed based on specific crop requirements. The factors at different levels were: (1) sowing dates – (i) 25th November 2022, (ii) 15th December 2022, and (iii) 4th January 2023; and (2) Phosphorus levels – (i) control, (ii) 20 kg P ha−1, (iii) 40 kg P ha−1, and (iv) 60 kg P ha−1. Regarding cotton growth and yield, sowing dates significantly (p < 0.001) influenced plant height, gin turnout, lint yield, number of bolls per plant, and boll weight while phosphorus levels did not exhibit significant effects. Earlier sowing dates resulted in higher yields, albeit with variations in yield components. Interactions showed that growth and yields were only numerically higher in the middle sowing date at higher levels of phosphorus applied. Overall, these insights offer valuable guidance for optimizing cotton cultivation in Chato District, emphasizing the importance of selecting appropriate sowing dates for improved yields.
