“…There was significant difference in cultivar VL1 and VL2, showing its impact on the bacterial community (Lamb et al, 2011). This is worthy of note as it shows variability within cultivar, landraces (seed vigor) (Finch-Savage and Bassel, 2016), microclimate (rainfall and irrigation), planting pattern (how many per rows) (Ihwan et al, 2019) and soil condition where each cultivar was planted on the field (which were not taken into consideration in this study). Ideally, a healthy and fertile soil is characterized by high microbial species richness, as well as an equal distribution of species throughout a soil microbial community, i.e., a combination of high Shannon-Weaver and Evenness indices (Thompson and Kao-Kniffin, 2016).…”

The diversity of microbes in the soil of plants is important for sustainable agriculture as these microbes are important in carrying out different functional processes to improve the soil and invariably plant growth. Inversely the presence of the crop also affects the types of microbial communities in the soil. In this study, bambara groundnut was grown during the planting season in South Africa, from November to March 2014/2015 and 2015/2016 and soil samples were taken after every 4 weeks after planting. Soil samples were taken 15 cm deep from 2 different landraces named VBR and VL. Microbial diversity was determined by soil microbial Carbon Source Utilization Profiles (CSUP) using BIOLOG™ GN2 plates. The abundance and richness of the soil microbes was also determined using the Shannon-Weaver and Evenness diversity indices. The diversity of the soil microbial population changed over the stages of plant growth, according to cluster analysis. Bacterial abundance and diversity were higher at 4 and 8 weeks after planting (WAP). The microbial abundance (richness index) in this study ranged from 0.64 to 0.94 with cultivar VL2 at 8 WAP being the highest while bulk soil (control), R2 was the lowest. The Shannon-Weaver index varied between 2.19 and 4.00 with the lowest corresponding to control while the highest was VL2 at 8 WAP. Carbon sources utilized by bacterial communities spread across the 96 carbon sources. The highest utilization of carboxylic acids, ester, amino acids and polymers and carbohydrates was found in the bacterial communities of the different landraces across growth stages. The highest utilization of alcohols, amides, amines, aromatic chemicals, brominated chemicals and phosphorylated chemicals was found in the control landraces. This indicates that the soil samples between 4 WAP and 12 WAP were richer in diversity of microbial species and their abundance. This soil diversity and richness is an indicator of the quality of the soil in order to increase crop yields and agricultural production.

The use of inorganic fertilizers with high doses is not recommended in the sustainable maize production program. The present study aimed to evaluate soil chemical properties and growth of maize plants treated with several types of manure to reduce the use of chemical fertilizers in sandy soil. An experiment was conducted in dryland with pumped deep-well water in Gumantar Village, North Lombok Regency, from May to July 2021. There were three types of manure tested: cow, poultry, and goat manures (20 ton/ha) treated with and without BeKa decomposer. All the manure treatments received 75% of chemical fertilizers applied in the control treatment (500 kg of urea and 380 kg/ha of NPK Phonska). The treatments were arranged in a randomized block design with three replicates. The results showed that the poultry manure treatments, with and without decomposer, increased soil pH significantly. This increase improved soil chemical properties, such as available P and K. Plant height, stem diameter, leaf area index at silking, and total N in leaf tissue, were not significantly different among the treatments. These results showed that the application of manures, with or without decomposer, could substitute 25% of the inorganic fertilizers needed by maize plants grown in sandy soil.
