Sugarcane Yield

A cana-de-açúcar (Saccharum spp.) vem sendo cultivada no Brasil para produção de açúcar e agroenergia. Em seu sistema de produção, após um ciclo de 4 a 8 anos, é possível a rotação com plantas de cobertura, antes do seu replantio, para melhoria do solo e geração de renda. Estudou-se a caracterização e produtividade de biomassa de leguminosas (como adubos-verdes) e girassol (Helianthus annuus L.), a ocorrência natural de micorrizas, o teor de açúcar e a produtividade em colmos da cana-de-açúcar IAC 87-3396 e a viabilidade econômica desse sistema com cultivo após as opções de rotação, com quantificação da produtividade durante três cortes consecutivos. O amendoim (Arachis hypogaea L.) cv. IAC-Caiapó, girassol cv. IAC-Uruguai e mucuna-preta (Mucuna aterrimum Piper and Tracy) foram as culturas que apresentaram maior percentagem de colonização por fungos micorrízicos. O girassol foi a planta de cobertura que mais extraiu nutrientes do solo, seguido por amendoim (Arachis hipogaea L.) cv. IAC-Tatu e feijão-mungo (Vigna radiata L. Wilczek). A colonização por fungos micorrízicos mostrou correlação positiva com a altura de plantas de cana no primeiro corte (p = 0,01 e R = 0,52), mas não se correlacionou com a produtividade de colmos ou açúcar. No primeiro corte, o girassol foi a cultura de rotação que ocasionou o maior aumento de produtividade, da ordem de 46% em colmos e de 50% na quantidade de açúcar, em comparação com a testemunha. Com exceção dos amendoins, todas as culturas em rotação aumentaram a renda líquida do sistema na média de três cortes de cana-de-açúcar.

Organic And Inorganic Fertilizers

The present investigation aims to study the comparative effect of different treatments of organic and inorganic fertilizers on the growth and biochemical constituents of groundnut (Arachis hypogaea L.). The plants were raised in the field with different treatments of fertilizers like arbuscular mycorrhizal fungi (AMF), Azospirillum (AZM), market waste compost (MWC), nitrogen (N), phosphorus (P) and potassium (K). The plant samples were collected after 15, 30, 60 and 90 days for the measurement of different growth parameters. The analysis of the morphological and biochemical parameters such as shoot and root length, fresh and dry weight, total leaf area, chlorophyll ‘a’ and ‘b’, total chlorophyll, amino acids, starch and total sugar was made at different days intervals. The effect of organic and inorganic fertilizers on growth parameters and biochemical constituents of leaves was significantly increased in all the treatments. In general, bio-fertilizer applications are to boost the effectiveness of Arbuscular Mycorrhizal Fungi (AMF), Azospirillum (AZM) and market waste compost (MWC) on nodulation and yield of groundnut. The organic fertilizers treated plants showed better performance than the inorganic fertilizers and control.

Abstract Background Despite significant limitations of growth medium reuse, a large amount of organic substrate is reused in soilless cultivation of horticultural crops in China. Arbuscular mycorrhizal fungi (AMF) can promote nutrient absorption and improve plant tolerance to biotic and abiotic stresses. However, the mechanisms governing the effects of AMF on crop growth in organic continuous cropping substrates have not been elucidated. Results In this study, we showed that the inoculation of AMF in continuous cropping substrates promoted growth and root development, and increased the root and NADP-malic enzyme (NADP-ME) activity of tomato seedlings. Root transcriptome analysis demonstrated that the plant hormone signal transduction pathway was highly enriched, and 109 genes that positively correlated with the AMF-inoculated plant phenotype were obtained by gene set enrichment analysis (GSEA), which identified 9 genes related to indole acetic acid (IAA). Importantly, the levels of endogenous IAA in tomato seedlings significantly increased after AMF inoculation. Furthermore, the application of AMF significantly increased the expression levels of NADP-ME1 and NADP-ME2, as well as the activity of NADP-ME, and enhanced the root activity of tomato seedlings in comparison to that observed without inoculation of AMF. However, these effects were blocked in plants treated with 2,3,5-triiodobenzoic acid (TIBA), a polar transport inhibitor of IAA. Conclusions These results suggest that IAA mediates the AMF-promoted tomato growth and expression of NADP-MEs in continuous cropping substrates. The study provides convincing evidence for the reuse of continuous cropping substrates by adding AMF as an amendment.

ABSTRACT  The objective of this research was to study the growth and production of peanut at phosphate fertilization and vesicular-arbuscular mycorrhizal fungi (MVA) inoculation. This research was conducted in green house and Laboratory of Plant Physiology and Breeding UNDIP, and Laboratory of Micology UGM from April 16th to August 15th 2017. The research was assigned in completely randomized factorial design with the first factor was the phosphate fertilization control, Triple Super Phosphate (TSP) and rock phosphate (BP) and second factor was without vesicular-arbuscular mycorrhizal fungi (MVA) inoculation and with vesicular-arbuscular mycorrhizal fungi (MVA) inoculation. The results showed that TSP fertilizationhad significant effect onplant height, number of pods, weight of pods, weight of seed and total P content of soil. Fertilization of BP had significant effect onnumber of pods, weight of pods, weight of seed, total P content of soil and total P of peanut hay. Inoculation of MVA had significant effect onplant height, number of pods, weight of pods, weight of seed, total P content of soil, percentage of colonization on plant roots and number of MVA spores.Keyword: peanut, vesicular-arbuscular mycorrhizal fungi, phosphorus fertilization ABSTRAK Penelitian bertujuan untuk mengkaji pertumbuhan dan produksi tanaman kacang tanah (Arachis hypogaea L.) pada berbagai jenis pemupukan fosfat dan inokulasi cendawan mikoriza vesikular-arbuskular (MVA).
