“…substituição ou associados às tradicionais adubações sintéticas, os biofertilizantes são alternativa viável e de rápida disponibilização de nutrientes, sendo utilizados na produção de diversas plantas frutíferas (Sharma et al, 2011, Dantas et al, 2015, devido ser rico em matéria orgânica, proveniente de processo fermentativo e encontrar-se em estado líquido, o que torna sua aplicação através do sistema de fertirrigação simplificada e menos onerosa (Gross et al, 2008, Ramniwas et al, 2013.

Micronutrientes foliares na goiabeira fertirrigada com biofertilizante e nitrogênio no semiárido Resumo Demandados em pequenas quantidades, os micronutrientes exercem papel fundamental para o desenvolvimento adequado das plantas e podem ser fornecidos por insumos sintéticos ou orgânicos, como os biofertilizantes. Dessa forma, um experimento foi conduzido entre julho de 2014 e agosto de 2015, na área experimental da Universidade Federal do Vale do São Francisco, Petrolina-PE, para avaliar os teores foliares de micronutrientes em goiabeira Paluma em função de fertirrigação com biofertilizante bovino e adubação nitrogenada. O delineamento experimental foi em blocos casualizados em esquema fatorial (5 x 2) referentes às concentrações de biofertilizante bovino (0, 2,5, 5,0, 7,5 e 10%) e adubação mineral com nitrogênio (50% e 100% do recomendado segundo a demanda da cultura), com quatro repetições e cinco plantas por parcela. Apenas os teores foliares de Mn são afetados pelo biofertilizante bovino em goiabeiras fertirrigadas com 100% de N. Os teores foliares de todos os micronutrientes (Mn, B, Fe e Zn) não são influenciados pela fertirrigação nitrogenada. O biofertilizante é eficiente no fornecimento de Fe. Palavras-chave: Psidium guajava L., matéria orgânica, nutrição de plantas Leaf micronutrients in guava fertigated with biofertilizer and nitrogen in semiarid Abstract Required in small amounts, micronutrients play a key role for adequate plant development, which can be supplied by synthetic or organic fertilizers, such as biofertilizers. Thus, an experiment was conducted between July 2014 and August 2015, in the experimental area of the Federal University of the São Francisco Valley, Petrolina-PE, Brazil, to evaluate the micronutrient leaf concentrations of Paluma guava as a function of fertigation with bovine biofertilizer and Nitrogen fertilization. The experimental design was a randomized complete block design (5 x 2) referring to the concentrations of bovine biofertilizer (0, 2.5, 5.0, 7.5 and 10%) and N-fertilizing (50% and 100% of N dose following plant demand), with four replicates and five plants per plot. Only the leaf Mn concentrations are affected by bovine biofertilizer in guava trees fertigated with 100% of recommended N. Leaf concentrations of all the micronutrients (Mn, B, Fe and Zn) are not influenced by nitrogen fertigation. The biofertilizer is efficient in providing Fe.

“…Furthermore, it is difficult to isolate the effects of water and N availability because water provides the medium for N uptake by roots . Drip irrigation could provide a consistent moisture regime in the soil, which might accelerate root growth and result in the optimum availability of nutrients, and hence enhance tree growth (Ramniwas et al 2013). In this study, drip irrigation and fertigation might have led to the appropriate distribution and adequate availability of nutrients and moisture in the root zone of the trees, which could have enhanced the uptake of nutrients.…”

& Key message Combined drip irrigation and fertigation significantly increased stem volume and biomass production in a poplar plantation, and showed a cumulative effect over years. The promoting effects were mainly attributable to increased nitrogen and water availability in the surface soil through the combined management. & Context Fast-growing and high-yielding poplar plantations have been identified as major commercial forests in China. Intensive management of irrigation and fertilization can greatly increase productivity of plantations. Quantitative investigations on the cumulative effect of drip irrigation and fertigation over years are quite infrequent. & Aims We aimed to quantitatively evaluate the effects of drip irrigation and fertigation plans on tree growth and productivity in a poplar plantation, and to analyze their possible cumulative promoting effect over multiple years. & Methods Treatments including nine drip irrigation and fertigation combinations, and single furrow irrigation in spring as control, were conducted in a poplar plantation for three successive years. The combined treatments consist of three irrigation levels (WP −75 , WP −50 , and WP −25 , in ascending order) and three levels of nitrogen addition (N 60 , N 120 , and N 180 , in ascending order). Soil nitrogen and water content were measured throughout the 3 years. Based on tree surveys, tree growth, volume, and biomass production were evaluated each year. & Results Nitrogen and water availability in the surface soil increased in the drip irrigation-and fertigation-treated plots. Drip irrigation and fertigation treatments resulted in significant higher growth, stem volume, and biomass productions compared to control. Biomass increments in drip irrigation-and fertigation-treated plots were 4. 8-50.0, 5.3-26.5, and 4.3-52.2% higher than control in the three experimental years, respectively, with WP −25 N 180 and WP −50 N 180 recording the highest increments. Fertigation showed cumulative effects over multiple years and the positive effects increased with the dosage. However, irrigation showed little cumulative effect and the greatest effect was obtained under medium level. & Conclusion Combined drip irrigation and fertigation greatly promoted the plantation productivity. The combined management effect varied with application plans and plantation ages, and showed a cumulative effect over years.

“…The data on fertilizer use efficiency as influenced by mulching, levels of fertilizer and their combination are shown in Table 3. [12], Samanth et al [13] reported that the interaction effect of irrigation and fertigation effect was giving significant result on both vegetative and yield parameters. Ramniwas et al [14] stated that interaction effect of 100 % fertigation with 100% irrigation giving higher yield.…”

An experiment was conducted on Guava with four treatments and viz., three levels of fertigation i.e., 100%, 80%, 60% of Recommended Dose of Fertilizer (RDF) with mulching and the control refers to drip irrigation with 100% RDF in soil application. The variety used in experiment is Cv Arka Amulya with a spacing of 3 m× 2.5 m. For fertigation purpose, water-soluble fertilizer of Nitrogen, Phosphorous and Potassium is used. The results showed that vegetative growth parameters viz., plant height, girth, number of primary branches were significantly affected and canopy spread was non-significantly affected at various stages of the plant growth. The maximum plant height (2.89 m), canopy area (2.16 m2), girth (19.78cm), number of branches (6) found in 100% RDF through fertigation with mulching at the harvesting stage of the crop. The interaction effect of mulching and fertigation showed significant effect on both the vegetative and yield parameters.
