Chickpea production and soil chemical attributes after phosphorus and molybdenum fertilization

Abstract

Chickpea is the third most cultivated legume in the world. In Brazil, cropping of this legume is recent and definitions of fertilizer management techniques are scarce. In this study, the objective was to evaluate chickpea (BRS Aleppo) production and soil chemical attributes with and without phosphorus fertilization and leaf-applied molybdenum. A randomized block experimental design was used, with four replications. A 2 x 5 factorial arrangement was used to evaluate production, consisting of two molybdenum fertilization management practices (with and without molybdenum) and five application rates of P2O5 (0, 60, 120, 180, and 240 kg ha-1) in the form of single superphosphate. Soil sampling for evaluation of soil chemical attributes in the crop row and between rows was also considered. Molybdenum fertilization brought about greater stem and aboveground dry matter. Phosphorus fertilization increased stem, leaf, and seed yield, yielding a maximum of 2.83 t ha-1 seed at the rate of 200 kg ha-1 P2O5. However, maximum agronomic efficiency (8.30) was observed with the addition of 150 kg ha-1 P. Soil in the crop row attained higher concentrations of P, K, H+Al, and P-rem and reduction in pH, Ca concentration, SB, T, and V compared to between rows. Phosphorus rates reduced soil pH and increased T and the P concentrations, though only in the plant row. Between the rows, no changes were observed in soil chemical attributes, indicating low mobility of P and the acidification capacity of superphosphate in alkaline soils.

Effect of P Application Rate and Rhizobium Inoculation on Nodulation, Growth, and Yield Performance of Chickpea (Cicer arietinum L.)

“…Likewise, a study on response to P and Mo fertilization under irrigated conditions in chickpea revealed that the P rate increased stem and grain yield. P 2 O 5 of 160 and 200 kg ha −1 had 5.91 (stem dry matter) and 2.71 t ha −1 (grain) yield, consecutively [126]. Such grain yield was considered high against other countries, such as India, Pakistan, and Ethiopia with mean yield of 0.91, 0.47, and 1.91 t ha −1 , sequentially [152,153].…”

“…e demand for P in chickpea is relatively in large amount for growth and has been revealed to improve leaf area, biomass, yield, number and mass of nodule [125]. Several studies have signified the important role of P in the growth and production of chickpea [22,48,126].…”

Comparative Efficiency of Mineral, Chelated and Nano Forms of Zinc and Iron for Improvement of Zinc and Iron in Chickpea (Cicer arietinum L.) through Biofortification

“…The global consumption of chickpea has shown an increase of 14.2% in area and 27.3% in quantity of production since 2010 [2]. The cultivation of chickpea offers various advantages such as adaptability in a wide range of climatic conditions, low cultivation cost, and the enhancement of nitrogen fixation, thus improving soil fertility [3].…”

Effects of Farmyard Manure and Exogenous Spray of Bio-Stimulants on Seed Quality of Kabuli Chickpea

“…It is a good source of carbohydrates and protein, and protein quality is considered to be better than other pulses (Merga and Haji, 2019). Also, it is adaptable to wide climatic variation, has low production cost, and promotes biological fixation of atmospheric nitrogen (Pegoraro et al, 2018). Therefore, it is a desirable plant for inclusion in crop rotations in these areas.…”
