Spain is the main chickpea (Cicer arietinum) producing country in Europe, despite there are few studies on micronutrient application to chickpea. The response of chickpea to the applications of Zn, B and Mo was studied in pot experiments with natural conditions and acidic soils in northwest Spain from 2006 to 2008 following a factorial statistical pattern (5 × 2 × 2) with three replicates. Five concentrations of Zn (0, 1, 2, 4 and 8 mg Zn pot–1), two concentrations of B (0 and 2 mg B pot–1), and two concentrations of Mo (0 and 2 mg Mo pot–1) were added to the pots. Chickpea responded to the Zn, B and Mo applications. There were differences between soils. The mature plants fertilized with Zn, with B and with Mo had a greater total dry matter production. Harvest Index (HI) improved with the Zn application and with the Mo application. The highest HI was obtained with the Zn4× B2 × Mo2 treatment (60.30%) while the smallest HI was obtained with the Zn0 × B0 × Mo0 treatment (47.65%). The Zn, B and Mo applications improved seed yield, mainly due to the number of pods per plant. This was the yield component that had the most influence on, and the most correlation with seed yield. The highest seed yield was obtained from the Zn4 × B2 × Mo2 treatment (4.00 g plant–1) while the lowest was obtained from the Zn0 × B0 × Mo0 treatment (2.31 g plant–1). There was a low interaction between the three micronutrients. The Zn application was more efficient when it was applied with both B and Mo.

“…Valenciano et al (2009;2010) obtained similar results in the same environments but under pot conditions at high moisture availability; they also recorded differences for 1000-seed weight. Zn soil application increased yield (Khan et al 2000) and, as with the common bean (Valenciano et al 2007), this increase was the result of an increase in the number of pods per plant (Khan 1998;Valenciano et al 2009;2010). Although the response to Zn soil application varied with environment, as Loneragan & Webb (1993) observed, variance analysis established that the environment)Zn interaction produced no significant differences in growth and yield.…”

Chickpea (Cicer arietinumL.) response to zinc, boron and molybdenum application under field conditions

New Zealand Journal of Crop and Horticultural Science

In Spain*Europe's leading chickpea producing country*chickpea (Cicer arietinum) is mainly cultivated on non-irrigated soils with low native fertility. This study was carried out from 2006 to 2008 in the province of Leo´n, Spain, under acid soil field conditions, with the aim of determining whether the application of zinc (Zn), boron (B) and molybdenum (Mo) improved chickpea growth and yield on acid soils. A split-split-plot design with three replications was used. Chickpea responded only to the Zn and Mo applications. At maturity, plants fertilized with Zn and with Mo had a greater total dry matter production and seed yield, mainly due to an increment in pod dry matter. For Zn, the highest yield was obtained with 2 mg Zn per plant (6.80 g plant ). Interaction was observed between B and Mo, interpreted as indicating that Mo can counteract the effect of B application.

“…Furthermore, the highest yield was also obtained with treatment at 4 WAE. Yield was increased due to greater pods plant -1 number, this yield component being closely related to final seed yield (Maiti and WescheEbeling, 2001;Valenciano et al, 2009). Mo application after emergence improved yield until 4 WAE.…”

Molybdenum (Mo) plays an important role in increasing chickpea yield. In 2009, we studied the effects of different Mo application times and techniques on the response of the Kabuli chickpea (Cicer arietinum) to Mo nutrition. Pot experiments were conducted under natural conditions using two different soils from northwest Spain and following a factorial statistical pattern (7 × 2) with six replicates for each soil. A treatment of 2 mg Mo pot -1 was added to the pots at six different moments, 1 to 6 weeks after emergence (WAE), using two different application techniques (soil and foliar). Both growth and yield were affected by Mo application, but yield was more affected than total dry matter. The response was greater in the medium acid soil than in the neutral-slightly basic soil. At maturity, plants fertilized at 4 WAE produced a greater seed yield, mainly due to an increase in the number of pods per plant. Foliar Mo application was more effective, and soil Mo application should be carried out earlier in the cycle. An interaction was found between time and technique of Mo application, with the highest yield being obtained when Mo was applied at 4 WAE using foliar fertilization.Additional key words: dry matter; foliar and soil application; Kabuli type chickpea; pot experiments; yield components. Resumen Efecto de diferentes épocas y técnicas de aplicación de molibdeno sobre el crecimiento y rendimiento del garbanzoEl molibdeno (Mo) juega un papel importante en el incremento del rendimiento del garbanzo. Se estudió durante 2009 la respuesta del garbanzo (tipo Kabuli) cultivado en macetas al aire libre a las aplicaciones de Mo en diferentes épocas y utilizando dos técnicas diferentes de aplicación, usando dos suelos distintos del noroeste de España según un diseño factorial (7 × 2) con seis repeticiones para cada suelo. Se añadieron 2 mg Mo maceta -1 en seis épocas diferentes, desde la primera semana después de la emergencia hasta la sexta, utilizando dos técnicas de aplicación distintas (al suelo y foliar). El crecimiento y el rendimiento se vieron afectados por la aplicación de Mo, siendo el rendimiento más afectado que la materia seca total. La respuesta fue mayor en el suelo medianamente ácido que en el suelo neutro-ligeramente básico. En la madurez, las plantas fertilizadas con Mo a las 4 semanas después de la emergencia dieron un rendimiento mayor, principalmente debido a un aumento en el número de vainas por la planta. El aumento fue mayor en el suelo medianamente ácido. La aplicación foliar de Mo fue más eficaz; mientras que la aplicación de Mo al suelo debe llevarse a cabo en épocas más tempranas. Se encontró interacción entre la época y la técnica de aplicación de Mo, obteniéndose el rendimiento más alto cuando el Mo fue aplicado vía foliar a las 4 semanas después de la emergencia.Palabras clave adicionales: aplicación foliar y al
