The growing demand for agricultural products on the back of rising population rates and per capita consumption has presented potential avenues for the use of novel agricultural techniques such as
foliar fertilization.
En el contexto descrito, el objetivo de este trabajo fue ajustar funciones que cuantifiquen area y biomasa
foliar de la especie Nothofagus glauca, utilizando como variables explicativas el diametro a la altura del pecho, la altura total del arbol y combinaciones de ellas.
In the 'Venice' cultivar, Biostimulant I and
Foliar Fertilizer I +
Foliar Fertilizer II treatments presented percentage of fruits with more than 80% red color inferior to ethephon, but superior to the other treatments.
- T5: poda apical realizada mensalmente apos o quarto lancamento
foliar maduro;
Results further indicated that as the applied
foliar boron increases, seeds boron also linearly and significantly increased with all levels of applied zinc and showed close relationship to one another.
Las hojas se secaron a 70[grados]C por 72 h en una estufa de aire forzado marca Napco (modelo 620, EUA) y se obtuvo el peso seco de las hojas con una balanza digital marca Aslep[R] (modelo EY-2200a, Japon), para calcular el PEH = peso seco (mg) / area
foliar ([cm.sup.2]).
Realizing the importance of Zn for plant growth, the severity of its deficiency in soils and plants, and the significance of its bioavailability, an attempt has been made to optimize the most suitable levels and sources for soil and
foliar Zn application in rice in controlled conditions.
400 and 600 ppm were kept in sub plot.Olive Trees were exposed to organic boron (6% elemental boron)
foliar application.
T1=Conventional tillage with 4ploughing + 2 planking; T2= Zero tillage were kept in main plots while the combination of skip irrigation and
foliar application of 1% potash treatments i.e.
Es importante el monitoreo de la concentracion nutrimental
foliar en los frutales, ya que, entre 40 y 80% de los nutrientes que contiene el arbol se encuentra en las hojas (Menzel y Simpson, 1992) y hasta el 77% de los mismos son responsables del crecimiento vegetativo inmediato (Munoz et al., 1993); esto se debe al nivel de actividad metabolica que se da en las hojas, por lo que es importante conocer la concentracion de nutrientes en este organo a traves de las etapas fenologicas, para asi elaborar programas de nutricion con mayor precision, mediante el conocimiento de los momentos criticos de demanda nutrimental.
Foliar application of K had little or no significant effect on growth and yield determinants of control plants.
The basal and
foliar application of zinc and boron significantly affects the growth, yield and quality parameters of Kinnow (Table-2 and 3).
