The present investigation entitled Effect of foliar application of boron and zinc mixture on yield of some wheat cultivars (Triticum aestivum L.). The experiment was carried out in agriculture college of Kerbala University, during winter season of 2013-2014. The experiment was laid out in split plot design with three replications and 12 treatments. The experiment consisted of Z and B mixture @ (0, 25 and 50) mg.L -1 and four cultivars Adnania, Fatih, Abu Garib3 and Tahadi, The highest number of spike/m 2 (381), Thousand grain Weight (45.68 g), Number of grain in spike (42.40) and Grain yield (6.332 megagram.ha -1 ) were recorded in 50 mg.L -1 with Tahadi cultivar , 50 mg/L with faith cultivar, 25 mg.L -1 with Abu Garib3 and 50 mg.L -1 with Tahadi cultivar respectively.
A field experiment was carried out in the fields of Ibn al-Bitar vocational prep school in Husseiniya district in Kerbala governorate during the spring season 2018 to study the role of nonopartical fertilizers on the growth of corn (5018). cwtival(R.C.B.D) was done in three replicates and in one factor, Control B1 protikculbor with 1 mL.L-1 concentrationP2 protikcalbor with 2 ml.L-1 concentration andoptimus plus B3 protikculbor with 3 mL.L-1concentrationoptimus plus and B4 Nonotubes with 4 mL.L-1 concentration O1 protikcalbor with1mL.L-1 concentration O2 with 2 mL.L-1, O3 optimus plus with 3 mL.L-1 and O4 optimus plus with 4 mL.L-1. The results showed that the protikcalbor with 3mL.L-1treatmnt was superiorinthe plant height (152.2 cm) chlorophyll content (33.57). Spadprotikcalbor with 4mL.L-1 treatmnt was superior in the number of leaves (13.47) compared with the contrel which gave the lowest rates for all the traits.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
