Abstract
In determining the growth, yield and quality of groundnut, the role of boron is much pronounced. Restricted availability of this nutrient in coastal saline soil greatly impairs the yield of groundnut. Therefore, a field experiment was conducted to find out the effect of different levels and source of boron fertilizers on the growth and yield of groundnut in coastal saline soil. The experiment was carried out in a farmer’s field at Singarakuppam coastal village near Chidambaram, Cuddalore district of Tamilnadu during June –Aug, 2020. The texture of the soil was sandy and taxonomically classified as Typic usticpsaments with pH-8.23, EC- 4.14 dS m-1 and represented low status of organic carbon (2.32 g kg-1). The soil had low alkaline KMnO4-N (139.50 kg ha-1), low in Olsen- P (9.57 kg ha-1), medium in NH4OAc-K (164.78 kg ha-1) and available B (Hot water-B) content (0.23 mg kg-1). The fifteen treatments consisted of five levels of boron viz., 0, 0.5, 1.0, 1.5 and 2.0 kg B ha-1 as factor-L and three different sources of boron fertilizers like S1– Borax; S2– Solubor and S3– Boro-Humate as factor-S. The experiment was laid out in a Factorial Randomized Block Design (FRBD) with three replications, using groundnut variety VRI 2 as test crop. The results revealed that the combined application of B @ 1.5 kg ha-1 through Boro-Humate significantly increased the growth, yield characters and yield of groundnut.
