Description Six independent experiments were conducted on sunflower during 2011 at CCS Haryana
Agricultural University, Hisar, India to study ''Response of Boron applications to sunflower
(Helianthus annuus L.) under saline conditions. The experiment-1 entitled “Response of Boron (B)
application to sunflower under Cl-dominated salinity” with four salinity levels (Control, 4, 8 and 12
dSm-1) and five Boron levels (Control, 1, 3, 6, 12 ppm), experiment-2 entitled “Response of B
application to sunflower under SO4
2- dominated salinity” with four salinity levels (Control, 4, 8 and 12
dSm-1) and five Boron levels (Control, 1, 3, 6, 12 ppm), experiment-3 entitled “Performance of
sunflower crop under Cl-dominated salinity” with four salinity level (Control, 4, 8 and 12 dSm-1) and
four genotypes (HSFH-848 F2, 91A x R17, 91A x HRHA53 and Hybrid Jawalamukhi), experiment-4
entitled “Performance of sunflower crop under SO4
2-dominated salinity” with four salinity level
(Control, 4, 8 and 12 dSm-1) and four genotypes (HSFH-848 F2, 91A x R17, 91A x HRHA53 and
Hybrid Jawalamukhi), experiment-5 entitled "Retention and movement of Boron under Cl-dominated
saline soils as affected by leaching levels" with five leaching level (200, 250, 300, 350 and 400 mm)
by maintaining soil salinity 8 dSm-1 and experiment-6 entitled "Retention and movement of Boron
under SO4
2- dominated saline soils as affected by leaching levels" with five leaching level (200, 250,
300, 350 and 400 mm) by maintaining soil salinity 8 dSm-1 were laid out in CRD with three
replications in Pot (Experiment No.1to 4) and laboratory (Experiments 5 and 6). Salinity was created
by pot experiments Na+1, Ca+2, Mg+2, Cl-1 and SO4
-2 salt in different quantity for different type of
salinity. Boric acid was for preparing Boron levels.
Germination of sunflower genotypes declined as salinity and boron levels were increased
under both type of salinity. Seed yield, oil content and protein content also decreased with increase in
salinity and boron levels. Boron concentration in stalk and seed was lower under saline conditions but
its concentration was increased with boron levels. Ion concentrations were higher at higher levels of
salinity and Na+, SO4 and Cl concentration in seed increased with B level and parallel the concentration
of Ca and Mg was decreased in both type of salinity. Hybrid Jawalamukhi recorded the maximum
germination percentage, seed yield, oil content and protein content in both types and all levels of
salinity. Hybrid Jamalamukhi seed maintain higher Ca+2, Mg+2 and SO4
-2, and minimum content of
Na+1 and Cl-1 to withstand against both types of salinity.
