Seed germination and seedling dry matter production of canola, barley and wheat as affected by seed-placed KCl and polymer-coated KCl

Seed-placed KCl often adversely affects seed germination and seedling growth because of the high salt index of the material. By coating KCl granules the adverse effect of the KCl can be reduced. Two greenhouse experiments with canola, barley and wheat, and one experiment in the field with barley were conducted to determine if normally adverse levels of seed-placed KCl fertilizer could be reduced when polymer-coated KCl is used. The results show that the number of germinated seeds and seedling dry matter were higher with the seed-placed coated KCl than the seed-placed regular non-coated KCl. Key words: KCl fertilizer, polymer-coated KCl, germination, seedling dry matter

Germinated Seeds

Seed germination and seedling characteristics of atrazine-susceptible and resistant wild turnip rape biotypes (Brassica campestris L.) were examined. Seeds of the susceptible biotype germinated earlier, and the germinated seeds grew faster and emerged earlier than seeds of the resistant biotype. Seedlings of the susceptible biotype emerged from greater planting depths than the resistant seedlings. Emerged susceptible seedlings were larger, with longer hypocotyls and greater cotyledon area, and produced more dry matter than the resistant biotype seedlings. Differences in water content of germinated seeds of the two biotypes were noted, with the susceptible biotypes consistently showing a higher water content. There was no significant difference in the respiration rate of the two biotypes at the early stage of seedling growth.

Germination Traits

Abstract Soil salinity represents a major constraint limiting crop production in arid and semi-arid countries. The effect of salinity induced by sodium chloride (NaCl) at five levels (0, 50, 100, 150 and 200 mM) was investigated on four germination traits and thirteen seedling growth characteristics in twenty cowpea [Vigna unguiculata (L.) Walp.] genotypes (ET11, KEB-CP004, KEB-CP006, KEB-CP009, KEB-CP 010, KEB-CP020, KEB-CP033, KEB-CP038, KEB-CP039, KEB-CP045, KEB-CP051, KEB-CP054, KEB-CP057, KEB-CP060, KEB-CP067, KEB-CP068, KEB-CP118, MTA22, NO74 and NO1036). The germination tests were carried out on Petri dishes in the laboratory while seedling growth experiments continued in plastic pots in the greenhouse, both setting up using a randomised complete block design with three replications. Genotypic responses were significant for all germination traits (p < 0.001). Germination percentage, germination rate index, and coefficient of velocity of germination were all decreased by salt stress. However, the mean germination time increased with increasing saline conditions. Significant differences were found between genotypes for most growth attributes. Growth rate (centimeter increased in height per week) decreased significantly with increasing salinity, starting at 100 mM NaCl (24.20% reduction, 2.66 cm / week) with maximum reduction (38.58%) corresponding to 2.16 cm/week observed at 200 mM NaCl, compared to control (3.51 cm/week growth rate). Also, significant decline in shoot weights, number of functional leaves and dry matter production were observed under salinity. Salinity also reduced water content in shoot and root and did not affect root weights. Under salinity, significant correlations were found between all germination variables (p < 0.001). Growth rate was significantly associated with ten out of the twelve other seedling growth traits. Also, the dry matter production under salinity was significantly associated with all other seedling growth characteristics with the exception of root water content. Given the effect of salt stress, cowpea genotypes, namely NO1036, KEB-CP004, KEB-CP038 and KEB-CP051, were the most tolerant while KEB-CP068 and ET11 were the most sensitive ones. The results confirm substantial genetic variation in salt stress tolerance among the studied genotypes. The most tolerant genotypes should be further explored in genetic improvement programs and should be promoted for culture in regions affected by salinity.
