The boron (B) concentration surpasses the plant need in arid and semi-arid regions of the world, resulting in phyto-toxicity. Salicylic acid (SA) is an endogenous signaling molecule responsible for stress tolerance in plants and is a potential candidate for ameliorating B toxicity. In this study, the effects of seed priming with SA (0, 50, 100 and 150 µM for 12 h) on the growth, pigmentation and mineral concentrations of maize (Zea mays L.) grown under B toxicity were investigated. One-week old seedlings were subjected to soil spiked with B (0, 15 and 30 mg kg−1 soil) as boric acid. Elevating concentrations of B reduced the root and shoot length, but these losses were significantly restored in plants raised from seeds primed with 100 µM of SA. The B application decreased the root and shoot fresh/dry biomasses significantly at 30 mg kg−1 soil. The chlorophyll and carotenoid contents decreased with increasing levels of B, while the contents of anthocyanin, H2O2, ascorbic acid (ASA) and glycinebetaine (GB) were enhanced. The root K and Ca contents were significantly increased, while a reduction in the shoot K contents was recorded. The nitrate concentration was significantly higher in the shoot as compared to the root under applied B toxic regimes. However, all of these B toxicity effects were diminished with 100 µM SA applications. The current study outcomes suggested that the exogenously applied SA modulates the response of plants grown under B toxic conditions, and hence could be used as a plant growth regulator to stimulate plant growth and enhance mineral nutrient uptake under B-stressed conditions.

The research work was carried out at the Seed Laboratory of Agronomy Department of Bangladesh Agricultural University, Mymensingh, Bangladesh during the period from March to November in 2008 to find out the effect of different osmopriming techniques on seedling emergence of maize. Seventeen osmopriming techniques viz., T1 = 1% Na2SO4, T2 = 3% Na2SO4, T3 = 5% Na2SO4, T4 = 1% K2HPO4, T5 = 3% K2HPO4, T6 = 5% K2HPO4, T7 = 1% ZnSO4, T8 = 3% ZnSO4, T9 = 5% ZnSO4, T10 = 1% Ca(H2PO4)2, T11 = 3% Ca(H2PO4)2, T12 = 5% Ca(H2PO4)2, T13 = 1% H2O2, T14 = 3% H2O2, T15 = 5% H2O2, T16 = Hydropriming, T17 = Non-priming (control) were used as experimental variables. Different osmopriming methods on seedling emergence performance of maize was evaluated at two moisture levels viz., 30 and 60% moisture of saturated sand in the experiment. Germination percentage, germination index and mean germination time were influenced significantly by osmopriming methods. Seed priming with 3% ZnSO4 showed the highest seedling emergence which was followed by 1% H2O2 and 3% Ca (H2PO4)2. DOI: http://dx.doi.org/10.3329/bjar.v39i3.21986 Bangladesh J. Agril.

Hybrid Maize

Maize (Zea mays L.) is one of the most versatile crop grown throughout the tropical as well as temperate regions of the world. On the other hand, the lathyrus or grass pea or chickling pea is also called ‘khesari’ and is a very hardy crop that thrives well under adverse climatic conditions. It can fix biological nitrogen in their roots through symbiotic relationship with Rhizobium leguminoseram. The field experiment was conducted on seed priming of hybrid maize and lathyrus at Central Research Farm, BCKV, Nadia under new alluvial zone of West Bengal, India in Randomized Complete Block Design (RCBD) with 3 replications during kharif season of 2016 and 2017 and rabi season of 2016-17 and 2017-18. Experimental results reveal that seed priming methods significantly influenced the germination, growth parameters, yield attributes and yield of hybrid maize-lathyrus grown in sequence under rainfed situation. Seed priming with ZnSO4 @ 0.5% for 12 hours recorded the highest number of grains per cob (319.9) and highest plant height (262.10 cm) at harvest of hybrid maize. Grain yield and stover yield of hybrid maize showed positive and highly significant (P = 0.01) with each other (r = 0.945). The maximum number of pods per plant (50.28) was observed in seed priming with ZnSO4 @ 0.5% for 12 hours and was statistically at par with seed priming with KNO3 @ 0.5% for 12 hours (48.33) in case of lathyrus. Number of pods/ plants showed positive and highly significant (P = 0.01) correlation with grain yield (r = 0.986) of lathyrus. On the basis of pooled values of 2 years of experimentation, seed priming with ZnSO4 @ 0.5% for 12 hours could be recommended due to higher yield (7.94 t ha-1 of kharif hybrid maize and 1682 kg ha-1 of lathyrus) and higher net return (Rs.69,904/-ha-1 for maize, Rs.40,327/- ha-1 for lathyrus) as well as highest B:C ratio (2.74 of kharif hybrid maize and 2.94 of lathyrus) for maize-lathyrus in sequence under rainfed situation.
