Effect of hydro and osmo priming on yield and yield components of Chickpea (Cicer arietinum L.)

Abstract

A field study was conducted at Debre Zeit Agricultural Research center station under rain fed condition with the objectives to determine the effect of seed priming for improving chickpea variety productivity and to determine the effectiveness of seed priming treatment and variety on stand establishment. The experimental factors were laid out in RCBD with three replications. The study indicated that all the phenological and growth traits significantly differed as a result of priming treatment and variety. With respect to yield and yield related traits, only seed yield kgha -1 , harvest index (%), seeds plant -1 and seeds pod -1 were significantly affected by the main effect. While, the rest of yield related traits responded differently due to variety alone. However, all variables studied in the field were not significantly affected by the interactions of the main effects. Improvement made due to main effect hydro and osmopriming was statistically similar for all phenological traits; seeds plant -1 and seeds pod -1 was considerably improved as a result of osmopriming than hydropriming. However, plant height, stand count at emergence and at harvest, seed yield kg ha -1 were substantially increased by 7, 10, 12 and 15%, respectively as a result of water priming over the control. Therefore, from present study, it can be concluded that hydropriming can step-up economical benefit of chickpea growing farmers.

Standardization of Hydropriming Duration and its Effect on Physiological Parameters of Spinach (Spinacea oleracea L.)

“…The possible reason for enhanced seed germination and vigour at 24 hours of seed hydro-priming might be due to completion of pre-germinative metabolic processes i.e., activation and synthesis of a number of enzymes and nucleic acids repair and build up, ATP synthesis and the cytoplasmic membrane repair in hydro-primed seed a head start over the non-primed seeds making ready for radical protrusion (Varier et al, 2010) and also during priming, several processes including treated seeds start to develop (Fig 2b). These results are in conformity with Krishnakumar et al, (2008) in sugar beet, Tiwari et al, (2014) in amaranthus, Mohsen et al, (2013), Kamithi et al, (2016), Kaur et al, (2003), Kazem et al, (2012, Abebe (2014) and Rashid et al(2004) in spinach.…”

Osmo-Priming with Seaweed Extracts Enhances Yield of Salt-Stressed Tomato Plants

“…Osmo-priming activates different mechanisms of stress tolerance (i.e., improved antioxidant capacity, activation of signaling molecules, abscisic acid production) making the plant prone to better cope with the subsequent stress, thus maximizing plants productivity performances and survival [26]. Osmo-priming may also anticipate flower setting and shorten the time to harvest so to avoid plants exposure to salt build-up in the root zone [27][28][29]. SWE formulations generally contain high concentrations of organic and inorganic osmolytes that, when delivered via irrigation, may be partially absorbed by the plant and/or may induce a moderate and transient osmotic stress [13,20].…”
