“…Lower yield and lower mean value for yield attributes were observed in control treatment. These results are in agreement with Manjunath and Dhanoji, (2011) who stated that treating wheat seeds with 0.25% CaCl 2 or 2.5% KCl increased the grain yield compare to control. The increase in grain yield with pre sowing treatments was due to the expansion of leaves, which resulted in higher photosynthesis, assimilation and ultimately higher production of total dry matter.…”

“…Pre-sowing hardening technique is a repeated soaking and control seed hydration in solution containing organic or inorganic solutes followed by redrying that allows pre-germinative metabolic activities but prevent radical emergence (Basra et al, 2005). The hardening treatment proved to be better for vigor enhancement than the traditional soaking (Manjunath and Dhanoji, 2011). Seed hardening treatments enhances seeds vigor by protecting structure of the plasma membrane against injury during stress environment (Bewley and Black, 1994;JunMin et al, 2000).…”

Exploring ways to improve stand establishment and crop productivity under abiotic stresses like drought is important. Two years experiments were conducted at University of Agriculture, Peshawar-Pakistan to examine the efficacy of six pre-sowing seed hardening agents. Seeds of wheat cultivar Uqab-2000 were hardened in six different chemicals of various concentration viz; PEG-8000 (10%), CaCl 2 (4%), KNO 3 , (3%), Mannital (4%), NaCl (5%), Na 2 SO 4 (2%) along with water soaking and dry seeds as control for 24 hours and drying back to original moisture content at room temperature. The soaking and drying of seeds was repeated twice for 12 hours. The results showed that pre-sowing hardening of seed with PEG-8000, CaCl 2 and KNO 3 gave higher germination, decreased days to 50% germination, increased shoot length, root length, seedling fresh and dry weight in laboratory experiment as compared with other hardening and control treatment. Under field conditions, maximum plant height (93.53cm), spikelet's spike -1 (17.16), grains spike -1 (50.82), 1000 grain weight (39.97 g), grain yield (3.43 tha -1 ) and maximum harvest index (32.5%) were observed in PEG-8000 hardened seed than control treatment (2.82 tha -1). Seed hardened in PEG-8000, CaCl 2 and KNO 3 gave 30% increase in grain yield as compared to Mannital, NaCl and Na 2 SO 4 which gave 15% increase in grain yield over control treatment.

“…The reduction in plant height due to growth retardants is mainly seems to have released the apical dominance and diversion of the plant metabolites from vertical growth to horizontal growth and thereby more number of branches per plant. These results are in conformity with the findings of Avijit Sen (1983) in wheat, Arjun Sharma et al (2003) in pigeon pea, Manjunath and Dhanoji (2011) and Sujatha (2014) in chickpea.…”

Background: Pre-sowing seed priming and foliar spraying with Plant Growth Regulators is an easy, low cost and low risk technique and also an alternative approach recently used to mitigate the effect of abiotic stresses in agricultural production.Methods: Seeds of Mung bean var. GAM-5 were primed and also foliar spraying at 30 DAS with CaCl2 2% and 1%, Cycocel 500, 1000 ppm, NAA 25, 50 ppm during summer season of 2015-16 and 2016-17.Result: The results indicated a significant improvement in morpho-physiological traits, growth parameters, biochemical constituents and thereby yield due to the application of PGRs. Seed priming with 2% CaCl2 followed by 1% foliar spraying at 30 DAS (T11) significantly improved most of morpho-physiological parameters viz., plant height, number of branches per plant, days to 50% flowering, maturity, leaf area, chlorophyll content, seed protein content, number of pods per plant, number of seeds per pod, test weight, pod length, yield per plant, yield per hectare, harvest index in green gram followed by the seed priming with Cycocel 1000 ppm followed by foliar spraying at 30 DAS (T13) and seed priming with NAA 50 ppm followed by foliar spraying at 30 DAS (T15). The treatment T11 was more efficient.

“…However, it remained at par with the treatments Cycocel 1000 mg/L (T 3 ) (89.33% and 8.33%, respectively). The probable reason for early and higher germination of soaked seeds may be due to completion of pre-germinative metabolic activities making the seed ready for radical protrusion in mung bean reported by Manjunatha and Dhanoji (2011) and Sujatha (2014), in chickpea. This might be due to a number of physio-chemical changes occurred in seed that modify the protoplasmic characters and thereby increased physiological activity of embryo and associated structures development for efficient seedling germination.…”

Background: Green gram is a drought resistant crop requires low inputs. The productivity of mung bean is very low. Initial germination, growth and vigour are some major reasons of low productivity. The present investigation was carried out to study the effect of seed hardening on morpho-physiological and seedling quality characters in green gram. Methods: The green gram var. GAM-5 was imposed with seed hardening treatments viz., 2% CaCl2, 500 ppm Cycocel, 1000 ppm Cycocel, 25 ppm NAA, 50 ppm NAA, water soaked control and absolute control. The treated seeds along with control were evaluated for their seedling quality characters under laboratory conditions. Result: The study reported that seeds hardened with CaCl2 @ 2% recorded higher germination per cent, root, shoot and seedling length, fresh weight, turgor weight, dry weight and seed vigour index I and II. Seed hardened with 50 ppm NAA reported higher root dry weight and root to shoot ratio on dry weight basis while Cycocel 1000 ppm treatment recorded higher root to shoot ratio on length basis. The treatments CaCl2 2% followed by Cycocel 1000 ppm were found to be superior as compared to other treatments and control on the basis of lab studies.
