A laboratory experiment was conducted to know the effect seed treatment with nano insecticides on seed quality of pigeonpea (Cajanus cajan (L.) Millsp.) cv. TS3R. This study was conducted to evaluate the effect of macro and nano insecticides on seed germination and vigour of Pigeonpea. Different recommended seed treatment insecticides viz, malathion, fenvalerate, emamectine benzoate, thiodicarb, sweet flag and neem seed kernel powder insecticides were synthesized to nano form using high energy planetary ball mill. The Pigeonpea seed were treated with different nano insecticides i.e., 10-90 per cent reduction in actual dosage. Among the different treatments studied, seed treated with nano malathion 50 per cent lesser than normal dosage, fenvalerate 60 per cent lesser, thiodicarb 10 per cent lesser, emamectine benzoate 30 per cent lesser, sweetflag 70 per cent lesser, neem seed kernel powder 40 per cent lesser than actual recommended dosage gave significantly higher seed germination (98.0, 98.67, 98.67, 97.0, 99.0 and 98.67 percent) ,less number of abnormal seedlings (1.0, 0.33, 1.0, 1.0, 1.0 and 0.33 per cent) , shoot length (10.13, 9.00, 11.47, 9.50, 10.90 and 10.87 cm), root length (12.56, 12.93, 12.83, 12.60 11.50 and 13.00 cm), seedling dry weight (85.73, 87.40, 88.47, 87.70, 88.60 and 88.27 g) and seedling vigour index (2223, 2164, 2397, 2143, 2217 and 2354) as compared to untreated seeds and macro insecticides. Therefore, it is very clear that nano based insecticides has a significant (0.1 %) impact on the seed quality improvement.

“…Similarly, the abnormal seedlings (Ab S) and dead seeds (DS) were recorded as per ISTA (ISTA, 2013). While, the mean germination time (MGT) was computed by adopting the formula suggested by (Azimi et al, 2013). Whereas, the germination rate index (GRI) was determined as per the procedure prescribed by Mudaris (1998), peak value of germination (PVG) by (Gairola et al, 2011), shoot length (SL), root length (RL), seedling dry weight (SDW), seedling vigour index (SVI) by Abdul-Baki and Anderson (1973), insect egg and seed damage by (Tamiru et al, 2016), percent weight loss by Harris and Lindblad (1978), dehydrogenase enzyme acticity (DH) by Kittock and Law (1968)., alpha amylase enzyme activity by Simpson and Naylor (1962) and electrical conductivity (EC) by (Milosevic et al, 2010) were recorded.…”

to study the influence of gamma irradiation and seed treatment chemicals on seed longevity of bengal gram (Cicer arietinum L.) and black gram (Vigna mungo L.). The experiment consisted of nine treatments with different dosage of gamma irradiation and seed treatment chemicals. Among the different treatments imposed, significantly higher seed germination (87.0 and 83.8 %), germination rate index (4684 and 3946), peak value of germination (23.5 and 20.0), seedling vigour index (2069 and 1755), dehydrogenase enzyme activity (1.816 and 1.576 OD value) and alpha amylase enzyme activity (23.5 and 18.8 mm) with lowest abnormal seedling (8.3 and 9.0 %) and mean germination time (2.10 and 2.34) were recorded even after nine months storage, respectively in bengal gram and black gram, respectively by treating the seeds with the combination of malathion + thiram each @ 2.0 g / kg of seed as compared to all other treatments and control. The above treatment was also effective in control of cent per cent insect eggs there by without any seed damage and consequently no weight loss compared to control with 23.00, 12.92 and 7.76 per cent insect egg, seed damage and weight loss, respectively in bengal gram. But in case of black gram the seed infestation did not take place in any of the treatments including control. Further, exposing the seeds to the gamma irradiation (T 2 to T 6 ) showed a significant reduction in all above seed quality parameters with an increase in gamma irradiation dosage. While, the seed quality parameters such as, abnormal seedlings, dead seeds, mean germination time and electrical conductivity increased with the increase in dosage of gamma irradiation. However, among all the gamma irradiation treatments imposed, the highest dosage of gamma irradiation (T6-100 Gy) recorded the least seed damage (1.46 %) and weight loss (0.02%) only.

The aid of beneficial microbes, which is a well-accepted strategy, may improve plant salt tolerance. However, the mechanisms that underpin it are unclear. In this study, seedling experiments were carried out to assess the effect of Bradyrhizobium and Enterobacter on the germination, growth, nonenzymatic and enzymatic content in soybean (Glycine max L.) under salt stress. Water was sprayed on the seeds as a control, and with 75 mM, 150 mM NaCl as salt stress. The findings demonstrate that salt stress (75, 150 mM) caused a significant decrease in germination, morphological criteria, and membrane stability index (MSI) when compared to control seeds but increased lipid peroxidation (MDA), electrolyte leakage (EL), osmotic pressure, proline, citric acid, sugar content, antioxidant enzymes. Furthermore, endophytic Bradyrhizobium and Enterobacter inoculation resulted in a significant rise in all of the above metrics.; however, these treatments resulted in significant reductions in ROS, EL, and MDA in stressed plants. Finally, the findings showed that combining Bradyrhizobium and Enterobacter was the most efficient in reducing the harmful effects of salt on soybean plants by boosting antioxidant up-regulation and lowering membrane leakage and ROS.
