    Studies on impact of natural ageing and seed priming on seed quality in Indian mustard [Brassica juncea (L.) czern. & coss
    (CCSHAU, 2018) Pradeep Singh; Punia, R.C.
    The present study entitled “Studies on impact of natural ageing and seed priming on seed quality in Indian mustard. [Brassica juncea (L.) Czern. & Coss.]” was carried out in the Department of Seed Science and Technology at CCS Haryana Agricultural University, Hisar (Haryana) during the year 2015-16 and 2016-17. The experiments was laid out in factorial Complete Randomized Design (CRD) and Randomized Block Design (RBD) for laboratory and field parameters, respectively on three varieties of Indian mustard viz., RH 30, RH 9304 and RH 0406 with three seed lots of each variety. The present investigation was carried out in two different experiments to meet out the objectives of study. In the first experiment, three lots of different Indian mustard were studied for various seed physiological parameters viz., standard germination, seedling length, seedling dry weight, vigour index-I & II, viability test (Tz %), and accelerated ageing. All physiological parameters were decreased significantly with the advancement of natural ageing of seeds. All the biochemical parameters viz., peroxidase (POX), superoxide dismutase (SOD), dehydrogenase enzyme activity decreased significantly with passage of time, whereas, electrical conductivity of seeds leachates increased with the advancement of time. The field parameters viz., seedling emergence index and seedling establishment were also decreased significantly with the advancement of time whereas, mean emergence time increased with the passage of time. In the second experiment, six seed priming treatments viz., T0: Control, T1: hydro-priming followed by dry dressing with carbendazim (2g/kg), T2: Hydration with GA3 (50 ppm), T3: Hydration with KNO3 (0.5%), T4: Hydration with KH2PO4 (0.5%), T5: Biofertilizer (Azotobacter) were analyzed to identify the suitable priming treatment. Among various priming treatments „T2‟- hydration with GA3 @ 50 ppm followed by „T6‟-Biofertilizer performed best to enhance all the seed vigour and viability characteristics and to lower down the electrical conductivity of naturally aged seed lots of Indian mustard seeds. The seed quality improvement through seed priming was noticed more in marginal seed lot i.e. one year old seed lot. Among the different varieties, maximum enhancement was observed in RH-30 followed by RH-9304 whereas, minimum enhancement was observed in variety RH-0406 during the periodof study. In conclusion, the present study revealed that Indian mustard seed lose its viability and vigour with the advancement of storage time and seed priming with GA3 @ 50 ppm and Biofertilizer (Azotobacter) can be used as an effective tool to enhance vigour and viability of seed.

    Effect of integrated nutrient management on seed yield, quality and its storability in Field Pea (Pisum sativum L.)
    (CCSHAU, 2018) Pandey, Vineeta; Dahiya, O.S.
    The present research was carried out at the research farm and laboratories of Department of Seed Science & Technology, CCS, Haryana Agricultural University, Hisar to evaluate the effect of integrated nutrient management on seed yield, quality and its storability in field pea (Pisum sativum L.). The material comprised of a variety “HFP-529” which was grown in the research farm of Department of Seed Science & Technology with twenty three treatment combinations of organic manures, inorganic fertilizers and biofertilizers. All the treatments were assessed for different seed yield, quality and storability parameters. Among the treatments, Rhizobium+PSB+100% recommended dose of nitrogen exhibited better performance in terms of yield and its attributes as compared to control. It was observed that application of Rhizobium+PSB+100% nitrogen followed by Rhizobium+PSB+75% nitrogen had maximum vigour potential in terms of test weight, seed density, standard germination, seedling length, seedling dry weight, vigour index, lower electrical conductivity as compared to control. The higher antioxidant enzyme activities (CAT, POD, SOD and dehydrogenase) were recorded in the treatment combination of Rhizobium+PSB+100% nitrogen followed by Rhizobium+PSB+75% nitrogen in comparison to rest of treatments. Nutrient combination of Rhizobium+PSB+100% nitrogen showed maximum speed of emergence, seedling establishment and minimum mean emergence time. Seeds of all the treatment combinations were stored for fifteen months in plastic bags and seed quality was evaluated after five, ten and fifteen month’s interval. It was noticed that seed vigour and quality was negatively affected during storage. Though all the treatments showed decline in vigour but less decline was recorded in the treatment Rhizobium+PSB+100% nitrogen as compared to other treatments after fifteen months of storage. After estimating antioxidant enzyme activities it was found that there activities were declined during ambient storage, however the maximum activity after fifteen months of storage was recorded in the treatment Rhizobium+PSB+100% nitrogen. The freshly harvested seeds of all the treatments were subjected to artificial ageing at 40±1 °C for 72 h and were again assessed for seed quality and antioxidant enzyme activities. After artificial ageing it was noticed that treatment combination of Rhizobium+PSB+100% nitrogen followed by Rhizobium+PSB+75% nitrogen showed better performance in all the seed quality parameters and maximum antioxidant enzyme activities in comparison to other treatments.

    Conventional & chemical approach for varietal identification and seed vigour studies in Indian mustard. [Brassica juncea (L.)Czern.& Coss.]
    (CCSHAU, 2017) Rai, Himanshu; Dahiya, O.S.
    The present study entitled “Conventional & chemical approach for varietal identification and seed vigour studies in Indian mustard. [Brassica juncea (L.) Czern. & Coss.]” was conducted on 20 Indian mustard varieties which were grown during Rabi 2014-2015 and 2015-16 to characterize them on the basis of morphological characters and chemical methods and to evaluate their seed vigour. The study revealed that morphological characters viz., leaf hairness, leaf colour, leaf lobes, leaf number of lobes, time of flowering (50%), leaf length, leaf width, flower colour of petals, plant main shoot length, plant height, siliqua texture, siliqua length, siliqua number on main shoot, number of seed per siliqua, maturity period, seed colour and test weight were the most important diagnostic characters which provide an excellent system of variety identification in Indian mustard in field condition. Based on chemical tests, Phenol test grouped varieties into three distinct groups viz., dark reddish brown (12varieties), dark grey (6 varieties) and dark red (2 varieties).The modified phenol test grouped these varieties into further sub groups viz., dark brown (6 varieties), brown (7 varieties), reddish brown (4 varieties) and strong brown (3 varieties). Potassium hydroxide test (KOH) grouped varieties into dark brown (6 varieties), brown colour (5 varieties) and light brown (9 varieties). These tests clearly differentiated one group variety from another groups on the basis of seed coat colour. Based on peroxidase test the varieties showed high (9 varieties), medium (8 varieties) and low (3 varieties) activity of peroxidase enzyme while 2,4-D auxin test revealed that the varieties were tolerant (4 varieties), susceptible (8 varieties) and highly susceptible (8 varieties). Among the 20 varieties RH30, Kranti, Varuna, NRCDR601 and RH819 showed superiority for almost all viability and vigour parameters while the varieties NRCHB101, RB50, RH0119, RH0406 and RH8113 proved to be inferior. All the seed quality parameters were found to have significant and positive correlation with standard germination and seedling establishment whereas negative and significant association with electrical conductivity and mean emergence time. Dehydrogenase activity, tetrazolium test and electrical conductivity were found to be most efficient for prediction of standard germination while dehydrogenase activity, standard germination, electrical conductivity test and accelerated ageing test were found to be most reliable tests to predict seedling establishment in the field.

    The present investigation was carried out at the Department of Seed Science and Technology. CCS Haryana Agricultural University, Hisar to assess the effect of integrated nutrient management on seed yield, quality and storability in fenugreek. The material comprised of a single variety “Hisar Suvarna” which was grown in the research farm of Department of Vegetable Science with seventeen treatment combinations of organic manures, inorganic fertilizers and biofertilizers. All the treatment combinations were evaluated for different seed yield, quality, and storability parameters. Among the treatments, Rhizobium+PSB+75% recommended dose of nitrogen showed better performance in terms of yield and its components as compared to control. It was found that seeds with the application of Rhizobium+PSB+75% nitrogen followed by Rhizobium+100% nitrogen had higher vigour potential in terms of test weight, seed density, germination percent, seedling length, seedling dry weight, lower electrical conductivity as compared to control. The treatment Rhizobium+PSB+75% nitrogen followed by PSB+100% nitrogen showed higher antioxidant enzyme activities (CAT, POD, SOD) in comparison to other treatment combinations. Higher speed of emergence, seedling establishment and lower mean emergence time was observed in nutrient combination of PSB+100% nitrogen. Seeds of all the treatment combinations were stored for eighteen months in plastic containers and seed quality was evaluated after six, twelve and eighteen months interval. It was observed that storage affected seed vigour and seed quality adversely. Though all the treatments showed decrease in vigour but less decrease was found in the treatment Rhizobium+PSB+75% nitrogen in comparison to other treatments after eighteen months of storage. After evaluating antioxidant enzyme activities it was observed that activities of these enzymes decreased during ambient storage, however the highest activity after eighteen months of storage was observed in the treatment PSB+100% nitrogen. The freshly harvested seeds of all the treatment combinations were subjected to artificial ageing at 40±1 °C for 72 h and were again evualted for seed quality and antioxidant enzyme activities. After artificial ageing it was observed that the treatment combination of Rhizobium+PSB+75% nitrogen followed by PSB+100% nitrogen showed better performance in all the seed quality parameters and higher antioxidant enzyme activities as compared to rest of treatments.

    Effect of integrated crop management on seed yield, quality and storability in Mungbean (Vigna radiata L. Wilczek)
    (CCSHAU, 2017) Jitender; Punia, R.C.
    The study was planned to assess the effect of integrated crop management on seed yield, quality and storability in mungbean. Sixteen treatment combinations were evaluated for different seed yield, quality, and storability parameters. Significant mean squares values showed the wide variability among the treatments and both seasons for all the parameters studied. Among the treatments, RDF+RWM+RPM followed by RDF+Biomix had the top rank for almost all the seed yield, quality and storability except electrical conductivity and mean emergence time which showed the lower value indicating their superiority in both the season(summer and kharif 2015). On the contrary, control found to be inferior for most of the seed yield, quality and storability parameters except days to maturity. Among the seasons, seed yield and its components were better in kharif season as compared to summer season. Seed produced in summer season showed superiority over kharif for seed quality and storability parameters. Seed yield and plant height were found significantly and positively correlated with its components. Standard germination and seedling establishment were found significantly and positively correlated with all the seed quality parameters except electrical conductivity and mean emergence time in both the seasons. Electrical conductivity was found significantly and negatively associated with all parameters studied in lab and field. Therefore, it is concluded that pH exudate, electrical conductivity test and dehydrogenase activity test can be used as a quick reliable predictor of standard germination and seedling establishment in mungbean. Higher seed yield was obtained in kharif season but summer season could be considered better option for the production of basic seed due to its superiority for almost all the seed quality parameters.

    Evaluation of seed vigour parameters for heat tolerance in bread wheat
    (CCSHAU, 2014) Arun Kumar; Dahiya, O.S.
    Wheat (Triticum aestivum L.) is a widely adapted crop. It is grown from temperate, irrigated to dry and high-rain-fall areas and from warm, humid to dry, cold environments. The genetic purity, physical purity, viability, vigour and uniform seed size are the most important parameters to determine the quality of seed. High seed germination and vigour are pre- requisites for the success of stand establishment of crop plants. Generally stress (moisture/heat) has deleterious effect on germination and vigour of crop.The present investigation was carried out at the department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar. The material comprised of six each heat tolerant and susceptible varieties which were sown on two date i.e. normal (19th, 20th November) and late sown (19th, 20th December). The observations were recorded at grain filling stage (heading to maturity). Heat tolerant varieties had performed better at different stages of seed development in comparison to susceptible. Heat tolerant varieties were found significantly higher for seed weight, seed moisture content, germination, seedling length, vigour index-I & II, seedling dry weight and than susceptible varieties under normal and late sowing condition in both the year. Heat tolerant varieties were recorded significantly lower for days to heading, physiological and harvestable maturity. It means heat tolerant varieties mature earlier than susceptible. Commonly varieties had performed better for all characters studied in normal than late sowing at all stages of seed development. Heat tolerant varieties recorded higher for membrane Thermostability and lower for chlorophyll fluorescence. This might be effect of heat stress during seed development. Both vigour index-I and II were significantly and negatively correlated with maximum, minimum and difference of temperature but positively with sunshine hour and relative humidity in both the years of data recording. It means that as optimum temperature for cultivation of wheat is increasing then vigour of the seed will be decreases. For normal as well as late sown heat tolerant varieties having more DHA, peroxidase, catalase and superoxide dismutase activity at all stages than heat susceptible. All stress enzyme activity was higher in late than normal sowing which was in concurrence with high temperature during seed development. Number of grains per spike (average of five plants), number of grains per spike and grain yield per plant was higher for normal sown than late sown in both the year. Varieties have performed better in second year than in first year. Heat tolerant has performed better than susceptible for almost all agronomic traits. Based on both the tests it can infer that there was better relative storability of the variety for normal than late sowing over the years at all stages of storage.
