In this study two different seed lots were taken first seed lot having higher germination percentage and second seed lot having lower germination percentage. Seeds were dry dressed with nanoparticles of silver and iron with different concentration and kept for storage. Seed lots revealed significant variation of the seed quality and storability due to nanoparticles treatments on soybean cv. DSb-21. High vigour seed lot recorded higher seed germination and seedling vigour index-I than the low vigour seed lot at the end of storage. The nanoparticles treatment FeNPs @500 ppm which recorded significantly higher seed germination (92.5%) and seedling vigour index-I (3127) than control at the beginning, maintained the trend till the end of 10 month of storage period. The rate of reduction in quality parameters was much higher in the low vigour seed lot. The seed treatment with nanoparticles reduced the rate of deterioration of seed in the storage.
The field experiment was carried out at Water and Land Use Management Institute (WALMI) Farm, University of Agricultural Sciences, Dharwad during 2015-16 and 2016-17 to study the effect of seed priming on growth and seed yield in kabuli chickpea varieties. The experiment was laid in split plot design with three replications constituting two kabuli chickpea varieties and nine seed priming treatments. The results of pooled data revealed that, kabuli chickpea variety BG1105(V1) recorded significantly higher values for all parameters over MNK-1 (V2) while, seed priming with Sprint (Mancozeb 50% + Carbendazim 25% WS) @ 2 g per kg of seed (T9) recorded significantly higher chlorophyll content (53.45 SPAD value/plant) at 75 DAS, plant height (48.01 cm/plant), secondary branches (23.38/plant), number of pods (44.73/plant), seed yield (33.97 g/plant and 16.59 q/ha) compared other treatments and control (T1) (44.07 SPAD value/plant, 42.34 cm/plant, 17.98/plant, 32.25/plant, 19.95 g/plant, 12.09 q/ha, respectively) at harvest.
The field experiment was carried out at WALMI Farm, University of Agricultural Sciences, Dharwad during 2015-16 and 2016-17 on organically maintained field to study the influence of soil application of organic manures and foliar spray of liquid biofertilizers on growth and seed yield of kabuli chickpea varieties. The experiment was laid in split plot design with three replications constituting two kabuli chickpea varieties and seven fertilizer treatments. The results revealed that, kabuli chickpea variety BG1105 (V1) recorded significantly higher values for seed yield and its yield attributes compared to MNK-1 (V2) while, application of 100 % organics equivalent to RDP (50 % FYM and 50 % vermicompost) in combination with either of foliar application with Panchagavya @ 3 % or Biodigester @ 10 % or cow urine spray @ 10 % at flowering and 15 days after flowering can be used for obtaining higher seed yield in Kabuli chickpea varieties.
to study the influence of seed grading and specific gravity separator on seed quality parameters of soybean var. DSb-21. Among the three sieve size used 3.75 mm recorded higher recovery (77.60%), seed germination (85.00%) and seedling vigour index (3293) followed by 4.00 mm (75.20%, 84.33% and 3179, respectively) and 4.80 mm (66.00%, 81.67% and 3016, respectively) over other sieves used under study, indicating that Seeds obtained from specific gravity separator after processing through seed grader from below recommended sieve size -3.75 mm processing equipment's have great impact upgrading the seed quality.
Seed coating especially film coating, is one such technique which has gained commercial importance owning to its practical utility as an effective delivery system as seed protectant and fortifying chemicals which maintain good germinability and vigour in field as well as laboratory viz.,strong seedlings grow faster than less vigorous ones, are more tolerant to adverse conditions in the seedbed and are better to resist diseases. Seeds of soybean cv. JS-335 were coated with polymer ((DISCO AG SP RED L-200), protectant (thiram and carboxin), bioagent (Mycorrhiza) and polymer untreated seeds as control. It was observed that, irrespective of the treatments, the seed quality parameters declined progressively with the increase in storage period (12 months). Under field conditions, higher vigour (2348) was noticed in seed treated with polymer (DISCO AG SP RED L-200) + Thiram + Quick roots **/ Mycorrhiza and lower vigour was seen inno polymer treatment or water + thiram. The field emergence (%) revealed that all the three polymer seed coating treatments were on par at 30 DAS (78.07 %, 77.19 % and 77.19 %) and 50 DAS (80.99 %, 80.11 % and 79.56 %) when compared to control treatment i.e., no polymer treatment or water + thiram at 30 DAS (71.68 %) and 50 DAS (71.30 %), respectively. Among the yield attributes, significant difference was observed in seed yield/plant with treatment polymer (DISCO AG SP RED L-200) + Thiram + Quick roots **/ mycorrhiza registering highest (22.20 g) yield, while the lowest (18.40 g) yield was observed in polymer untreated or water + thiram.
