Glycine Max L

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.

The application of technologies to extend the postharvest life of mangosteen fruit was studied and compared to storage at 25 °C/70-75%R.H (25 °C control treatment). The fruits were packed in expanded polystyrene (EPS) trays (5 fruits/tray). Five treatments were carried out at 13 °C/ 90-95% RH: application of carnauba wax coating, lecithin + CMC (carboxymethyl cellulose) coating, 50 µm LDPE (low density polyethylene) film coating, 13 µm PVC (Polyvinyl chloride), and non-coated sample (13 °C control treatment). Physicochemical analyses were performed twice a week. A statistical design was completely randomized with 8 repetitions for each treatment plus the control treatment. The results were submitted to variance analysis, and the averages compared by the Tukey test at 5% probability. Among the quality parameters analyzed, more significant differences were observed for weight loss, texture, and peel moisture content. The results showed that the maximum storage period for mangosteen at 25 °C is two weeks; while storage at13 °C can guarantee the conservation of this fruit for 25 days. Therefore, the treatment at 13 °C/90-95% RH without the use of coatings and films was more effective and economical.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.

Field Emergence

Bean is a popular vegetable grown in most parts of Sri Lanka. Farmers and home gardeners purchase seeds in packeted form retail outlets. However, quality problems are frequently reported, especially on low field germination. Quality parameters namely, percentage germination, field emergence, seedling length, vigour index and chlorophyll fluorescence analysis were used to determine the effect of different storage environmental conditions on seed longevity of two bean varieties during a two-year storage period, 2016 to 2018. Seeds in triple-laminated packets stored in four contrasting conditions; low temperature storage conditions (Tem. 5oC, 65% RH); three geo-environmental conditions namely, Gannoruwa (mid country wet zone), Kundasale (mid country intermediate zone), and Mahailuppallama (low country dry zone) showed varied behavior in seed quality parameters respective of the variety. It was apparent that germination test alone does not represent the full potential of field emergence. Results of the present study revealed that when field emergence and vigour are also taken in to account, both varieties of bean seeds can be stored under ambient conditions at Gannoruwa, Kundasale or MahaIlluppallama for a maximum period of 12 months, without compromising the seed quality. The seeds stored under low temperature conditions (i.e. 5 °C), maintained the seed germination over 75% for a period of 24 months.

An investigation was undertaken with main objectives to know the effect of desiccants on seed quality parameters of crop seeds during storage and to assess the benefit cost ratio of storage method (economics) in wheat with initial seed moisture content of 12.3 %, was carried out at Department of Seed Science and Technology, College of Agriculture, UAS, Dharwad. Quantity of desiccants stored per kilogram of seed in wheat seeds is 0.37 kg for zeolite beads, one kg for silica gel, calcium carbonate and control without desiccant in airtight container. The experiment was laid out in Completely Randomized Design with four treatments and five replications. Seed stored with zeolite beads recorded the highest germination (88.8 %) which was on par with silica gel (87.2 %) at the end of storage period. Lower seed moisture and hundred seed weight was observed in the seeds stored with silica gel at the end of storage period. Higher shoot length, root length, seedling vigour-I and seedling dry weight was observed in seeds stored with zeolite beads which was on par with Silica gel at the end of storage period. compared to control. Therefore, it can be concluded that the zeolite beads can safely be used for seed drying without impairment in seed quality.
