In recent years, the application of magnetism in agriculture has been paid more and more attention to, especially in the field of its treatment on the seed germination and physiological indexes of seedlings grown out of them. In this experiment, the radish (Raphanus sativus L.) seeds of two cultivars ‘Carmen’ and ‘Szkarłatna z Białym Końcem’ were treated by 20 mT low frequency magnetic field (LFMF) for 10, 30 and 60 minutes, respectively. The MF was generated from a Viofor JPS Delux - a patented device adopted from the routine medical magnetic therapy. By measuring their seed germination rate (energy), seedling length and fresh weight, it was proved that LFMF improved the seed quality of both radish cultivars and the best results were received for the longest exposing time. The received that way results were similar as reported for priming of radish seeds. The developed treatment has a great potential in replacing traditional seed priming methods. However, for its commercial use, for selected crops and cultivars, further research is still needed.

Background: Paspalum scorbiculatum is an annual crop and has superior nutritional properties including high micronutrients, dietary fiber content and gluten free. It has low glycemic index (GI) carbohydrate diets help in prevention of Obesity, Diabeties and Cardiovascular diseases, etc. The current study was aimed to find out the suitable pre- sowing seed treatments for Kodo millet. Methods: During the Kharif season 2019- 2020 total of 12 pre- sowing seed treatments were subjected with Botanicals, Magnetic and Electric fields, Thermal (Hot water) treatments and to fix the best treatment based on Seed Quality and Morphological traits of treated seeds. Morphological traits play an major role in crop growth and development where as, the present investigation was carried out with farmer’s variety in field (RBD) design in 3 replications and laboratory (CRD) design in 4 replications in order to “Standardization of different pre- sowing seed treatments on growth, yield and yield attributing traits of Kodo millet (Paspalum scorbiculatum). Seeds were subjected to various pre- sowing seed treatments viz. (T0) control, exposure to Magnetic field at 100 mT, 200 mT, 400 mT for 15,30 and 45 min; exposure to Electric field at 50 mA, 100 mA, 150 mA for 5,10, 15 min. Treatment with botanicals cow dung (5 gm) and Datura leaf extract (2.5 ml) for 12 hrs; Thermal hot water treatment at 46°C and 50°C for 10 min. Result: Among all the treatments, T4-Magnetic field (200 mT) gave the best results in field and lab conditions of field emergence (98.610) and germination% (98.5), Magnetic field (400 mT) shown the good results and significantly higher values of all other yield (45.867, 78.833, 660.480, 165.120) and morphological traits as well as seed quality parameters like shoot length (86.925), root length (44.55), seedling length (13.131), vigour index- I and II (1267.138 and 5.058), fresh (0.343) and dry (0.0524) weight of seedlings and comparatively control (T0) was observed lowest to other treatments. As such, Magnetic treatment is quite effective for seedling establishment to overcome low germination and yield which helps in Qualitative and Quantiative seed production of Millets in sustainable agriculture.

An experiment was conducted to study the effect of presowing seed treatment, sowing windows and seasons on seed yield and quality of greengram by sowing the treated seeds on two dates each in summer and kharif. The treatments viz., 8 hours of water soaking; priming with 100 ppm MnSO4, 1% neem leaf extract, 5 ppm GA3, 1% KCl; coating with 10 ml linseed oil, 50 gm rhizobium, 4 g Trichoderma per kg seed; combination of neem leaf extract priming and rhizobium coating, combination of linseed oil and rhizobium coating. Seed quality and yield was highly influenced by seed treatments, dates and seasons; treatment and seasonal effects being greater than sowing dates. GA3, KCl and MnSO4 primed seed found most effective for enhancing the seed quality and yield. Summer season was better than kharif season for both seed quality and yield

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.

Sowing Seed

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.

Regulatory Flexibility

Seed rules and regulations determine who can produce and sell seeds, which varieties will be available in the market, the quality of seed for sale, and where seed can be bought and sold. The legal and regulatory environment for seed impacts all stakeholders, including those in the informal sector, through shaping who can participate in the market and the quality and diversity of seed available. This paper addresses a gap in the current literature regarding the role of law and regulation in linking the informal and formal seed sectors and creating more inclusive and better governed seed systems. Drawing upon insights from the literature, global case studies, key expert consultations, and a methodology on the design and implementation of law and regulation, we present a framework that evaluates how regulatory flexibility can be built into seed systems to address farmers’ needs and engage stakeholders of all sizes. Our study focuses on two key dimensions: extending market frontiers and liberalizing seed quality control mechanisms. We find that flexible regulatory approaches and practices play a central role in building bridges between formal and informal seed systems, guaranteeing quality seed in the market, and encouraging market entry for high-quality traditional and farmer-preferred varieties.
