Relevance. Vegetable seed production is a key step in using of new varieties/hybrids in agriculture. The main problem of vegetable seed production is the negative effect of environment to the seed productivity of plants and seeds quality. Usually, vegetable seeds produce in greenhouses in Russia, but special greenhouses are necessary for the obtaining of qualitative seeds. Possibilities different types of greenhouses for seed production of new special tomato varieties for multi circle hydroponics have been studied at this paper.Materials and methods. Materials of study: plants, fruits and seeds of two new tomato varieties Natasha and Timosha. Influence type of plants cultivation on the yield, plant productivity, the middle mass of the fruit and seeds quality have been studied at the two factorial experiment, which has been carried out with help of random repetitions method with 4 repeats. Seed quality has been evaluated by GOST 32 592-2013. Experimental data have been calculated with dispersion analysis by B.A. Dospekhov (1985).Results. It has been established, that the environment of “Rishel” greenhouse (France firm “Rishel”) with polycarbonate cover is optimal for the seed production of new tomato varieties Natasha and Timosha for multi circle hydroponics. The productivity and the yield of seed’s plants were significantly higher in “Rishel” greenhouse, than in the usual greenhouse. The middle mass of one fruit at the plant was significantly higher too. The quality of seeds was in accordance to GOST 32 592-2013 for qualitative tomato seeds (2014).

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.

Установлено, что на пойменных почвах использование методов диагностики минерального питания растений моркови «по почве» и «по черешку» в фазу начала образования корнеплодов позволяет значительно (на 36–42%) снизить расход минеральных удобрений, обеспечивая урожайность моркови на уровне 70 т/га с долей стандартной продукции 78–81% без существенного изменения качества корнеплодов.It was found that in floodplain soils, the use of methods of diagnosis of mineral nutrition of carrot plants «on the soil» and «on the petiole» in the phase of the beginning of the formation of root crops can significantly (by 36–42%) reduce the consumption of mineral fertilizers, ensuring the yield of carrots at the level of 70 t/ha with a share of standard production of 78–81% without significantly changing the quality of root crops.

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.

High Temperature Drying

Mechanical drying has frequently caused injury in corn seed. Changes in seed moisture, temperature, and quality were determined for inbred lines A632, B73 and Mo17 to define the relationship between these variables. Ears harvested at ca. 48 and 38% seed moisture could be dried at 50 °C for 4–15 h and 18–24 h, respectively, before germination started to decline linearly with prolonged 50 °C drying. Drying time at 50 °C, seed moisture, or embryo moisture after 50 °C drying could be used equally well for prediction of seed quality. Seedling dry weights often declined even when seed was dried for only a few hours at 50 °C. Temperature measurements within seeds indicated that evaporation cooled the seed no more than 5 °C. Drying susceptibility of seed parents varied greatly between years.Key words: Moisture, temperature changes, seed corn, drying

Leaf Powder

Laboratory studies were conducted with leaf powder of three plants to show the preservative effect for maintaining the quality of lentil seeds in storage. After processing and drying, seeds were preserved with different botanicals and stored them in earthen pots for eight months. Botanicals, such as whole leaf powder of neem (Azadirachta indica), dholkalmi (Ipmoea sepiara), and bishkatali (Polygonum hydropiper) were used at a dose of 5% w/w (25 g botanical per 500 g of lentil seeds). The lentil seeds were stored till next planting time and seed quality, such as moisture content, germination capacity, root length, shoot length of the seedlings and vigour index were observed. The highest values for all these characters except moisture content were significant when the seeds were preserved with neem leaf powder and bishkatali. Among three botanicals, dholkalmi was less effective. Keywords: Lentil; botanicals; storage; seed quality DOI: http://dx.doi.org/10.3329/bjar.v36i3.9266 BJAR 2011; 36(3): 381-387
