Field Emergence and Plant Density of Sand Bluestem Lines Selected for Increased Seed Germination

Pelleting is a physical pre-sowing seed management technique, in which seeds are enclosed with biopromotive substances to improve the field stand. To evaluate the efficacy of plant herbal powders for seed pelleting, studies were initiated with blackgram cv. ADT 3, in which seeds were pelleted with the leaf powders of noni (Morinda citrifolia) and basil (Ocimum sanctum) and fruit powder of gallnut (Terminalia chebula) @ 200 g kg-1 of seed using Carboxy methyl cellulose @ 200 ml per kilogram of seed as an adhesive. The results revealed that seeds pelleted with the leaf powders of either basil improved the seed germination by 6% and seedling vigour (23%), seedling length (9%) and seedling dry weight (5%). In raised bed nursery, the seeds pelleted with basil leaf powder @ 200 g kg-1 of seed recorded improved field emergence (7%) with higher chlorophyll index (30%) and nodule number (28%) highlighting the efficacy of the treatment. While, the seeds pelleted with gallnut fruit powder recorded lowest germination, vigour and field emergence which is significantly lesser than control. The delayed emergence, germination and vigour was due to the increase in hardiness of gallnut powder pelleted seed. Thus, the seeds treated with basil leaf powder @ 200 g kg-1 using carboxy methyl cellulose @ 200 ml per kilogram of seed as an adhesive, enhanced seed germination, vigour, seedling length and dry weight.

Studies were conducted at East Lansing, MI, in 1994 and 1995 to examine corn yield response to giant foxtail interference and to examine the effect of giant foxtail density on giant foxtail biomass, seed production, and seed germination. Treatments consisted of 0, 10, 30, 60, 84, and 98 giant foxtail plants m−1of row in 1994 and 0, 10, 27, 30, 60, and 69 plants m−1of row in 1995. The influence of giant foxtail density on corn yield fit a hyperbolic equation. Corn yields were reduced 13% in 1994 and 14% in 1995 from 10 giant foxtail plants m−1of row. Corn dry matter at maturity was decreased 24 and 23% from 10 giant foxtail plants m−1of row in 1994 and 1995, respectively. Giant foxtail seed production increased linearly as inflorescence length increased. The length of a single giant foxtail inflorescence increased as plant density increased and the number of inflorescence produced per plant decreased. Giant foxtail seed production ranged from 518 to 2,544 seeds per plant. Ten giant foxtail plants m−1of row produced 15,700 seeds m−2. Giant foxtail seed germination was not affected by plant density.

Intensive Growth

Purpose. It is theoretically possible to substantiate and practically determine the degree of growth and development of stevia plants and their productivity depending on the use of the Avatar-2 microfertilizer. Methods. Laboratory, field, analytical, statistical. Results. During the years of research, the highest productivity of stevia agrophytocenoses was obtained in the variant with soaking (pre-sowing) of seeds in microfertilizer Avatar-2 + twice foliar fertilization. Plant density before harvest was by 10.5 thousand/ha, yield of green mass by 3.3 t/ha and including leaves by 2.5 t/ha, dry matter yield by 0.7% (including leaves by 0.3%) higher than in the control. Conclusions. The main effect of soaking seeds in the trace element formulation Avatar-2 (registered in Ukraine in 2006) in the technology of growing stevia is to increase the efficiency and uniformity of seed germination in both laboratory and field conditions, which promotes more intensive growth and development of plants during the vegetation, and when applied in the end of vegetation, to better preserve them and increase the yield of green and dry matter.

Trigonella Foenum Graecum L

Sixteen diverse genotypes of fenugreek (Trigonella foenum-graecum L.) were grown in five (E1 to E5) environments which were created by different date of sowing during the rabi seasons at the Vegetable Farm of CCS HAU, Hisar. (29°15ˈN, 75°69ˈE) during 2012-13. Observations were recorded on ten randomly selected plants from each genotypes in each replications for characters viz. field emergence index, days to 50 % flowering, plant height, number of pods per plant, number of branches per plant, number of seeds per pod, pod length, seed yield (q/ha), test weight, seed germination, seed vigour index-I and II. The estimation of genotypic and phenotypic coefficients (GCV and PCV) variation in all the environments was consistently decreasing with the delaying in sowing date for all the character studied except plant height and test weight indicating that the environmental influence was comparatively more pronounced for these characters in expressing the phenotypic performance of different genotypes. Highest GCV and PCV was estimated as 50.36 % and 55.93 %, respectively for seed vigour index-I in E1. High value of heritability estimated for characters seed yield, seed vigour index-II, seed germination and branches per plant (above 70 %) in E1 revealed that these were less influenced by environment and low heritability estimated for days to 50 % flowering in E2, plant height in E2, seeds per pod in E3, field emergence index in E5 indicated high influence of environment. Based on environmental indices, the environment E2 was most favourable for all the characters studied except field emergence index.

Overall Mortality

Marketing the inflorescences of Comanthera elegans (Bong.) L.R. Parra & Giul. represents a source of income to many families from extractives communities in the portion of the Espinhaço Range located in the state of Minas Gerais, Brazil. Cultivating this species stands out by allying income generation with conservation since the species is currently endangered. This study aimed to assess aspects of the development of C. elegans in three cultivation systems: beds, rows, and whole area. Sowing took place in January 2009 and the inflorescences were harvested in May 2010, which characterized the experimental period. Emergence; plant density; rates of flowering, mortality, resprouting, and recruiting of new individuals; and production of inflorescences per plant and per area were assessed. Emergence began approximately 50 days after sowing. Plant density ranged from 130 to 350 plants.m-2 among the three cultivation systems. The highest mortality rate (18%) was observed at the peak of the dry season (August) and the overall mortality rate over one reproductive cycle was 49%. Of the plants that lost the aerial part, 36% resprouted. Sprouting and seed germination accounted for 30 and 3% of the recruiting of new individuals, respectively. C. elegans had two bloom (AprilMay 2009 and April-May 2010): 5.4% of the plants bloomed in the first season and 78%, in the second. Each plant produced between three and 178 inflorescences and the highest inflorescence production in terms of weight (232 g.m-2) and number (2,910 inflorescences.m-2) was observed in the cultivation in beds at 1,624 kg.ha-1.

Healthy Seed

Seed perform a vital role in agricultural sector for crop production as well as seed business. Scarcity of healthy seed hinder not only the crop production but also the quality of seed. Storing of healthy seed with proper storing condition is one of the suitable methods to maximize production however, healthy seed also lose its quality during seed storage. Seed remains viable for long time if the seed stored by maintaining seed moisture content, storage temperature with storage container. So, this experiment was carried out to observe the quality parameters of jute seed during long term storing. To find out the storage effect an experiment was conducted on march, 2020 at seed laboratory, Jute Agriculture Experimental Station, Jagir, Manikganj, Bangladesh during the period of January 2016 to March, 2020. Plastic pot was used in this experiment as a storage container to store jute seeds. Three tossa jute (C. olitorius L.) varieties viz., O-795 (V1), O-9897 (V2) and OM-1 (V3) were used in this study. Result revealed that storage period and jute variety showed significant effect on different seed quality parameters. The highest seed germination, field emergence, seed vigour and the lowest 1000-seed weight, moisture content were recorded in T5 (2019-20) treatment. On the other hand, the lowest seed germination, field emergence, seed vigour and the highest 1000-seed weight, moisture content were recorded in T1 (2015-2016) treatment. Furthermore, seed germination, field emergence, seed vigour was negatively but 1000-seed weight was positively correlate with moisture content. Results revealed that extended storage period caused the decreasing seed quality and seed can be stored for three years in plastic container without hampering the seed quality.
