Effects of seed spacing on green pea yields were investigated at nine locations during three successive cropping seasons. Dark Skin Perfection (freezer) and Medalist (canner) were seeded with and without applied N-P-K fertilizer in rows spaced 8.9, 13.3 and 17.8 cm apart with various in-row spacings of 3.8–10.2 cm. Yields of shelled peas harvested at the proper stage for processing and adjusted to tenderometer 100 were not substantially affected by the spacing or fertilizer treatments. The addition of 15-15-15 fertilizer at 392 kg/ha tended to increase vine length and delay maturity but the effects were slight and generally not significant. The spacings employed had no effect on vine length, pea/vine ratio or maturity.

The effects of nitrogen, phosphorus, and potassium on the yields of Dark Skin Perfection peas were investigated at nine locations during three successive cropping seasons. All three nutrients were applied broadcast at rates of 0, 30, 60, and 90 kg/ha in randomized block experiments with four replicates. A lime treatment was also included consisting of an application of dolomitic limestone in the furrow with the seed at the rate of 400 kg/ha. Yields of shelled peas, adjusted to tenderometer 100, varied from approximately 4 to 7 tonnes/ha and were not substantially affected by the fertilizer or lime treatments. Germination was in the range of 85–95% and was not affected by the treatments. Vine length tended to increase as the rate of all three nutrients was increased, but the pea/vine ratio (by weight) was not affected. Maturity was slightly delayed by increasing rates of added nitrogen and slightly advanced by increasing rates of added phosphorus.

The changes of tenderness of three green pea varieties with different maturity were studied after Fertileader® Vital fertilizer treatment. The fertilizer treatment caused signifi cant differences in the tenderness of treated plants in every year. After the second measuring time; the treated plants showed better quality than the control ones. The treated varieties kept their tenderness longer due to this foliar fertilizer, the yield have better quality so even better suited to the requirement of canning industry. Use of Fertileader® Vital is of an economic importance because high economic benefi t can be realized in one hectare after Fertileader® Vital treatment. By using this foliar fertilizer 12,840 HUF extra profi ts can be realized by producing green peas of I. quality class instead of yield with II. quality category. This extra profit could increase to 447,840 HUF considering that green peas belong still to the II. quality class after fertilizer treatment when the quality of non-treated plants are no more suitable for the canning industry.

Relevance. The purpose of the research was to produce a new medium-ripe, high-yielding variety of vegetable peas with the usual type of leaf to expand the variety in the now used conveyor variety selection of the Krymsk EBS VIR Branch.Materials and methods. The experience was laid on the fields of the Krymsk EBS VIR Branch (Russia, Krasnodar Region, Krymsk) in 2019-2020. Varieties and strain were evaluated in a competitive variety testing. Sowing was carried out with a selection seeder SKS-6-10. The plot area was 10 m2 , the experiment was repeated four times. In the phase of technical ripeness, the sheaves were selected for description and the yield was taken into account. The conservation of green peas was done at the Tech Evaluation Lab.Results. Competitive variety testing in the mid-ripeness group was held by two strains 2014/7 and 344/16. The strain 2014/17 for green pea yields surpassed the standard "Parus" and G-344/16 in both years of study. Fresh and processed green peas were rated by the Tasting Commission at 5.0 and 4.8 points, respectively. High yield is achieved due to the paired beans on the peduncle and a large number of grains in the bean, up to 10 pieces. The grain in technical ripeness has a dark green color and the linear dimensions are 9.0x8.1 mm. In biological maturity, the seeds are intensely green, angular-compressed with a mass of 1000 pieces. 188-225 g.Conclusion. The results of field and laboratory analyses carried out on the complex of economicvaluable characteristics made it possible to distinguish the strain 2014/7, which in 2020 was transferred to the State Variety Testing under the name "Patriot". It is recommended as a supplement to the existing set of vegetable pea varieties of the Krymsk EBS VIR Branch in the mid-ripe group.

AbstractThe escape fraction of Lyman continuum (LyC) radiation from galaxies remains one of the primary uncertainties in studies of reionization. However, few LyC-emitting galaxies are known. The recently identified, low-redshift “Green Pea” (GP) galaxies exhibit a number of similarities with high-redshift galaxies, and their optical emission lines suggest they may be some of the elusive LyC emitters. Recent HST COS and ACS observations of four GPs suggest further evidence for LyC escape and give new insights into the origins of Lyα and low-ionization UV lines in high-redshift galaxies. The Lyα emission and low-ionization emission and absorption lines provide a coherent physical picture of the neutral gas distribution in the GPs and may identify LyC emitters at high redshift. The rare, low-redshift GPs hint at possible factors that may enable LyC and Lyα escape from high-redshift galaxies.

AbstractYoung low-mass galaxies with extreme emission-line properties are ubiquitous at high redshift. However, a detailed characterisation of their physical properties, key for understanding cosmic reionisation and the early growth of galaxies, will be only possible with JWST and ELT observations. Rare lower-z analogues of these primeval galaxies provide us ideal laboratories to study in larger detail the complex physical mechanisms taking place in these extreme systems. In this talk, I will review key results from these high-z analogues, with an emphasis on lessons learned from deep spectroscopic observations of green pea galaxies at z ⩽ 0.3. New recent results based on high-dispersion Echelle and IFU spectroscopy of green peas will be presented. They illustrate current advantages and limitations of the chemodynamical analysis for a simultaneous study of the ionised gas kinematics, chemical enrichment and the escape of ionising photons in compact low-mass starbursts.

1. An account is given of Marsh Spot in the seeds of the green pea (Pisum sativum L.); its economic importance and its effect on the plant, including the germination of the seed, are discussed.2. Hypotheses advanced by seedsmen and growers to account for the presence of Marsh Spot are discussed.3. The soils of 165 fields upon which green peas were grown under contract for seed in east Kent during 1933 and 1934, were surveyed in detail and are classified under the American system. A brief description of each is given.4. The occurrence of Marsh Spot is correlated with the presence of a water table in the soil. A high percentage of Marsh Spot was encountered only in crops grown on fields with a water table within 52 in. of the surface. Thus, in the presence of a water table, the intensity of Marsh Spot reached a maximum of 100 per cent. of the seeds of a sample affected, whereas in the absence of a water table the maximum was only 3 per cent.

AbstractHow galaxies reionized the universe remains an open question, but we can gain insights from the low-redshift Green Pea galaxies, one of the only known populations of Lyman continuum (LyC) emitters. Using VLA H i 21 cm observations and HST UV spectra of Green Peas, we investigate how neutral gas content and geometry influence LyC and Lyα escape. Our results suggest that LyC Emitters may have high ratios of star formation rate to H i mass. Low gas covering fractions are common among the population, but not all sightlines are optically thin. Based on the observed relationship between high ionization parameters, low metallicities, and narrow Lyα profiles, we propose that weak stellar feedback at low metallicities results in a gas geometry of dense clumps within a low-density medium, which facilitates Lyα and LyC escape. We address the implications of these results for identifying LyC emitters at high redshift with JWST and ALMA.

SummaryField experiments were made in the rainforest zone of Western Nigeria over three cropping seasons on the effects of potassium fertilizer of one local cassava cultivar 53101 and two improved cultivars 60506 and 60447 which were F1 hybrids of the former. The results showed that K-fertilizer increased the starch yields only slightly. Cultivar 60506 produced significantly higher starch yields (P < 0–01) than the local strain, 53101, while cultivar 60447 gave lower starch recovery than the local cultivar.A definite influence of K application on the cyanide (HCN) content of the tuber roots could not be established. The peeled tubers of the improved cultivars contained much less cyanide than those of the local 53101 strain (P < 0–01). Potassium had the highest (0·72–1·28% dry weight basis) while phosphorus had the lowest concentration (0·06–0·12%) in the peeled tuber. Owing to its higher yielding capability the unfertilized 60506 removed larger amounts of potash (average 110·9 kg k20/ha) from the soil than unfertilized 53101 (average 82·2 kg k20/ha).

Recommendations of N, P and K fertilization presently made for vegetable production in Quebec need to be verified through local field studies. To this end field trials were made on 11 soils located in the Montreal, Nicolet and Quebec-Portneuf areas, through the year 1978–1980. Fertilization increased green pea yields in seven trials out of 16; most of these increases were caused by phosphorus applications. Similar results were obtained with snap beans, except that this crop tended to require a somewhat greater quantity of applied N. Fertilizer requirements of these crops were obtained by fitting Mitscherlich or polynomial equations to field data. Accordingly 15–30 kg N/ha seem to be required by green peas and snap beans, respectively, to obtain optimum yields. Modification of present soil test norms is suggested for phosphorus and potassium fertilization. For these crops the suggested rates are 20, 40 and over 60 kg P/ha for soils with high, moderate or low levels of available P and the minimum rate of 20 kg K/ha for every level of K except for the low level which would require about 40 kg K/ha for green peas.

This research was conducted to determine the drying, rehydration behavior and color parameters changes of green peas when microwave drying at different temperatures. For drying, 6 drying kinetics models were applied. The values of L*, a*, b*, C* and Ho were measured to determine the effect of the microwave drying on the color parameters. The most suitable model was the parabolic model in microwave drying of green peas. Effective diffusion coefficients changed between 2.50x10-9 m2s-1 and 8.16x10-9 m2s-1. The activation energy was found as 1279.7 W/g. Equilibrium moisture contents ranged from 1.982 to 2.491 according to the Peleg Model and could not reach the initial moisture content at all microwave output powers after rehydration. L*, a* and b* color parameters were significantly influenced by microwave drying, while C* and Ho values were not the much affected.
