The Cost

The onion bulb production In Mexico is about 39,000 ha annually. Yield is variable according to the technological capacity and economic condition of the grower. However, The technology adoption (new varieties, efficient irrigation system and establishment methods) is increased during the last years. Traditionally in Mexico the grower use the manual transplant of seedling, that which increases the cost and time of this labor. The objective of the present Experiment was to evaluate Two establishment methods (direct seed and transplant seedling) and the effect on 24 bulb varieties. The evaluation was carried out in INIFAP-CIRNO Experimental Station in furrows with 1.00 m of separation among them, with double row of plants, the amount of nitrogen and phosphorus used were 180 and 80 kg·ha-1 respectively, we used the drip irrigation system. In this experiment we observed that the system of direct seed obtained better yield (18%), bulb weight (21%) and precocity (11 days) in comparing to the transplant methods, however in the first treatment the floral stem emission was greater (6.7% vs 1.1%) of the transplant methods. The white varieties with high yield were: White onion 214 and Cal 128 with 71.4 and 65.7 ton/ha. The purple varieties was F1 Cal 192 with 68.3 t·ha-1 and the yellow varieties was Ringer Cal 160 with 63.2 t·ha-1.

Yield And Quality

Fertigation is a promising strategy to improve nitrogen use efficiency, yield, and quality of cabbage (Brassica oleracea var. capitata), but there is a lack of data relevant to growers in Ontario. Field trials were conducted in 2003 and 2004 to determine the optimum rate of water and nitrogen application in terms of yield and quality of `Huron' cabbage. Treatments consisted of combinations of target soil moisture levels (25% to 100% field capacity) and nitrogen fertilizer (0–400 kg·ha-1 N) as dictated by a central rotatable composite design. Nitrogen applications were split with 50% broadcast and incorporated before planting and the remaining split into weekly applications via a trickle irrigation system. Water was applied two to three times per week to bring soil moisture up to the target levels. Maximum marketable yield was reached at a combination of 400 kg·ha-1 N and a soil moisture target of 100% field capacity. Many heads were undersized or undeveloped at low rates of nitrogen. Applications of nitrogen required for high yield and quality can pose a risk of leaching; however, use of fertigation minimizes potential in-season leaching. Estimated total residual nitrogen at harvest ranged from 83–211 kg·ha-1 N, which could have a negative impact on the environment. Thus, there is a considerable challenge to reduce environmental impact without economic losses. Improved knowledge of in-season nitrogen requirements might further reduce the levels of nitrogen applied without reducing yield and quality.

The range of modern domestic and foreign fertilizers is constantly growing. Now the composition of fertilizers for foliar fertilizing, in addition to the main macronutrients, includes a large amount of trace elements necessary in a specific growing season. Such fertilizers are convenient for the use in tank mixtures with pesticides and are quite popular nowadays. This work is devoted to the comparative analysis of five different combinations of fertilizers: Basaplant (Germany), Nutrimix (EuroChem, Russia), water-soluble fertilizer NPK 20-20-20 (EuroChem, Russia) as a soybean foliar fertilizing in the Orel region. As a result of the research, it was found out that the use of foliar fertilizing has a positive effect on the yield and quality of soybean variety Oak prudence. In terms of soybean yield in comparison with other options, the option with The EuroChem 20-20-20 fertilizer proved to be the best one, which indicated the efficiency of its use in the conditions of the Orel region. High yield of soybean grain in the studied fertilizer application options was due to a large number of beans and seeds on the plant, as well as high seed productivity of these options. The optimal values of the acid index of the oil had variants with EuroChem+Nutrimix and EuroChem 20-20-20. The calculation of the economic efficiency of soybean cultivation based on the variants of the experiment showed that it was the most profitable to cultivate soybeans in the conditions of the Orel region with the use of EuroChem 20-20-20 fertilizer. The profitability of this option was the maximum and amounted to 65%. The use of alternative more expensive fertilizer Basaplant (Germany) as a foliar fertilizer leads to an increase in the cost of production and reduces the profitability of production

Bbell pepper (Capsicum annum L.) production is an appropriate alternative for the northeastern Sonora, México (Magdalena River). Because of the fresh temperature conditions of this region, production is possible in spring and summer. However, it is necessary to have appropriate varieties with a high potential for quality and yield under these conditions. The objective of this research was to evaluate the yield and quality of six varieties of bell pepper. The evaluation was carried out at the INIFAP-CIRNO Experimental Station (Magdalena of Kino, Sonora) in Spring 2002 under field conditions. The evaluated varieties were: `Baron', X3R Wisar, PS 236894, `Bamoa', `Admiral', and `Navolato'. The date of seedling transplant was 29 Mar. in furrows with 1 m of separation and 0.33 m between plants under a drip-irrigation system. In the trials, we used a completely randomized design with four replications. The measured variables were yield and fruit weight. The harvest period was 26 June to 23 Aug. The results indicated that the highest yields were obtained from: `Baron', X3R Wisard, and PS 236894 with 43.2, 42.3, and 38.8 t·ha-1, respectively, and the lowest yields obtained were from `Admiral' and `Navolato', with 33.3 and 30.0 t·ha-1, respectively. The highest fruit weights corresponded to PS 236894 and X3R Wisard with 145 and 140 g, respectively.

Relevance. A priority in the selection of watermelon is the creation of new competitive varieties that combine resistance to adverse stressors, high yield and excellent fruit quality. The purpose of this study is to show the influence of weather conditions on the growing season, yield and quality of watermelon fruits and the influence of growing conditions on the growth and development of watermelon plants.Materials and methods. The study used 5 varieties of watermelon included in the State Register and 2 new varieties, ready for transfer to the State Variety Test. During the research, all observations and counts were carried out in accordance with the State Variety Testing Methodology and the Field Experience Methodology.Results. In the process of research, it was found that the length of the growing season largely depends on the amount of precipitation and the sum of active temperatures, as well as on their distribution in interphase periods. It was noted that in the year with the highest rainfall, the growing season was the longest. Productivity for the analyzed period varies from 14.2 t / ha to 20.7 t / ha in the early group, from 19.4 t / ha to 24.9 t / ha in the average. The highest yields were recorded in 2017 with the least rainfall. Growing conditions had a significant impact on the quality of watermelon fruit: the solids content ranged from 9.4% to 12.8%, total sugar - from 7.70% to 11.35%.

Water pumping restrictions of high-quality irrigation water from underground aquifers is affecting vegetable production in Southwest Texas. There is a need to develop efficient deficit-irrigation strategies to minimize irrigation inputs and maintain crop profitability. Our objective was to determine how growth, yield, and quality of cantaloupe (Cucumis melo L. cv. `Caravelle') are affected by irrigation systems with varying input levels, including drip depth position and polyethylene mulch. Stand establishment systems used were containerized transplants and direct seeding. Field experiments were conducted on a Uvalde silty clay loam soil. Marketable yields increased in the order of pre-irrigation followed by: dry-land conditions, furrow/no-mulch, furrow/mulch, drip-surface (0 cm depth)/mulch, drip-subsurface (10-cm depth)/mulch, and drip-subsurface (30 cm depth)/mulch. Pooled across all drip depth treatments, plants on drip had higher water use efficiency than plants on furrow/no-mulch or furrow/mulch systems. Transplants with drip-surface produced 75% higher total and fruit size No. 9 yields than drip-subsurface (10- or 30-cm depth) during the first harvest, but total yields were unaffected by drip tape position. About similar trends were measured in a subsequent study except for a significant irrigation system (stand establishment interaction for yield. Total yields were highest for transplants on drip-subsurface (10-cm depth) and direct seeded plants on drip-subsurface (10 and 30 cm depth) with mulch.

An optimum physiological condition will support high yield and quality of cocoa production. The research was aimed to study the effects of stomatal conductance and chlorophyll content related to cocoa production under three shade regimes.This research was conducted in Kaliwining Experimental Station, elevation of 45 m above sea level with D climate type based on Schmidt & Fergusson. Cocoa trees which were planted in 1994 at a spacing of 3 X 3 m were used in the study planted by using split plot design. The shade tree species were teak (Tectona grandis), krete (Cassiasurattensis), and lamtoro (Leucaena sp.) as the main plots, and cocoa clones of Sulawesi 01,Sulawesi 02, KKM 22 and KW 165 as sub plots. This study showed that there was interaction between cocoa clone and shade species for stomatal conductance where stomatal diffusive resistance of KKM 22 was the best under Leucaena sp.and Cassiasurattensis with the values of 1.38 and 1.34 s.cm -1, respectively. The highest chlorophyll content, stomatal index and transpiration values was under Leucaena sp. shade. There was positive correlation between chlorophyll content and transpiration with pod yield of cocoa. The highest yield and the lowest bean count wereobtainedon Sulawesi 01 clone under Leucaenasp. shade.Keywords: stomatal conductance, transpiration, diffusive resistance, shades trees, clones,pod yield

Boron is an important micronutrient, required for all plant growth, and critical for high yield and quality of crops. The aim of the present research was to determine the effects of boron on pot-grown parsley (Petroselinum sativum Hoffm.). The experimental design consisted of four treatments using Hoagland-Arnon (1950) nutrient solutions with two different boron concentrations (B1 - 15 ppm and B2 - 150 ppm), each with and without 10 ml humic acid addition (HB1 and HB2), and controls with full strength Hoagland-Arnon solutions. Growth analyses of the parsley revealed that 15 ppm boron application caused an increase in root length leaf fresh and dry weight root fresh and dry weight and leaf area compared to control values. 150 ppm B (B2) concentration decreased all growth parameters compared to controls. The two humic acid treatments (HB1 and HB2) did not increase any of those growth parameters either in controls (C) or in the two boron (B1 and B2) concentrations. Analysis by (ICP-MS) revealed that B content in the leaves increased gradually in B1 and B2, as well as in both humic treatments where in HB2 it increased to 99.38% compared to B1. In the leaves, Mn, Zn and Fe contents behaved the same as B, increasing in all treatments, with the amounts in HB2 being significantly greater than in C, B1 and B2 leaves.

Standard Diet Group

One of the most commonly used protein sources in rodent diets is soy, which is naturally rich in phytoestrogens. Although phytoestrogens have shown potential health benefits in humans, they may also have the ability to disrupt reproduction. Consequently, there has been a tendency to try to exclude them from rodent diets. In the current study, we investigated whether phytoestrogen content in the mouse diet could affect reproduction in mice used as embryo donors. Donor mice (C57BL/6JOlaHsd) were maintained with three different diets: high phytoestrogen (ca. 400 mg/kg genistein), low phytoestrogen (ca. 10 mg/kg genistein) and standard breeding diet (ca. 120 mg/kg genistein). Mice fed a high phytoestrogen diet had a high yield of plugs, embryos, and injectable embryos, as well as producing good quality embryos. Results from donor mice fed a low phytoestrogen diet were consistently but only slightly inferior, whereas mice fed a standard diet performed the poorest. Interestingly, the largest number of born and weaned offspring were observed when recipient females received embryos from the standard diet group. Sperm yield and quality of stud males did not differ between the groups. We surmize that for experimental endpoints requiring fertilized embryos it may be more beneficial to feed mice a diet containing phytoestrogen, but if the goal is to produce transgenic mice, a diet high in phytoestrogen may be inadvisable. In conclusion, care should be taken when selecting a diet for experimental mouse colonies as phytoestrogen could influence the study outcome.
