Greenhouse experiments were carried out to determine the tolerance of two radish cultivars to soil-applied B, Mo, and Zn. Sources used were boric acid (0, 54, 108, 216, 324, and 432 ppm), molybdic acid (0, 1.4, 2.8, 5.6, 8.5, and 11.3 ppm), and zinc sulfate (0, 40, 80, 160, 240, and 360 ppm) applied at planting in addition to the control. Plants were grown in plastic containers of 1.5 L, filled with a potting medium composed of 50% vermiculite, 30% sphagnum peat, and 20% perlite. Treatments were arranged within a randomized complete block design with six replications. Fresh weight of commercial roots was not affected by Mo or Zn applications in either cultivar. However, B applications decreased root fresh weight as rate increased. These results suggest that these radish cultivars perform well in a relatively wide range of Mo and Zn application rates, whereas tolerance to B appears to be low.

An ideal spacing between plants should be established for the optimization of radish (Raphanus sativus L.) crops since the plant spatial distribution of plants affects the crop yield.  This study was conducted aiming to evaluate the agronomic performance of radish cultivars grown under different spacings. The experiment was conducted at the Experimental Field of the Federal Institute of Education, Science, and Technology of Maranhão, in Codó, MA, Brazil, from June to July 2017. The experiment was conducted in a randomized block design with five replications, using a 2×2 factorial arrangement. The factors consisted of 2 cultivars (Sparkler Ponta Branca and Saxa) and 2 spacings between plants (5 and 8cm), totaling 20 experimental plots. Data were collected in  6  plants from each experimental plot. The agronomic parameters: total fresh weight (TFW), root fresh weight (RFW), root mean diameter (RMD), root means length (RML), and root yield (RY) of the radish plants were evaluated. The factors (cultivars and spacing between plants) had no significant effect on TFW, RFW, RML, and RMD. The spacing between plants has a significant effect on the yield of radish crops of the cultivar Saxa, and higher yields are found when using the spacing of 5cm.

<em>Radish (Raphanus sativus L.) is popular in the world as a root vegetable. In Indonesia, the yield of radish is low due to several factors such as the cultivation system. Fertilization and mulching are among the cultivation system which are widely known to improve crop growth and yield. The research aimed to study the effect of bokashi-fertilizer and mulch combination on yield of radish (Raphanus sativus L.). A field experiment was conducted at the Experimental Garden of Agriculture and Agricultural Technology Faculty, The State University of Papua, Manokwari. This experiment was set up in a randomized block design, consisting of three kinds of bokashi namely firewood/ashwood-bokashi (B1), firewood-bokashi (B2), ashwood-bokashi (B3) and four kinds of mulches consist of transparent plastic mulch (M1), black/silver plastic mulch (M2), gliricida mulch (M3) and imperata mulch (M4). The overall treatments were as follows: control, B1M1, B1M2, B1M3, B1M4, B2M1, B2M2, B2M3, B2M4, B3M1, B3M2, B3M3, B3M4. The results show that yield of radish was not affected by application of the bokashi and mulch combination. Even though, no statistically significant, the application of bokashi and mulch increased plant fresh weight by 59%, tuber fresh weight per plant 61.28%, leaf weight 45.79%, tuber length 19.38% and tuber diameter 22.38% compared to control.</em>

Raphanus Sativus L

The use of saline or low-quality water in agriculture is an alternative to increasing water demand, especially in arid or semi-arid regions. However, the use of water with high levels of salts causes disturbances in plants, which can lead to their death; thus, alternatives to mitigate these effects are relevant in current agriculture. Currently, antioxidants are used to mitigate the effects of salts in plants, and among them ascorbic acid has been frequently mentioned. Therefore, the aim of this study was to evaluate the effect of irrigation with saline water combined with applications of ascorbic acid on the development and photosynthetic activity of radish (Raphanus sativus L.) plants. This experiment was carried out in a greenhouse with a randomized block design, with the treatments distributed in a 5.5 incomplete factorial scheme, composed of five electrical conductivities of the irrigation water (ECw): 0.50, 1.30, 3.25, 5.20 and 6.00 dS m-1, and five ascorbic acid (AA) doses: 0.00, 0.29, 1.00, 1.71, and 2.00 mM. The evaluated variables were: shoot height, leaf number, tuberous root diameter, chlorophyll a, b and total content, chlorophyll a/b ratio, initial fluorescence, maximum fluorescence, variable fluorescence and quantum yield of photosystem II. The saline water influenced the analyzed variables in the radish crop regardless of the ascorbic acid application. The ascorbic acid was not efficient in attenuating the deleterious effect of salinity in the irrigation water on the development and fluorescence of the radish. However, it was observed that the concentration of 1.00 mM of ascorbic acid promoted an increase in chlorophyll a, b and total in the saltstressed radish plants.

Twenty-two sweet potato [Ipomoea batatas(L.) Lam.] clones with a wide range in metribuzin [4-amino-6-(1,1-dimethylethyl)-3-(methylthio)-1,2,4-triazin-5(4H)-one] tolerance were used to establish narrow sense heritability estimates (h2) using a greenhouse procedure. The heritability estimates were obtained from simple linear regressions (h2= 2b) of injury rating, shoot fresh weight, and change in shoot fresh weight of offspring against the same responses of parents at metribuzin concentrations of 0, 0.3, and 0.6 ppm in the potting medium and averaged data for the two concentrations. These values ranged from 0.85 to 1.0, indicating that a recurrent mass selection process should be an appropriate approach to developing metribuzin-tolerant cultivars. Several highly tolerant clones were identified.

Diversification of plant species is needed to anticipate price fluctuation of vegetables. Intercropping system compared to monoculture can give more benefits to farmers. The arrangement of plant spacings of sweet corn and cabbage variety is expected to result in higher yields and benefits in intercropping. The field experiment, which had the objective to study the effects of plant spacing of sweet corn and cabbage variety on yields of sweet corn and cabbage in the intercropping system, had been conducted from March to July 2008. The experiment was carried out at the dryland farming area at Candikuning Village, district of Baturiti, Tabanan regency, 1.200 m asl. In the experiment, a randomized complete block design with two factors namely plant spacing of sweet corn (120 cm x40 cm, 180 cm x 40 cm and 240 cm x 40 cm) and variety of cabbage (Green Nova and Summer-Autumn) were used. Plant spacing of cabbage was 60 cm x 40 cm. All treatments were replicated four times. The results of the experiment showed that the effect of interaction between plant spacing of sweet corn and cabbage variety in intercropping was not significant on yields of sweet corn and cabbage. Individually, sweet corn plant spacing of 120 cm x40 cm gave the highest fresh weight of cob without husk (10,91 t ha"'), which was 44.50% and 80.93% respectively higher than the spacing of ! 80 cm x 40 cm and 240 cm x 40 cm. The spacing of 180 cm x 40 cm resulted in not the significantly different fresh weight of cob with husk but gave the highest fresh weight of cabbage heads (56.101 ha'1), which was 27.36% higher than that at sweet corn spacing of 120 cm x 40 cm and was not significantly different from that at 240 cm x 40 cm. Cabbage variety Green Nova gave the highest head (56.101 ha1), which was 14.48% higher than variety Summer-Autumn. Intercropping between cabbage variety Green Nova and Sweet corn at 180 cm x 40 cm spacing resulted in the highest benefit (Rp. 20,488125 t ha'1), which was Rp. 3,335500 higher than the average benefit of cabbage monoculture. The efficiency of land use in intercropping was higher (LER: 1.69) than in monoculture (LER: 1). It is suggested to use cabbage variety Green Nova intercropped with sweet corn at I 80 cm x 40 cm spacing. An experiment studying the effect of cabbage intercropped with sweet corn and other short season vegetables planted after harvesting cabbages is also suggested.

A field experiment was conducted at Bangaun, Lamahi-3, Dang, Nepal to study the effect of GA3 on growth and flowering attributes of African marigold (Tagetes erecta) in Inner Terai of Nepal. The experiment consists of three replications and 8 treatments and laid out in a randomized complete block design- consisting of various concentrations of GA3 viz. 0ppm, 50ppm, 100ppm, 150ppm, 200ppm, 250ppm, 300ppm, and 350ppm. Kolkata local variety of African marigold was tested. The study revealed that among different concentrations of GA3, 300ppm showed the tallest plant height (72.93cm) and the highest basal diameter (1.49cm). Maximum numbers of primary branches (3.11) and the greatest plant spread (32.11cm) were obtained from 250ppm; similarly, maximum numbers of secondary branches (13.80) were recorded in 350ppm. In the case of floral parameters both 100ppm and 350ppm recorded earlier days to 50% flowering (44.00 days each), days for 100% flowering was recorded almost similar in every treatment that sticks around 54 and 55 days, maximum diameter (5.370cm) of flowers were obtained from 50ppm, the greatest fresh weight (6.180g) was recorded in 350ppm, 250ppm showed a maximum number of flower per plant (104.13), similarly, a longer duration of flowering (58 days) was recorded in 300ppm. Among all treatments, the 250ppm level of GA3 was found to be most suitable in terms of production perspective.

Influences of nitrogen (N) rate were evaluated on vegetable amaranth. Amaranthus tricolor, grown at uniform populations over two year. The main objective was to determine an optimum level of N fertilization for successful production in middle Georgia. In 1992 and 1993 accession `RRC 241' was planted in randomized complete block design on June 19 and 23, respectively. Four N rates, equally split were evaluated: 0, 45, 90, and 135 kg ha-1. First of the applications were 18 and 13 days post planting for 1992 and 1993, and again when plants were 5 weeks old. Plants were harvested 48 days after planting with green yield, leaf fresh weight. and stem fresh weight collected in both years and leaf area for 1993. In years 1992 and 1993 green yields were 5.3 and 6.5, 10.7 and 9.0. 13.2 and 12.1, and 13.5 and 14.0 Mg ha-1. respectively for the 0, 45, 90, and 135 rates. In both years vegetative components showed significant regression for all treatments. Vegetative response (R2) for green yield in 1992 and 1993 was quadratic (85%) and linear (73%), leaf fresh weight in both years was cubic (63% and 48%), while stem fresh weight response was linear (29%) and cubic (72%). During 1993 leaf area was linear (58%). Non-significance predominantly occurred between the two higher rates for each year and when combined. indicating that 90 kg N ha-1 should provide optimal production of amaranth for the middle Georgia region.

Abstract: The objective of this work was to evaluate the agro-economic efficiency of immature cowpea-radish intercropping systems in a semiarid environment in Brazil. The experiments were carried out in two cropping seasons, in a randomized complete block design with four replicates. The treatments consisted of a 4x2 factorial arrangement for the combination of four cowpea (Vigna unguiculata) cultivars (BRS Tumucumaque, BRS Cauamé, BRS Guariba, and BRS Itaim) and two radish (Raphanus sativus) cultivars (Crimson Gigante and Zapp). The agro-economic indices - system productivity index (SPI), land equivalent coefficient (LEC), and monetary equivalent ratio (MER) - were obtained using single plots of each cultivar in each block. 'BRS Tumucumaque' and 'BRS Guariba' showed the highest productivity of immature cowpea pods, and 'Crimson Gigante' showed the highest yield of marketable radish roots. The cultivation of either 'BRS Tumucumaque' or 'BRS Guariba' cowpea with 'Crimson Gigante' radish provides a greater agro-economy efficiency and sustainability for immature cowpea-radish intercropping.

The effects of two mycorrhizal species (Glomus versiforme and Glomus intraradix) and a control on the growth of green pepper, Capsicum annuum, and lettuce, Lactuca sativa, seedlings have been evaluated using four types of growing media (Peatwool, Fafard bulk mix. Cornell mix and a compost based mix) and two types of containers, Cell Packs (125 cc volume) and Pro-Trays (65 cc volume) for green pepper and Cell Packs (125 cc volume) and Plug Flats (33 cc volume) for lettuce. The experiments were split plot randomized Complete block design with 6 blocks (lettuce) and 4 blocks (pepper). Seeds were sown directly into the containers of mycorrhizal inoculated media. All treatments received the same fertilizer regime. Cell volume had no significant effects on green pepper fresh weight, dry weight, stem diameter, leaf area or leaf number but the lettuce Cell Pack plants had significantly higher fresh and dry weights, more leaves and higher leaf area. The Fafard Bulk and the Compost mix gave significantly higher fresh and dry weights than did the other two media for both green pepper and lettuce. Mycorrhizal species did not influence plant growth with the exception of leaf area in green peppers and shoot dry weight in lettuce.
