Milk thistle (Silybum marianum (L.) Gaertn) has been used in medicine since ancient times, but it has been cultivated as a medicinal plant only in recent decades. The ripe fruit of milk thistle contains flavonoids, which are used to prepare anti-hepatotoxic drugs. The main purpose of this study was to substantiate the effects of irrigation and row spacing on growth, seed yield and the content of active substances (silybin and silymarin) in milk thistle. The results showed that the suitable amount of irrigation was 20 mm and the appropriate row spacing was 25 cm.

Yield and quality of chestnut (Castanea mollissima) are affected by nitrogen availability; however, there are few reports on foliar and root absorption of different chemical forms of N in chestnut. To analyze the absorption characteristics of exogenous nitrogen fertilizer labeled by 15N in chestnut, nitrate and ammonium nitrogen uptake and allocation were determined in one-year-old seedlings that received soil- and foliar 15NH4NO3 and NH415NO3. We found that 29% of the nitrate and 25% of the ammonium absorbed by the leaves were translocated to the roots, while 62.01% of the nitrate and 63.27% of the ammonium absorbed by the roots were translocated to the shoots. The seedlings absorbed more nitrate nitrogen than ammonium nitrogen and their foliar N uptake was faster than their root uptake. Most of the N absorbed by the seedlings was fixed in the shoots in both foliar and soil uptake. The proportion of N fixed was greater in seedlings subjected to foliar fertilization than in those treated with soil fertilizer. Foliar fertilizer application can meet the N nutritional needs of fast-growing shoots more effectively than soil fertilizer application. However, soil fertilization was a better long-term N source than foliar fertilization. Thus, ensuring an adequate supply of nitrate N fertilizer in the soil accompanied by a commensurate increase in foliar fertilizer application can effectively meet the nutrient requirements associated with the rapid growth of chestnut seedling shoots.

The World

Milk thistle, Silybummarianum (L.)Gaertn.,is grown throughout the world for its hepatoprotectant flavonolignans, known collectively as silymarin. Silymarin is found primarily in the seeds. Milk thistle was grown outdoor field for determination of plant growth, seed yield under various variants of row spacing (30x20, 40x20 and 50x20) and different sowing dates (May 20, May 30 and June 10). Plant height measured (ranging from 43.5-82.6cm)and yield (ranging from 5.24-70.31cg/ha) that there was a significant difference among different sowing dates and row spacing.Mongolian Journal of Agricultural Sciences Vol.13(2) 2014: 73-75

Forage sorghum presents tall plants, what makes mechanicalseed harvesting a difficult task. Plant hormones can reduce plant height andfacilitate the harvesting. Thus, the objective of this study was to evaluatethe effect of the growth regulator trinexapac-ethyl on plant height and seedyield in forage sorghum. This research was carried out at Embrapa Maizeand Sorghum, in two seasons (2017 and 2018), in a randomized completeblock design, four replications and three varieties (BRS Ponta Negra, 1141574and 0947216) under application of Trinexapac-ethyl in two stages of the plantgrowth (V8, V12, V8 + V12). The characteristics evaluated were: plant height,seed yield and mass of 1000 seeds. The effect of the hormone was significantin both stages of growth, with a significant reduction in plant height. Thehormone applied twice at growth stages V8 + V12 had a greater effect inreducing plant height. However, the hormone reduced seed yield in the threevarieties, what implies the need for further studies comparing the advantageof plant height reduction and the loss in seed yield.

Npk Fertilization

Nigellia sativa L. plants were fertilized with different rates of NPK fertilizers and sprayed with the growth regulators BL-2142 at 0, 250, 500, and 1000 ppm, CCC at 0, 500, 1000, and 1500 ppm and Multiprop at 0. 12.5, 25, and 50 ppm. The results indicated that both of NPK fertilization and growth regulator treatments enhanced the plant growth in terms of stem diameter, branch number and herb dry weight. Also, these treatments caused early flowering, increased fruit number and seed yield compared to the control plants. The interaction between NPK fertilization and growth regulators had a synergistic effect. The highest seed yield was obtained when the plants received 200, 100, and 25 kg/feddan (feddan = 4200 sqm) of urea, calcium superphosphate and potassium sulphate, respectively and sprayed with CCC at 500 ppm.
