This study was conducted to determine the influence of irrigation levels on spring planted sunflower (Helianthus annuus L.) sown with different planting methods. Sunflower was sown either on 60 cm apart single rows on flat seed-bed or on ridges. Three irrigation treatments were I0 (irrigation at early vegetative stage, at bud visible stage, at anthesis and at achene development stage), I1 (irrigation at early vegetative stage, at bud visible stage and at achene development stage) and I2 (irrigation at early vegetative stage, at bud visible stage and at anthesis stage). In I1, irrigation was missing at anthesis and in I2 irrigation was missing at achene development stage. Sunflower yield and yield components showed positive response to ridge sown sunflower with normal four irrigations. Maximum achene yield 3.33 t ha-1 was recorded in ridge sown sunflower with four irrigations. Oil content percentage was highest in case of I0 (42.25%) while the effect of planting methods on oil content was insignificant.

Water scarcity around the globe and climate change challenges has forced the researchers to develop alternative production systems with higher water use efficiency. Direct seeded rice is the emerging water saving rice production system having higher water use efficiency. Field experiment was conducted to assess the role of different mulch systems in improving water use efficiency and productivity in direct seeded and transplanted rice. Three different rice production systems viz., transplanted rice with continuous flooding, two weeks continuous flooding after transplanting and direct seeding with supplemental irrigation only were evaluated under two ground cover systems i.e., plastic and straw mulching with no mulch taken as control. Super Basmati was used as experimental material. Continuously flooded transplanted rice with plastic mulching resulted in higher paddy yield (4.04 t ha- 1 ); while performance of no mulch direct seeding remained poor in this regard. Two weeks flooded transplanted rice with plastic mulching followed continuous flooding in paddy yield (3.94 t ha- 1 ). Continuously flooded transplanted rice with plastic mulching observed substantial improvement in yield related attributes such as panicle length, number of grains per panicle and 1000 grain weight. Plastic mulching improved the productivity and water use efficiency of transplanted as well as direct seeded rice. Higher water use efficiency was observed in direct seeded rice with plastic mulching as it was grown on supplemental irrigations. In crux productivity and water use efficiency of transplanted and especially direct seeded rice can be improved by using plastic film as mulch in current scenarios of water shortage. Key Words: mulching, rice production systems, water use efficiency, productivity

Plenty of variations in nutritional, morphological and agronomic traits occur in the pigmented rice germplasm. The current study was conducted to evaluate the growth characteristics of 71 pigmented rice genotypes having different origin taking one Korean landrace (Heugjinjubyeo) as control. Amongst the twenty eight growth characters studied; leaf length, leaf width, ligule length, panicle length and panicles per hill showed a higher degree of variance. The heading dates of the pigmented rice germ plasm were distributed from Aug. 1 to Sep. 28. Thirty five cultivars that headed or flowered in August were found adaptable for cultivation in Korea. The mean culm length and panicle length were significantly higher than Heugjinjubyeo but most of cultivars having strong or middle of culm strength made it possible to produce the stable yield. Some cultivars showed unique qualitative characters such as openness of culm angle, purple ligule, auricle, awn and glume colors, poor panicle exsertion and long empty glume. Nine cultivars including Heugjinjubyeo showed purple seed coat color while those of the others (62 cultivars) were of red seed coat.

Sunflower was sown either on 60 cm apart single rows on flat seed-bed or on ridges. Three irrigation treatments were I0 (irrigation at early vegetative stage, at bud visible stage, at anthesis and at achene development stage), I1 (irrigation at early vegetative stage, at bud visible stage and at achene development stage) and I2 (irrigation at early vegetative stage, at bud visible stage and at anthesis stage). In I1, irrigation was missing at anthesis and in I2 irrigation was missing at achene development stage. Sunflower yield and yield components showed positive response to ridge sown sunflower with normal four irrigations. Maximum achene yield 3.33 t ha-1 was recorded in ridge sown sunflower with four irrigations. Oil content percentage was highest in case of I0 (42.25%) while the effect of planting methods on oil content was insignificant.

The present study was conducted to estimate the antioxidant and tyrosianse inhibition activities in different species of Apiaceae family. Total fifteen two species of Apiaceae family were used as experimental material and a great variation amid species for antioxidant and tyrosinase inhibition activities was noted. Methanol extracts of Bupleurum falcatum L. and Torilis japonica D. C. exhibited higher total polyphenol and total flavonoid contents, respectively while Foeniculum vulgare Gaeriner exhibited higher antioxidant and tyrosinase inhibition activities. Nonetheless, species under study exhibited a strong negative correlation between antioxidant activities and total polyphenol and negative correlation between antioxidant activities and total flavonoid contents; whereas non-significant correlation between tyrosinase inhibition activities and total polyphenol and flavonoid contents were noted. Species under study also exhibited a strong positive correlation between total polyphenol and total flavonoid contents whereas non-significant correlation between antioxidant activities and tyrosinase inhibition activities. In conclusion, Foeniculum vulgare was found better due to its higher antioxidant and tyrosinase inhibition activities.

Abstract The present study was conducted to evaluate of the 1,1-Diphenyl-2-Picrylhydrazyl (DPPH) radical scavenging effect, cytotoxicity and tyrosinase inhibition activities using methanol extracts from different parts of four herb plants. The results showed that whole and root extracts of yarrow the highest total polyphenol and flavonoid contents as well as whole of yarrow revealed the highest DPPH radical scavenging effect. In cytotoxicity test against three cancer cell lines, HeLa (uterus), SK-Hep-1 (liver), and YD-15 (oral), the whole extract of feverfew showed the highest toxicity with IC50 values of 102.58-138.68 μg/mL. Also, mallow root extract (71.24 μg/mL) exhibited potent tyrosinase inhibitory activity comparable to arbutin (69.56 μg/mL), which was used as the control.

Significant variations occur in pigmented rice germplasm with respect to their antioxidant potential. Therefore this study was designed to evaluate the antioxidant potential of exotic rice germplasm collected from different parts of the globe. Grain samples of exotic rice germ plasm (21 0 accessions) were collected from different countries of Asia, America and Europe and their ground grain samples were extracted with 80% methanol at 30 oc using sonicater for 30 minutes to estimate their total polyphenol and flavonoids contents and antioxidant activity. Rice germplasm had tremendous variations with respect to total polyphenols (0.0800.71 mg g- 1) and falvonoid contents (0.091 00.413 mg g" 1 ) and antioxidant activity (18096%). Rice cultivars with red and black seed coat had higher antioxidant activity owing to significantly higher polyphenols and falvonoid contents in their grains. Therefore rice cultivars with red and black seed coat color should be included in breeding rice genotypes with higher nutritional value.
