Abstract

A field experiment was conducted to study the impact of chloro choline chloride (CCC) with potassium sulphate and boric acid on growth, physiological traits and yield of little millet under rainfed condition. Combination of CCC (250 ppm) with K₂SO₄ (1%) and boric acid (0.3%) registered highest total chlorophyll content (1.61 mg) and soluble protein content (14.2 mg). The moderate plant height (120.8 cm) and number of leaves (77) recorded by CCC (250 ppm) with K₂SO₄ (1%) and boric acid (0.3%) compared to other treatments. However, the highest plant height of 133.2 cm registered by water sprayed control and lowest plant height of 109.2 cm recorded by foliar spray of 250 ppm CCC. The Highest number of leaves was recorded by control (82.3) and lowest in CCC alone (67.3). Lowest number of days to flowering (44.7) recorded in foliar spray of CCC (250 ppm) followed by CCC (150 ppm). However, these treatments are significantly on par with each other. The crop growth rate increased by the application of CCC and not supported by addition of potassium and boron. CCC 250 ppm with K₂SO₄ and boric acid spray recorded higher grain yield of 897 kg ha^-1 compared to control (783 kg ha^-1).

Keywords: Little millet, CCC, potassium sulphate, CGR, chlorophyll, soluble protein, grain yield.

Abstract 

This study was performed to evaluate the compressive strength of cemented sand and gravel (CSG) material with the Hilti vibrating compaction method and the effects of variables such as curing age and to investigate the planting properties of these CSG blocks when seeded with herbaceous plants and cool-season grasses. Four types of CSG mix designs and cement contents were evaluated by a compressive strength test, and two types of CSG mix designs were tested as planting blocks. To analyze the growth properties of plants in the CSG blocks, the initial germination ratio and period, visual cover and plant height were measured at 4 to 12 weeks after seeding. The results showed that the compressive strength of the CSG material increased as the cement content and curing age was increased. The initial germination started within 5 to 8 days after seeding regardless of the kind of plant or type of CSG block, and the germination ratios were in the range of 55 to 60%. The visual estimation of the cover of the different kinds of plants appeared over eight points for all blocks at eight weeks after planting.

Key words: Hilti vibrating, cemented sand and gravel, planting, germination, cover view.

Abstract

Researchers at Purdue University have developed a device which removes excess heat from sows and helps to mitigate thermal stress. The optimal amount of cooling coil beneath the top pad in the device needed further investigation. A second prototype with eight coolant pipes was compared to the original six-pipe prototype design. Bench tests of thermal and heat transfer properties similar to the initial prototype testing were conducted with instrumented heat exchangers and completed using an animal simulator that could maintain a constant temperature. The results indicated that at steady state operating conditions, the heat rejection (heat transfer rejected through coolant) in the eight-pipe unit was significantly greater than the six-pipe unit, heat exchanger efficiency in the eight-pipe unit was significantly larger than in the six-pipe unit, the effectiveness in the eight-pipe unit was significantly greater than the six-pipe unit, and the conductive heat transfer coefficient was larger than that of the six-pipe unit. Intermittent operation testing showed improvement with increasing off periods in peak heat rejection, average heat rejection, efficiency, and effectiveness. This work demonstrated the superiority of the eight-pipe design over that of the six-pipe design, and further design prototypes have incorporated this additional eight-pipe coil length.

Abstract

The advent of second and third generation DNA sequencing techniqnologies have revolutionized the genomics research. The Single Molecule Sequencing technologies are adequate to minimize occurrence of errors in sequencing. The third generation sequencing technologies could overcome limitations of first and second-generation sequencing technologies. The almost complete human genome sequencing was performed by using single molecular sequencing technologies. Benefits, risks and safeguards associated with the disclosure of information of very intimate kind contained in human genome, were also discussed. The power of whole sequencing for human welfare arises only from associations with medical histories, behavioral characteristics, physical descriptions and genome-environment interactions not from mere knowledge of base pairs.

Key words: DNA sequencing, medical histories, behavioral characteristics, physical descriptions.

Abstract

The aim of the present study was to determine the effect of Plant Growth Regulators (PGRs) viz. Indole-3-acetic acid (IAA), Gibberellic acid (GA₃) and Kinetin in their physiological ranges from 10^-7 to 10^-5 M on tuberous roots of Coleus barbatus (patharchur) with their respective control. The certified seed material was procured from Forest Research Institute (FRI), Dehradun, Uttarakhand (India). Significant variation was reported in growth of tuberous roots of Coleus due to hormonal treatments and out of these three hormones IAA at 10^-5 M was observed highly effective as compared to control, GA₃ and Kinetin. Application of IAA at 10^-5 M, resulted in maximum promotory effect on number of tubers, fresh weight and dry weight, followed by GA₃ at 10^-5 M, Kinetin at 10^-7 M as compared to control. Application of IAA, GA₃ and Kinetin resulted in more number of tubers, which was found increased by c.a. 52, 28 and 16%, respectively as compared to control.

Key words: Coleus barbatus, indole-3- acetic acid, gibberellin, kinetin.

Abstract

Correlation coefficients were determined in fifteen wheat genotypes for plant height, days to heading, days to maturity, 1000-kernel weight, spike length, number of tillers per plant, number of spikelets per spike and grain yield per plant. The result revealed that grain yield per plant was positively and highly significantly correlated with days to maturity but negatively and highly significantly associated with plant height. Days to maturity had highest positive direct effect on yield.
