    Physiological studies on the effect of salinity on germination and early growth in Gossypium hirsutum L. and Gossypium arboreum L.
    (CCSHAU, 2011) Kavita; Promila Kumari
    The present investigation was aimed on “Physiological studies on the effect of salinity on germination and early growth in Gossypium hirsutum L. and Gossypium arboreum L.” using various physiological parameters. Six cultivars of cotton (RCH-134, Bio-6488, H-1236, HHH-223, HD-123, AAH-1) were grown in screen house having four salinity levels as control, 4, 8, and 12 dSm-1. Results revealed that with progressive increase in salinity levels the seed germination, vigour index, relative water content of leaves, osmotic potential and stomatal conductance transpiration rate, as well as K+ content of leaves. Maximum reduction in seed germination was recorded in desi cotton cultivar HD-123 at highest level (12dSm-1) of salinity. A progressive increase in salinity levels on the other hand caused catalase, peroxidase activity and Na+ content of leaves enhanced. The maximum enhancement in catalase and peroxidase activity in leaf was observed in Bt. cultivars at both the sampling stages i.e at 30 and 60 DAS. Accumulation of Na+ content in leaves was maximum in desi cultivars HD-123 followed by American. Sodium content of leaves of all the cultivars of cotton increased with increasing salinity level; increase being found to highest in leaves of desi cotton cultivars. Potassium content of all cotton cultivars showed decreasing trend with increasing salinity levels. K+/Na+ ratio of leaves of all cultivars also decreased with increasing salinity level; decrease being highest in Bt. cultivars and minimum was recorded in desi cotton cultivars AAH-1. On the basis of the observations taken in the score-card it was found that Bt. cotton cultivars RCH-134 and Bio-6488 was tolerant to salinity. Both Bt. cotton cultivars (RCH-134 and Bio-6488) showed maximum no of polypeptide bands i.e 14 in SDS-PAGE, while American showed total number of thirteen polypeptide bands while desi cultivars had twelve in AAH-1 and fourteen in HD-123. Result revealed that with the progressive increase in salinity level from 4 to 12 Dsm-1 there was decrease in various physiological parameter enhanced viz; On the other hand, with the increase salinity levels increase in catalase, peroxidase enzymes and the Na+ content was recorded.

    Adaptation of Canvas Embroidery Motifs for Fabric Painting
    (CCSHAU, 2016) Kavita; Vivek Singh
    The present study was conducted in Hisar district of Haryana state to explore the possibility of adaptation of canvas embroidery motifs for fabric painting. Forty five canvas embroidery motifs were collected personally from secondary sources like books, journals, and internet. The collected motifs were screened and categorized as geometrical, floral, and animal & bird motifs by advisory committee keeping in mind their suitability for fabric painting on kurti. These three categories included ten motifs each. These motifs were assessed by experts for their selection. Top ranked three motifs in each category were selected by experts for further research work. Maximum number of collected motifs were geometrical motifs followed by floral motifs. A total of forty five designs were created using nine selected motifs with the help of CorelDRAW software. Top ranked four designs were selected by experts by using a preferential choice index for design placements and colour ways. A total of eight kurti, four embroidered and four fabric painted were developed as per the selected designs, their placements and colour ways. Developed kurti were assessed by thirty consumers for their acceptability level on various parameters. Design number 4 and 44 were highly acceptable designs while design number 29 and 30 were acceptable designs. Created designs and fabric painting technique were highly acceptable parameters while design placement, colour ways and embroidery technique were acceptable parameters of all the designs by consumers. In terms of overall appearance, painted kurti of design number 4 was ranked Ist followed by embroidered kurti of same design ranked IInd and painted kurti of design number 44 got IIIrd rank. Cost of all the developed kurti was considered ‘appropriate but comparatively more number of consumers rated the cost of fabric painted kurti as ‘appropriate’. Consumers had high opinion about all the designs of developed embroidered and painted kurti except one painted kurti of design number 30 (2.32) as they strongly agreed with all the opinion statements with average scores ranging between 2.34 to 2.55. Experts had high opinion regarding adaptation of canvas embroidery motifs for fabric painting as they strongly opined that fabric painting was time saving and cost effective surface embellishment technique as per market trend. It was easy in execution and has effectively replicated the effect of canvas embroidery to maintain its beauty with WMS ranging between 2.34- 3.00. Thus, transformation of innovative designs of canvas embroidery into fabric painting has enhanced the range of designing and productivity.

    Impact of government intervention on sugar prices in India: An economic analysis
    (CCSHAU, 2015) Kavita; Grover, R.K.
    The study on “Impact of government intervention on sugar prices in India: An economic analysis” was done with the following objectives: (1)To analyze the trends in trade and prices of sugar (2)To study the impact of pricing policy on domestic prices of sugar (3)To suggest measures to stabilize the sugar prices. The present study is based on secondary data collected from the various published and unpublished sources, viz. various issues of Cooperative Sugar, Indian Sugar, Published by Indian Sugar Mills Association, Statistical Abstract in India, Indian Agriculture in Brief and Agriculture Prices in India etc. Data on various aspects including domestic prices of sugar, production of sugar and sugarcane, prices of sugarcane, consumption of sugar, stocks of sugar, quantity of sugar exported and sugar imported for the period 1947-48 to 2013-14 were collected. To determine the trends in trade and prices of sugar, linear growth rates were calculated by fitting linear equation using data on prices, export and import. Multiple regression function was used to ascertain the impact of pricing policy on domestic prices of sugar. The coefficient of variation were 30.22, 35.39, 42.53, and 105.89 per cent during period-I, period-II, period-III and period-IV, respectively indicating that stability in the sugar prices was maximum during period-I. Linear growth rates were calculated to be 5.16, 4.98, 4.80 and 4.71 during period-III, period-I, period-IV and period-II respectively. The coefficients of variation and linear growth rates of sugar export from India during selected periods was calculated to be 176.18 per cent, 144.02 per cent, 141.03 per cent and 89.95 per cent during period-IV, period-I, period-III and period-II respectively indicating that the variability was maximum during period-IV. The linear growth rate was reported maximum during period-I followed by 13.78 per cent per annum, 5.20 per cent per annum and -1.56 per cent per annum during period-III, period-IV, and period-II. Positive linear growth rates in imports were observed for all the four periods under study except for period-I where the imports were found to decline at an annual growth rate of 9.55 per cent per annum. The increased sugar production had a negative impact on price of sugar. Positive and significant impact of sugarcane price was observed for all periods under study.
