    Relationship of family environment and school environment with educational anxiety of adolescents
    (Punjab Agricultural University, Ludhiana, 2018) Gurpreet Kaur; Chawla, Asha
    The present study entitled “Relationship of family environment and school environment with educational anxiety of adolescents”. The study was carried out in Government rural and urban schools of Ludhiana district. The total sample comprised 200 adolescents (100 rural and 100 urban) in the age group of 17-18 years. Personal information sheet, Educational Anxiety Inventory (Sood and Anand 2012), Family Environment Scale (Bhatia and Chadha 1993) and School Environment Scale (Misra 2012) were used to collect the data. The findings of the study revealed that more number of females experienced educational anxiety at average level than males. Rural adolescents had more educational anxiety as compared to urban adolescents. Majority of the adolescents (male and female) experienced their family environment at average level. Majority of urban adolescents experienced their family environment at average level than rural adolescents. Males perceived high level in all the dimensions of school environment. Significant locale differences were found in case of permissiveness and rejection only. In case of females correlation analysis between family environment and educational anxiety was found to be significant and inversely associated with educational anxiety except in one dimension i.e conflict, whereas in males correlation was significant and inverse in active- recreational dimension only. Rural adolescents presented significant but inverse relationship of family environment with educational anxiety except in two dimension i.e organization and conflict. Among males correlation analysis between school environment and educational anxiety were found to be non significant apart from one dimension i.e cognitive encouragement and in case of females correlation analysis were found to be significant and inversely associated with educational anxiety and dimensions like creative stimulation and acceptance. Non significant correlation was found in the dimensions of school environment apart from two dimensions i.e creative stimulation and acceptance in case of rural adolescents. Correlation analysis among urban adolescents presented significant and inverse association between educational anxiety and dimensions like creative stimulation, cognitive encouragement and acceptance.

    Raising summer season vegetable crops through intercropping in broccoli (Brassica oleracea L. var. italica) using different doses of nitrogen
    (Punjab Agricultural University, Ludhiana, 2018) Gurpreet Kaur; Sharma, Madhu
    The present research work entitled, “Raising summer season vegetable crops through intercropping in broccoli (Brassica oleracea L. var. italica) using different doses of nitrogen” was accomplished in 2017 at Vegetable Seed Production Farm, Department of Vegetable Science, Punjab Agricultural University, Ludhiana. The experiment was replicated thrice in randomized complete block design (RCBD Factorial) comprising of 3 doses of nitrogen (N1 @125 kg/ha, N2 @ 150 kg/ha and N3 @ 175 kg/ha) and 9 different intercropping systems (T1-Sole Broccoli, T2-Broccoli + Tomato, T3-Broccoli + Capsicum, T4-Broccoli + Chilli, T5- Broccoli + Cucumber, T6-Sole Tomato, T7-Sole Capsicum, T8-Sole Chilli and T9-Sole Cucumber). All the growth, yield and quality parameters of broccoli and intercrops were significantly influenced by nitrogen doses. In case of broccoli, plant height, number of leaves per plant, leaf size, plant spread, height up to head, head diameter and weight, total yield, dry matter content, glucosinolates and nitrogen in leaves were highest in N3 and were statistically at par with N2. In different intercropping systems, N3 recorded the maximum value of growth and yield parameters followed by N2. N1 recorded the highest vitamin C. Among the intercrops, tomato plants showed the highest survival percentage and also recorded the highest gross returns, net returns and benefit cost ratio (BCR) followed by chilli. Land equivalent ratio (LER) was also significantly higher in broccoli + tomato. Based upon the present findings, it is concluded that growing broccoli + tomato/chilli using N2 (150 kg/ha) is a highly remunerative option for Punjab farmers in Rabi season.

    CHARACTERIZATION OF Ustilago segetum (Pers.) Roussel tritici Jensen CAUSING LOOSE SMUT OF WHEAT
    (Punjab Agricultural University, Ludhiana, 2010) Gurpreet Kaur
    Thirty five isolates of the Ustilago segetum (Pers.) Roussel tritici Jensen were characterized on the basis of pathogenicity using Nielsen’s Canadian differential set and other cultivated wheat varieties. The isolates could fall in 6 and 23 categories on the individual basis of their reaction on Canadian differentials and cultivated wheat varieties, respectively. However, 35 isolates could fall into 29 groups on the basis of their reaction collectively on Canadian differential set and cultivated wheat varieties. Grouping of races in most of the cases could not be attributed to the area from where they were collected and also the type of wheat from which initially collected. Only some of the isolates, LS11, LS13, LS16, LS18, LS32 and LS35 collected from Triticum aestivum from Himachal Pradesh, Uttar Pradesh, Dhaulakuan, Rajasthan, Jalandhar and Ludhiana (from Triticosecale) fell in different individual groups indicating geographical diversity in the pathogen. Random Amplified Polymorphic DNA (RAPD) and Inter Simple Sequence Repeats (ISSR) profiling were evaluated for assessing the extent of genetic variation among the isolates of Ustilago segetum (Pers.) Roussel tritici Jensen which causes loose smut disease of wheat. Eight random decamer primers and eight ISSR primers were used to characterize twenty four isolates of the pathogen. These isolates were collected from wheat cultivars grown at various locations of North-Western India (Punjab, Haryana, U.P. and Rajasthan). The RAPD and ISSR primers generated a total of 206 scorable bands collectively. All the isolates could be precisely differentiated from each other employing these primers and initially grouped into two distinct clusters. The molecular classification did not correspond with the geographical distribution, host origin of the isolates and groups categorized based on pathogenicity test. ISSR profiling was found superior to RAPD and can be effectively utilized for further characterization of the loose smut pathogen.
