  Mode of gene action was studied in a 5 x 5 diallel cross of bread wheat involving five genotypes namely 8073, 8177, 6039-4, Pb-96 and MH-97. Highly significant differences were observed for all the traits studied. Over-dominance was observed in hygrophilic colloids and stomata size. Flag leaf area, leaf venation and stomatal frequency were governed by partial dominance with additive gene action. Epidermal cell size was controlled by partial dominance. Non-allelic interactions were observed in flag leaf area and stomata size.

  Competition functions of different intercropping systems i.e. canola, wheat gram, lentil and linseed were compared with sole cropping of canola for two consecutive years under the field conditions. Competition behaviour of component crops across different intercropping systems and planting patterns was determined in terms of relative crowding coefficient, aggressivity and competitive ratio. Relative crowding coefficient (RCC) reflected that maximum K (4.08) was obtained from canola+one row of wheat intercropping system. Aggressivity (A) values –0.03 and 0.06 indicated that wheat was the most competitive crop to canola. Similarly, competitive ratio (CR) 0.82 and 0.51 showed that among intercrops, wheat proved to be a better competitor than other intercrops when grown in association with canola.

  The experiment was conducted in greenhouse and field under moisture stress condition using twenty four spring wheat genotypes. Inter-relationship among different characters were estimated by simple correlation and path-coefficient analysis. Simple correlation indicated that survival rate, root/shoot ratio, root density, number of veins, flag leaf area, plant height, number of tillers per plant and 1000-grain weight showed positive and significant association with grain yield. Whereas, path-coefficient analysis revealed that 1000-grain weight, root density and stomatal frequency, are the characters which exerted maximum direct positive effect on yield, respectively.

  Agro-economic advantages of different intercropping systems i.e. canola+one row of wheat, canola+two rows of wheat, canola+one row of gram, canola+two rows of gram, canola+one row of lentil, canola+two rows of lentil, canola+one row of linseed and canola+two rows of linseed were compared with sole cropping of canola for two consecutive years under field conditions. Canola seed yield equivalent, land equivalent ratio, area-time equivalent ratio and net income values of canola+one row of wheat intercropping system was higher than the other intercropping systems and sole cropping of canola.

  Response of mungbean (Vigna radiata L.) cultivar NM-98 to seed inoculation and different levels of fertilizer (0-0, 15-30, 30-60 and 45-90 kg N-P2O5 ha-1) was studied under field conditions. Number of pod bearing branches plant-1, number of seed pod-1, 1000-seed weight, seed yield and protein contents were affected significantly by seed inoculation. The application of fertilizer significantly increased the seed yield and maximum seed yield was obtained when 30-60 kg N-P2O5 ha-1 was applied. This increase in seed yield was mainly due to more number of pod bearing branches plant-1, number of seed pod-1 and 1000-seed weight. Seed protein contents were also increased significantly by seed inoculation and fertilizer application. Based on the present findings it can be concluded that mungbean cultivar NM-98 should sown after seed inoculation and given 30-60 kg N-P2O5 ha-1 for obtaining higher seed yield.

  The urban poor, residing in slum and squatter settlements place a high priority on gaining access to basic services for improving their quality of life. The study aimed to explore possibilities for providing green spaces to the people living in these areas. A survey was conducted to study potential role of green spaces in daily life of the people and ascribed health and social benefits. Sixty eight percent respondents reported health benefits, those perceived psychological benefits were 42% and social benefits entailed by 40%. Seventy eight percent pledged to participate in the development of green spaces in the form of cash, provision of labor and supervision.

  The Direct Thermal Analysis (DTA) chromatograms of different rice varieties/mutant revealed 17 components for Basmati-370, Basrnati-198, Kashmir Basmati and DM-25 and 16 components for NIAB-IRRI-9 on SE-30 packed column. The genetic relationship between Basmati -198, Kashmir Basmati and DM-25 and their parent Basmati-370 appeared to be reflected in the composition of their volatiles. A peak of rice aroma, found at retention time 10.84 min. in Basmati-370, Basmati-198, Kashmir Basmati and DM-25 (aromatic varieties/mutant) was absent in NIAB-IRRI-9 (nonaromatic variety) which was supposed by sensory evaluation of the column effluent.
