The present study explored the relationship between perceived organizational justice, job satisfaction and organization commitment using a field sample. Sample for the present study consisted of 128 employees working in medical college. Regression analysis of the data obtained indicated that distributive justice was significantly related to job satisfaction whereas procedural justice was not found to be related significantly with job satisfaction. Also both distributive justice and procedural justice were found to be significantly related to organization commitment. Theoretical and practical implications of the results are discussed.

The aim of the present study is to explore the linkages between personality and organization citizenship behavior (OCB) using a field sample. Big-Five personality model was used to explore the relationship between personality and OCB. The participants in the study were 187 doctors working in medical college in north India. Four of the 'big five' factors except Neuroticism were positively correlated with OCB. Hierarchical regression analysis on data after controlling for demographic variables indicated that, Conscientiousness, Extraversion, Agreeableness and Neuroticism were valid predictors for OCB. However, Openness to experience showed no significant relationship with overall measure of OCB. Theoretical and practical implications of the study are discussed.

Wheat (Triticum aestivum L.) being grown with association of boundary plantations of poplar (Populus deltoides M.) has to face competition for water and nutrients uptake. Field experiment was carried to study the dry matter accumulation pattern and nutrients uptake by wheat grown in association with boundary plantations of three-and four-year-old poplar plants under irrigated condition. Dry matter accumulation of wheat declined considerably due to presence of poplar tree line during all the growth stages as compared to pure crop. Maximum reduction in dry matter accumulation in wheat was observed near the tree line (0-3 m) under both three-as well as four-year-old plantation (21.1 and 17.8 per cent under three-and four-year-old trees, resp.) which tapered off beyond that, but synergetic effect caused by existence of trees increased dry matter significantly between 3-6 m distance and 6-9 m distance under both three-as well as four-year-old plantation. Similarly, minimum concentration of nutrients (nitrogen, phosphorus, and potassium) as well as their uptake in wheat plants was observed near the tree line (0-3 m) and increased subsequently with increase in distance from tree line.
