Fourteen cotton genotypes were evaluated during 1990-91 for physiological parameters and yield attributes for higher productivity under rainfed condition. Productivity of high yielding genotypes was associated with low leaf area, high total dry matter, higher leaf efficiency, higher harvest index and boll number per plant. Among the high leaf area genotypes, Allepox Rex was identified as the best performer.

Annual growth rates in production and productivity of the crops were found positively significant however, the rate of increase in the yield of groundnut was relatively less. Higher variability in area, production and yield was observed in case of castor crops. Human labour, bullock labour, manures and chemical fertilizers were the main items of operating cost in all the crops, moreover, seed played important role in the total cost of groundnut cultivation and irrigation charges had greater effect on the cost of cultivation of castor crop. Castor crop was found more remunerative to growers as compared to other oilseed crops under study
