An experiment was conducted for a period of two years from 1977 to 1979 to study the performance of different cropping systems under gardenland conditions with varying levels of soil fertility. Four cropping systems were raised under three levels of fertility and economics worked out. The results indicated that sorghum + greengram cotton + onion- radish - blackgram gave the highest net income of Rs. 13,100/ha/year followed by ragi - cotton onion sorghum + lablab systems (Rs. 6860/ha/year). Wherever facilities for marketing the vegetable exists, the former can be recommended and in other places the latter can be recommended. There was no difference in yield of crops due to fertilliy levels indicating that by including legumes in the cropping system and with proper residue management, it is possible to save adout 25% of NPK recommended to the crops included in the systems.
