A field experiment consisted of 24 treatment combinations of three levels of phosphorus(0, 20, 40 kg ha-1) and three levels of sulphur (0, 20, 40 kg ha-1) and two level of biofertilizer in form of Rhizobium inoculation (inoculated and uninoculated) was conducted with four consecutive years from 2007-08 to 2010-11 were tested with three replications effect of under factorial Randomized Block Design at Bhachau-Kachchh to study the effect of P, S and Rhizobium on productivity and fertility of soil after harvest of moongbean. The soil of the experiment field was sand loamy with alkaline in reaction, low in nitrogen, sulphur and zinc, medium in phosphorus and potassium. Application of 40 kg P ha-1 and 40 kg S ha-1 along with Rhizobium inoculation significantly increased the productivity of moongbean and improved the nutrient availability of soil at harvest of crop over the control. Maximum economic benefits of gross realization, net realization along with highest BCR of 6.73:1 under the treatment combination P 2 S 2 R 1 .

A field experiment consisting of 24 treatment combinations of four levels of sulphur (0, 20, 40, 60 kg/ha) and three levels of Zinc (0, 2.5 and 5.0kg Zn/ha) and two level of FYM (0 and10 t FYM/ha) was conducted with two consecutive years from 2007-08 and 2008-09 with three replications under Factorial Randomized Block Design at Bhachau-Kachchh to study the effect of S and Zn with and without FYM on yield and yield attributes of mustard. Application of 60kg S/ha and 5.0kg Zn/ha along with 10t FYM/ha significantly increased the yield attributes and yield of mustard as compared to control but it was at par with the application of 40kg S/ ha and 5.0kg Zn/ha along with 10t FYM/ha and maximum economic benefits of gross realization, net realization along with highest BCR of 4.84:1.

A field experiment was carried out on effect of different modules on yield, nutrient uptake and physico-chemical properties of soil after harvest of cluster bean (Cyamopsis tetragonoloba L.) at Regional Research Station, SDAU, Bhachau, Kachchh under Randomized Block Design. The experiment was consisting of five different modules among three are organic modules, one chemical module and control. The results of the experiments are differed significantly. The significant improvement in yield was recorded with the chemical module T 4. In organic modules T 2 and T 3 recorded the more yield as compared to control. Modules T 2 and T 3 also recorded the good nutrient content and uptake. Available nutrients in the soil after harvest are best in the organic modules T 2 and T 3 .
