an area of about 159.22 million hectares with 465.81 million tonnes of production and productivity of 4.36metric tonnes per hectare (USDA, 2013). The major rice producing countries are China,

The possibility of increasing the cropping intensity in Khordha district was assessed by block-wise characterisation of rainfall, soil texture, available water holding capacity of soil and district level temperature during the rice fallow period as well as deciding the appropriate sowing window for both kharif and rabi crops. More than 50% chances of occurrence of wet weeks at the beginning of the kharif season (20-22 SMW) indicated that the summer ploughing and initial seed bed preparation could be taken up during the period followed by sowing of rice from 23 SMW. The 42-43 SMW with greater than 30% initial probability of wet week at 20 mm threshold limit. Considering the length of growing period (LGP) available, the adjustment of rice variety duration by 10-15 days in medium land and advancement of pulse sowing almost by 15 days before harvest of the rice crop (Pira crop) in low land was registered as the best su  suitable option for rabi pulses to ensure better utilisation of rice fallow. In addition to these, harvesting surplus water during kharif and storing in farm ponds for judicious utilisation during rabi season further enhanced the possibility of utilisation of rice fallow and increasing the cropping intensity. In the event of delayed monsoon the rice duration has to be adjusted accordingly not to sacrifice the designated suitable period for rabi pulses.

A field experiment was carried out at Regional Research and Technology Transfer Station (OUAT), Semiliguda of Koraput district under Eastern Ghat High Land zone of Odisha in acidic soil during two consecutive rabi seasons of 2016-17 and 2017-18 to study the residual effect of integrated nutrient management in maize on succeeding toria crop. The experiment was laid out in randomized block design with three replications consisting of twelve treatments. The present investigation revealed that application of soil test based fertilizer with green leaf manure (cowpea), FYM @ 5 t ha-1 and biofertilizer (Azotobacter + Azospirillum + PSB @ 4 kg ha-1 each) to maize crop registered maximum residual effect thereby resulted significantly highest seed yield (6.3 q ha-1) and stover yield (11.1 q ha-1) of toria with a net monetary return of Rs. 7025 ha-1 and benefit cost ratio of 1.38.
