17. Compensatory Production for Kharif Deficit
In order to compensate for the loss of production during kharif 2009, advance and meticulous planning for rabi and summer crops has become crucial to cover up kharif deficit. Improved technology for rabi including Resource Conservation Technology for enhancing production and profitability of wheat and other rabi crops, promotion of winter maize and improved technology for rabi/ summer rice, particularly for Boro-rice areas will need more focussed attention. Preparations for pre-rabi/ rabi and summer crops will require region specific cropping plans including identification of suitable crops and varieties, supply of seeds and inputs and promotion of improved agronomic, soil and water management practices.
Extra efforts for intensification of agricultural activities in normal and surplus monsoon areas/ States during ongoing kharif and ensuing rabi season for enhancing productivity assumes greater importance to capitalise on good resource base to compensate for the kharif production shortfall in deficit monsoon hit areas of the country.
17.1 Boro Rice
Non-kharif, Boro and summer rice has been cultivated traditionally in water logged, low-lying or medium lands with irrigation during November to May in Eastern India. It is a relatively long duration (six month) crop as compared to kharif season (4-5 months). It, therefore requires more number of irrigations and also being non rainy season period. Fortunately boro rice cultivated areas have reliable ground water resources. Nursery is raised in November and transplanted in January. Boro is a winter season, photo-in sensitive, transplanted rice cultivated on supplemental irrigation. Rapid expansion of boro rice has taken place in recent years in West Bengal and Bihar and is fast expanding to more areas in Bihar, West Bengal, Assam, parts of Eastern U.P., Orissa and Andhra Pradesh. Boro rice in India expanded from1.35 million ha (1991) to 2.95 million ha (2000), and is spreading further. Boro rice has 2-3 times higher productivity (5-6 t/ha) in deep water areas of eastern India against productivity of traditional kharif rice (1.3-2.5 t/ha). Its yield is more on account of better water management, longer duration (165-180 days), more sunshine and least infestation of pests and diseases during boro season.

Boro /summer rice takes advantage of residual moisture after the harvest of kharif rice especially in low lying regions, areas adjoining canal and roads, chaur lands etc. Opportunity for intensification of boro rice cultivation in such areas of Eastern India should be capitalised for enhanced rice production to meet expected shortfall of 2009 kharif rice production. Suitable varieties of Boro/ summer rice for different Eastern States are given in Annexure - 5. In view of limited water availability, the recommended nursery management, land preparation, agronomic and water management practices are given in Annexure - 6.
Intensification of boro/summer rice with improved technology and inputs (water and fertilizer management) in Eastern India will help in obtaining additional rice production. This may also have to be incentivized by supporting low cost polyhouse and/or low plastic tunnels for raising nursery to avoid cold injury to seedlings where temperatures are low. Sprinkler irrigation of main crop may be promoted to effect water saving especially where groundwater is used.
Besides boro/summer rice in Eastern India, intensive cultivation of rice with better management and inputs should be emphasised during NE monsoon period in States like Tamil Nadu to cover up deficit production of kharif rice in north India. Storage position of important reservoirs in Tamil Nadu and Karnataka is also favourable as on today. Appropriate provisions for supply of energy (electrical/diesel) will need to be put in place for lifting water, wherever needed.
17.2 Winter Maize
Karnataka, Andhra Pradesh and Bihar are the three largest maize producing states with 2.72, 2.46 and 1.72 million tons respectively closely followed by Uttar Pradesh and Maharashtra. Cultivation of maize in winter season started in mid 60s in some pockets of Bihar and South India. Yield obtained during this season is invariably higher (>6 t/ha) than the Kharif season yield (2-2.5 t/ha.) due to long duration of growth and least infestation of pests and diseases. In Bihar, maize can be taken up in all the three seasons. In recent years, significant changes have occurred in maize production and utilization due to increasing commercial orientation of this crop and rising demand for diversified end users, especially for feed and industrial uses. A sizable number of districts (110 districts), in the states of Andhra Pradesh, Karnataka, Bihar, Maharashtra, Uttar Pradesh, Madhya Pradesh, West Bengal, Orissa, Gujarat, Chhattisgarh and Tamil Nadu have potential for growing winter maize (Annexure-7). In Bihar alone, there are 18 such districts out of 38 districts.
There is a vast opportunity for intensification of winter maize during flood free period in these and other districts to compensate for the loss during Kharif season with proper planning for seeds, inputs and improved management practices and crop diversification. The medium and uplands where subsistence yield of wheat, rabi rice and other winter crops is obtained, could be substituted by winter maize in Bihar, West Bengal, Eastern UP, Orissa, parts of Jharkhand etc. Maize varieties like Shaktimaan-1,2,3,4, Laxmi, Dewaki, Rajender-1,2, High Starch and Ganga-11 are the recommended varieties for rabi maize in Bihar region. In general, any late maturing single cross-bred variety of Kharif season is equally good for winter season. Winter maize (170-180 days duration) has the clear cut comparative advantages of low incidence of diseases and insect pests, is not affected by temperature rise during winter (as the wheat is) and do not suffer on account of heavy rainfall. Cultivation of maize with zero-tillage drill is also gaining momentum as it can make best use of residual moisture, reduce cost of cultivation and thereby increase profitability.
17.3 Wheat and other Rabi Crops
Timely sowing of wheat and expansion of zero tillage technique to cover more and more areas in the Indo-Gangetic plains of UP and Bihar for enhanced productivity, water and cost saving. In UP and Bihar, zero tillage machines should be promoted at massive scale through providing liberal subsidy for adopting zero tillage. This will advance the sowing of wheat in otherwise traditionally late sown conditions and help achieve higher productivity. The sowing of wheat in States like Haryana and Punjab should preferably be done during 25th October to 25th November under timely sown condition. The old varieties like PBW 343 and PBW 502, which have become susceptible to rust diseases, should be replaced in these States with resistant varieties like DBW 17 and PBW 550 possessing high potential. The situations where harvest of paddy is delayed, the early maturing wheat varieties like PBW 373, WH 1021, PBW 509, DBW 16, UP 2425, Raj 3765, PBW 590 etc. should be sown preferably using zero tillage drill.
17.4 Intensification of Rabi pulses and oil seeds
Concerted efforts may be made in enhancing productivity of pulses in Tal areas of Bihar through better water and fertilizer management. Rice fallow areas in eastern and central India may be targeted for pulses like chickpea, lentil etc. together with moisture conservation measures. In acid soils of eastern region, cultivation of pulses should be promoted with application of lime plus recommended dose of fertilizer for enhancing production and productivity of pulses.

Medium and Long Term Strategy
Medium and long term strategies should aim at creating resilience or robustness by various mitigative measures productively.
