Recommendations submitted by Dr.H.S.Sen in the second year (April, 2014) as a Member of RAC_DOR on Crop Production & AKMU

Salient research recommendations on Crop Production & AKMU (HSSen)
1.. Large proportion of oilseed grown areas are marginal lands having poor natural resource base especially with respect to soil moisture availability under normal circumstances. .Besides, El Nino might have adverse influence on rainfall distribution leading to more of drought and flood occurrence across India in the ensuing year. Probability analysis on drought occurrence may preferably be worked out using the rainfall and other parameters  of the past nearly 30 years as well as the climate change models for planning for short & long term droughts to occur in future. This warrants a strong need for more attention in the ensuing year on studies on droughts due to climatic reasons. Besides, salinity may also come up to a greater degree in certain areas.
2. Following steps are suggested to obviate the moisture & salinity stress particularly at critical growth stages.
   (a) identify the critical growth stages for a few oilseed crops and study their physiological tolerance mechanism  under the prevailing climatic situations
   (b) it is important to study rhizosphere-moisture interactions genotype-wise, the role of microbial consortia, and their effects on nutrient dynamics.
   (c) along with crop phenology it is also important to study the root characteristics of the sress tolerant genotypes
   (d) it should be of fundamental interest to work out irrigation/water requirement and suggest irrigation strategies to minimize irrigation requirement. The study should also take into consideration the available water resource and water quality with minimum stress on underground water sources.
   (e) conservation tillage practices with zero tillage may be standardized particularly useful for areas having drought situations in order to conserve soil moisture and minimize irrigation requirement.
3.  An exercise may be undertaken to map location-wise suitability of growing different mandated oilseed crops depending on the prevailing agroclimates and market demand/access.
4.  Soil health mapping should be done for all areas suitable for oilseed crops, and suggest cropping systems along with cultural practices in order to arrest or reverse the declining trend of productivity observed at present.
5.  For soil health evaluation it is necessary that the methodologies for soil physical, biological and chemical properties, particularly the former two, be standardized first. This will necessitate discussion with ICAR institutes like IISS, CRIDA, etc. for uniform techniques as well as the approach towards soil health evaluation .
6. Steps should be undertaken to explore the value addition of different oils and their derivatives. Instead of competing with major crops like mustard and groundnut, value addition in respect of minor oilseed crops should be explored in consultation with the concerned  industries.
7. Efforts should be made to work out cropping system(s) location-wise involving the suitable oilseed crops for the areas with the aim to achieve higher harvest index.
8. Attention may also be given for Integrated Farming System research with allied farming activities  to ensure higher and sustainable return to the farming communities. 
9. It is a welcome approach to implement or advance our knowledge on AKMU. It is suggested inthis respect to get in touch with BCKV (attention: Pro-VC) who has developed an effective protocol, which has earned international recognition of late.
