India is the largest producer, consumer and importer of oilseeds in the world. Oilseeds are mostly grown with rainfed conditions in marginal to sub-marginal lands. Total production of oilseeds is 31 million tons. Our demand outstrips domestic production, resultantly, importing oil becomes an annual feature in India. Out of total vegetable oil demand of 24 million tons, 14-15 million ton oil is imported and we could produce only 9-10 million tons. But success of oilseeds production is largely dependent upon the monsoon climate. In this backdrop, I am tossing up following issues to be addressed with probable solutions/ interventions for strategizing the production and productivity of oilseeds:
  • How can development and adoption of drought tolerant varieties come as rescue to the existing problem of oilseeds?
  • How can the production of oilseeds be sustained under moisture limiting/excess conditions, since crop is predominantly raised under rainfed conditions?. How can we safeguard the standing oilseed crop in field through supplemental irrigation ?.
  • Why have the past attempts on adoption of resource conservation techniques such as raised- bed planting, drip irrigation and mulching , been failing so consistently?.
  • Whether, you foresee a better promise with growing two or more crops together from farmers income perspective and standout against fragility of rainfed farming.
  • What promise, the application of micronutrients and biofertilizers hold in the entire gamut of management strategies in production of oilseeds?
  • What are the other secondary sources which could be tapped for supplementing huge demand.
  • Can we become self sufficient in oil seeds production and what should be the strategy to reduce import?
I shall regard your responses.

Production of oilseed crops are decreased with the fast rate of drought stress. So how to reduce the drought stress in pulsed.
Relevant answer
Answer
Thiourea spray @ 500 ppm at pre-flowering and pod development stages are known to reduces moisture stress in oilseed crops and enhances oil content. Moreover, spray of anti-transpirants and use of recommended K fertilizer doses also helps to minimize the drought effects.

Dear all,
I am trying to select the transgenic Camelina sativa lines on Hygromycin B. The published literature are reporting multiple concentration for Hyg B selection, however most of them says 5mg/L of Hyg in half strength MS. I want to get in touch with some who has optimized the selection concentration by experiment.

Answer
Asked this question a month ago, In between I did MIC optimization for Camelina seeds. Results are attached if someone come here digging the question.

As we know, sunflower (Helianthus annus) is an oilseed crop and is not often practiced for heavy metal phytoremediation. Commonly, chines brake, pteris vittata are used as hyperaccumulators in countries like in china. In pakistan, which plant is best to be used as hyperaccumulator other than pteris vittata?
