Title : Impact of transplanting dates and shock preventing methods on nutrients concentration in grain and stover and their total uptake by pearl millet cultivars

Abstract :

A field experiment was conducted on loamy sand soil at the Rajasthan Agricultural Research Institute (SKNAU, Jobner), Durgapura, Jaipur, during two consecutive kharif seasons in 2019 and 2020. The investigation consist of two pearl millet varieties (RHB-173 and RHB-177), transplanting shock preventing methods (No treatment, Triacontanol @ 0.25 ml/litre, Triacontanol @ 0.50 ml/litre and Leaf clipping) and three dates of transplanting (15th June–30th June, 1st July–15th July, and 16th July–31st July) were replicated thrice in factorial randomized block design. Results revealed that the nutrients concentration in grain and stover of pearl millet were merely affected by both doses of triacontanol i.e. 0.25 and 0.50 ml/litre and their total uptake altered by all the experimental variables during individual year of study. The pearl millet cultivar RHB-173 recorded significantly higher grain yield over RHB-177. Among the transplanting shock preventing methods, triacontanol @ 0.50 ml/litre observed statically superior in increasing grain yield of pearl millet as compared to no treatment and leaf clipping, but it was found at par with triacontanol @ 0.25 ml/litre during each year of investigation. The crop transplanted during 1st July to 15th July noted significantly higher grain yield over 1st June to 15th June, however it was found at par with later (16th July- 31st July) transplanted crop.
