In the vast expanse of North India, where wheat cultivation is a staple, farmers often grapple with the challenges posed by sub-optimal temperatures during sowing. This can lead to delayed germination, stunted growth, and ultimately, a lower yield of poorer quality grains. However, a groundbreaking study led by Okram Ricky Devi of Assam Agricultural University has shown promising results in mitigating these issues through the use of organic liquid manure, specifically herbal kunapajala (HK).
The study, published in the ‘Emirates Journal of Food and Agriculture,’ delved into the effects of seed priming and foliar application of HK on late-sown wheat. The research, conducted over 2020-21, utilized a randomized block design with 14 different treatments, each combining various levels of HK priming and recommended doses of nutrients (RDN).
One of the standout findings was the significant increase in plant height, grain count per spike, and fertile spikelets per spike in treatments involving HK priming and foliar application. Notably, the treatment combining 25% HK priming with 100% RDN followed by foliar application of 10% HK (T7) showed remarkable results. “The plants were notably taller and produced more grains per spike,” Devi explained, highlighting the treatment’s effectiveness.
The study also revealed that HK priming and foliar application enhanced grain production and harvest index, with T7 and T3 (10% HK priming with 100% RDN and foliar application of 10% HK) yielding the highest grain production. Furthermore, the treatments significantly increased α-amylase activity, a crucial enzyme for grain quality. Devi emphasized, “This shows that HK not only boosts yield but also improves grain quality, which is a game-changer for farmers.”
The commercial implications of this research are vast. By improving crop yield and quality under late-sown conditions, HK priming and foliar application can help farmers mitigate the risks associated with delayed sowing. This is particularly relevant in the context of climate change, where unpredictable weather patterns are becoming more common. As Devi noted, “HK is a cost-effective and sustainable method that can enhance crop production and economic profitability, especially in challenging conditions.”
This research paves the way for future developments in agritech, particularly in the use of organic liquid manures for crop enhancement. As we move towards more sustainable agricultural practices, the findings from this study offer a promising avenue for improving crop resilience and productivity. The use of HK as a seed priming agent and foliar spray could revolutionize wheat cultivation in North India and beyond, offering farmers a reliable tool to combat the challenges posed by sub-optimal sowing conditions.
