SUMMARY
A field experiment on sorghum was conducted during kharif season of 2021, 2022 and 2023 and fenugreek during rabi season of 2021-22, 2022-23 and 2023-24 to study the effect of nutrient on yield of sorghum-fenugreek cropping sequence at Centre for Millets Research, Sardarkrushinagar Dantiwada Agricultural University, Deesa. The experiment was carried out in randomized block design with four replications comprising seven treatments. Sorghum under rain-fed environment of North Gujarat with following kharif sorghum-rabi fenugreek cropping sequence was applied 60 kg N/ha and 40 kg P2O5/ha to sorghum and 20 N/ha and 40 kg P2O5/ha to fenugreek crop along with 1% solution of multi-micronutrient grade IV (Fe-4.0%, Mn-1.0%, Zn-6.0%, Cu-0.5%, B-0.5%) to both the crops at 30, 45 and 60 DAS for getting higher sorghum equivalent yield and net profit. Results showed that significantly higher organic carbon (0.30 %) was recorded under treatment RDF (60 + 40 kg NP/ha). DTPA extractable Fe (3.03 ppm) and DTPA extractable Zn of soil (1.62 ppm) was observed under treatment RDF + Soil application of micronutrient as per STV while DTPA extractable Mn and DTPA extractable Cu of soil was not significantly influenced by different treatments. Fe, Mn and Zn content and uptake by fenugreek crop was not significantly influenced by different treatments. Fe, Mn, Zn and Cu uptake by plants was recorded higher under treatment RDF + Foliar spray of 1 % multi micronutrient Grade I at 30, 45 and 60 DAS). Fe, Mn and Zn content and uptake in grain was recorded significantly higher under treatment T7 while Cu content in grain was significantly higher under treatment RDF + Foliar spray of 1 % multi micronutrient Grade IV at 30, 45 and 60 DAS while Cu uptake by grain was not significantly influenced by different treatments but highest under treatment RDF + Soil application multi micronutrient Grade V (20 kg/ha).
