Abstract
A study entitled “Effect of Integrated Nutrient Management and seed priming on nutrient uptake and yield of finger millet (Eleusine coracana)”was conducted under field condition at the experimental plots of DKS farm, IGKV, Bhatapara Dist- Baloda Bazaar, Chhattisgarh during kharif season of the year 2019. The soil of the experimental field was Alfisols and climate was sub-humid with a total rainfall of 872.2 mm during the crop growth.“The objectives of the study were “to study the effect of ”integrated nutrient management and seed priming on growth, yield, quality parameters and nutrient content of finger millet” and to study the physico-chemical and micro-biological properties of soil as influenced by various treatments. The treatments constituted with five nutrient management N1 (Control), N2 (125 kg Neem cake + 1.25 tons ha-1 vermicompost), N3 ( 50 “kg/ha N : 50 kg/ha P2O5 : 50 kg /ha K2O”and 2% Borax spray at flowering), N4 (125 kg Neem cake + 1.25 tons ha-1 vermicompost + 50 kg/ha N : “50 kg/ha P2O5 : 50 kg/ha K2O and” 2% Borax spray at flowering) and N5 (Recommended “dose of fertilizer i.e. 20 kg/ha N”: 20 kg/ha P2O5 : 10 kg /ha K2O) with four priming treatments P1 (Control), P2 (Hydro priming for 6 hrs) P3 (Seed priming with 2% KH2PO4 for 6 hrs) and P4(Seed priming with 20% liquid Pseudomonas fluorescens).
Results revealed that all the physico-chemical properties except pH and EC of post harvest soil were enhanced in integrated nutrient management. The highest OC%, higher level of plant available macronutrients and micronutrients and higher microbial population was found in N4 treatment. Results also revealed that all the growth parameters of finger millet were enhanced by integrated nutrient management and the highest value of field emergence, plant height at 45DAS, 60DAS and plant height at harvest, number of effective tillers/plant and DAS 1st flowering and 50% flowering were found higher in N4 treatment. The effect of seed priming was seen only in early days of plant growth for P3 and P4 treatments, which were latter masked by environmental factors and no interaction effect was seen during complete growth period of finger millet.
Although effect of integrated nutrient management was non-significant for all the essential macronutrient and cationic micronutrient content in grain and straw of finger millet, however enhanced uptake was found in N4 treatment for all the nutrient due to better growth and yield parameters of finger millet crop, which resulted in higher dry mass production of the crop.
Due to addition of neem cake and vermicompost along with inorganic fertilizers better physical, chemical and biological soil condition was provided to the plant which results in better crop growth and yield parameter of plant and ultimately, the yield of finger millet was increased through integrated nutrient management practices.
