Effect of Organic Management of Nutrients and Bio-Stimulants on Growth and Yield Attributes of Wheat (Triticum aestivum L.)

A field experiment was conducted at organic farming unit of Agronomy Farm, Rajasthan, College of Agriculture, MPUAT, Udaipur, Rajasthan during rabi 2021-22 to study the influence of different levels of organic management of nutrients and bio-stimulants on growth and yield attributes of wheat grown under organic farming. All the organic management of nutrient treatments resulted in significant increase in plant height and dry matter accumulation at different growth stages of wheat crop. The significantly maximum values of yield attributes viz., effective tillers meter-1 row length, spikelets ear-1, grains ear-1 and grain weight ear-1, were higher under the effect of 100% RDN through 1/3 FYM+ 1/3 Vermicompost + 1/3 Neem cake over 75% RDN, 50% RDN and control. However, application of 100% RDN failed to exhibit significant variation in test weight and ear length of wheat. Application of panchagavya 5% at 60 and 75 DAS as foliar spray + jeevamrut 500 L ha-1 at sowing and 10% at 30 DAS as foliar spray significantly increase in plant height and dry matter accumulation at 45, 90 DAS and at harvest. Application of different bio-stimulants was recorded significantly higher effective tillers meter–1 row length, spikelets ear-1, grains ear-1, ear length and grain weight ear-1 as compared to control.
