Yield Economics and Energy Use Efficiency in Organic Wheat Triticum aestivum L as Influenced by Sowing Methods and Nutrient Management Practices

Abstract

newline A field experiment entitled Yield, Economics and Energy Use Efficiency in Organic Wheat (Triticum aestivum L.) as Influenced by Sowing Methods and Nutrient Management Practices was conducted at Organic Farming Unit (Agronomy), Rajasthan College of Agriculture, MPUAT, Udaipur during Rabi 2021- 22 and 2022-23. The soil of the experimental site was clay loam in texture with 252.15, 25.61 and 305.30 kg ha -1 available nitrogen, phosphorus and potassium, respectively. The experiment was laid out in split plot design with four replications, assigning 96 treatment combinations comprising with three sowing methods in main plots viz., S1- (Flat row sowing), S2- (FIRB) and S3- (Zero tillage) and eight nutrient management practices in sub plots viz., M1-(100 % RDN through FYM as basal), M2- (50 % RDN through FYM as basal + 50 % RDN with 1st irrigation), M3-(75 % RDN through FYM as basal + 25 % RDN with 1st irrigation), M4-(50 % RDN through FYM as basal + 25 % RDN with 1st irrigation + 25 % RDN with 2nd irrigation), M5-(M1 + jeevamrit at 500 L ha-1 at sowing and 1st irrigation + panchagavya at 5 % at booting stage), M6-(M2 + jeevamrit at 500 L ha-1 at sowing and 1st irrigation + panchagavya at 5 % at booting stage), M7-(M3 + jeevamrit at 500 L ha-1 at sowing and 1st irrigation newline+ panchagavya at 5 % at booting stage) and M8-(M4 + jeevamrit at 500 L ha-1 at newlinesowing and 1st irrigation + panchagavya at 5 % at booting stage). newlineResults of two year experimentation revealed that growth attributes such as plant height, plant dry matter accumulation, CGR, RGR and yield attributes viz., number of effective tillers, number of grains per ear, ear length, 1000- grain weight, grain weight per ear, and grain yield and straw yield were found significantly higher at FIRB sowing method over flat row and zero tillage sowing method. The protein content, total chlorophyll content, nutrient content (grain and straw), nutrient uptake (grain, straw and total) of wheat were found significantly higher at FIRB sowing method over rest of the treatm
