Effect of Thiourea and Salicylic Acid on Growth and Productivity of Indian Mustard (Brassica juncea L.) nder Moisture Stress Condition

Abstract

A field experiment was conducted at Experimental area, School of Agriculture, Lovely Professional University during the rabi season of 2021-22 to determine the effect of thiourea and salicylic acid on growth and yield of Indian mustard (Brassica juncea L.) under moisture stress condition. This experiment consists of 12 treatments were replicated thrice and was laid down Randomized block design. The application of thiourea and salicylic acid had significant effect on growth and yield of Indian mustard (Brassica juncea L.) under moisture stress condition. The maximum plant height (133.33 cm), number of branches (6.70), leaf area index (5.64), dry matter accumulation (17.32 g) at harvest, seed yield (2213.33 kg ha-1), stover yield (5980.00 kg ha-1) and harvest index (27.01%) were recorded under T12 treatment (thiourea spray @500 ppm at flowering + thiourea spray 500 ppm at siliqua initiation + 200 ppm salicylic acid at flowering) than rest of treatments. Application of thiourea spray @ 500 ppm at flowering + thiourea spray 500 ppm at siliqua initiation + 200 ppm salicylic acid at flowering indicated maximum plant height (cm), number of branches, leaf area index, dry matter accumulation (g) and productivity of Indian mustard with two irrigations. Thus, it can be potential alternative to increase Indian mustard production.
