A field experiment was conducted during Rabi, 2022-23 at Research Farm, School of Agriculture, Suresh Gyan Vihar University, Jaipur (Rajasthan) to study the “Effect of Agro- Chemicals on Growth, Yield and Economics of Indian Mustard (Brassica juncea L.) under Limited Irrigation”. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36 %) and available N (171.48 kg ha-1) and medium available P (15.2 kg ha-1) and available K (232.5 kg ha-1). The experiment was laid out in Randomized Block Design with nine treatments (T1: Control, T2: Cycocel @ 250 ppm, T3: Cycocel @ 500 ppm, T4: Hydrogel @ 2.5 kg ha-1, T5: Hydrogel @ 5 kg ha-1, T6: Cycocel @ 250 ppm + hydrogel @ 2.5 kg ha-1, T7: Cycocel @ 250 ppm + hydrogel @ 5 kg ha-1, T8: 4 Cycocel @ 500 ppm + hydrogel @ 2.5 kg ha-1, T9: Cycocel @ 500 ppm + hydrogel @ 5 kg ha-1) each replicated thrice. The results showed that application of Cycocel @ 500 ppm + hydrogel @ 5 kg ha-1 recorded significantly higher plant height, dry matter accumulation, No. of siliquae/plant, No. of seeds/siliqua and test weight. The above treatment proved superior to the remaining treatments with respect to seed yield, biological yield (5017.96 kg ha-1) and nutrient uptake. Maximum net returns and benefit cost ratio (2.16) were also obtained with application of Cycocel @ 500 ppm + hydrogel @ 5 kg ha-1 (T9).

Mustard, Hydrogel, Cycocel, Growth, Yield, Economics

It is concluded that treatment T9 (Cycocel @ 500 ppm + hydrogel @ 5 kg ha-1) was found to be best for obtaining maximum grain yield. It also fetched the maximum gross return, net returns and B:C ratio.
