A field experiment was conducted during the rabi season of 2024-25 at the College of Agriculture, Agriculture University, Jodhpur (Rajasthan), to evaluate the effect of water stress and foliar application of agrochemicals on productivity and profitability of chia (Salvia hispanica L.). The experiment was carried out in a split plot design with three irrigation levels, recommended irrigation (I0), one irrigation skip (I1) and two irrigation skips (I2), as main-plot treatments and four foliar-applied agrochemicals, control (C0), thiourea @ 2% (C1), potassium nitrate @ 100 ppm (C2) and salicylic acid @ 100 ppm (C3), as sub-plot treatments, replicated thrice. Results revealed that deficit irrigation significantly reduced growth and yield of chia. Recommended irrigation recorded the highest plant height, dry matter accumulation, yield attributes and seed yield (540.02 kg ha–1). Among agrochemicals, foliar application of potassium nitrate proved most effective, producing maximum spikes per plant (13.28), spike length (11.28 cm), spike weight (12.28 g) and seed yield (507.25 kg ha–1). Economic analysis showed the highest gross return (₹81,575 ha–1), net return (₹48,302 ha–1) and B:C ratio (2.45) under recommended irrigation, while potassium nitrate recorded maximum profitability among agrochemicals (B:C ratio 2.45). The study concludes that integration of adequate irrigation with foliar application of potassium nitrate is an effective strategy for enhancing productivity and profitability of chia under arid conditions.

A field experiment entitled Effect of Organic Manures, Rhizobium and Bijamrit on Growth and Yield of Mungbean [Vigna radiata (L.) R. Wilczek]” was conducted at the Dr. B.R.C. Agricultural Research Station, Mandor, during Kharif 2024 on a loamy sand soil. The experiment was laid out in a Factorial Randomized Block Design (FRBD) with twelve treatment combinations replicated three times. The treatments comprised four organic manures, viz., FYM @ 6 t ha⁻¹, vermicompost @ 2 t ha⁻¹, poultry manure @ 0.75 t ha⁻¹, and Jivamrit @ 500 L ha⁻¹ (soil application) + 10% foliar spray at 30 DAS, along with three seed treatments, viz., Bijamrit @ 200 ml kg⁻¹ seed, Rhizobium @ 25 ml kg⁻¹ seed, and Bijamrit + Rhizobium. The results revealed that nutrient management through organic sources significantly influenced the growth and yield attributes of mungbean. Application of poultry manure @ 0.75 t ha⁻¹ significantly increased plant height, dry matter accumulation, branches per plant, pods per plant, grains per pod, grain yield, stover yield, and biological yield over the other organic manures; however, it remained statistically at par with vermicompost @ 2 t ha⁻¹. Similar trends were observed for seed protein content, available soil N, P, and K at harvest, and microbial population at harvest. The highest benefit-cost ratio (4.1) was recorded with poultry manure. Among the seed treatments, the combined application of Bijamrit @ 200 ml kg⁻¹ seed and Rhizobium @ 25 ml kg⁻¹ seed recorded the highest growth and yield attributes and was found statistically at par with Rhizobium @ 25 ml kg⁻¹ seed alone. The highest benefit-cost ratio (3.4) was also recorded under the combined application of Bijamrit and Rhizobium. The study concluded that the application of poultry manure @ 0.75 t ha⁻¹ along with seed treatment of Bijamrit @ 200 ml kg⁻¹ seed + Rhizobium @ 25 ml kg⁻¹ seed significantly enhanced mungbean yield and economic returns.
