The field experiment was conducted at Students’ Research Farm, Khalsa College, Amritsar during kharif2019-20. There were total of 10 treatments comprising two cultivars i.e. C1 – CIM-Jagriti and C2 – Subodhakand five growing media i.e. G1 – Cocopeat; G2 – Sawdust; G3 – Vermiculite; G4 – Mixture (cocopeat + sawdust+ vermiculite in 1:1:1) and G5 – Soil (control). The results revealed that higher growth and yield attributeswere found in cv. Subodhak than cv. CIM-Jagriti but they had non-significant difference whereas bacoside-A content was found to be higher in CIM-Jagriti than Subodhak. Growing media had influence on theperformance of brahmi plants. Brahmi grown in G1 responded better than other media. It was observedthat the growth and yield parameters of brahmi were significantly higher in G1 than G2, G3, G-4 and G5, butwas statistically at par with G-4. Plants grown in G5 showed significantly lower results than other media.

A field experiment was conducted during kharif season of 2019-20 at Department of Agriculture, Khalsa College, Amritsar. It consisted of 10 treatment combinations which included two cultivars (CIM-Jagriti and Subodhak) and five nutrient management, viz. Vermicompost 10 t ha-1, FYM 20 t ha-1, Vermicompost 5 t ha-1+ FYM 10 t ha-1, Recommended dose of NPK fertilizers 100: 60: 50 kg ha-1 and Hydroponics (half-strength Hoagland solution). The results revealed that cv. Subodhak had produced more yield than cv. CIM-Jagriti but bacoside-A content was higher in the latter (16 percent higher). Among nutrient management, Brahmi grown in hydroponics (half-strength Hoagland solution) had significantly higher growth and yield attributes (viz. main shoot length, number of shoots, number of leaves, leaf area, fresh and dry weight) while FYM 20 t ha-1 recorded lowest growth and yield. Additionally, hydroponically grown brahmi had 7.5 percent more bacoside-A content than soil grown brahmi.

The present investigation entitled “Weed control efficiency and grain yield of wheat (Triticum aestivum L.)” under Pre-and Post-Emergence Herbicides”was carried out at student research farm, Department of Agriculture, Khalsa College Amritsar. The soil of the experimental field was sandy loam texture with normal pH and electrical conductivity, low in organic carbon and available nitrogen, medium in available phosphorus and high in available potassium. The experiment was laid out in randomized block design with 12 treatments comprising T1 (Control), T2 (Pinoxaden 50 ml at 28 days after sowing (DAS), T3 (Pinoxaden 50 ml at 42 days after sowing (DAS), T4 (Pinoxaden 50 ml at 56 days after sowing (DAS), T5 (Pendimethalin 750 ml), T6 (Pendimethalin 750 ml + T2 ), T7 (Pendimethalin750 ml + T3 ), T8 (Pendimethalin 750 ml + T4 ), T9 (Pendimethalin 1000 ml), T10 (Pendimethalin 1000 ml + T2 ), T11 (Pendimethalin 1000 ml + T3 ), T12 (Pendimethalin 1000 ml + T4 ) replicated thrice. From the experiment it was observed that T10 (Pendimethalin 1000 ml + T2 ) was found most effective in controlling weed population, dry matter accumulation of weeds and produced higher grain yield, straw yield and weed control efficiency than T7 , T8 , T5 , T3 , T4 and least were in T1. Treatment T10 remained at par in terms of growth and yield attributes to T11, T12, T9 , T6 , T2 and was significantly better than T3 , T4 , T5 , T7 and T8 . All the weed control treatments produced significantly higher returns than the control.
