Response of fenugreek (Trigonella foenum-graecum) genotypes to planting geometry, agro-chemicals and sulphur levels

A field experiment was conducted at Udaipur during winter seasons of 2005–07 to evaluate the effect of two genotypes of fenugreek (Trigonella foenumgraecum L.) (indeterminate type ‘Rmt 1’ and determinate type ‘Rmt 305’), two crop geometry (30 cm × 10 cm and 20 cm × 15 cm), three agro-chemicals levels [Control, thiourea 1,000 ppm and thioglycolic acid (TGA) 100 ppm] and two levels of sulphur (0 and 40 kg S/ha) on the productivity and nutrient uptake. Results indicated that the determinate type ‘Rmt 305’ recorded higher seed yield and N, P and S uptake, while the indeterminate type ‘Rmt 1’ was found superior in respect to haulms and biological yields. The crop geometry of 20 cm × 15 cm exhibited higher seed yield (1.32 t/ha) and haulms yield (5.29 t/ha), which were 7.20 and 4.75% higher, over the crop geometry 30 cm × 10 cm respectively. Crop geometry of 20 cm x 15 cm also enhanced uptake of N, P and S. Foliar application of thiourea 1,000 ppm and TGA 100 ppm at flower initiation and 15 days thereafter and application of sulphur at the recommended dose resulted significant improvement in yield and N, P and S uptake of seed, haulms and total uptake over control.
