Response of fertilizer levels and genotypes on productivity of fenugreek (Trigonella foenum-graecum L.)

Abstract

An experiment was conducted during Rabi season of 2012-13 to study the e crop geometry, Key words: Crop geometry, fertility . ffect of fertilizer levels and genotypes on growth and yield of fenugreek (Trigonella foenum-graecum L.). The field experiment consisted of two spacing viz., 30 cm x10 cm (S ), 22 cm x 10 cm (S ) and two fertilizer levels viz., F - 40:40:20 kg NPK per ha, F - 1 2 1 2 50:50:25 kg NPK per ha and three genotypes viz., Ajmer Fenugreek-1 (V ), Ajmer Fenugreek-3 (V ) and Ajmer 1 2 Fenugreek-4 (V ). The experiment was laid out in factorial randomized block design with three replications. Result 3 -1 -1 -1 revealed that significantly higher seed yield (2437.4 kg ha ), straw yield (3356.8 kg ha ), biological yield (5794.2 ha ), -1 net return (Rs.57358 ha ) and BCR (2.5) were recorded with sowing at a spacing of 22 cm x 10 cm as compared to 30 cm x 10 cm spacing but numbers of pods per plant (37.0), seed yield per plant (43.5 g), test weight (16.6 g) and harvest index (41.80) were higher in 30 cm x 10 cm spacing. Irrespective of spacing and genotypes, the application of 125 percent RDF ( NPK 50:50:25) recorded significantly more pods (40.7) per plant, seed yield (41.9 g) per plant, seed -1 -1 -1 yield (2249.1 kgha ), straw yield (3094.2 kgha ), biological yield (5343.2 kgha ), 1000 seed weight (16.4 g), harvest -1 index (42.07), net return (Rs.51091.0 ha ) and BCR (2.3) as compared to 100 percent RDF(NPK 40:20:20). -1 Significantly higher number of pods (42.9/pod), seed yield (45.9 g/plant), seed yield (2270.7 kgha ), straw yield -1 -1 -1 (3066.8 kgha ), biological yield (5337.4 kgha ), net return (Rs.51927.0 ha ) and BCR (2.3) were recorded with AFg-4. Thus, it is inferred that sowing at 22 cm x 10 cm spacing with application of 125 percent of recommended dose of fertilizer is better for realizing higher yield, net return and BCR.
