SUMMARY

The field experiment was conducted to study the effect of different levels of phosphorus and sulphur on number and dry weight of nodules per plant in chickpea at the Instructional Farm, Department of Agricultural Chemistry & Soil Science, Junagadh Agricultural University, Junagadh during rabi season of 2015-16. The results revealed that the number and dry weight of nodules were increased significantly with the progressive increase in phosphorus levels up to 60 kg/ha at 45 DAS. Likewise, the number and dry weight of nodules were also increased significantly with the progressive increase in sulphur levels up to 40 kg/ha at 45 DAS. However, the interaction between phosphorus and sulphur was found to be non-significant on number of root nodules per plant and dry weight of nodules per plant at 45 DAS.

Key words: Dry weight, nodules/plant, nutrient uptake, chickpea

SUMMARY

A field experiment was conducted during kharif season of 2016 at Udaipur, Rajasthan on clay loam soil to assess the effect of fertility levels (60 N+30 P₂O₅+30 K₂O kg/ha, 80 N+40 P₂O₅+40 K₂O kg/ ha and 100 N+50 P₂O₅+50 K₂O kg/ha) on single cut genotypes (SPH 1725, SPH 1794, SPH 1797, SPV 2317, CSH 13 and CSV 21F) of fodder sorghum. Amongst genotypes, SPH 1752 proved most efficient as it gave significantly higher green (47.73 t/ha) and dry (14.24 t/ha) fodder yields, net returns (Rs. 41150/ha) and B : C ratio 1.60. The crop fertilized with 100 N+50 P₂O₅+50 K₂O kg/ha recorded significantly higher green (41.08 t/ha) and dry (12.26 t/ha) fodder yield as well as net returns (Rs. 30803/ ha) over application of 60 N+30 P₂O₅+30 K₂O kg/ha and 80 N+40 P₂O₅+40 K₂O kg/ha.
