Abstract:
A field experiment was conducted on clayey soil having low status of organic carbon and available phosphorus, high of available potassium and medium of available sulphur at Targhadia (Dist. Rajkot) during kharif season of 2011-12 to 2016-17 to study the effect of phosphorus management on yield, nutrient uptake by sesame and post-harvest soil fertility under rain fed condition. The experiment comprising of different twelve treatments laid out in Randomized Block Design with three replications. The effect of phosphorus management treatments on plant height as well as on number of branches per plant were remained non-significant, whereas, number of capsules per plant were found significant in pooled results. The effect of phosphorus management on seed yield of sesame was found significant during three successive year and in pooled results, maximum seed yield (1035 kg/ha) were recorded under application of 50 kg P2O5/ha through SSP and which were statistically at par with application of 25 kg P2O5/ha through SSP. Whereas, the lowest seed yield (765 kg/ha) was recorded under control treatment i.e. RDN-50 kg N/ha.The effect of phosphorus management on stalk yield of sesame crop was found non-significant in all three successive years. However, it was found significant in pooled result. The uptake of N, P, K and S by sesame significantly influenced due to different P-fertilization treatments. The highest uptake of N (21.7 kg/ha), P (5.05 kg/ha), K (21.29 kg/ha) and S (5.28 kg/ha) by sesame was recorded when it was fertilized with 50 kg P2O5 through SSP. The available phosphorus, potash and sulphur status in the soil after harvest were significantly influenced due to different treatments. However, effect of different treatments on organic carbon status, pH and EC of the soil was found non-significant.
