SUMMARY
An experiment was conducted to study the “Effect of varieties, FYM and nitrogen levels on yield, content and uptake of nutrients by summer fodder pearl millet under south Gujarat condition” during summer season of 2020 at the college farm, Navsari Agricultural University, Navsari. The soil of the experimental plots was clayey in texture having medium to poor drainage capacity, good water holding capacity, low in available nitrogen and organic carbon, medium in available phosphorus and available potassium. The soil was neutral in reaction with normal electric conductivity. Total twelve treatment combinations comprising of two varieties (V1: GAFB-4 and V2 GFB-1), two levels of FYM (F1: control and F2: 5.0 t FYM/ ha) and three levels of nitrogen treatment (N1:75% RDN/ha, N2: 100% RDN/ha and N3:125% RDN/ha) were evaluated in factorial randomized block design with three replications. Fodder pearl millet variety GAFB-4 recorded significantly higher plant height at harvest (142.16 cm), green fodder yield (272.69 q/ha), dry matter yield (74.70 q/ha) as well as uptake of nitrogen (74.09 kg/ha), and phosphorus (15.16 kg/ha) over variety GFB-1. Net returns (Rs 60601/ha) and B: C ratio (3.86) was also found maximum under the same variety. Incorporation of 5.0 t FYM/ha significantly increased plant height (142.11 cm) at harvest, green fodder yield (280.38 q/ha), dry matter yield (76.34 q/ha), nitrogen content (1.21 %), phosphorus content (0.238 %) as well as uptake of nitrogen (80.10 kg/ha), phosphorus (15.76 kg/ha) and potash (89.71 kg/ha) over control. The higher net returns (Rs. 62906/ha) and B: C ratio (4.76) was incurred under the application of 5.0 t FYM/ha and control, respectively. An application of 125 % RDN/ha significantly increased plant height at harvest (144.82 cm), green fodder yield (279.32 q/ha), dry matter yield (75.58 q/ha), nitrogen content (1.29 %), phosphorus content (0.245 %), potash content (1.38 %) and uptake of nitrogen (85.02 kg/ha), phosphorus (16.01 kg/ha) and potash (90.33 kg/ha) over 75 % RDN. The maximum net returns (Rs. 62246/ha) and B: C ratios (3.89) were also found under the same treatment.
