SUMMARY
A field experiment was conducted during summer season of 2020 at the college farm, Navsari Agricultural University, Navsari, to study the “Effect of varieties, FYM and nitrogen levels on summer fodder pearl millet under south Gujarat condition.” The soil of the experimental field 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 receded significantly higher plant height at 30 DAS (42.65 cm), at harvest (142.16 cm), leaf : stem ratio (0.41), number of leaves per plant (11.61), green fodder yield (272.69 q/ha), dry matter yield (74.70 q/ha), and crude protein yield (536.0 kg/ha) over variety GFB-1. Net
returns (Rs 60601/ha and B: C ratio (3.86) was also found maximum under the same treatments.
Incorporation of 5.0 t FYM/ha significantly increase plant height harvest (142.11 cm), leaf: stem ratio (0.41), green fodder yield (280.38 q/ha), dry matter yield (76.34 q/ha), crude protein content (7.54 %) and crude protein yield (579.48 kg/ha) over control. The higher net returns (Rs 84115/ha) and B: C ratio (4.76) was incurred under the application of 5 t FYM/ha and control, respectively. An application of 125 % RDN/ha significantly increase plant height at 30 DAS (44.13 cm) and at harvest (144.82 cm), leaf: stem ratio (0.43), number of leaves per plant (12), green fodder yield (279.32 q/ha), dry matter yield (75.58 q/ha), crude protein content (8.06%), crude protein yield (615.18 kg/ha) and higher net returns (Rs. 62246/ha) and B: C ratio (3.89) over 75 % RDN. over.
