Abstract
The existing experiment was conducted at MJRPU, Jaipur during 2021-22 season. Nowadays fertility of soil was decreasing day by day so the present investigation was conducted to assess the fertility as well as other effects on growth and yield of both the crops. The experiment was conducted using randomized block design with 10 treatment combination replicated thrice. The treatments were as T1-Pearl millet (drilled) + Green gram (1:1) 45 cm, T2-Pearl millet (drilled) + Green gram (2:1) 45 cm, T3-Pearl millet (drilled) + Green gram (1:2) 30 cm, T4-Pearl millet (drilled) + Green gram (2:2) 30 cm, T5-Pearl millet (T. P.) + Green gram (1:1) 45 cm, T6-Pearl millet (T. P.) + Green gram (2:1) 45 cm, T7-Pearl millet (T. P.) + Green gram (1:2) 30 cm, T8-Pearl millet (T. P.) + Green gram (2:2) 30 cm, T9-Pearl millet sole (drilled) 45 cm and T10-Pearl millet sole (T. P.) 45 cm. From the current examination it can be concluded that higher growth parameters, growth, grain yield, straw yield, and net realization of summer pearl millet could be achieved either sole pearl millet crop when transplanted at 45 cm or 30 cm, or when it is transplanted as an intercrop with green gram at a row ratio of 2:1 of 45 cm or sole pearl millet crop when sown by drill method at 45 cm row spacing. The soil available nitrogen also found non-significant at harvest.
