Abstract

The study was conducted to evaluate intercropping forage production between inoculated arbila (Phaseolus lunatus) and sorghum (Sorghum bicolor) at different planting space of arbila and different row number of sorgum. The experiment was arranged factorially according to completely randomised design. The first factor was two planting space of arbila i.e. J1 (120 cm) and J2 (180 cm). The second factor was three different row number of sorghum i.e. P1 (1 row), P2 (2 rows), P3 (3 rows). The replication for each treatment combination was three giving total number of experimental units of 18. Variables abserved were organic matter (OM), crude protein (CP), crude fiber (CF), nitrogen free ekstract (NFE), ether extract (EE), and ash contents of intercropped forage. Results showed that nutritional value of intercropping forage between  arbila and sorgum was better compared with monoculture crop of either arbila or sorghum. At intercropping, OM content of all treatments were high, except for treatment  J1P1. The lowest CF was noticed for treatment J1P2 (30.64%). The highest CP content was for J1P1 (16.16%) but  the CP content of J1P2 was still quiet good (13.36%). EE values were relatively similar for all treatments. The highest value for NFE was for J1P3 (48.35%) and J2P1 (48.45%) but the value for J1P2 was still reasonably good (48.35%). The ash content for treatment J1P1, J1P2, and J1P3 was 8.62%, 7.51%, and 7.15% respectively, and it was considered good enough for forage. In conclusion, intercropping between arbila at 120 cm planting space and 2 or 3 rows of sorghums produces the best nutritive content of forage for ruminant feed.

Abstract

[PHYSIOLGICAL PERFORMANCES AND YIELD OF GUINEA GRASS (Panicum maximum Jacq.) AS AFFECTED BY APPLICATIONS OF GYPSUM, MANURE, AND NITROGEN]. Agricultural production on saline soil is often hampered by the inherent soil properties that limit the plant to gain optimal growth and development. Objective of this study was to determine the effects of gypsum, manure, and nitrogen applications? on the physiological characteristics and yield of guinea grass. A factorial experiment was set up in a greenhouse, involving two levels of manure (0 and 20 ton ha-1), four levels of gypsum (0, 0.75, 1.5, and 3 ton ha-1), and three levels of nitrogen (0, 50 kg N ha-1 in form of nitrate, and 50 kg N ha-1 in form of ammonium). Application of manure at 20 ton ha-1 produced higher leaf area per plant (LAPP), photosynthetic rate, nitrogen uptake, relative growth rate (RGR), plant height, and forage and dry matter productions as compared to no manure. Similarly, LAPP, photosynthetic rate, and net assimilation rate (NAR) had increased linearly as the gypsum applications were increased from 0.75 to 3 ton ha-1. ANR were increased in quadratic fashion on both manure treatments in accordance with the increment of gypsum applications. LAPP, NAR, ANR, N uptake, plant height, RGR, and dry matter production were increased by application of either nitrate or ammonium application, whereas the highest forage production was found on combination of manure at 20 ton ha-1 and N at 50 kg ha-1 in form of ammonium.
