Abstract

This experiment was canied out to study -the effects of different seeding date on the yields and nutritional value of Pearl millet. Seeding dates were $S_1$,$S_2$,$S_3$,$S_4$, and $S_5$, and harvest dates were $S_1$, (7 July) and $S_2$, (18Augst), respectively. The results were summarized as follows: 1. Plant length was not influenced by seeding date at each harvest. The seeding date at $S_4$,showed the longest plant length of 90.4 an on average per year, which was longer by 17 cm compared to 73.3 cm harvested at $S_5$. 2. Total dry matter yield was not significantly different among seeding dates. Total dry matter yield in 1993 increased according to delayed seeding date from $S_1$ to $S_4$. Dry matter yield of 17.3 tonha was obtained in $S_4$. 3. The relative yield of leaf tended to increase with delayed seeding date, and varied from 60% to 69%. 4. Dry matter ratio decreased with delayed seeding date from $S_1$,(20 April) to $S_5$ (30 May), and varied from 15.6% to 12.3%. 5. Crude protein content of leaf at 1st and 2nd harvest and stem at 1st harvest were significantly different among various seeding dates. Avenge crude protein content increased with delayed seeding date from 9.0% at $S_1$ (20April) to 12.8% at (30 May) $S_5$ (30 May). 6. NDF and ADF of leaf at the 1st harvested were significantly different among seeding dates. NDF content decreased with delayed seeding date from 61.9% to 57.8%, and ADF content decreased with delayed seeding date from 34.8% to 32.2%.
