Performance of tomato to combined application of foliar Algifol and granular NPK fertilizers on a typic haplustalf of Nigerian savanna.

摘要

The effects of Algifol (50, 100, 150 or 200% of the recommended 10 ml/100 ml of water) and NPK (25, 50, 75 or 1005 of the recommended 125:50:50 kg N, P2O5 and K2O/ha, respectively), singly or in combination (50% Algifol + 100% NPK, 50% Algifol + 25% NPK, 100% Algifol + 50% NPK, 100% Algifol + 75% NPK, 100% Algifol + 100% NPK, 150% Algifol + 50% NPK, and 200% Algifol + 25% NPK), on the performance of tomato (cv. ROMA-VF) grown on a typic haplustalf collected from Zaria, Nigeria, were studied under greenhouse conditions. The treatments did not significantly vary with regard to their effects on plant height at 6 and 10 weeks after transplanting (WAT) in 1999, plant height at 6 WAT in 2000, and number of leaves per plant at 6 WAT in both years. The highest number of leaves at 10 WAT in 1999 was obtained with 150% Algifol + 50% NPK (270.50 cm) and 150% Algifol + 50% NPK (235.0 cm). Plant height at 10 WAT in 2000 was greatest (59.25 cm) with 100% Algifol + 25% NPK. The highest fresh fruit yields per plant were obtained with 50% Algifol in 1999 (501.0 g) and 2000 (525.0 g), 50% NPK in 1999 (574.0 g) and 2000 (677.5 g), 50% Algifol + 100% NPK and 100% Algifol + 25% NPK in 1999 (484.5 and 482.5 g), and 50% Algifol + 100% NPK, 100% Algifol + 50% NPK, and 100% Algifol + 75% NPK in 2000 (665.0, 702.5 and 757.5 g, respectively)..
