On-farm assessment of cassava root yield response to tillage, plant density, weed control and fertilizer application in southwestern Nigeria

چکیده
Abstract Cassava is growing in importance Nigeria as a food and industrial crop. Current yields are low due to poor soil fertility because farmers do not use improved germplasm, clean planting material, or crop management Nigeria. To provide feasible agronomic recommendations targeting increased root yield, the effects of tillage intensity, fertilizer application, plant density weed control were tested 230 farmers’ fields southwestern over two years. In 2016, treatments zero, single double passage with disc plough, followed by ridging (soil shaping) versus leaving flat. Fertilizer application at 75:20:90 kg ha−1 NPK was against densities (10,000 12,500 ha−1) compared. 2017, 10,000 plough excluded, while pre- post-emergence herbicide farmer’s choice (i.e. manual weeding using hand hoe) introduced. harvested 12 months after planting, recorded fresh mass. (15.9 Mg had minor advantage (14.3 ha−1), zero produced 12.9 (P

The Effect of N Fertilizer and Plant Density on Green Peppers Yield and Its Components
Pepper is one of the nutrition demanding vegetable. In order to compare N fertilizer uptake and plant numbers per area unit, an experiment was conducted with replications. In which fertilizer was the main factor and included Ammonium nitrate in 7 levels (0, 80, 160, 240 kg /ha-1) and 40+40, 80+80, 120+120 kg/ha-1 (in 2 stages i.e. Half of these amounts appliedpre planting ...
