چکیده
Cassava is a perennial crop that can adapt to periods of drought at different times in growing season, which permits scheduling planting and harvest develop production systems supplying roots continuously. However, farmers plant cassava the onset rains creates glut results unattractive root prices. Thus, need understand how varieties respond dates ages be able use opportunities income generation may arise from flexible resulting price dry matter (DM) variabilities. this study was conducted identify best time for (TME419 TMS581) determine effect fertilizer on DM yields three locations (Idi-Ose, Moniya Ido) Nigeria, over two years. The overall objective provide information guide schedule harvesting Nigeria. trials were using factorial split-split plot design. Effects early, mid late combined with 9, 11 13 months after (MAP) tested. Fertilizer treatments included control (F0) applications 75 kg N ha?1, 20 P ha?1 90 (F1), 135 (F2) 180 (F3) K ha?1. A yield increase 44.8% observed when age increased 9 MAP, an 13.1% indicating delaying harvests does across all dates. In contrast, differences between marginal, 8.1% early mid-planting date 9.5% significantly interacted location largest responses Ido. compared Ido by 15.38%, 23.1% 16.7% F1, F2 F3, respectively. Responses inconsistent Idi-Ose. With fertilizer, could benefit targeting seasons shortage high prices, would processing industries securing year-round supply.

In order to study the effect of organic fertilizer on shoot yield and essential oil content of lavender, this experiment was conducted in the Research Institute of Forest and Rangelands, Karaj, Iran, in 2013-14. The treatment groups consisted of vermicompost (0, 5, 10 and 15 ton/ha) and cow manure (0, 10, 20 and 30 ton/ha). The experimental design was a factorial experiment based on randomized ...
متن کاملPhysiological Behaviour and Yield Performances of Hybrid Rice at Different Planting Dates in Aus Season
Two field experiments were conducted in 2009 and 2010 to evaluate some physiological traits and yield of three hybrid rice varieties (BRRI hybrid dhan2, Heera2, and Tia) in comparison to BRRI dhan48 in Aus season. The experiments involved four planting dates (1 April, 16 April, 1 May and 16 May). Compared to BRRI dhan48, hybrid varieties accumulated greater shoot dry matter at anthesis, higher ...
