EFFECTS OF BLENDED NPSB FERTILIZER RATES ON GROWTH, YIELD COMPONENTS AND YIELD OF BREAD WHEAT (Triticum asetivum.L) VARIETIES AT DEGAM DISTRICT, CENTRAL ETHIOPIA

Abstract: Bread wheat (Triticum aestivum L.) is an important food crop and source of income for farmers at Degam district in central highland of Ethiopia. However, its productivity is mainly constrained by poor soil fertility and lack of site specific fertilizer (NPSB) recommendation in general and in the study area in particular. Thus, field experiment was conducted at Degam district on farmer's field in 2019 main cropping season to investigate the response of bread wheat varieties to blend...

EFFECT OF BLENDED NPSB FERTILIZER RATES ON GROWTH, YIELD COMPONENTS AND YIELD OF COMMON BEAN (Phaseolus vulgaris L.) VARIETIES IN BAKADAWULA ARI DISTRICT, SOUTH OMO ZONE, SOUTHERN ETHIOPIA

Abstract: Common bean is among the most important food and cash legume crops cultivated in southern Ethiopia. But, its productivity in the country remains far below the genetic potential to be attained. This is partly due to low soil fertility management and a lack of improved varieties. Therefore, the study was conducted to evaluate the effect of blended NPSB fertilizer rates on growth, yield components and yield of common bean varieties and to assess economic feasibility of common bean var...

EFFECT OF INTER AND INTRA ROW SPACING ON YIELD COMPONENTS AND YIELD OF CHICKPEA (Cicer arietinum L.) AT HARAMAYA EASTERN, ETHIOPIA

Abstract: One of the basic agronomic practices to improve yield potential of chickpea is identification of optimum plant spacing. Thus, field experiment was conducted to assess the effect of inter-row and intra-row spacing on the growth, yield components and yield of chickpea variety at Haramaya District at main season. The treatment consisted one chickpea variety namely Habru, three inter- row (20, 30 and 40 cm) and four intra- rows spacing (5, 10, 15 and 20 cm). The experiment was laid out...

EFFECT OF BLENDED NPS FERTILIZER RATES ON YIELD COMPONENTS, YIELD, GRAIN QUALITY AND NUTRIENT USE EFFICIENCY OF BREAD WHEAT (Triticum aestivum L.) VARIETIES IN BULE HORA DISTRICT, SOUTHERN OR

Abstract: Bread wheat is one of important food crop in the study area, but its productivity is limited by poor soil fertility. Thus, the study was conducted to investigate the effect of blended NPS fertilizer rates on yield and yield-related traits, nutrient use efficiency and grain quality of bread wheat varieties and assess their economic feasibility. Factorial combination of three bread wheat varieties (Senate, Mandoyu and Local) and six fertilizer rates (0, 50, 100, 150, 200, and 250 kg ...

RESPONSE OF POTATO (Solanum tuberosum L.) TO NPS FERTILIZER AND FARMYARD MANURE UNDER SUPPLEMENTAL IRRIGATION AT DAMOTA, HARAMAYA DISTRICT, EASTERN ETHIOPIA

Abstract: Potato (Solanum tuberosum L.) is one the most important food and cash generating crops in the eastern parts of Ethiopia, particularly East Harerghe zone, where it is grown three times per year. However, the average yield of potato is low, due to low soil fertility and poor ferti lizer management practice. Therefore, a field experiment was conducted in 2021 at Damota, Haramaya district, with the objectives of assessing the influences of integrated use of Farm yard manure and NPS ble...

EFFECTS OF BLENDED NPS FERTILIZER RATES ON YIELD COMPONENTS AND YIELD OF SUGAR CANE VARIETIES (Saccharum officinarum L.) AT FINCHAA SUGAR ESTATE, WESTERN ETHIOPIA

Abstract: Sugarcane (Saccharum officinarum l.) is an important industrial crop that is used for sugar production in Ethiopia.

Landscape ecology and expanding range of biocontrol agent taxa enhance prospects for diamondback moth management: A review.

Abstract: Diamondback moth (Plutella xylostella) is a globally significant pest of Brassicaceae crops that has attracted enormous research investment. It is typical of many agricultural pests, with insecticides remaining the most common method of control, despite frequent cases of resistance in pest populations and the potential for other management options such as natural enemies to provide suppression. Here we review scope to make better use of neglected natural enemy taxa and integrate re...
