<title>Abstract</title> A two-year field study investigated the effects of varying rates fertilizer NPK 20.10.10 and timing application on vegetative growth biomass yield <italic>T. vogelii</italic> (Fish bean) at area in 2019 2020 cropping seasons. Treatments consisted three N.P.K 20.10.10. (0, 100 200 kg/ha) two periods (pre-anthesis pod commencement), giving a combination 3 x 2 = 18 treatments. Randomized Complete Block Design (RCBD) with replications was used to disperse all treatments...

Food preference of Brachytrupes membranaceus and proximate analysis the nymphal adult stages B. was carried out in Arboretum laboratory University Calabar. The nymphs were sourced from wild. Materials used as feeds included Anarcadium occidentale leaf (AOL), Arachis hypogea leaves nuts (AHL, AHN), Telfairia occidentalis (TOL), Ipomoea batatas tubers (IBL, IBT), also mixtures all vegetables, broiler mash, control. An insectarium made up 20 block compartments covering an area 15×15 m with a...

A two-year field experiment was carried out on the acidic coastal plain sands of South Eastern Nigeria during year 2009 and 2010 planting seasons to study effect lime levels (L = 0, 500 1000 kg ha-1) nitrogen rates (N 40, 80 120 -popcorn varieties (Yellow composite Ashland). Results showed that N application resulted in significantly (p=0.05) higher grain yield at 80kg ha-1 than obtained Nha-1 2009. Yield outstripped by 23.65%. also gave highest popcorn yields 2010, a increase 18.03 % above...

This study analysed the effect of credit on poverty status roasted plantain vendors in Calabar, Nigeria. The described sources credit, comparing recipients versus non-recipients, and relationship between access index alongside socioeconomic factors index. Data was collected from 110 randomly sampled with use structured questionnaire. Poverty measured Foster, Greer Thorbecke (FGT) model class weighted measures. Descriptive statistics were used to examine status, sociodemographic attributes...

Cassava (Manihot esculenta Crantz) is an important staple crop, especially for resource-poor populations. Cassava-based diets are rich in calories but grossly deficient essential mineral elements. A field study southeastern Nigeria aimed at increasing yields and concentrations of bioavailable elements a β-carotene cassava variety, UMUCASS 38 (TMS 01/1371), through agronomic biofortification. randomized complete block design experiment triplicate, with foliar application Zn (3.0 kg ha−1 as...

Confectionary groundnut production is limited by soil acidity in southern Nigeria. This study attempted an improvement of quality limiting pH adjustment to tolerable levels. The influence lime rates and plant spacing on the yield indicators (Arachis hypogaea L.) Calabar, South Eastern Nigeria was evaluated portend best suitable for production. A 4 × 3 factorial randomized complete block design, (0, 0.5, 1.0, 1.5 t/ha), planting distances (30 30, 30 50, 25 50 cm) with three replications were...

Waterleaf apart from being a source of food provides employment and income to mostly female peasant farmers. Field experiments were conducted evaluate effects organic manure types their combinations on the growth yield water leaf in typical tropical humid rainforest 2016 2017 Cropping seasons. The experiment was laid out randomized complete block design (RCBD) with three replications. Treatments included sole poultry (PM) at 10 t ha-1, ha-1 cow dung (CD), 8 oil palm bunch ash (OPBA)...

There is an increasing interest in Sunflower production Nigeria as a substitute oil crop to complement palm and soybean. Two year field experiments were conducted at the Teaching Research Farm of University Calabar evaluate interactive effects intra-row spacing on sunflower varieties, using 3 x 4 factorial experiment consisting four regimes (75 25, 75 30, 35 40 cm) three hybrids (SSL 807, 806 803) randomized complete block design having replications. The cm resulted highest yield seeds (3.95...

Abstract Ripening in plantain results various modifications of its chemical compositions. The objective this project was to determine the effects ripening conditions on functional properties, nutritive and oxalate composition samples. Matured harvested fingers were divided into six portions coded as RP 1 - 5 UPc five each group. left shelf, 2 wrapped foil, 3 immersed water, 4 5% salt solution 6% ripe while analyzed unripe control. samples (RP -RP ) monitored they underwent prepared flour...

Among the greatest challenges of 21st century is maintaining biodiversity and ecosystem services (ESs) to sustainably feed projected 9–10 billion people world by 2050. Presently, incentives preserve ESs in developing economies are limited, implying that there no direct market mechanisms signal scarcity or degradation a service until it fails. public goods with owners. Hence, payment for (PES) voluntary transaction aims at filling this gap creating new services, including carbon...
