Ten crop species were evaluated for their relative drought tolerance at the seedling stage. Healthy seeds of each crop were planted in wooden boxes of 130 cm length, 65 cm width and 15 cm depth, filled with 3 soil types (river sand, loamy sand and sandy loam) and watered daily. A week after germi...

A simple screening method was developed that accurately discriminates between drought and susceptible cowpea(Vigna unguiculata(L) walp). Wooden boxes (130 cm length. 65cm width. 15cm depth) made of 2.5cm thick planks were lined with polythene sheets, filled with a 12cm layer of soil and sand mixt...

Twelve cowpea (Vigna unguiculata) varieties were planted in wooden boxes of 130 cm length, 65 cm width, and 15 cm depth filled with sand and soil mixture (1:1) at 10 cm row to row and 5 cm plant-to-plant distances. The boxes were watered daily until the unifoliate leaves had fully expanded and th...

Maize (Zea mays L.) hybrids resistant to Striga hermonthica (Del) Benth and tolerant to drought are vital to the sustainability of productivity of the maize-based farming systems of West and Central Africa (WCA). Thirty-six diallel crosses derived from nine early maturing white maize inbreds were...

Cassava (Manihot esculenta Crantz) is a staple food for over 600 million people in the tropics and sub-tropics and is increasingly used as an industrial crop for starch production. Cassava has a high growth rate under optimal conditions but also performs well in drought-prone areas and on margina...

An attempt was made to introduce potato (Solanum tuberosum L.) in hot arid water scarce zone of Western Rajasthan, India. Eight CIP-bred potato clones were evaluated along with two controls, viz. Kufri Pukhraj and Kufri Surya on farmer’s field at Jodhpur, Rajasthan under normal and moderate water...

Cowpea (Vigna unguiculata [L.| Wulp.) is primarily grown in dry regions in the tropics, particularly in sub-Saharan Africa. Drought is important among several yield-reducing factors. Nine hundred cowpea accessions from the Genetic Resources Unit of IITA were evaluated for drought tolerance in a f...

Vitamin A deficiency, drought, low soil nitrogen (low N) and Striga hermonthica parasitism of maize (Zea mays L.) cause malnutrition and food insecurity in sub-Saharan Africa. The objectives of this study were to determine combining abilities of extra-early provitamin A (PVA) lines, classify them...

Abstract A field experiment was conducted during 2014 and 2016 rainy season at Tudun Wada, Kano and Shika, Zaria in the Northern Guinea Savanna of Nigeria in order to study the physiological responses of maize hybrids under low nitrogen. The experiment consisted of two nitrogen levels 0 and 120 N...
