Upland rice response to nutrient application in Uganda

Upland rice (Oryza spp.) yields are low in Uganda, partly because of little fertilizer use. Three on-station trials and two clusters of on-farm trials were conducted in Uganda at approximately 1000 m elevation to determine: yield response to N, P and K application; economically optimal nutrient rates (EOR); and N use efficiency components. Mean grain yield, with hulls, was 1.3 and 3.7 Mg ha-1 with 0 and 100 kg ha-1 N...

The use of ecological methods in vegetative studies of plant species and abundance in south-eastern Nigeria

The study on ecological survey of plant species biodiversities and abundance in Southeastern Nigeria was conducted between January 2012 and 2013 at Anambra State, Nigeria to determine the plant species biodiversities and abundance in three forest fringes viz: community, shrine and reserves using measures based on floristic, stratified random sampling, plotless measure and point centre quarter methods, respectively....

Influence of medium type and growth regulators on in vitro micropropagation of pineapple (Ananas comosus (L.), var. Smooth cayenne)

Aseptic cultures of pineapple ‘smooth cayenne’ were established from shoot tip explants. They were initiated on Murashige and Skoog (MS) basal medium with vitamins supplemented with various combinations of 6-benzylaminopurine (BAP) (0, 0.1, 0.2, 0.3 and 0.4 mg L-1) and Gelrite [1.0 g L-1 (semi-liquid), 1.5 g L-1 (semi-solid) and 2.0 g L-1 (solid)]. Explants were transferred five weeks...
