Ho wever, the production requirements of this crop are seldo m known. The study was conducted to investigate the effects of soil type and cattle manure on init ial establishment and growth of M. oleifera. Greenhouse experiments were conducted at Africa University, Zimbabwe in a 4×4 factorial treat ment structure laid in a randomized co mplete block design replicated 3 times. Sandy, sandy loam, clay loam and clay soils were used while cattle manure was applied to all the soils at levels of 0, 10, 20 and 40% on mass to mass basis. Results showed that, plant height, nu mber of branches, basal stem d iameter, root, shoot and total dry biomass significantly increased (p<0.05) with an increase in the amount of cattle manure applied. An increase of 173% in M. oleifera height was recorded where 40% manure was applied. Clay loam soils significantly increased (p<0.05) ...

Rodade). In the greenhouse, five treatments were used: the control, where only water was added (M0), second control where ethanol 80 % was added (ME), moringa extract applied once at 2 weeks from emergence (M1), moringa extract applied at 2 and 4 weeks from emergence (M2), and moringa extract applied every 2 weeks to maturity,starting from two weeks from germination (M3).The same treatments were adopted in the field except the ME which was considered unnecessary after observing the results of the greenhouse experiment. Results showed that moringa extract increased growth and yield of tomato in both greenhouse and field. Moringa extract significantly increased above ground dry matter yield (DM), root dry matter weight and plant height for the crop. Yields obtained at MI, M2 and M3 were increasing in ascending order from M1....
