Effect of Staking and Pruning on the Growth and Yield of Cucumber (Cucumis Sativus L.)

A field trial was conducted to evaluate the effect of pruning and staking on the vegetative growth and yield of cucumber ( Cucumis sativus L.). The experiment was a 3 x 2 factorial laid out in Randomized Complete Block Design (RCBD) with five replications. The results showed that vine length, number of flowers, total number of fruits and the number of non-marketable fruits were higher on the nonstaked treatment while staking resulted in a higher number of marketable fruits, weight, length and diameter of fruits. The unpruned plants produced the highest total number of fruits, marketable andnon-marketable fruits while the weight, length and diameter of fruits were highest on one stem pruning. Staking, pruning and their interaction had no significant effect on the number of days to 50% anthesis. In Abakaliki agro-ecological zone, non-staking and non-pruning treatments producedoptimum marketable yield of cucumber

Effect of Mulching and Nitrogen Fertilizer on Growth and Yield of Okra (Abelmoschus esculentus)

A field experiment was carried out in 2008 cropping season at the experimental farm of the faculty of Agriculture and Natural Resources Management to evaluate effect of different rates of nitrogen (0,70, 140, 210 kg N/ ha) and mulching (grass mulch) on the vegetative growth and green pod yield of okra. The experiment was conducted as a 4 x 2 factorial laid out in Randomized Complete Block Design (RCBD) with four replications. The results showed that nitrogen rate of 140kgN/ha producedthe highest number of branches and leaves. Days to 50% anthesis (flowering) was longest at 140 kg N/ha and shortest where nitrogen was omitted. Mulched plots, which received 140 kg N/ha produced the highest number of fruits. The weight and length of fruits was higher on the mulched plots. Non– mulched plots consistently produced least values in all the parameters that were measured
