On the other hand, when the number of plants per unit area decreased, the yield also decreased. Field trials were therefore conducted to study the effects of four plant densities, varying from 2.0 to 12.5 plants m-2 on water and radiation use and performance of two Masakwa . The soybean cyst nematode (SCN) (Heterodera glycines Ichinohe) is a significant yield-limiting factor in soybean production in the Midwestern US. Field experiments were conducted to evaluate plant population and N-fertilizer effects on yield and yield components of maize (Zea mays L.).Three levels of plant populations (53000, 66000, and 800000 plants ha 1 corresponding to spacings of 75 25, 60 25, and 50 25 cm) and 4 doses of N (100, 140, 180, and 220 kg ha 1) were the treatment variables. The seed yield of bean is the result of many plant growth processes which ultimately influence the yield components such as pods/plant, seeds/pod, and unit weight of seed.

A possible genetic characteristic conducive to low optimal plant population is greater partitioning of dry matter into branches within the canopy. Timmo) were aged they showed delayed field emergence and slower seedling growth. Over-accumulation of salt in rice plants is an effect of salt stress which decreases growth and grain yield. The obtained consequences recorded a significant effect in the vegetative characters at LSD 5% which are as follows: plant length (1.58 and 1.89), root length (2.09 and 1.42), number of leaves per .
