Welcome to another of our
article that promised to be very enlighten. I came up with this topic against
the backdrop of the fact that I see many vegetable farmers and those intending
to be not having understanding of quantity of seeds they actually need to cover
the area of land they want to cultivate. Also many can’t calculate plant
population which makes them to either over plant or under plant the field both
of which have grave consequences. This simple knowledge among others I would be
sharing in this article would go a long way to determine the profit margin and
losses as the case may be.
PLANT POPULATION/COST OF
PRODUCTION
Plant population is one of the
keys to successful vegetable farming exercise. For every area of land you are
intending to cultivate, there is a specific quantity of seeds you are required
to plant though this is subjected to your planting distance. The planting
distance however is a subject of the season you are in. I would give a
hypothetical scenario common to our farmers to explain this. Let’s assume a farmer with good understanding of plant population required to plant 5000 plant stands per an acre, he ends up planting this population in the nursery, unfortunately, he attained 85% germination rate which left him with 4250 to be transplanted. After transplanting, he lost some stands to mechanical damage and diseases/pest attack. Eventually, he is left with 3500 stands that grow to fruiting stage from which he cash back his investment. So let look at some activities along the line that determines his profit/loss margin:

So let look at some activities along the line that determines his profit/loss margin:
Cost of labour for weeding
Cost of labour for wetting and fueling if need
be
Cost of labour for spraying of chemicals
You would agree with me that
for these activities, the farmer spends the same amount per acre for labour
cost if he has 5000 stands as he spends on 3500 stands. This translates into
the fact that the farmer is spending on 1500 plant stands that do not exist.
Waste!!! This is exactly what most vegetable farmers do.
On the other hand, if the
farmer over-planted the field with the aim of making more money, he ends up with
lesser yield which translates into less income. This underscores the importance
of plant population of a particular vegetable type. Summarily, if the plant
population isn’t gotten right, the farmer ends up spending more on the cost of
production.
VEGETABLE TYPES AND NUMBER OF SEEDS PER GRAM
Seeds whether hybrids or OP
are often sold in gram except for some companies like Sygenta that sells in
seed counts. The weight of a particular vegetable seeds varies from another as
the number of seeds per gram. I would be sharing with you the average number of
seeds per gram and the number of stand expected to be planted on an acre for
each of the major vegetables.
Tomato
Average seeds/gram: 300 seeds
Average seeds/acre: 50 gram of
seeds/15000 seeds
Spacing: 60 x 45 cm (dry
season)
Summarily, it is expected that
you are to plant 15000 stands on an acre during dry season with that spacing
above but during raining season, it is advisable you use a more spacious
spacing say 60 x 100 cm in order to ensure adequate ventilation. In addition, if
you require transplanting 15000 stands for on an acre, then you are expected to
nurse at least 18,000 seeds in your nursery to cater for germination percentage
which is usually put between 80%-85%.
Cucumber
Average seeds/gram: 30 seeds
Average seeds/acre: 400 gram of
seeds/12000 seeds
Spacing: 60 x 60 cm
Summarily, the spacing above
could do for both wet and dry season provided you stake your plants. Staking
increases yield no doubt and produces fruits with great market appeal. Cucumber
does not require nursery but you have to make provision for those that might
not germination by planting at least 15% more than the seeds you needed in an
adjacent plot (Please, you need not space them as the one on the field), then
transplant them to replace those that do not germinate on the field. (Note,
this is applicable to all vegetables that do not require nursery and you wish
to maximize plant population)
Watermelon
Average seeds/gram: 10 seeds
Average seeds/acre: 400 gram of
seeds/4000 seeds
Spacing: 80 x 100 cm
Summarily, the spacing above
could do for both wet and dry season both during dry season; you need to take
more measures to prevent fruit rotting. Watermelon, does not require nursery
but you have to make provision for those that might not germination by planting
at least 15% more than the seeds you needed in an adjacent plot (Please, you
need not space them as the one on the field), then transplant them to replace
those that do not germinate on the field.
Sweet pepper/Egg plant
Average seeds/gram: 115 seeds
Average seeds/acre: 125
gram/14000 seeds
Spacing: 60 x 45 cm
Summarily, if you require
transplanting 14000 stands for on an acre, then you are expected to nurse at
least 17,000 seeds in your nursery to cater for germination percentage which is
usually put between 80%-85%.
Hot pepper
Average seeds/gram: 250 seeds
Average seeds/acre: 48 gram/12000 seeds
Spacing: 60 x 45 cm
Summarily, if you require transplanting 12000 stands for on an acre, then you are expected to nurse at least 15,000 seeds in your nursery to cater for germination percentage which is usually put between 80%-85%.
Onion
Average seeds/gram: 300 seeds
Average seeds/acre: 1000 -1500
gram/390,000 seeds
Spacing: (20-30) x (5-10) cm
Onion requires nursery and
also making provision for germination percentage. Please note that there are
wet season onion varieties but beds most be made during wet season.
Carrot
Average seeds/gram: 1000 seeds
Average seeds/acre:
1500 gram/150,000 seeds
Spacing: 30 cm x drill
Cabbage
Average seeds/gram: 400 seeds
Average seeds/acre: 50
gram/20,000 seeds
Spacing: 45 x 45 cm
Okra
Average seeds/gram: 12 seeds
Average seeds/acre: 2500
gram/30,000 seeds
Spacing: 45 x 30 cm

COST OF SEEDS AND SEED COMPANIES
Now that I have analyzed
different seeds count above, you must have been thinking: must I buy all the
seeds require to cultivate an acre? No, you don’t need to. Seeds are sold in
different packs to suit your want. You have the following measurement: 1 gram
pack, 2.5 gram pack, 5 gram pack, 10 gram pack, 50 gram pack, 100 gram pack and
even 500 gram pack.
However, the law of economics
applies, the more you buy the less you pay. A 5 gram of a particular variety of
tomato seeds could sell for N 1000 while 50 gram of same sells for N 6000 instead
of expected N 10, 000. If you however want to plant on a small space, it is
advisable you buy smaller pack as storing of seeds especially for a relatively
long period isn’t advisable.
Moreover, a company could sell
its hybrid seed (let’s say 10 g) of tomato for N 4, 600 while another sells hers
for N 8, 000. You might think you would go for a lesser price but I can tell you
that the more expensive seeds ‘most of the time’ have better attributes. I would
rather suggest you buy seeds on recommendation and or considering its attributes such as
resistance to diseases and the season it is meant to be cultivated, yield
potential etc.
SEEDS EXPIRING DATE
This is also as important as
your money. Do you remember the germination percentage mentioned above? The
closer a seed pack to its expiring date, the less likely you would get good
germination percentage. That means when buying seeds, watch out for its
expiring date!
