LESSON 5.40 CORN - INCREASE YIELD AND REDUCE PRODUCT COSTS

 

Increase Corn Yield & Reduce Product Costs

You can increase your yield and reduce your cost of production by reducing water stress through

Maximizing Output (Yield)./. Minimizing Inputs (cost of production) = Maximizing Profit

As the table below shows, permanent yield loss occurs depending on the stage of growth. Water stress during pollination can lead to permanent yield loss of 8.0% per day. In today’s competitive environment, this amount of yield loss can lead to lower production and less profit.

Yield loss per day due to water stress        

Growth Stage / Evapotranspiration Inches Per Day /

 Est. Yield Loss % Per Day      (min – avg – max)

V12–V16            / 0.21 Inches  / 2. 1– 3.0 – 3.7 %

V16–Tasseling  / 0.33 Inches / 2.5 – 3.2 – 4.0 %

Pollination (R1) / 0.33 Inches / 3.0 – 6.8 – 8.0 %

Blister (R2)     / 0.33 Inches / 3.0 – 4.2 – 6.0 %

Milk (R3)        / 0.26 Inches  / 3.0 – 4.2 – 5.8 %

Dough (R4)    / 0.26 Inches / 3.0 – 4.0 – 5.0 %

Dent (R5)       / 0.26 Inches / 2.5 – 3.0 – 4.0

Maturity (R6)  / 0.23 Inches / 0

 

Choosing the Right Irrigation Method

There are three main options for irrigation of corn:

furrow (flood),

sprinkler (pivot or lateral move), or

drip (on-surface or subsurface).

Throughout this lesson, you will discover the many unique advantages drip irrigation provides for both increasing your yield and minimizing your inputs.

 Maximize Your Land with Drip Irrigation

 

If you have 10 ha of land and you chose to irrigate with centre pivots, 21.46% (2,2 ha) of your land would not be irrigated due to pivots not reaching the corners.

SOMO LA 5.40 MAHINDI - ONGEZA MAVUNO NA KUPUNGUZA GHARAMA ZA BIDHAA
 
Ongeza Mavuno ya Mahindi & Punguza Gharama za Bidhaa
 
Unaweza kuongeza mavuno yako na kupunguza gharama yako ya uzalishaji kwa kupunguza shinikizo la maji kupitia
Kuongeza Pato (Mavuno)/. Kupunguza Pembejeo (gharama ya uzalishaji) = Kuongeza Faida
Kama jedwali hapa chini linavyoonyesha, upotevu wa kudumu wa mavuno hutokea kulingana na hatua ya ukuaji. Mkazo wa maji wakati wa uchavushaji unaweza kusababisha hasara ya kudumu ya mavuno ya 8.0% kwa siku. Katika mazingira ya kisasa ya ushindani, kiasi hiki cha hasara ya mavuno kinaweza kusababisha uzalishaji mdogo na faida ndogo.
 
Kupoteza mavuno kwa siku kutokana na matatizo ya maji
 
Hatua ya Ukuaji / Inchi za Evapotranspiration Kwa Siku /
  Est. Hasara ya Mavuno % Kwa Siku (dakika - wastani - max)
V12–V16 / Inchi 0.21 / 2. 1– 3.0 – 3.7 %
V16–Tasseling / Inchi 0.33 / 2.5 – 3.2 – 4.0 %
Uchavushaji (R1) / Inchi 0.33 / 3.0 - 6.8 - 8.0 %
Malengelenge (R2) / Inchi 0.33 / 3.0 - 4.2 - 6.0 %
Maziwa (R3) / Inchi 0.26 / 3.0 - 4.2 - 5.8 %
Unga (R4) / Inchi 0.26 / 3.0 - 4.0 - 5.0 %
Kinyesi (R5) / Inchi 0.26 / 2.5 - 3.0 - 4.0
Ukomavu (R6) / Inchi 0.23 / 0
 
Kuchagua Njia Sahihi ya Umwagiliaji
Kuna chaguzi tatu kuu za umwagiliaji wa mahindi:
mfereji (mafuriko),
kinyunyizio (pivot au lateral move), au
drip (juu ya uso au chini ya ardhi).
Katika somo hili lote, utagundua faida nyingi za kipekee za umwagiliaji kwa njia ya matone hutoa kwa kuongeza mavuno yako na kupunguza pembejeo zako.
 
Ongeza Ardhi Yako kwa Umwagiliaji wa Matone
 
Ikiwa una hekta 10 za ardhi na ukachagua kumwagilia maji kwa kutumia mihimili ya katikati, 21.46% (ha 2,2) ya ardhi yako haitamwagiliwa kwa sababu ya mihimili kutofika kwenye pembe.
