LESSON 5.14 POTATOES - CHEMIGATION WITH DRIP

Accurately apply Chemigation with Drip

Application on N, P, K, Ca, Mg, S, B, Mn, and Zn have a direct impact on yield, tuber number, dry matter, internal structure, skin, storage potential, cooking potential, and tuber strength.
To produce a crop that is ‘in-spec’ for its final market, you need to get all these nutrients right using the right amount at the right time and at the right location. Too much nitrogen for example, and you increase your foliage while decreasing dry matter and starch.
One of the major benefits of SUBSURFACE DRIP IRRIGATION is the ability to apply chemigation (fertilizer, herbicides, insecticides, and fungicides) accurately and effectively by injecting it into the irrigation system itself. Fertilizer, insecticides, and fungicides are easily applied directly to the root zone with over 90 % uniformity, without manual labour or tractor use.
Sprinklers do not provide this flexibility or accuracy and you need a tractor to apply the nutrients, which requires more resources (fuel, equipment, and labour) and is less efficient as nutrients are lost.
Additionally, sprinklers increase humidity and increase the risk of black leg disease. Sprinkler also irrigate the interrow so that additional weed control is required, and foliage is wet increasing the risk of late blight and target spot. Worse yet, sprinklers wash off the fungicide that has been applied so you are not protecting your plants completely, while wasting valuable fungicide that runs off into the soil.

Queensland Australia study shows:
SUPSURFACE  DRIP IRRIGATION  Solution , T-Tape 510-30-340 , 180 m row lengths, 1% downhill slope , Row spacing 0,8 m , 1 drip lateral per row, Application: 4,5 mm of water per hour at 1.0 bar.
This archieved 50 % water savings and 25% yield increase compared to blocks irrigated with sprinkler:

IRRIGATION METHODE	TONNAGE YIELD	WATER USE.
Overhead sprinkler	37,2 t /ha	5,0 (MI/ha)
UNDERGROUND IRRIGATION	50,8 t/ha	3,0 (MI/ha)

More money in your pocket….
As the table on the following page shows the UDI block produced 36 % more revenue per hectare compared to sprinkler irrigation. Additionally, using drip irrigation, the client harvested a higher percent of larger and more uniform potatoes (compared to using sprinklers

KILIMO BORA
SOMO LA 5.14 VIAZI - KEMIGATION KWA DRIP
Weka kwa usahihi Chemigation na Drip
Utumizi kwenye N, P, K, Ca, Mg, S, B, Mn, na Zn una athari ya moja kwa moja kwenye mavuno, nambari ya kiazi, mabaki kavu, muundo wa ndani, ngozi, uwezo wa kuhifadhi, uwezo wa kupika, na nguvu ya kiazi.
Ili kuzalisha zao ambalo ni 'in-spec' kwa ajili ya soko lake la mwisho, unahitaji kupata virutubisho hivi vyote kwa kutumia kiasi kinachofaa kwa wakati unaofaa na mahali pazuri. Nitrojeni nyingi sana kwa mfano, na unaongeza majani yako huku ukipunguza mabaki kavu na wanga.
Moja ya faida kuu za UMWAGILIAJI WA SUBSURFACE DRIP IRRIGATION ni uwezo wa kupaka kemikali (mbolea, dawa, dawa za kuua wadudu na kuvu) kwa usahihi na kwa ufanisi kwa kuidunga kwenye mfumo wa umwagiliaji wenyewe. Mbolea, dawa za kuua wadudu na viua kuvu huwekwa kwa urahisi moja kwa moja kwenye eneo la mizizi kwa zaidi ya 90% ya usawa, bila kazi ya mikono au matumizi ya trekta.
Vinyunyiziaji havitoi unyumbulifu huu au usahihi na unahitaji trekta ili kupaka virutubishi, jambo ambalo linahitaji rasilimali zaidi (mafuta, vifaa na kazi) na haifanyi kazi kwa ufanisi kwani virutubishi hupotea.
Zaidi ya hayo, wanyunyiziaji huongeza unyevu na huongeza hatari ya ugonjwa wa mguu mweusi. Vinyunyiziaji pia humwagilia kwenye makutano ili udhibiti wa magugu unahitajika, na majani kuwa na unyevu na hivyo kuongeza hatari ya kuchelewa kwa baa na sehemu inayolengwa. Mbaya zaidi, vinyunyiziaji huosha dawa ya ukungu ambayo imetumiwa ili usilinde mimea yako kabisa, huku ukipoteza dawa muhimu ya kuvu inayoingia kwenye udongo.

Utafiti wa Queensland Australia unaonyesha:
Suluhisho la Umwagiliaji wa matone ya SUPSURFACE, T-Tape 510-30-340, urefu wa mstari wa 180 m, mteremko wa 1%, Nafasi ya safu 0.8 m, 1 drip lateral kwa kila safu, Maombi: 4.5 mm ya maji kwa saa kwa 1.0 bar.
Hifadhi hii ya maji iliyohifadhiwa kwa 50% na ongezeko la mavuno 25% ikilinganishwa na vitalu vilivyomwagilia kwa vinyunyizio:
NJIA YA UMWAGILIAJI MATUMIZI YA MAJI MAVUNO YA TONI.

Kama jedwali kwenye ukurasa ufuatao linavyoonyesha kitengo cha UDI kilizalisha mapato zaidi ya 36% kwa hekta ikilinganishwa na umwagiliaji wa vinyunyiziaji. Zaidi ya hayo, kwa kutumia umwagiliaji kwa njia ya matone, mteja alivuna asilimia kubwa ya viazi vikubwa na sare zaidi (ikilinganishwa na kutumia vinyunyuziaji)
