(1) Ke kumu o ka fertilization
1. E like me nā kūlana climatic a me ka ulu ʻana o ka lepo, e hoʻoholo i ka hua i manaʻo ʻia, e hoʻonui i ka hoʻokomo ʻana o nā mea kanu nitrogen a me ka phosphorus, e hoʻopili pono i nā fertilizers potassium, a hoʻohui i nā micro-fertilizers i ka nui kūpono e pili ana i nā kūlana meaʻai lepo.
2. E paipai i ka nui o ka mauʻu e hoʻihoʻi ʻia i ke kula, e hoʻonui i ka hoʻohana ʻana i ka mea kanu organik, a hui pū i nā mea kanu a me nā mea ʻole e hoʻomaikaʻi i ka momona o ka lepo, hoʻonui i ka hana a hoʻomaikaʻi i ka maikaʻi.
3. E hoʻohui i ka nitrogen, ka phosphorus a me ka potassium, e hoʻopili i ka mea hoʻomomona kumu i ka wā mua, a e hoʻopili pono i ka lole luna.E mālama pono i ka hoʻohana ʻana i ka fertilizer basal a me ka maikaʻi o ka lūlū ʻana e hōʻoia i ka maʻemaʻe, piha a ikaika nā mea kanu.Hiki i ka topdressing manawa kūpono ke pale i ka palaoa mai ka ulu nui ʻana a me ka noho ʻana i ka wā mua, a me ka de-fertilization a me ka hōʻemi ʻana i ka hua ma ka pae hope.
4. ʻO ka hui pū ʻana o ka lole luna a me ka irrigation.E hoʻohana i ka wai a me ka mea hoʻohuihui a i ʻole ka lole ʻaʻahu ma mua o ka hoʻoinu ʻana, a e pīpī i ka zinc, boron a me nā mea hoʻomoʻa ʻē aʻe i ka wā booting.
(2) Manaʻo fertilization
1. Manaʻo i ka 17-18-10 (N-P2O5-K2O) a i ʻole ke ʻano like, a e hoʻonui i ka hoʻohana ʻana i ka manure mahiʻai ma 2-3 cubic mika/mu inā ʻae nā kūlana.
2. ʻO ka pae hua ma lalo o 300 kg / mu, ʻo ka fertilizer kumu he 25-30 kg / mu, a ʻo ka top-dressing urea he 6-8 kg / mu i hui pū ʻia me ka irrigation mai ka wā piʻi a hiki i ka manawa hui.
3. ʻO ka pae puka he 300-400 kg / mu, ʻo ka fertilizer kumu he 30-35 kg / mu, a ʻo ka top-dressing urea he 8-10 kg / mu i hui pū ʻia me ka irrigation mai ka wā piʻi a hiki i ka manawa hui.
4. ʻO ka pae hua he 400-500 kg / mu, ʻo ka fertilizer kumu he 35-40 kg / mu, a ʻo ka top-dressing urea he 10-12 kg / mu i hui pū ʻia me ka irrigation mai ka wā piʻi a hiki i ka manawa hui.
5. ʻO 500-600 kg / mu ka pae puka, ʻo 40-45 kg / mu ka mea momona kumu, a ʻo ka urea top-dressing he 12-14 kg / mu i hui pū ʻia me ka irrigation mai ka wā piʻi a hiki i ka wā hui.
6. ʻOi aku ka nui o ka hua ma mua o 600 kg / mu, ʻo ka fertilizer kumu he 45-50 kg / mu, a ʻo ka top-dressing urea he 14-16 kg / mu i hui pū ʻia me ka irrigation mai ka wā piʻi a hiki i ka wā hui.
