“…Later, it happened premature fall of the affected leaves, beginning of the apical part down. Similar results were observed by Rosolem and Bastos (1997), however without fall of the leaves in cotton plant, on the other hand, Ohki (1973) described the fall of leaves in the absence of the nutrient in the culture of the cotton.…”

Within the increase of Coffee production and its export as well, a larger resourcefulness is been required to manufacture its bags. Due to these increases, a natural fiber source became valued again despite its growing had been forgotten for some years. The mallow is being observed as an excellent ecological alternative, but the knowledge of its handling and natural requirements are restricted, by the fact of lately inattention in this natural fiber. In this context with the purpose of contributing with the knowledge of this cultivation, an experiment was settled aiming to evaluate its growth, to characterize the visual of macro and micronutrients deficiency symptoms to determine the analytical levels of these nutrients. The mallow plants, variety BR-01, were cultivated in the Department of Soil’s greenhouse from Universidade Federal Rural da Amazônia-UFRA, in plastic vases containing 3 kg of ground silica and submitted to the following treatments: complete, omission of N, omission of P, omission of K, omission of Ca, omission of Mg, omission of S, omission of B, omission of Cu, omission of Fe, omission of Mn and omission of Zn. After a period comprehended between 7 and 29 days, the occurrence of deficiency symptoms has started, except for the treatments with omission of S, Cu and Zn. The plants development were mostly affected by the treatments with omission of B and Ca.

“…Under very severe Mn stress conditions, treatments l, 2, 12, and 13, Zn concentrations of blades 1 and 2 ranged from 63 to 102 1 _,gjg while Mn concentrations were less than 5 0 gjg (Table 1). When Mn was supplied at 50 0 gjliter (treatments 6 and 17) where growth was no longer depressed by low Mn (12), Zn concentrations of blades l and 2 continued to decrease to 32 to 49 0 gjg while Mn concentrations ranged from 7 to 10 J.tg/g in blade tissue. In relation to growth, this is at the inflection point between deficiency and adequacy indicated by the 10 p.gjg critical Mn level reported earlier (13).…”

“…A 2 X II factorial greenhouse experiment was conducted on upland cotton 'Coker 310' including two B levels of 35 and 500 !Lg/liter and II Mn levels from 0 to 4,000 fLg/liter in nutrient solution indicated in Table I. The methods used in this experiment are the same as those reported previously (12). Three seedlings were transplanted into 10 liters of nutrient solution, and were harvested 36 days following transplanting when plants were in the early-square stage_ At harvest total fresh weight of shoots separated immediately above the fibrous root zone was 1•ecorded.…”

Interactions involving macro and micronutrients modify plant growth, as indicated by induced deficiencies or toxicities and growth reductions. The objective of this study was to determine the influence of Mn and B and their interactions on micronutrients in leaf tissues of upland cotton (Gossypium hirsutum L.). A 2 ✕ 11 factorial design included two B levels of 35 and 500 µg/liter and 11 Mn levels, varying from 0 to 4000 µg/liter in nutrient solution under greenhouse conditions. In blade 3, Mn tissue concentration less than the 10 µg/g critical level induced high Zn concentration of 127 µg/g in leaf tissue. As Mn concentration approached the critcial level, Zn concentrations decreased to 33 µg/g and remained constant with increasing Mn to 247 µg/g. Copper concentration was independent of Mn concentration. However, the reciprocal Mn‐Fe relationship was apparent where Mn concentrations of 4 and 247 µg/g were associated with Fe concentrations of 270 and 51 µg/g, respectively. Manganese nutrition had a small but significant influence on P concentrations where P concentrations of 2.37 and 1.84% were associated with Mn concentrations of 8 and 210 µg/g, respectively. The influence of B levels on micronutrient concentration in leaf tissue was not consistent. Low B induced lower Mn concentrations than did adequate B in young and recently matured tissue, whereas no effect of B levels on Mn concentration was evident in older leaf tissue. Low B induced a small but significantly lower Zn concentration in recently matured blades, while no effect of B nutrition on Cu was observed. However, low B induced higher Fe concentrations in old blades than did adequate B.

“…Many other researchers also observed B deficiency-induced cotton growth impairments such as reduction in plant height and internodal distance (Hinkle and Brown 1968;Ohki 1973;Zhao and Oosterhuis 2003), lesser main-stem nodes and squares, shorter fruit branches, deformed leaves (Hinkle and Brown 1968), bended petioles, and necrotic pith (Zhao and Oosterhuis 2003 …”

Boron (B) deficiency hampers cotton (Gossypiumhirsutum L.) growth and productivity globally, especially in calcareous soils. The crop is known as a heavy feeder of B; however, its reported plant analysis diagnostic norms for B-deficiency diagnosis vary drastically. In a 2-year field experiment on a B-deficient [hydrochloric acid (HCl)-extractable 0.47 mg B kg −1 ], calcareous, Typic Haplocambid, we studied the impact of soil-applied B on cotton (cv. CIM-473) growth, productivity, plant tissue B concentration, and seed oil composition. Boron was applied at 0.0, 1.0, 1.5, 2.0, 2.5, and 3.0 kg B ha −1 , as borax (Na 2 B 4 O 7 ·10H 2 O), in a randomized complete block design with four replications, along with recommended rates of nitrogen (N), phosphorus (P), potassium (K), and zinc (Zn). Boron use improved crop growth, decreased fruit shedding, and increased boll weight, leading to seed cotton yield increases up to 14.7% (P < 0.05). Improved B nutrition of plants also enhanced seed oil content (P < 0.05) and increased seed protein content (P < 0.05). Fiber quality was not affected. Fertilizer B use was highly cost-effective, with a value-cost ratio of 12.3:1 at 1 kg B ha −1 . Fertilizer B requirement for near-maximum (95% of maximum) seed cotton yield was 1.1 kg B ha −1 and HCl-extractable soil B requirement for was 0.52 kg ha −1 . Leaf tissue B requirement varied with leaf age as well as with plant age. In 30-day plants (i.e., at squaring), B-deficiency diagnosis critical level was 45.0 mg kg −1 in recently matured leaves and 38.0 mg kg −1 in youngest open leaves; at 60 days old (i.e., at flowering), critical concentration was 55.0 mg kg −1 in mature leaves and 43.0 mg kg −1 in youngest leaves. With advancement in plant age critical B concentration decreased in both leaf tissues; that is, in 90-day-old plants (i.e., at boll formation) it was 43.0 mg kg −1 in mature leaves and 35.0 mg kg −1 in the youngest leaves. As critical concentration range was narrower in youngest leaves (i.e., 35-43 mg kg −1 ) compared with mature leaves (i.e., 43-55 mg kg −1 ), B concentration in youngest leaves is considered a better indicator for deficiency diagnosis.
